Testosterone cypionate vs enanthate: for most men on TRT, neither is better. Both deliver the same testosterone, and your prescriber sets the dose. The real differences are practical: the oil in the vial, inactive ingredients, product format, price, supply, and one device. Only enanthate comes as an FDA-approved under-the-skin pen. And switching isn't milligram-for-milligram.

That's the fast answer. Here's what nearly every other comparison misses: the ester is usually the smallest decision you're making. The bigger question is whether the product in your hand is FDA-approved at all. The online TRT programs we checked use compounded testosterone, which isn't. You can often tell in about ten seconds just by reading which oil is on the label. We'll show you how.

The choice really matters if you're allergic to sesame or cottonseed · your pharmacy is out of one · you pay cash and price matters · you'd rather use a pen than a vial and syringe · you plan to have kids (then both matter, so read the fertility section first).

TRT Provider Guide is the independent decision resource for testosterone replacement therapy — helping U.S. adults understand how low testosterone is evaluated, compare online and local care models and providers, and choose the next step that fits their health needs, fertility plans, budget, state, and care preferences, with every material claim verified and dated.

This page is for you if you're on injectable testosterone or about to start, your pharmacy or clinic switched you or offered a different ester, you're checking oils because of an allergy or a reaction, or you're pricing vials.

Start somewhere else if low testosterone hasn't been confirmed with blood tests yet (jump to diagnosis), you want children in the next year or two (read fertility first), or you're looking for bodybuilding or "cycle" advice. We don't give it.

Who this covers: adult men being treated for low testosterone. Transgender and gender-diverse people use the same products under different care standards. A gender-affirming clinician is the right guide there, and the programs named on this page aren't set up for that care. Enanthate's only labeled use in women is for advanced breast cancer, directed by an oncologist.

The right TRT provider is not the same for every person — it depends on whether low testosterone has been properly evaluated, your symptoms and health history, your fertility plans, your state, your insurance or cash-pay preference, your treatment-format preference, your budget, and whether online or in-person care is the better starting point. Some situations belong with primary care, urology, endocrinology, reproductive urology, or urgent or emergency care when the symptoms warrant it. Because a general answer cannot resolve those for you, use TRT Provider Guide's Find My TRT Path tool to map your situation to the right care route and the questions to ask before you pay.

Which should you choose: testosterone cypionate or enanthate?

Short answer: For most men, the best choice is the one your prescriber writes and your pharmacy reliably stocks. That's often cypionate when price and retail availability are the deciding factors, because current cash-price data and the broader U.S. supply base favor it. Enanthate makes sense when cottonseed oil is a problem, cypionate is out of stock, or you want the Xyosted pen. If your labs and symptoms are steady, don't switch just to switch.

You're not really choosing between two hormones. You're choosing between products. So start with the problem you're actually trying to solve.

If this is you… Usually the better fit Why Ask your prescriber or pharmacist
Starting TRT and paying cash at a retail pharmacy Often generic cypionate It is widely available and the current Drugs.com price guide lists a low‑cost 10 mL option "Which FDA‑approved product is on my formulary and in stock?"
Allergic to sesame Cypionate may avoid the sesame oil used in the FDA‑approved enanthate products reviewed The reviewed cypionate labels use cottonseed oil "Does anything in my product contain sesame?"
Reacted to a cottonseed‑based vial Ask about enanthate or another medically appropriate formulation The reviewed FDA‑approved enanthate products use sesame oil instead "What oil and inactive ingredients are in the replacement?"
Your pharmacy is out of cypionate Ask whether another manufacturer, vial size, pharmacy, or a different prescribed product is appropriate Cypionate remains on ASHP's shortage list "What FDA‑approved option is available without interrupting care?"
You want a pen rather than a vial and syringe Xyosted may be worth discussing It is an FDA‑approved testosterone enanthate autoinjector for subcutaneous use "Is Xyosted appropriate for me, and is it covered?"
You're stable on your current prescribed product Usually no reason to change only because another ester is popular online A switch adds a new product, formulation and monitoring variable "Is there a clinical reason to change?"
You want children now or in the near future Discuss fertility before testosterone treatment Exogenous testosterone can suppress spermatogenesis "Should I see a reproductive urologist before treatment?"
You want insurance to pay for the medication Start with an FDA‑approved product through a pharmacy your plan covers Coverage and prior authorization are plan‑specific; compounded products are not FDA‑approved "Which product is on my formulary, and what approval steps apply?"

The 6 real differences between cypionate and enanthate

Short answer: Chemically, only the "tail" attached to the testosterone differs. Cypionate's tail is a bit heavier, so 100 mg of cypionate holds about 70 mg of testosterone versus about 72 mg in enanthate. The other differences live on the labels: the oil, the preservative, the package, the devices, the price, and how many companies make each one.

What an ester is, in one minute

An ester is a fatty "tail" bolted onto testosterone. It lets the hormone dissolve in oil and seep out of the injection site slowly instead of all at once. Your body clips the tail off. What's left is plain testosterone, the exact same molecule whichever ester you started with.

