TRT and cholesterol, the short answer: at replacement doses, testosterone usually causes small or variable lipid changes rather than making the whole cholesterol panel worse. Older trials often found a small HDL ("good") cholesterol drop, but a 2026 meta-analysis of 31 randomized trials found no statistically significant average HDL change. Total cholesterol, LDL and triglycerides were modestly lower on average. In TRAVERSE, testosterone gel was noninferior to placebo for the primary composite of cardiovascular death, nonfatal heart attack and nonfatal stroke.

That's the average. Your panel can move differently, based on your treatment, your starting numbers, your blood sugar, your weight, other medicines and other health changes.

The warning sign is not a routine small HDL dip. The Endocrine Society says HDL below 30 mg/dL, especially without high triglycerides, should prompt clinical or biochemical investigation for anabolic steroid exposure. That guidance is about unusually low HDL and supraphysiologic androgen exposure, not proof that prescribed TRT caused the result.

Does TRT raise cholesterol?

TRT does not usually make the whole cholesterol panel worse. In randomized trials of men with low or low-normal testosterone, total cholesterol, LDL and triglycerides are often unchanged or modestly lower. HDL findings are mixed: older trials often found a small decline, while a 2026 meta-analysis found no statistically significant average HDL change. Much larger adverse HDL changes are most clearly linked to supraphysiologic androgen exposure.

That's the pattern. But "cholesterol" is really four or five different numbers. They don't all move the same way, and studies don't all agree.

So we pulled the main trials, pooled analyses and FDA drug labels into one table. Then we converted every result to mg/dL, the unit on U.S. lab reports.

The TRT Lipid Scoreboard

mg/dL changes. "—" means not reported in the published summary. Pooled values reported in mmol/L were converted (cholesterol × 38.67; triglycerides × 88.57).

How to read this table in 30 seconds

• "Placebo" rows are the strongest. They compare men on testosterone with men who weren't.
• "Before vs after" rows are weaker. Diet, weight, statins and age can all shift numbers over the same months.
• Small numbers are averages. A 2 mg/dL average drop hides men who dropped more and men who didn't move at all.

Why the studies don't all agree

Different studies look at different men. Older men vs. younger men. Men with diabetes vs. men without it. Gels vs. injections vs. pills. Six months vs. a year. Doses inside the normal range vs. doses far above it.

Notice the Kumar row. In men with diabetes, the authors reported HDL going up. Most other pooled data show it going down a little. That's not a mistake. It's a reminder that who you are shapes what happens.

And one more thing, before you blame testosterone for any change on your own panel:

"After TRT" is not the same as "because of TRT."

Does testosterone lower HDL?

Testosterone can lower HDL a little, but it does not do so in every trial. In the Testosterone Trials, HDL fell about 2 mg/dL more than placebo over a year, and older injection studies averaged about 4 mg/dL. But a 2026 meta-analysis of 31 randomized trials found no statistically significant average HDL change. Larger adverse HDL changes are most clearly associated with supraphysiologic androgen exposure.

We'll say it plainly: a small HDL drop is a real pattern in some TRT studies, but it is not universal. That matters because saying TRT "usually" lowers HDL overstates the newest pooled evidence.

Here's why a small drop is less scary than it sounds.

When HDL falls in replacement-dose trials, the average drop is usually small. In the 2018 Testosterone Trials it was 2.0 mg/dL versus placebo; in the older Whitsel injection meta-analysis it was 4 mg/dL. The 2022 individual-participant meta-analysis covering 5,601 men in 35 trials found no increase in cardiovascular or cerebrovascular events over the short to medium term and identified edema and a modest HDL lowering as adverse effects. The newer 2026 31-trial meta-analysis found no statistically significant average HDL change.

How testosterone can lower HDL

Your liver makes an enzyme called hepatic lipase. It breaks down HDL particles. Testosterone turns that enzyme up, so HDL gets cleared a bit faster. In one study of men starting testosterone injections, the size of the HDL drop tracked with the rise in hepatic lipase.

Is a lower HDL number actually bad?

Maybe not as bad as the number suggests. HDL's job is to help pull cholesterol out of artery walls. A lab report measures how much cholesterol HDL is carrying, not how well it's working.

In a 2012 study of 23 older men on testosterone gel, HDL levels didn't change. Neither did HDL's ability to pull cholesterol out of cells. Researchers still call the HDL question unsettled. But one lower number is not proof your HDL stopped doing its job.

