Energize Testosterone and Wellness Reviews: What 119 Testimonials and the Public Record Show
This page is about Energize Testosterone & Wellness Center in O'Fallon, Missouri (energize-wellness.com) — not Energize Health and Wellness in Fort Mill, South Carolina, and not testosterone-booster supplements.
Energize Testosterone and Wellness reviews look close to perfect: 4.98 out of 5 from 119 testimonials on the clinic's own website. But we read all 119, and only 4 talk about testosterone treatment. Its site names nurse practitioner Jennifer McElfresh, posts no TRT prices, and her Missouri license was censured in 2017.
That last part sounds worse than it may be. It also isn't nothing. Here's what we found, what it means, and the exact questions to ask before you pay.
Energize may fit you if you live near O'Fallon, you want face-to-face care, and you want a clinician to sit down and walk you through your labs.
Look somewhere else first if you need published prices, insurance billing confirmed up front, a fertility-first plan, or a prescriber with a spotless public record.

Is Energize Testosterone & Wellness the right clinic for you?
Energize may suit men near O'Fallon who want the unhurried, in-person care and detailed lab explanations described in its reviews. It's a weaker fit if you need published prices, confirmed insurance, a fertility-first plan or flexible hours. Its founder's 2017 Missouri discipline is a fact you should weigh before booking.
Maybe you're close by. A friend recommended "Jen." Or a clinic listing showed up with near-perfect stars. Or the consult is already booked and you want to know what you're walking into.
Good. That's the right instinct. Here's the honest sort.
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 as an educational starting point, and take the questions on this page to a clinician before you pay. It's educational and non-diagnostic — it doesn't diagnose low testosterone or decide whether you'll get a prescription. Privacy policy.
What do Energize Testosterone and Wellness reviews actually say?
Reviews praise the staff's warmth, the time spent with patients and clear explanations of blood work. Most of the displayed review volume comes from collections the clinic or its website vendor runs; about half of its 119 testimonials use recurring displayed names, and only 4 describe testosterone treatment. The directory snapshots are small and mostly positive.
Every review source, side by side
Different sites show different numbers. Here's each one, where the displayed reviews come from, and how much weight it deserves.
We could not establish when each directory copied its figures, and some posts overlap across sites. What's consistent: the reproduced listings are small, with 6 to 15 reviews in each snapshot. The big numbers come from the clinic's own review system. Don't add or average these collections.
That's normal for a small practice. Many offices ask patients for a review after each visit. It just means the 4.98 is a mood, not a grade.
What 119 testimonials are really about
We read every dated testimonial on Energize's website — October 2023 through March 2026 — and sorted each one by what it actually talks about.
How we counted: We used all 119 dated posts, normalized capitalization and extra spaces in displayed names, and excluded three undated promotional cards. We counted explicit mentions; we did not infer a treatment or gender from a name. Topics can overlap, so the rows are not meant to add to 119. The final content row excludes every post with a named treatment, lab detail or specific price/fee comment. Generic value praise does not count as a specific fee comment. The 12-month window starts October 20, 2025.
What this tells you: patients like being there. They feel heard. They don't feel rushed. That's real, and it matters more than people admit.
What it doesn't tell you: whether TRT will work for you, what your full bill will be or how the clinic handles problems as a rule. Recurring names do not tell us why someone posted again. We found no evidence the reviews are fake. Most just aren't about testosterone.
What men say about TRT at Energize specifically
The testosterone-focused reviews and the lab comments line up on a few points:
- Close monitoring. One patient wrote that the clinic regularly checks his labs and adjusts his dose as needed (Cory A., April 9, 2025, Energize website).
- Straight pricing compared with a prior clinic. "No hidden fees, like the places I went to before." — Douglas E., December 31, 2023, Energize website.
- Labs explained line by line. Two reviewers specifically praise blood-result explanations (Charles H., October 9, 2025, and Megan S., May 6, 2025, Energize website).
- Labs drawn nearby, with little waiting, per Kenton P.'s October 16, 2025 review on Energize's website.
On Tebra, one patient summed up the tone most people describe: "Never feel judged and comfortable asking questions and talking to the whole staff!" — Michael W., February 4, 2026.
These are individual experiences shared on review platforms. They aren't proof that treatment works, that results are typical, or that any policy is still current.