Cypionate's tail has eight carbon atoms, some of them in a ring. Enanthate's is a straight chain of seven. That small size gap is the whole chemical story.

Difference 1: how much testosterone is in each milligram

Compound Molecular weight Share that is testosterone Testosterone moiety in 100 mg of ester*
Testosterone itself 288.42 100% —
Testosterone cypionate 412.61 69.9% About 70 mg
Testosterone enanthate 400.59 72.0% About 72 mg

Derived from molecular weights. This is a chemistry comparison, not a dose-conversion instruction.

Enanthate delivers about 3% more testosterone per milligram. That's real, it's small, and it's one reason a switch shouldn't be done by copying the number from your old prescription. (Our arithmetic, using the molecular weights printed on the FDA labels. It's chemistry, not a dose conversion.)

Differences 2 to 6, at a glance

  1. Half-life on the label. The cypionate labels print about eight days. The enanthate vial labels print none. See why the online numbers disagree.
  2. Oil and preservative. Cottonseed oil plus benzyl alcohol, versus sesame oil plus chlorobutanol. See what's in each product.
  3. Forms. Cypionate comes in 1 mL and 10 mL vials, plus Azmiro's single-dose vial and prefilled syringe. Enanthate comes in one 5 mL vial and the Xyosted pen. See the pen.
  4. Price per milligram. Cypionate was cheaper at every price level we checked. See the numbers.
  5. Who makes it. Cypionate has multiple current manufacturer and repackager listings, while the generic enanthate vials we reviewed are from Hikma and Eugia. See the supply picture.

What's the same (more than you'd think)

  • The timing language. Both vial labels say the drug "can be given at intervals of two to four weeks." The enanthate label adds that shots more often than every two weeks are "rarely indicated." Current practice often uses weekly or every-two-week schedules, and the Endocrine Society's 2018 guideline lists "testosterone enanthate or cypionate" together as one option.
  • The warnings. Blood pressure, red blood cells, blood clots, the prostate and sperm production.
  • The legal status. Both are Schedule III controlled substances.
  • The rule before starting. Confirm low testosterone with morning blood tests on at least two separate days.

What the table tells you: these are near-twins in different packaging. The differences that touch your daily life are the oil, the preservative, the package size and one under-the-skin pen. Price and supply come next.

Does cypionate really last longer than enanthate?

Short answer: Maybe a little, but not in a way that matters once a prescriber sets your schedule. The cypionate labels print a half-life of about eight days. The enanthate vial labels print none. The "4.5-day" and "5-to-7-day" enanthate figures you'll see online come from older studies and clinic estimates, not from an FDA label.

A half-life is how long it takes your body to clear half of a dose. Longer half-life, slower fade.

Why the numbers online are all over the place

We found cypionate quoted at anywhere from 8 to 12 days and enanthate at anywhere from 4.5 to 11 days. One clinic's blog lists enanthate at about 5 days, about 7 days and 10 to 11 days, all in the same article. When numbers wobble that much, treat every one of them as a rough guess. The only figure printed on an FDA label is cypionate's "approximately eight days."

What actually changes how you feel: the gap between shots

Every long-acting shot rises, peaks, then fades until the next one. The longer the gap, the bigger the swing. That's the "great for a few days, dragging by shot day" pattern a lot of men describe. Both vial labels describe the same slow release from an oil depot, and researchers have documented exactly this high-then-low pattern with enanthate shots given every few weeks.

So if you're riding peaks and crashes, the ester is rarely the lever. The interval and the route are. That's a conversation with your prescriber, not a reason to trade esters on your own.

Oils, preservatives, allergies and injection pain

Short answer: FDA-approved enanthate (both the vial and Xyosted) is made with sesame oil. FDA-approved cypionate uses cottonseed oil. The preservatives differ too. No study has compared injection pain between the two FDA-approved vials, so if you've reacted to one, tell your prescriber exactly what its label lists.

What's in each product

Ingredient Depo‑Testosterone / reviewed generic cypionate Azmiro Generic enanthate vial Xyosted Compounded cypionate
Cottonseed oil Yes Yes — — Varies
Sesame oil — — Yes Yes Varies
Grapeseed oil — — — — Varies; some compounders use it
Benzyl benzoate Yes Yes — — Varies
Benzyl alcohol Yes Yes — — Varies
Chlorobutanol — — Yes, 5 mg/mL — Varies

FDA-approved products: current labels reviewed 20 September 2026. Compounded formulations vary by pharmacy and are not FDA-approved.

If you're allergic to sesame

Sesame became the ninth major food allergen in the U.S. under the FASTER Act, with labeling rules starting in 2023. Both FDA-approved enanthate products contain sesame oil, and Xyosted's label names sesame oil allergy as a reason not to use it. FDA-approved cypionate is cottonseed-based. If you have a sesame allergy, make sure it's in your chart before anyone swaps your product.

If cottonseed is the problem

Enanthate is the FDA-approved alternative. Compounded cypionate made in grapeseed or another oil exists, and some online programs use it by default, but it isn't FDA-approved. More on what that means below.