The estradiol twist (don't self-treat this)

Some testosterone turns into estradiol, a form of estrogen. Men need it. The research on estradiol and HDL points in two directions:

• A review noted that adding an aromatase inhibitor (an estrogen blocker) to testosterone injections lowered HDL further.
• In the Testosterone Trials, men whose estradiol rose the most also saw the biggest HDL drops.

The takeaway is simple. Don't add an estrogen blocker to "protect" your HDL. That's a prescribing decision for your clinician. See our guide to TRT and estradiol levels.

When an HDL drop is not normal

Remember the warning sign we promised? Here it is.

The Endocrine Society's lipid guideline says that when HDL falls below 30 mg/dL, especially when triglycerides are not high, clinicians should look into anabolic steroid use. Its technical note is blunt: doses of androgens above normal levels lower HDL.

That matches the dose data. In healthy young men, HDL dropped about 8 mg/dL only at 600 mg a week. Lower doses didn't move it.

So a small HDL dip can fit the replacement-dose trial pattern. HDL below 30 mg/dL is a different signal: the Endocrine Society says clinicians should consider anabolic steroid exposure, especially when triglycerides are not high. That does not identify the cause by itself, and it is not a reason to change testosterone on your own.

Does TRT raise LDL?

Usually not. In controlled trials, LDL has often stayed similar or fallen modestly. The 2026 meta-analysis of 31 randomized trials found an average LDL difference of −6.64 mg/dL versus placebo/control; the Testosterone Trials found −2.3 mg/dL (P=0.051), and older injection studies averaged about −5 mg/dL. An individual LDL rise still deserves a broader look rather than an automatic assumption that TRT caused it.

The best data leans one way:

• Testosterone Trials: LDL down 2.3 mg/dL vs placebo (borderline significant).
• Injection studies: LDL down about 5 mg/dL on average.
• Men with type 2 diabetes: pooled trials reported LDL going down.

There is real counter-evidence, and you should know it. In 2014, researchers at the City University of New York and the University of Hong Kong reported a genetic study. It suggested that men who are born with higher testosterone tend to have lower HDL and may have higher LDL. That study asked a different question: lifelong genetics, not treatment. But it's why nobody should promise you that TRT lowers LDL.

Why your LDL might rise anyway

If your LDL climbed after you started TRT, testosterone is only one suspect. List what else changed over the same months:

• Diet. Eating more to "bulk," more saturated fat, more alcohol.
• Weight. Gaining weight, even muscle-building phases with more food.
• Medicine. Stopping or skipping a statin, or starting a new drug.
• Thyroid. An underactive thyroid can raise LDL. See TRT and hypothyroidism.
• Genetics and age. LDL tends to creep up with age regardless.
• The test itself. Different labs, fasting vs not fasting, normal day-to-day swings.
• Your testosterone dose. A level running above the normal range is worth checking.

LDL isn't the only "bad" number anymore

Two other tests now matter more than they used to:

• ApoB counts the number of particles that can clog arteries. One ApoB sits on each LDL-type particle.
• Lp(a), or lipoprotein(a), is an LDL-like particle. Your level is mostly set by your genes.

The 2026 ACC/AHA cholesterol guideline recommends measuring Lp(a) at least once in adulthood. It supports ApoB testing in some people, such as those with high triglycerides, diabetes, or LDL that's already low.

Here's an odd footnote. Small studies in healthy men from the 1990s found testosterone lowered Lp(a). One found an average drop of 37%. Another found the drop depended on where you started: no change when Lp(a) was already low, and 25% to 59% drops in others. Levels went back to baseline after testosterone stopped. These were small studies at doses above replacement. Interesting, but not a reason to take TRT.

What does TRT do to triglycerides?

Triglycerides do not move in one direction for every man on TRT. The 2026 meta-analysis found a modest average reduction of about 7 mg/dL versus placebo/control, while the Testosterone Trials found no significant treatment effect. A diabetes-focused meta-analysis found a larger average reduction of about 20 mg/dL. TRT is not a triglyceride treatment.

The pattern splits by who you are:

• Older men without diabetes: no change vs placebo in the Testosterone Trials.
• Men with type 2 diabetes: about a 20 mg/dL drop in pooled trials.
• Real-world clinic patients on long-acting injections: about a 16 mg/dL drop after six months.

Triglycerides move fast. Alcohol, sugar, a heavy meal before the test, weight changes and blood sugar control can all shift them in days or weeks. So a triglyceride change can reflect many things besides testosterone, including metabolic health, alcohol, diet, weight and testing conditions.