The complaints we found
We looked for negatives on purpose. Here's everything material:
- A lab mix-up. A review by Randy Grommet reproduced on the TRT Index directory says the blood-draw site had no record of the appointment, the patient couldn't get the lab paperwork, and the office was closed on a day it was listed as open. The directory shows a relative date, not a verified posting date. We couldn't see whether the clinic replied. It's one report, not a proven pattern — but it's a good reason to confirm your lab order and appointment before you fast and take time off work.
- An employment dispute. A 1-star review by Brianca Palozola reproduced on Birdeye says the writer is the parent of a former employee, alleges a final-paycheck dispute and says customers were overcharged for products. It's secondhand, it isn't from a patient, and we couldn't verify the allegations or outcome.
- Conflicting listings. Directories disagree on the clinic's address and phone. More on that below.
We found 0 complaints displayed on the clinic's BBB complaints page.
Who will treat you at Energize — and is it legit?
BBB lists Energize as a Missouri LLC started in 2023; the clinic names nurse practitioner Jennifer McElfresh as its founder, and her federal NPI record lists a Missouri license. Public records show her Missouri nursing license was censured in 2017 over unauthorized prescriptions. We could not confirm her current license status, so check it yourself before booking.
Her record, step by step
Quick translation: an NPI is a federal ID number used in health care billing and other standard transactions. It helps match records to a provider. It does not prove their license is current. CMS says so itself.
The 2017 discipline, in plain English
Here's what the official records say, and nothing more.
Missouri's Board of Nursing listed a censure dated November 4, 2017, for Jennifer Michelle McElfresh, under the license number that appears on her NPI record. A censure is a formal public reprimand. It is not a suspension or a revocation.
In its January 2018 enforcement report, Illinois's licensing department reported that it placed her Illinois nursing license in refuse-to-renew status. Its stated reason: her Missouri license had been disciplined for writing and signing unauthorized prescriptions.
What that means for you:
- It's about prescribing authority. In Missouri, a nurse practitioner prescribes under a written agreement with a physician that spells out what she may prescribe. The 2017 issue, as the records describe it, was prescriptions outside that authorization.
- It's almost nine years old. We didn't see the full board order or confirm later actions or her current status. The summaries we read don't tell you how it was resolved. The reported events predate Energize's listed 2023 start; they are not a finding about its current TRT care.
- It's directly relevant to TRT. Testosterone is a Schedule III controlled substance — a drug federal law tracks closely because it can be misused. Prescribing it depends on exactly the kind of authorization the 2017 records describe.
Our take: For some readers, this ends it. That's a fair line to draw, and the options below are built for you. For others, a reprimand from 2017 matters less than how she practices today. If that's you, do two things before you book: look up her current Missouri license, and ask at the consult who her collaborating physician is and whether her controlled-substance authority is current. A good clinic answers both without blinking.
Can a nurse practitioner prescribe testosterone in Missouri?
Yes, with conditions. In Missouri, an advanced practice registered nurse (APRN) generally works under a written collaborative practice arrangement with a physician. That agreement can give the NP authority to prescribe Schedule III drugs like testosterone. The NP also needs a Missouri Board of Nursing controlled-substance prescriptive-authority certificate, Missouri Bureau of Narcotics and Dangerous Drugs (BNDD) registration and federal Drug Enforcement Administration (DEA) registration. And the collaborating physician must regularly review a share of the NP's charts, including ones where controlled substances were prescribed.
So "it's just a nurse" isn't the right worry. A qualified NP can lawfully prescribe testosterone when those requirements are met. The right question is: who is the physician behind the agreement, and is everything current? Energize's website doesn't name a collaborating physician. Ask. The requirements are set out in Missouri's collaboration law, its prescriptive-authority law and BNDD's APRN instructions.
Is Energize a med spa or a medical clinic?
Both. Energize offers testosterone therapy, menopause hormone therapy, erectile dysfunction (ED) treatment, semaglutide weight loss, IV vitamin drips, Botox, dermal fillers and lash services. Nothing wrong with that. Just know you're choosing a broad wellness practice, not a men's-health-only clinic.
→ Start with the Missouri Board of Nursing's license-verification instructions. Match Jennifer Michelle McElfresh and Missouri license number 2005023515; ask the clinic to document current APRN and controlled-substance authority too. Then read how to verify any TRT provider's license for what each status means.
How much does Energize Testosterone and Wellness cost?
We found no published TRT prices on the clinic pages checked. Its location-page data says "Free Confidential Consultation," but we could not confirm that this covers an initial men's TRT visit. Ask for a written first-year quote that separates labs, visits, medication, supplies and any recurring fee.
Here's the honest version.