Injection pain: what's known, and what's just stories

Testosterone labels list pain and inflammation at the injection site as a possible reaction. That's where the evidence stops. There's no head-to-head pain study between the two FDA-approved vials.

Online, men blame the oil's thickness, the preservative, the injection site, the needle and the volume, and they blame them in both directions. Some swear enanthate hurts less. Others say it's worse. Those are individual reports, not evidence. If a new vial hurts more than your old one, photograph both labels and bring them to your prescriber.

When it's not normal soreness

Get medical help right away for hives, swelling that spreads, swelling of your face, lips or throat, or trouble breathing after a shot. Testosterone labels list allergic reactions, including severe ones. The enanthate vial labels also describe rare coughing fits and breathing trouble right after an injection. For chest pain or trouble breathing, call 911.

Your vial check card

Find the name on your box or pharmacy label, then read across. Screenshot it or print it for your pharmacist.

If your label says… FDA‑approved product type? Oil Other listed inactive ingredients Labeled route If you've reacted before, ask…
Depo‑Testosterone or an approved testosterone cypionate injection, USP Yes, when tied to an approved manufacturer/NDC Cottonseed Benzyl alcohol; benzyl benzoate Intramuscular "Could the inactive ingredients be contributing, and what approved alternatives fit me?"
Azmiro Yes Cottonseed Benzyl alcohol; benzyl benzoate Intramuscular "Is this single‑dose product appropriate and covered?"
Testosterone enanthate injection, USP 5 mL vial Yes, for the current Hikma/Eugia products reviewed Sesame Chlorobutanol Intramuscular "Does my chart list a sesame allergy?"
Xyosted Yes Sesame No preservative listed Subcutaneous abdomen "How will we monitor blood pressure, hematocrit and response?"
A pharmacy‑compounded testosterone product No; compounded drugs are not FDA‑approved Varies Varies Depends on the prescription "Which pharmacy made this, why is a compounded product being used, and exactly what is in it?"

The ten-second clue: the current FDA-approved cypionate labels we reviewed use cottonseed oil. If your cypionate lists grapeseed or another oil, that is a strong reason to check whether it is compounded. Oil alone does not prove approval status, so verify the manufacturer, NDC, and dispensing pharmacy.

Can you switch from cypionate to enanthate at the same dose?

Short answer: Don't assume so. A current FDA testosterone label (Azmiro's) says injectable testosterone products are "not substitutable on a milligram-per-milligram basis." If your pharmacy or clinic is switching you, your prescriber should write the new dose and schedule, and your blood work should be rechecked afterward.

If your pharmacy just called to say they're out, take a breath. This happens a lot, and it's fixable. Here's the calm version.

Why "same dose" is the wrong starting point

  • Different amount of testosterone. Enanthate carries about 3% more per milligram.
  • Different oil and preservative. That can change how the shot feels, and it matters if you have allergies.
  • Possibly a different route and schedule. A vial into the muscle every week or two isn't the same as a weekly pen under the skin.
  • Different person. How your levels respond is individual. That's what follow-up labs are for.

You'll find websites, and even a pharmacy-finder's briefing for prescribers, saying the two can be dosed the same. Sometimes a prescriber will do exactly that. The point is that it's their call, written on a new prescription, and checked with blood work. Not a guess at the counter.

What a well-managed switch looks like

  1. A new prescription written for the exact product: its name, strength and schedule.
  2. An oil and allergy check against the vial check card.
  3. A lab plan. Ask when your blood work will be rechecked after the switch.
  4. A short list of things to report, such as new swelling, big mood changes, an injection-site reaction, or feeling very different than before.
  5. A photo of your old label, so you and your next prescriber know exactly what you were on.

Can the pharmacist swap it at the counter?

In general, a pharmacist can switch you between makers of the same drug when they're rated equivalent, such as one company's cypionate for another's. Cypionate and enanthate are different drugs. Changing the ester needs your prescriber.

If you're about to run out

  • Call your prescriber now, not on the day you're empty.
  • Ask the pharmacy to check its other stores, or transfer the prescription somewhere that has stock.
  • Ask whether a different vial size, or the other ester, is an option. Either one needs a new prescription.
  • Don't stretch doses, share vials, or buy from any website that doesn't require a prescription.

Which is cheaper: testosterone cypionate or enanthate?

Short answer: In the current cash-price source we could verify, generic cypionate was cheaper per 100 mg in the common large vial. On 20 September 2026, Drugs.com's price guide listed cypionate 200 mg/mL at $35.75–$50.00 for 10 mL and enanthate 200 mg/mL from $36.17 for 5 mL. That works out to about $1.79–$2.50 versus about $3.62 per 100 mg of drug.

We compare the same amount of drug because raw vial prices can mislead you. A 10 mL cypionate vial contains twice as much solution as a 5 mL enanthate vial at the same 200 mg/mL concentration.