If triglycerides and blood sugar are your bigger worry, our guides to TRT and diabetes, TRT and weight loss and TRT with GLP-1 medicines go deeper.

Why steroid cycles and TRT aren't the same cholesterol question

Prescribed testosterone replacement and steroid use at bodybuilding doses are different exposures. The large HDL crashes people post online usually come from doses far above the normal range, often with other drugs mixed in. Results from steroid users don't predict what clinician-managed replacement will do.

A lot of what you read in forums mixes three very different things:

1. Replacement therapy for men with confirmed low testosterone, dosed to stay in the normal range.
2. Cycles at doses many times higher.
3. Stacks of several drugs at once, some that don't turn into estrogen at all.

The cholesterol numbers from groups two and three can look alarming. Cardiologists even use low HDL as one clue that someone may be using anabolic steroids. The Endocrine Society says the same thing.

That's why "my buddy's HDL went to 15" tells you almost nothing about a prescribed replacement plan. It's also why we won't give dosing, cycling or stacking advice here. Ever.

---

Does the type of testosterone change your cholesterol?

Somewhat, but the evidence does not support one simple formulation rule. Placebo-controlled lipid data include gels and mixed formulations, older injection studies found small HDL declines, and current FDA labels for oral testosterone undecanoate tell clinicians to monitor lipids. Compounded testosterone preparations are not FDA-approved, and FDA-reviewed product-specific lipid data for those compounded preparations are not available.

One important line: compounded testosterone preparations are not FDA-approved. A compounded preparation should not be described as an FDA-approved generic equivalent merely because it contains testosterone. The study numbers on this page come from FDA-approved products and research formulations; they should not be assumed to predict the lipid effects of a specific compounded preparation.

Does lower HDL mean TRT is hurting your heart?

A small HDL change by itself does not prove TRT is harming your heart. In TRAVERSE, men with cardiovascular disease or elevated cardiovascular risk had major cardiovascular events at 7.0% on testosterone gel versus 7.3% on placebo, meeting the trial's noninferiority standard. FDA labeling now also reflects class-wide blood-pressure increases, so cardiovascular follow-up is broader than cholesterol alone.

What TRAVERSE tested

TRAVERSE was built to answer the heart question directly. It enrolled men aged 45 to 80 who:

• had symptoms of low testosterone,
• had two fasting morning testosterone levels below 300 ng/dL, and
• already had heart disease or a high risk of it.

They used a daily 1.62% testosterone gel, adjusted to keep levels between 350 and 750 ng/dL, or a placebo gel. A large share of them were already taking cholesterol-lowering medicine.

The result: heart attacks, strokes and heart deaths combined happened in 7.0% of the testosterone group and 7.3% of the placebo group. Statistically, testosterone was not worse.

What it also found

This part rarely makes the headlines:

• Atrial fibrillation (an irregular heartbeat): 3.5% on testosterone vs 2.4% on placebo.
• Pulmonary embolism (a blood clot in the lungs): 0.9% vs 0.5%.
• Acute kidney injury: also more common on testosterone.

And about 61% of men in both groups stopped their study gel early. That's a real limit on what the trial can tell us over the long haul.

What the FDA changed in 2025 and 2026

On February 28, 2025, the FDA told testosterone makers to:

• add the TRAVERSE results to testosterone labeling,
• remove Boxed Warning language about an increased risk of adverse cardiovascular outcomes, and
• add or update blood-pressure warnings based on ambulatory blood-pressure studies.

FDA then requested additional testosterone-label updates in June 2026, including removal of the prior age-related-hypogonadism limitation-of-use language and revisions to prostate-related safety information. Those 2026 changes did not turn testosterone into a treatment for cholesterol or cardiovascular prevention.

What this does not mean

• It does not mean TRT prevents heart disease.
• It does not mean cholesterol stops mattering.
• It does not cover every type of testosterone. TRAVERSE used a gel only.
• It does not mean every man with heart disease is a good fit for TRT.

The American Urological Association puts it carefully. Its guideline tells clinicians to explain that low testosterone is itself a risk factor for heart disease, and that it can't yet be said for sure whether TRT raises or lowers the risk of heart events.

Your cholesterol changed after starting TRT. What now?

Compare the new panel with the one from before you started, marker by marker, not just total cholesterol. Note everything else that changed between the two tests. Then review the pattern with the clinician who manages your TRT or your heart risk. Don't stop or change testosterone or cholesterol medicine on your own.