Energize does not publish a TRT price list on the pages we checked. If seeing the full cost before you walk in is a must, ask the office for a written quote first; if it cannot provide one, compare the published price breakdowns below. At an in-person consultation, you can ask for a face-to-face quote and every follow-up answer in one sitting. A checkout page can't do that.
Reviewers who mention money say Energize's prices are fair and that they hit no surprise fees. The two price-praise posts use the same displayed name, Lourdes L., as a later post that calls it a friend's business. That's useful context. It still isn't a quote.
What's published vs. what you need to ask
Does Energize take insurance?
The clinic doesn't say. Healthgrades lists Cigna plans for McElfresh, and an older review reproduced on TRT Index says insurance covered the reviewer's labs. We could not confirm that the directory's plan list applies to TRT at Energize today. Neither is a coverage policy. Ask Energize whether it bills your plan for visits, and ask your insurer separately about the labs and the exact testosterone product. Those three can come out differently. Our guide to TRT providers that take insurance explains how.
Your first-year cost worksheet
A monthly number can hide half the bill. Ask Energize to fill in every line, and mark anything already included so you don't count it twice.
Two rules that keep the math honest:
- Unknown is not zero. If they can't price a line, leave it blank and ask again.
- Keep exit costs separate. Cancellation fees, unused medication and records fees go in a different column, not your normal-year total.
For context, here's how two online programs publish their starting math (provider-published prices, not quotes):
- Male Excel: $99 consultation and at-home test, then a required $99 a month membership. Its advertised injection package starts at $120 a month for testosterone cypionate with thyroid medication and supplies, billed every other month for a 60-day supply. Twelve months at those advertised rates comes to $2,727: $99 + 12 × ($99 + $120), before shipping and extras. That is a rate-model subtotal, not a testosterone-only quote or a verified full-year bill; ask for your actual prescription costs and charge dates. Male Excel's price breakdown.
- Hone Health: $45 first test for Plus or $65 for Premium, then $135 or $155 a month, respectively. Testosterone cypionate starts at $28 per vial, billed separately. Using the plan pages' paid confirmation-test prices, initial and confirmation testing plus 12 membership payments runs $1,710–$1,745 for Plus or $1,950 for Premium, before medication. Plus assumes a $45–$80 confirmation test; Premium assumes $25. Hone's pages disagree about confirmation charges, so confirm which applies before paying. Plus pricing, Premium pricing, lab schedule and retest policy.
Ask each provider to name the exact injection product, its FDA-approved or compounded status, and the dispensing pharmacy. Thyroid medication is a separate treatment; ask why it is included in any proposed plan.

What happens at Energize, from consult to treatment?
Energize says care starts with an evaluation and a "nine-panel" blood test, then a personalized plan that often uses testosterone injections. It sends patients a symptom questionnaire every two months. Appointments run Tuesday, Thursday and Friday by confirmation only, closed for lunch from noon to 1.
Here's the process as the clinic describes it. These are Energize's statements, not things we watched happen.
- Consultation. Confirm whether the visit is free for men's TRT and what it includes.
- Blood work. Energize calls it an "initial nine-panel blood test" and says it's critical, because low-T symptoms can have other causes. It doesn't list the nine tests.
- Results review. Reviewers describe the NP going over their labs with them. This is one of the specific care details they praise.
- Treatment plan. The clinic says plans "often" involve testosterone injections.
- Follow-up. A symptom questionnaire every two months. Energize says it monitors levels, but it doesn't publish a lab schedule.
What the clinic doesn't say: how many blood tests it needs before starting, whether you inject at home or come in, how refills work, whether any follow-ups can happen by video, or what happens if you want to stop. Those are on the question list below.
One logistics note. Energize advertises TRT at its O'Fallon office but does not publish a complete online TRT process or a list of states served. Its ED service is different: it says you can start with an online medical form and get medication shipped. Don't assume the same applies to testosterone. Ask whether any TRT visits can happen by video and whether the clinician can treat you in the state where you will be during the visit.
What about refills, cancellation, refunds and records?
We found no public TRT-specific terms for refill timing, response times between visits, minimum commitments, automatic renewal, cancellation, refunds or medical-record access. The site's cosmetic consent forms do not establish those rules for TRT. Before paying, ask when refills are requested and sent, how to reach the prescribing team, what notice ends future charges, whether any fees or medication payments are refundable, and how to get your records, including any fee. If you leave, ask the clinician how to hand care over to your next provider.
Before your first visit, read what to expect at a first TRT appointment and how to prepare for a testosterone blood test.