Product Package in current Drugs.com price guide Listed cash price Approx. price per 100 mg of drug
Generic cypionate 200 mg/mL 10 mL / 2,000 mg $35.75–$50.00 $1.79–$2.50
Generic cypionate 200 mg/mL 1 mL / 200 mg From $14.00 From $7.00
Generic enanthate 200 mg/mL 5 mL / 1,000 mg From $36.17 About $3.62

Cash-price snapshot checked 20 September 2026. Prices change by pharmacy, location and date and are not insurance quotes.

The twist: package size can reverse the comparison

A small 1 mL cypionate vial can cost more per 100 mg than a 5 mL enanthate vial. That is why "cypionate is cheaper" is useful only when the package, concentration and pharmacy are held constant enough to make a fair comparison.

Insurance and prior authorization

Coverage is plan-specific. FDA-approved generic cypionate or enanthate may be covered under some formularies, while brand-only Xyosted can face different coverage rules. Check the exact product, prior-authorization criteria, pharmacy network, deductible and copay with your plan instead of assuming one ester is always covered better.

The drug price is not the clinic price

A retail vial price does not include the clinician, diagnostic testing, follow-up labs or membership fees. Online TRT programs may bundle or separate those charges, so compare the complete first-year care cost on a provider-cost page rather than treating a vial coupon as the total cost of TRT.

See our testosterone cypionate cost and testosterone injections cost guides for care-model pricing.

Why is cypionate easier to find, and is there still a shortage?

Short answer: Cypionate has more U.S. manufacturer and repackager listings, but that does not guarantee that your pharmacy has it today. ASHP still listed testosterone cypionate injection as a shortage in September 2026; its September 3 update said Pfizer's Depo-Testosterone was on shortage because of manufacturing delays while several generic products were available.

Supply question Cypionate Enanthate
Current FDA‑approved U.S. products reviewed Multiple brand/generic manufacturer and repackager listings Current generic vial labels from Hikma and Eugia, plus Xyosted as a separate branded product
Common vial presentations 1 mL and 10 mL presentations exist 5 mL multidose vial for the generic products reviewed
Shortage signal ASHP still listed a cypionate shortage on 3 September 2026 No blanket "never in shortage" claim is safe; local stock can still vary
Best action when stock is uncertain Call the pharmacy before the refill date and involve the prescriber if a different product is needed Same

The useful conclusion is not "cypionate is always available." It is that cypionate has more approved supply sources, while actual stock remains local and time-sensitive.

When your pharmacy is out: call before you run out, ask whether another approved manufacturer or vial presentation is available, and ask your prescriber what to do if a different product is needed. Do not change ester, strength or schedule on your own.

What about Xyosted and under-the-skin shots?

Short answer: Xyosted is testosterone enanthate in a prefilled autoinjector used once weekly under the skin of the abdomen. Its July 2025 label removed the former boxed blood-pressure warning and removed age-related hypogonadism from the contraindications, but the label still keeps an age-related limitation of use and a blood-pressure warning. Regular cypionate and enanthate vials remain labeled for intramuscular use; subcutaneous use of those vials is off-label.

Why that 2022 study doesn't prove enanthate is "safer"

A 2022 study in the Journal of Urology followed 234 men. Men on cypionate injected into the muscle were compared with men on the enanthate pen under the skin. The pen group had lower estradiol and hematocrit after treatment. You'll see this cited as proof enanthate is gentler.

It isn't. The route, the device and the schedule all changed at once, so the study can't isolate what the ester did. If hematocrit or estradiol is your concern, the useful questions are about route and dosing interval, not about swapping esters.

Can regular vials go under the skin?

FDA-approved cypionate and enanthate vials are labeled for injection into the muscle. Using them under the skin is off-label, and it's increasingly common. A 2022 review in the Journal of Clinical Endocrinology & Metabolism called subcutaneous testosterone "a safe, practical, and reasonable option," and some online programs build their whole protocol around it. Whether it fits you is your prescriber's call, not a technique change to make on your own.

Other long-acting shots

Testosterone undecanoate (Aveed) is a different ester given in a clinic at long intervals, under a special safety program because of rare serious reactions right after injection. Our testosterone cypionate reviews page compares it with other formats.

Are the side effects and warnings different?

Short answer: Mostly no. Both carry the same class warnings: higher red blood cell counts, blood pressure increases, blood clots, prostate monitoring and lower sperm production. The label differences you'll notice come from when each label was last rewritten, not from the ester. And FDA labeling for testosterone is still changing in 2026.