Most men land on this page right here. A follow-up lab report came back, and a number is flagged. Here's a calm way through it.

The five-question check

Bring these to your next appointment:

1. How big is the change from my pre-TRT baseline? Small and large changes do not carry the same meaning, and the rest of the lipid panel matters too.
2. Did more than one marker move? A mixed pattern can have more than one cause, so do not reduce the whole panel to a single TRT effect.
3. What else changed? Weight, diet, alcohol, smoking, blood sugar, sleep, any medicine started or stopped.
4. Where is my testosterone level? Is it inside the normal range, or above it? Did my dose or type change?
5. Does this change my overall heart risk or my cholesterol plan? That's the question that actually decides what happens next.

Changes worth reviewing with your clinician

We don't interpret anyone's personal lab results. These are reasons to bring the full picture to the clinician managing your TRT or cardiovascular risk:

• HDL below 30 mg/dL, especially without high triglycerides. The Endocrine Society says this should prompt investigation for anabolic steroid exposure.
• A marked or persistent lipid change that is new for you.
• A testosterone concentration outside the clinician's intended treatment range.
• Blood pressure higher than before treatment. Current FDA labeling warns that testosterone products can raise blood pressure.
• Rising hematocrit (the share of your blood made of red cells). See TRT side effects.

Compare your before-and-after lipid panels

Put your numbers side by side in two minutes. Enter your total cholesterol, LDL, HDL and triglycerides from before TRT and from your latest test. Add the dates, and tick whether your weight, cholesterol medicine or testosterone dose changed in between.

You get:

• Every change in one view, in mg/dL and percent, so you can see which number actually moved.
• The tests worth asking about, including whether you've ever had Lp(a) measured.
• A printable question list built from what you entered, to take to your clinician.

It does math and builds questions. It does not tell you whether your numbers are safe, and it doesn't replace the person who knows your history.

Which cholesterol numbers matter most in 2026?

There's no special cholesterol target just because you take TRT. The 2026 ACC/AHA dyslipidemia guideline uses overall ASCVD risk, restores LDL-C and non-HDL-C treatment goals, recommends measuring Lp(a) at least once in adulthood, and supports selective ApoB testing when it improves risk assessment or treatment decisions.

In March 2026, the American College of Cardiology and American Heart Association replaced their 2018 cholesterol guideline. Four changes matter for men on TRT:

Non-HDL cholesterol is simple: total cholesterol minus HDL. It captures all the artery-clogging cholesterol in one number.

Notice what's missing from that list: HDL as a treatment target. Current dyslipidemia guidance focuses treatment decisions on atherogenic lipoproteins and overall ASCVD risk rather than trying to raise HDL to a specific target.

The same guideline calls healthy habits the foundation at every age and risk level. We'll come back to that.

---

Can you start TRT if you already have high cholesterol?

High cholesterol by itself doesn't decide whether TRT is right for you. What matters is a proper low-testosterone diagnosis, your overall heart risk, and whether a clinician can watch both. Men with a recent heart attack or stroke should wait three to six months, according to the American Urological Association.

Two guidelines frame this.

The Endocrine Society says testosterone should be used to treat symptoms of low testosterone, and not as a way to improve cholesterol or heart risk. So if anyone pitches TRT to fix your LDL, walk away.

The American Urological Association says not to start testosterone for three to six months after a heart attack, stroke or similar event.

Does high cholesterol mean online TRT is off the table?

High cholesterol alone does not decide whether care must be online or in person. The first questions are whether testosterone deficiency has been properly diagnosed, whether cardiovascular risk is understood, and whether the treating clinician can coordinate the issues that matter.

AUA guidance says testosterone therapy should not be started for three to six months after a cardiovascular event. The Endocrine Society advises against starting testosterone in men with myocardial infarction or stroke within the previous six months. More complex cardiovascular disease, uncontrolled risk factors, suspected inherited lipid disorders or recent major events are reasons to involve primary care, cardiology or another appropriate in-person clinician rather than treating this as a simple online-prescribing decision.

See why you need two low testosterone tests, what testosterone level qualifies for TRT and who should not take TRT for the separate diagnosis and contraindication questions.

One more thing before you start: fertility

Testosterone therapy can lower sperm production. If kids might be in your future, raise it before treatment, not after. Our guide to hCG with TRT explains the options doctors discuss. No one can promise fertility will be protected.

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.