What testosterone does Energize prescribe — "bioidentical," FDA-approved or compounded?
Energize describes "bioidentical" testosterone and says plans often involve injections. That word doesn't tell you whether a product is FDA-approved or compounded — prescription testosterone of both kinds is made in labs. Ask for the exact product name, whether it's FDA-approved, and which pharmacy fills it.
Energize's TRT page says its bioidentical testosterone comes from natural sources and is structurally identical to the testosterone your body makes, "unlike synthetic hormones."
Here's what that misses.
- "Bioidentical" isn't an approval category. An FDA-commissioned review of compounded bioidentical hormone therapy, including testosterone, found a lack of rigorous evidence of safety and effectiveness.
- FDA-approved testosterone exists. Testosterone cypionate injection, for example, is sold as FDA-approved products. An FDA-approved drug was reviewed for safety, effectiveness and manufacturing quality before it was sold.
- Compounded testosterone is different. A compounder prepares it. Compounded drugs are not FDA-approved, and the FDA doesn't review them for safety, effectiveness or quality before they're sold. Compounded isn't automatically bad. It just isn't the same thing, and calling it "bioidentical" doesn't establish that it's safer or "more natural."
Clomiphene is FDA-approved for certain ovulation problems in women; its use in men is off-label, meaning outside the approved use. Enclomiphene is not FDA-approved; its presence on the FDA's 2026 compounding evaluation list is not approval. Some hCG products, including Pregnyl, are approved for selected cases of male hypogonadotropic hypogonadism — low testosterone caused by deficient hormonal signals. That is not approval for every male fertility use or for adding hCG to TRT.
We could not find out which kind Energize prescribes, or which pharmacy fills it. Neither is on its website.
So ask three things: the exact product name, whether that product is FDA-approved or compounded, and the dispensing pharmacy. If you want FDA-approved only, say so up front. Our list of FDA-approved testosterone products shows what to listen for.
Will Energize start TRT if your testosterone is "normal"?
Energize's site says "Normal is NOT Optimal" and talks about keeping levels in an "optimal range." Medical guidelines are stricter: low testosterone is diagnosed from symptoms or signs plus consistently low results on repeat early-morning tests. Ask Energize exactly how it decides who qualifies.
That tagline is the right thing to ask about. Not because it proves anything. Because the answer tells you how the clinic thinks.
Here's the medical standard for adult men:
- Symptoms or signs that fit low testosterone, like low sex drive, ED, fatigue or loss of muscle. These overlap with lots of other problems — Energize says so itself.
- Consistently low testosterone on reliable tests. In July 2026, the Endocrine Society said this means at least two early-morning, fasting tests.
- A look for the cause. Low testosterone can come from the testicles or from the pituitary gland, and that changes the plan.
Total testosterone is all the testosterone in your blood. Free testosterone is the small share not attached to proteins. Neither number alone makes a diagnosis. And no single cutoff — including the often-quoted 300 ng/dL — is a diagnosis by itself.
About the benefits list. Energize's site lists more energy, lean muscle, memory and thinking, sleep, mood, less belly fat, focus and sex drive. Evidence is stronger for some of those than others. In the large Testosterone Trials of older men with low testosterone, sexual function improved modestly, while the cognitive trial found no significant improvement in memory or thinking in men with age-associated memory impairment. Results vary, and no clinic can promise them.
Ask this, word for word: "If my two morning tests come back in the normal range, would you still prescribe testosterone?" Ask the clinician to explain how that fits the diagnostic guidance above.
More here: how low testosterone is diagnosed and do you need two low tests for TRT.
What about fertility, safety and seeing a specialist first?
Testosterone therapy can lower sperm production, and Energize's website doesn't say how it handles fertility. If you might want children, raise it first or start with a urologist. Men with certain health histories should see a specialist before any TRT clinic.
Fertility. Testosterone you take as medicine can tell your body to make less of its own — and less sperm. That's called suppressed spermatogenesis (sperm production). It doesn't happen the same way to everyone. Nobody can promise you'll become infertile, stay fertile or recover on a schedule. If kids are part of your plans in the next few years, a urologist or reproductive urologist is the better first stop. Clomiphene, enclomiphene and hCG sometimes come up here. They are not TRT and they don't guarantee anything. The AUA/ASRM male-infertility guideline advises against testosterone alone for men interested in current or future fertility. See TRT and fertility.