The shared warning list

Warning/issue What it means in plain words What clinicians may monitor
Higher hematocrit / polycythemia Testosterone can raise red blood cell concentration Hematocrit before and during treatment
Blood pressure increases FDA now requires blood‑pressure risk information across testosterone products Blood pressure periodically
Venous thromboembolism Blood clots in the legs or lungs have been reported New leg swelling/pain or sudden breathing symptoms need prompt assessment
Prostate/BPH issues Label language is evolving; current product labeling and individual risk matter Symptoms and prostate evaluation when appropriate
Fluid retention Swelling can matter more in people with heart, kidney or liver disease Swelling, weight and related symptoms
Gynecomastia Breast enlargement can occur Symptoms
Reduced sperm production Exogenous testosterone can suppress spermatogenesis Fertility plans before treatment
Abuse/dependence Testosterone is a Schedule III controlled substance Prescriber monitoring and safe storage
Sleep apnea Some labels warn testosterone may worsen sleep apnea in people with risk factors Symptoms such as snoring and daytime sleepiness

Same drug, two paperwork eras

Xyosted's and Azmiro's current labels include results from TRAVERSE, a large heart-safety trial of testosterone gel in 5,198 men who had heart disease or several risk factors. Major heart events were similar with testosterone and placebo: 7.0% versus 7.3%.

The generic cypionate and enanthate vial labels we read still say long-term heart-safety trials "have not been conducted." That isn't a difference between esters. It's a difference in when labels get updated. FDA called for class-wide changes in February 2025. In June 2026, HHS asked FDA for another round: dropping the "age-related" limitation, narrowing the prostate-cancer contraindication to metastatic disease, and revising prostate-enlargement warnings. Requested doesn't mean every label has changed yet.

One more label note: Xyosted's label carries a warning about depression and suicidal thoughts, based on cases in its own trials (4 of 283 men). The vial labels list depression and anxiety among possible reactions too. Mood changes on any testosterone are worth reporting.

Call 911 or go to an emergency room for chest pain, shortness of breath, pain or swelling in one leg, swelling of your face or throat, or a severe allergic reaction. Get urgent care for an erection that won't go away.

Do cypionate and enanthate affect fertility differently?

Short answer: No. Both can shut down sperm production, because injected testosterone tells your brain to turn down the hormone signals your testicles need to make sperm. The AUA/ASRM male-infertility guideline says testosterone monotherapy should not be prescribed to men interested in current or future fertility. Current labels warn that reduced fertility can occur and may be irreversible.

Why it happens

Your brain sends two signals to your testicles: LH (luteinizing hormone), which drives testosterone production, and FSH (follicle-stimulating hormone), which drives sperm production. Testosterone from a shot makes the brain dial both down. Less FSH means less sperm, whichever ester is in the vial.

The Xyosted and Azmiro labels say reduced fertility is seen in some men on testosterone, and that the effect on fertility "may be irreversible."

If kids are in your plans

  • See a urologist or reproductive urologist before starting or switching. The AUA/ASRM guideline says testosterone monotherapy should not be prescribed to men interested in current or future fertility.
  • Other options exist, but they aren't TRT. Clinicians may use hCG, clomiphene or similar medicines for men with low testosterone who want to protect fertility. They work differently, carry their own risks, and aren't interchangeable with testosterone. Clomiphene is used off-label in men, and enclomiphene isn't FDA-approved. None comes with a fertility guarantee. See our guides to clomiphene providers and enclomiphene providers.
  • Already on testosterone and want children? Don't stop or change anything on your own. Ask for a referral first.

Do you actually have low testosterone, and who should see a specialist first?

Short answer: Every FDA label for these products says to confirm low testosterone with morning blood tests on at least two separate days before starting. Guidelines add that you need symptoms or signs that fit, too. No single number, quiz or online calculator diagnoses you, and some men should see a specialist before anything else.

What the labels and guidelines ask for

  • The labels: total testosterone measured in the morning, on at least two separate days, below the normal range.
  • The American Urological Association: two early-morning total testosterone tests, with below 300 ng/dL as a reasonable cutoff, alongside symptoms or signs of low testosterone.
  • The Endocrine Society: symptoms and signs that fit, plus levels that are clearly and consistently low.

Total testosterone is all the testosterone in your blood, measured in nanograms per deciliter (ng/dL). A lab's "normal range" and your symptoms both matter. One reading doesn't settle it.

See a specialist first if…

  • You're trying to conceive, or you've had trouble conceiving (urology or reproductive urology).
  • Your testosterone is very low, or you have headaches or vision changes that could point to a pituitary problem (endocrinology).
  • You have or have had prostate or breast cancer (urology or oncology).
  • Your hematocrit is already high.
  • You have untreated, severe sleep apnea.
  • You've had a heart attack or stroke in the last three to six months. The AUA advises waiting.
  • Your blood pressure isn't controlled. The labels say testosterone isn't recommended.

Not sure where you fall: local doctor, specialist, or online program?

Map the care route that fits you. Find My TRT Path turns your situation into a care route and a list of questions to ask before you pay. It's educational. It doesn't diagnose you or decide eligibility.

Map my TRT care route

Short answer: Yes, when a properly licensed clinician issues a valid prescription and the prescribing and dispensing comply with federal and state law. Testosterone is a Schedule III controlled substance. Federal DEA/HHS telemedicine flexibilities currently allow DEA-registered practitioners to prescribe Schedule II–V controlled medications by telemedicine without a prior in-person medical evaluation when the federal conditions are met, through December 31, 2026. States and individual care programs can impose additional requirements.