Can you take TRT with a statin?

TRT and statins are commonly used in the same patients. In TRAVERSE, many participants were taking lipid-lowering therapy, and current oral-testosterone labels warn that lipid changes may require adjustment of lipid-lowering medicine. The clinician managing your statin should know you use testosterone; do not stop or change either prescription on your own.

Two facts matter here.

Testosterone labels expect this. The Kyzatrex label says changes in your cholesterol may require a dose change in cholesterol medicine, or stopping testosterone. Jatenzo's patient information says the same. So the two prescriptions need to talk to each other, even if they come from different clinicians.

Statins can lower testosterone a little. A pooled analysis of five placebo-controlled trials in 501 men found statins lowered testosterone by about 0.66 nmol/L, roughly 19 ng/dL, on average. Whether that matters for any one man isn't clear. It's not a reason to stop either medicine.

We see one mistake come up again and again in men's forums: someone starts TRT, their numbers look better, and they quietly stop their statin. Please don't. Statins are prescribed for your overall heart risk, not just one number. Talk to whoever prescribed it first.

---

How often should cholesterol be checked on TRT?

The Endocrine Society recommends a lipid panel and cardiovascular-risk assessment in adults with endocrine disorders. Current oral-testosterone labels such as Kyzatrex and Jatenzo also tell clinicians to monitor lipids periodically, particularly after starting. Major TRT guidelines do not set one universal lipid-testing interval for every testosterone patient, so follow-up timing should reflect the person's baseline lipids, cardiovascular risk, treatment and clinician judgment.

Here's what the rules actually say:

There's no single national schedule for lipid checks on TRT. Three useful questions for your clinician are:

1. Do I need a baseline lipid panel before treatment? The Endocrine Society recommends lipid assessment in adults with endocrine disorders.
2. When should my lipid panel be repeated? Product labels and individual cardiovascular risk can change the answer.
3. Have I ever had Lp(a) measured? The 2026 dyslipidemia guideline recommends at least one adult measurement for ASCVD risk assessment.

After that, your clinician sets the schedule based on your cardiovascular risk and treatment.

Does low testosterone cause high cholesterol?

Low testosterone and unhealthy cholesterol often show up together, and the American Urological Association calls low testosterone a risk factor for heart disease. But weight, insulin resistance and age drive both, so "linked" doesn't mean one causes the other. TRT is not a cholesterol treatment.

You've probably heard that cholesterol is the raw material your body uses to make testosterone. That's true. It doesn't mean eating more cholesterol raises testosterone. In a large U.S. health survey (NHANES 2013–2014), neither the cholesterol men ate nor the cholesterol in their blood was linked to their testosterone levels.

Weight, activity, sleep, diabetes and other metabolic factors can affect both testosterone and cardiovascular risk. Treat those as separate health issues rather than assuming that raising testosterone will fix cholesterol.

---

How to protect your cholesterol while on TRT

TRT does not replace standard cardiovascular-risk care. The 2026 dyslipidemia guideline still puts healthy eating, physical activity, avoiding tobacco and appropriate weight management at the foundation; medication decisions depend on overall ASCVD risk. Testosterone treatment should stay within the clinician's intended physiologic range rather than being pushed above it for nonmedical goals.

Short list, no gimmicks:

• Stay physically active. Regular activity supports cardiovascular health.
• Work toward a healthy weight if weight loss is appropriate for you.
• Avoid tobacco.
• Build meals around fiber-rich, minimally processed foods and keep saturated fat in check.
• Limit alcohol if it is raising triglycerides or otherwise affecting your health.
• Stay in the treatment range your clinician is targeting. Supraphysiologic androgen exposure has much stronger adverse HDL effects than replacement therapy.
• Don't add hormones, anabolic steroids or estrogen blockers on your own.

Choosing a TRT care route when cholesterol is part of the picture

This page is informational, so we are not naming a “best TRT provider for cholesterol.” The right care route depends on whether low testosterone has been properly diagnosed, how complex your cardiovascular risk is, and whether the clinician managing testosterone can coordinate with the clinician managing your cholesterol.

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, cardiology, 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.

Questions to ask any TRT program before you pay

1. Does the clinician review my cardiovascular history and current medicines?
2. If a lipid panel is needed, who orders it and who reviews it?
3. Will the program coordinate with my primary-care clinician or cardiologist if my cardiovascular risk is complex?
4. How will blood pressure and hematocrit be monitored?
5. What testosterone product or formulation may be prescribed, and is it FDA-approved or compounded?
6. What happens if a cardiovascular or laboratory issue makes online care a poor fit?