See a specialist first if you have:
- A history of prostate or breast cancer
- Elevated hematocrit (the share of your blood made of red cells)
- Untreated severe sleep apnea
- A recent heart attack, stroke or other major heart event
- Symptoms that point to a pituitary or testicle problem
- Lab results that are unusual, not just borderline
Monitoring to expect anywhere. Testosterone can raise hematocrit and blood pressure. The FDA added blood pressure warnings to testosterone labels in 2025. Any good clinic should check those before and during treatment, review testosterone levels and symptoms, and assess prostate health as it fits your age and history. That can include discussing PSA, a blood marker used in prostate assessment. The Endocrine Society guideline sets out the baseline and follow-up checks. Ask Energize for its lab schedule in writing — a questionnaire isn't a lab plan.
Urgent symptoms. Call 911 for chest pain or trouble breathing. A new swollen, painful leg needs urgent medical assessment for a possible blood clot. Don't wait for a routine clinic appointment. CDC blood-clot symptoms.
Energize vs. other TRT options in O'Fallon and online
Energize is one of several testosterone clinics in O'Fallon and offers TRT inside a broader wellness practice. Online programs like Male Excel and Hone Health publish prices and list Missouri, but testing and visit arrangements differ: Male Excel starts with an at-home test, while Hone offers at-home or lab-based testing depending on the plan.

One note on online care: a federal rule currently lets qualified clinicians prescribe controlled substances like testosterone over live video without a prior in-person visit. That temporary rule runs through December 31, 2026. State rules and clinical judgment still apply. It's a reason to plan, not a reason to rush. See online vs. local TRT care.

Frequently asked questions
The key checks are current prescribing authority, a written full-cost quote and a proper low-testosterone evaluation. The answers below separate what the clinic publishes from what remains to ask before you book.
Is Energize Testosterone & Wellness legit?
BBB lists it as a Missouri LLC started in 2023. The clinic names nurse practitioner Jennifer McElfresh as its founder, and her federal NPI record lists a Missouri license. Public records show her Missouri license was censured in 2017 over unauthorized prescriptions. Start with the Missouri Board of Nursing's verification instructions and confirm current prescribing authority before booking.
Are Energize's reviews real?
We found no evidence they're fake. Most of the displayed review volume comes from systems the clinic or its website vendor runs. On its own site, 61 of 119 posts use recurring displayed names, and only 4 mention testosterone treatment.
How much does testosterone therapy cost at Energize?
We found no published TRT prices on the clinic pages checked. Its location-page data mentions a free confidential consultation, but men's TRT terms were not confirmed. Ask for a written first-year quote that covers labs, visits, medication, supplies and any membership.
Does Energize take insurance?
The clinic doesn't say online. Ask whether it bills your plan for visits, and check labs and medication with your insurer separately.
Who is the provider at Energize?
The clinic names Jennifer McElfresh, MSN, APN-BC, a nurse practitioner and its founder. These credentials are clinic-stated; she's the only clinician named on its own website. Tebra's practice page also lists Andrew Brown, MD, so confirm who will evaluate and prescribe for you.
Can a nurse practitioner prescribe testosterone in Missouri?
Yes, under a written collaborative practice arrangement with a physician that allows Schedule III prescribing, plus a Missouri Board of Nursing controlled-substance prescriptive-authority certificate and state BNDD and federal DEA registrations. Ask Energize who its collaborating physician is.
What was the 2017 discipline about?
Illinois's licensing department reported that her Missouri license was disciplined for writing and signing unauthorized prescriptions. Missouri's board listed a censure, a formal public reprimand, dated November 4, 2017. We didn't see the full order or her current status.
Does Energize offer online TRT?
It advertises TRT at its O'Fallon office but does not publish a complete online TRT process or state-coverage list. Its ED service can start with an online form and ship medication. Ask whether any TRT follow-ups can happen by video.
What kind of testosterone does Energize use?
It describes "bioidentical" testosterone and says plans often involve injections. It doesn't say whether the product is FDA-approved or compounded, or which pharmacy fills it. Ask before you start.
Do I need two blood tests before starting TRT?
The Endocrine Society calls for symptoms or signs plus consistently low testosterone, confirmed with at least two early-morning, fasting tests. Ask how many Energize requires.
Will TRT affect my fertility?
It can lower sperm production. If you might want children, raise it at your first visit or see a urologist first.
Where is Energize located?
199 Frontier Park Drive, O'Fallon, MO 63366, per its website. Many older listings show State Highway K. Confirm when you book.
What are Energize's hours?
Tuesday, Thursday and Friday by confirmed appointment, closed for lunch from noon to 1, per its website.
Does Energize treat women?