Schedule III means testosterone is controlled under federal law because of abuse and dependence risk. A website offering prescription testosterone without a valid prescription is not an alternative care route.

Where the federal rule stands

DEA and HHS extended the COVID-era telemedicine flexibilities through December 31, 2026. A permanent special-registration framework was still under federal review when this page was checked in September 2026. Because the rule can change, re-check the current federal rule and your state's requirements before relying on telemedicine for future refills.

Male Excel's own site, for example, says an in-person medical exam may be required depending on DEA and state law.

Red flags that should stop you cold

  • A seller offers prescription testosterone without a valid prescription.
  • There is no identifiable licensed prescriber or dispensing pharmacy.
  • The site tells you blood work or a clinical evaluation is unnecessary.
  • The product is presented as "research use only" while being sold for human TRT.
  • The seller will not tell you what drug, strength, pharmacy or formulation you will receive.

Ask any online program: "If federal telemedicine rules change after December 31, 2026, what happens to my refills?"

If you've cleared the fertility and diagnosis questions and you want care online, compare what each program actually publishes before paying.

Which ester do online TRT programs use, and is it FDA-approved?

Short answer: The two current commercial partners we checked, Male Excel and Taurus Meds, publicly name testosterone cypionate and describe compounded care. Compounded drugs are not FDA-approved. If you specifically need an FDA-approved cypionate vial, generic enanthate, Xyosted, insurance coverage, or your own retail pharmacy, a local prescriber/pharmacy route may fit the formulation question better.

FDA-approved vs compounded, in plain words

FDA-approved means FDA reviewed a manufacturer's specific drug product for safety, effectiveness and quality and approved its labeling. An FDA-approved generic must meet FDA requirements for the approved reference product.

Compounded means a pharmacy or other permitted compounder makes a preparation for a medical need under compounding law. FDA does not approve compounded drugs or review each compounded preparation for safety, effectiveness or quality before marketing. Compounded drugs can serve an important patient need, but they are not generics and should not be described as FDA-approved, safer or more natural.

The oil can be a clue, not proof by itself. The FDA-approved cypionate labels we reviewed use cottonseed oil. Male Excel publicly lists a cypionate formula using grapeseed oil by default, with cottonseed available on request, and its site describes its prescriptions as compounded. If the approval status matters to you, verify the manufacturer/NDC or ask the dispensing pharmacy directly rather than relying on the oil alone.

Affiliate disclosure. TRT Provider Guide has affiliate relationships with Male Excel and Taurus Meds. If you use a qualifying partner link, we may earn a commission. That does not change what we report, and a local prescriber plus retail pharmacy is the better route when the reader needs a specific FDA-approved product or insurance coverage.

Provider facts checked on official company pages 20 September 2026. Prices are provider-stated and can change. We did not enroll or inspect a patient-specific checkout.

Male Excel: the clearer partner fit if you want compounded cypionate

Best for: a reader with a confirmed clinical reason for testosterone treatment who is comfortable with compounded cypionate and wants one online program to manage testing, prescribing and ongoing follow-up.

Not for: someone specifically seeking enanthate, Xyosted, an FDA-approved cypionate vial, insurance payment for the medication, or a prescription sent to a retail pharmacy.

What we verified on Male Excel's pages:

  • It publicly offers testosterone cypionate injections and testosterone cream.
  • Its injection page lists 200 mg/mL testosterone cypionate with benzyl benzoate, benzyl alcohol and grapeseed oil, with cottonseed available on request.
  • Its current pricing page lists a $99 consultation, a required $99/month medical membership, and injectable treatment starting at $120/month, billed as a 60-day supply, plus shipping and handling.
  • Its FAQ says its medical providers prescribe in every state except Alabama, Alaska, Arkansas, Connecticut, Hawaii, Idaho, Louisiana, Minnesota, Mississippi, New Hampshire and Rhode Island.
  • Its site says an in-person medical exam may be required depending on DEA and state law.

The honest trade-off. Male Excel does not publicly offer enanthate or Xyosted, and its published cypionate formula is compounded rather than an FDA-approved retail vial. If either ester is acceptable and you mainly want a managed compounded-cypionate program, it is relevant. If the exact FDA-approved formulation, insurance, or enanthate is the reason you searched, use a local prescriber/pharmacy route instead.

If compounded cypionate fits the route you already chose: review Male Excel's current pricing and state availability, then confirm the exact medication and pharmacy before paying.

Review Male Excel's current TRT pricing

A prescription is not guaranteed. A licensed clinician must decide whether treatment is appropriate.

Taurus Meds: lower advertised treatment price, but resolve the fee conflict first

Best for: a budget-focused reader who is comfortable with a compounded cypionate program and is willing to get the full recurring charges in writing before enrolling.

Not for: someone who needs enanthate, Xyosted, an FDA-approved retail vial, or a clean complete-cost quote from the public page alone.