A note on online prescribing

Testosterone is a Schedule III controlled substance and requires a valid prescription. Federal telemedicine flexibilities currently allow DEA-registered practitioners to prescribe Schedule II–V controlled substances by telemedicine without a prior in-person medical evaluation when the federal conditions are met, through December 31, 2026. Prescribing must still comply with federal and state law. Because the temporary federal extension is scheduled to end after 2026 unless rules change again, anyone starting online care should verify the current requirements at the time of treatment.

How we built this page

We pulled placebo-controlled trials, pooled analyses, FDA drug information and current clinical guidelines, then converted every lipid result to mg/dL and labeled each one by who was studied, the type of testosterone and the study design. Provider details were checked on the dates shown. Conclusions marked as ours are editorial judgments, not medical advice.

• Evidence first. We gave placebo-controlled trials more weight than before-and-after studies.
• One unit. Results reported in mmol/L were converted to mg/dL (cholesterol × 38.67; triglycerides × 88.57).
• Separated, not blended. Replacement doses are kept apart from steroid-level doses, and FDA-approved products are kept apart from compounded ones.
• Dated. Anything that can change, like provider details, labels and telemedicine rules, carries a verification date. We recheck them regularly.
• No personal lab reading. We describe patterns. Your clinician interprets your results.

TRT Provider Guide is the independent decision resource for testosterone replacement therapy care. We are not a clinic, pharmacy, lab or medical practice. Read the full method in How We Review TRT Providers.

TRT and cholesterol: frequently asked questions

Does TRT raise cholesterol?

Usually not as a whole-panel effect. In randomized trials, total cholesterol, LDL and triglycerides are often unchanged or modestly lower. HDL can fall slightly in some studies, while the newest 2026 meta-analysis found no statistically significant average HDL change.

Why can TRT lower HDL?

Androgens can increase hepatic lipase activity, which changes HDL metabolism and can lower HDL-C. The size of the effect varies by exposure, formulation and population, and not every trial shows a significant HDL decrease.

How much does HDL drop on testosterone injections?

An older meta-analysis of intramuscular testosterone in hypogonadal men found an average HDL decrease of about 4 mg/dL. That does not predict every person's response, and newer mixed-formulation randomized evidence shows a smaller, nonsignificant average HDL change.

Does testosterone cypionate raise LDL?

Not usually. Injection studies averaged an LDL drop of about 5 mg/dL. A clear LDL rise is worth reviewing with your clinician.

Does TRT lower triglycerides?

Sometimes, mostly in men with type 2 diabetes or metabolic problems. In other men, triglycerides usually don't change much.

Is low HDL on TRT dangerous?

A small HDL change by itself does not prove TRT is harming your heart. HDL below 30 mg/dL is different: the Endocrine Society says clinicians should investigate possible anabolic steroid exposure, especially when triglycerides are not high.

Can I take TRT and a statin together?

Yes, many men do. Tell both prescribers. Never stop a statin on your own because you started TRT.

Do statins lower testosterone?

Slightly, on average. One pooled analysis found a drop of about 19 ng/dL in men. Whether that matters for you isn't clear.

Can high cholesterol stop me from getting TRT?

Not by itself. Your diagnosis, overall heart risk and recent heart history decide it. Men with a heart attack or stroke in the past three to six months should wait.

Will TRT fix my cholesterol?

No. The Endocrine Society says testosterone should treat symptoms of low testosterone, not cholesterol or heart risk.

Does oral testosterone affect cholesterol more than injections?

FDA labels for oral testosterone undecanoate report lower HDL and ask for lipid checks. Head-to-head comparisons with injections are limited.

Should I get ApoB or Lp(a) tested before TRT?

The 2026 ACC/AHA guideline recommends measuring Lp(a) at least once in adulthood, and ApoB for some people. Ask your clinician whether they fit you.

Is TRT bad for your heart?

TRAVERSE found testosterone gel noninferior to placebo for the primary composite of cardiovascular death, nonfatal heart attack and nonfatal stroke in the men studied. Some other adverse events, including atrial fibrillation and acute kidney injury, occurred more often with testosterone, and FDA labeling now warns that testosterone products can raise blood pressure.

Does eating more cholesterol raise testosterone?

No. In a large U.S. survey, cholesterol intake and blood cholesterol weren't linked to testosterone levels.