What we verified on Taurus's pages:

  • The current offer names testosterone cypionate and says the medications are compounded in the U.S.
  • The offer advertises $49 for blood work and consultation and $149/month for doctor-prescribed medication if approved.
  • The offer says there are no membership fees.
  • Taurus's current Terms of Service separately state a $17.99 recurring membership fee per billing period. Because those public statements conflict, we do not publish a "complete first-year cost" until Taurus clarifies which charge applies to this offer.
  • The public offer does not identify the carrier oil.

Price-first and comfortable with compounded cypionate? Read the current Taurus offer, then ask support to confirm the ester, carrier oil, pharmacy, cancellation terms and all recurring fees in writing before paying.

Review Taurus Meds' current $49 offer

If you want an FDA-approved vial, enanthate, Xyosted or insurance

Start with a clinician who can prescribe the exact FDA-approved product to a retail/specialty pharmacy if it is appropriate for you. That route is usually a better fit for a formulation-specific search because the medication choice, manufacturer, pharmacy stock and insurance coverage stay visible rather than being bundled inside a compounded program.

Six questions to get answered in writing before you pay

  1. Which drug and formulation will I receive: cypionate, enanthate, Xyosted, or something else?
  2. Is the exact product FDA-approved or compounded, and which pharmacy will dispense it?
  3. What oil and inactive ingredients are in it?
  4. Can the prescription go to my own pharmacy if the prescribed product or insurance requires that?
  5. What diagnostic and follow-up blood testing does the clinician require, and what is included in the price?
  6. What happens to my refills if federal or state telemedicine rules change?

A portal message or email gives you something concrete to compare with the final prescription and bill.

Testosterone cypionate vs enanthate: 8 claims you'll read online, checked

Short answer: The biggest errors are treating all enanthate products as one thing, turning rough half-life estimates into prescribing rules, and comparing prices for different package sizes. The current labels support a much simpler conclusion: compare the exact product, formulation, route, inactive ingredients and cost rather than assuming the ester alone decides the outcome.

Claim What the best source supports What it means for you
"You can always swap cypionate and enanthate 1:1." Azmiro's current FDA label warns that injectable testosterone products may differ in dose, strength or instructions and are not substitutable milligram‑for‑milligram. A switch belongs on a new prescription and monitoring plan.
"Enanthate is safer." The often‑cited 2022 study compared IM cypionate with a subcutaneous enanthate autoinjector; route and device changed too. It cannot isolate an ester‑only safety advantage.
"Neither FDA label publishes a half‑life." Reviewed cypionate labels state about 8 days after IM injection; the reviewed generic enanthate vial labels do not state one. Treat internet ester‑half‑life charts as secondary estimates, not prescribing instructions.
"Cypionate is more anabolic; enanthate is better for libido." We found no good head‑to‑head evidence supporting ester‑specific outcome claims like these. Do not choose a prescription ester for unsupported performance or symptom promises.
"Any cypionate oil is basically the same FDA‑approved product." The FDA‑approved cypionate labels reviewed use cottonseed oil; compounded products can use different vehicles. Check the actual manufacturer/pharmacy and label, not just the ester name.
"Enanthate cannot be used under the skin." Xyosted is FDA‑approved testosterone enanthate for subcutaneous administration. Route depends on the specific product, not merely the ester.
"The cheaper vial is always the cheaper drug." Vial sizes differ; cost per equal amount of drug can reverse the headline‑price impression. Compare the same concentration and amount.
"Compounded testosterone is an FDA‑approved generic." FDA states compounded drugs are not FDA‑approved and are not the same as FDA‑approved generics. Ask why compounding is being used and which pharmacy makes the preparation.

Checked 20 September 2026 against current FDA/DailyMed labeling, FDA compounding guidance, the 2022 Journal of Urology study and current federal guidance.

How we built this comparison

Short answer: We read the FDA label for every U.S. cypionate and enanthate product, counted labels on DailyMed, checked current cash prices on Drugs.com's price guide and converted them to price per 100 mg for a like-for-like comparison. We keep verified facts, company claims and our own judgment separate.

  • Labels: Depo-Testosterone, a generic cypionate, Azmiro, both enanthate vials and Xyosted, read on DailyMed and Drugs@FDA.
  • Supply: DailyMed searches by drug code for each 200 mg/mL vial, plus the ASHP shortage listing.
  • Prices: Drugs.com's current price guide for a like-for-like cash-price snapshot. We use dated price examples because pharmacy prices change.
  • Rules and guidelines: FDA and HHS labeling notices, the Federal Register, and AUA, AUA/ASRM and Endocrine Society guidelines.
  • Programs: Male Excel's pricing/FAQ/formula pages and Taurus Meds' offer/terms pages. We report provider-stated facts as such. We didn't sign up or test products.
  • What we didn't do: clinically review this page, examine anyone, or collect health data.

Our full method, How We Review TRT Providers, separates verified facts, provider-stated facts, customer-experience signals and editorial conclusions, and it calculates complete cost rather than repeating a teaser price. We don't assign numeric scores.

Frequently asked questions

Is testosterone enanthate stronger than cypionate?

Only slightly, by weight. Enanthate carries about 72 mg of testosterone per 100 mg of drug, versus about 70 mg for cypionate, roughly 3% more. That molecular-weight difference is real, but it does not prove better clinical outcomes for one ester. The prescribed product and monitoring plan matter more than declaring one ester "stronger."

What's the half-life of testosterone enanthate vs cypionate?

The cypionate labels say about eight days after an injection into the muscle. The enanthate vial labels don't print a half-life. Figures online range from 4.5 to 12 days depending on the source, so treat them as rough estimates. The prescribed product, route, interval and individual response all shape blood levels, so a half-life estimate should not be used to change a schedule on your own.

Can I switch from cypionate to enanthate at the same dose?

Don't assume you can. A current FDA label says injectable testosterone products aren't substitutable milligram for milligram. Your prescriber should write a new prescription with the dose and schedule for the new product, and your blood work should be rechecked afterward.

Which one hurts less to inject?

No study has compared the two FDA-approved vials for pain. They use different oils (cottonseed for cypionate, sesame for enanthate) and different preservatives, and people report reactions in both directions. If a new product hurts more, bring both labels to your prescriber.

Which one contains sesame oil?

FDA-approved enanthate: the 5 mL vial and the Xyosted pen. Xyosted's label lists sesame oil allergy as a reason not to use it. FDA-approved cypionate uses cottonseed oil instead. Compounded products vary, so ask the pharmacy what's in yours.

Is testosterone enanthate FDA-approved?

Yes. Two companies, Hikma and Eugia, make an FDA-approved generic 5 mL vial, and Xyosted is an FDA-approved enanthate pen. Compounded enanthate made by a pharmacy isn't FDA-approved.

Is Xyosted the same as testosterone enanthate?

It's the same drug in a different product. Xyosted is a weekly, single-dose, preservative-free pen used under the skin of the belly, in three strengths, with its own label and trial data. The generic enanthate vial goes into the muscle every two to four weeks, per its label.

Why does testosterone enanthate cost more?

Fewer companies make it (two, versus many for cypionate), it comes in only one vial size, and pharmacies pay more for it. Medicaid's pharmacy-cost survey put Hikma's enanthate at roughly four times the cost per milligram of Hikma's own cypionate.

Does insurance cover testosterone cypionate or enanthate?

Some plans cover the FDA-approved generics, often after prior authorization showing repeat low morning testosterone and symptoms. Xyosted is brand-only and usually needs your plan's approval. Compounded testosterone generally isn't covered. Check your plan's formulary.

Is there still a testosterone cypionate shortage in 2026?

Yes. ASHP still listed testosterone cypionate injection as a shortage when we checked in September 2026, with Pfizer's Depo-Testosterone on back order and some generic makers reporting supply. Availability depends on your pharmacy, so call ahead before your refill.

Do online TRT clinics use cypionate or enanthate?

The two current partner programs checked here, Male Excel and Taurus Meds, publicly name testosterone cypionate and describe compounded care. Neither public page we reviewed lists enanthate. Ask any program in writing which exact drug, carrier oil and dispensing pharmacy you will get.

Is compounded testosterone the same as the pharmacy version?

No. Compounded testosterone is mixed by a pharmacy and isn't FDA-approved, so it hasn't gone through FDA review for safety, effectiveness or quality. That doesn't make it fake or illegal, but it isn't a generic, and it isn't "safer" or "more natural." The AUA says commercially made testosterone should be prescribed when possible.

Does either one protect fertility better?

No proven fertility advantage belongs to either ester. Exogenous testosterone can suppress sperm production, and current labeling warns reduced fertility may be irreversible. The AUA/ASRM guideline says testosterone monotherapy should not be prescribed to men interested in current or future fertility; discuss family-building plans with a urologist or reproductive urologist before treatment.

Which is better for hematocrit or estrogen?

There's no good evidence that the ester itself matters. The study most often cited compared cypionate injected into the muscle with an enanthate pen under the skin, so the route and device changed too. If hematocrit or estradiol is a concern, ask your prescriber about route and dosing interval.

Is testosterone a controlled substance, and can I get it online legally?

Yes, it's Schedule III, and you need a valid prescription. Federal DEA/HHS flexibilities allow DEA-registered practitioners to prescribe Schedule II–V controlled medications by telemedicine without a prior in-person exam when the federal conditions are met, through December 31, 2026. States can be stricter, and some programs require an in-person exam.

What do "test cyp" and "test E" mean?

They're slang for testosterone cypionate and testosterone enanthate. You'll also see "TC vs TE" and the reversed search "testosterone enanthate vs cypionate." It's all the same comparison.

My vial says 250 mg/mL. Is that normal?

Not for an FDA-approved product. The FDA-approved cypionate and enanthate vials we found come in 100 or 200 mg/mL. A 250 mg/mL label points to a compounded, foreign or unregulated product. Don't use it until a pharmacist or prescriber confirms exactly what it is and where it came from.

Can one low testosterone test tell me I need TRT?

No. The FDA labels call for morning tests on at least two separate days, and guidelines also require symptoms or signs that fit. One number doesn't diagnose you.
