What Is a TRT Clinic? Services, Costs, and Risks

A TRT clinic is a medical practice that specializes in diagnosing and treating low testosterone, a condition clinically known as hypogonadism. These clinics range from brick-and-mortar offices staffed by urologists or endocrinologists to direct-to-consumer telemedicine platforms where nearly everything happens through a phone app. The services, pricing, and quality of care vary enormously depending on which model you walk into, and the rapid commercialization of testosterone therapy has blurred the line between legitimate medicine and aggressive upselling.

How TRT Clinics Diagnose Low Testosterone

A responsible TRT clinic starts with bloodwork, not a prescription. The standard diagnostic workup includes measuring total testosterone (usually drawn in the morning, when levels peak), free testosterone, and often a panel of related hormones like luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, and prolactin. The goal is to confirm that testosterone is genuinely low and to figure out why. Low testosterone has been estimated to affect roughly 39% of men aged 45 and older who present to primary care in the United States, though that figure reflects men who showed up with symptoms rather than the general population.¹

Guidelines from major endocrinology and urology organizations call for at least two separate morning blood draws showing low testosterone before starting treatment. They also call for evaluation of symptoms: fatigue, low libido, erectile dysfunction, loss of muscle mass, depressed mood, or difficulty concentrating. A clinic that prescribes testosterone based on a single borderline lab result and a quick questionnaire is cutting corners, and some do. A global analysis of websites offering testosterone treatment found that the information presented commonly diverges from evidence-based clinical guidelines, with many sites promoting claims that lack guideline consensus.²

What Treatments TRT Clinics Typically Offer

The core service is testosterone itself, but clinics differ in which formulations they provide and what they bundle alongside it. Testosterone comes in several forms, each with trade-offs in convenience, cost, and how closely they mimic natural hormone patterns.

Injections: The most common option at TRT clinics. Testosterone cypionate or enanthate is injected intramuscularly or subcutaneously, typically every one to two weeks. Injections produce the highest peak testosterone levels but also the widest swings between doses. They tend to be the cheapest formulation.
Topical gels and creams: Applied daily to the skin, gels deliver a steadier testosterone level but carry a risk of transferring the hormone to others through skin contact. They are more expensive per month than injections.
Pellets: Small implants placed under the skin every three to six months. Pellets offer long-lasting delivery without daily or weekly dosing, but insertion is a minor in-office procedure, and dosing adjustments are difficult once they are in place.
Patches and oral formulations: Less commonly offered at dedicated TRT clinics. Patches can cause skin irritation, and newer oral testosterone options are available but still relatively expensive.

Short-acting formulations like daily gels and patches mimic the body’s natural daily rhythm more closely, while long-acting options like pellets and less-frequent injections offer better adherence but are more likely to push testosterone above normal levels for stretches of time.³ Injectable testosterone also produces significantly higher testosterone levels overall compared to gels or pellets.⁴

Ancillary Medications

Many TRT clinics offer add-on medications alongside testosterone, and this is where things get more specialized. Human chorionic gonadotropin (hCG) is frequently prescribed to maintain testicular function and preserve some degree of fertility while on testosterone. hCG works by directly stimulating the cells in the testes that produce testosterone, keeping them active even when the brain’s hormonal signals have been suppressed by external testosterone.⁵

Aromatase inhibitors like anastrozole are another common add-on. Testosterone partially converts to estrogen in the body, and in some men this conversion pushes estrogen levels high enough to cause side effects like breast tissue growth or water retention. Anastrozole blocks that conversion. In patients with elevated estrogen on testosterone therapy, a low dose of anastrozole normalized estrogen levels in about three-quarters of cases while maintaining testosterone levels.⁶ That said, aromatase inhibitors are used off-label in this context, and not every man on testosterone needs one. A clinic that automatically bundles anastrozole into every patient’s protocol regardless of their estrogen levels is practicing a one-size-fits-all approach that does not match clinical evidence.

Telemedicine Platforms vs Traditional Medical Settings

The TRT landscape has split into two broad models. Traditional clinics and academic medical centers offer in-person evaluation, draw blood on-site, and typically bill through insurance. Direct-to-consumer telemedicine platforms, which exploded in popularity around 2020, handle consultations by video, ship medications to your door, and usually operate on a subscription or cash-pay model.

An analysis comparing telemedicine TRT platforms to a tertiary medical center found that the online platforms were largely following practice guidelines in how they evaluated and treated patients.⁷ The initial workup and follow-up protocols looked similar. Where the two models diverged sharply was cost, which is worth its own discussion.

What TRT Actually Costs

This is where the gap between clinic types becomes hard to ignore. The same study comparing telemedicine platforms to a tertiary medical center found that 12 months of intramuscular testosterone treatment through online platforms ranged from about $1,586 to $4,200. Through a traditional medical center with insurance, the same treatment ranged from roughly $134 to $1,333.⁷ The telemedicine premium is partly explained by the bundled services, convenient delivery, and cash-pay model, but the price difference is substantial enough that anyone with private insurance or Medicare should think carefully before defaulting to an online platform.

Insurance coverage for testosterone therapy itself is reasonably common when the diagnosis is documented. An analysis of major U.S. health plans found that among plans with publicly accessible policies on hypogonadism, 91% viewed androgen replacement as medically necessary for a standard hypogonadal patient.⁸ The catch is that only about 62% of major plans had publicly accessible policies on hypogonadism at all, so coverage exists but can take effort to confirm.

The ancillary medications add up too. hCG, anastrozole, and other add-ons are often not covered by insurance when used alongside testosterone, and telemedicine clinics typically charge a markup on these. Monthly costs for a full “protocol” at an online men’s health clinic can easily run $200 to $400 per month before any blood work fees.

Fertility Is the Risk Most Men Underestimate

If you are considering children in the future, this is the single most important thing to understand before walking into a TRT clinic. Exogenous testosterone suppresses the brain’s signals that drive sperm production. When you introduce testosterone from outside the body, the hypothalamus and pituitary gland register that testosterone levels are adequate and stop sending the hormonal signals (LH and FSH) that tell the testes to make both testosterone and sperm. Intratesticular testosterone levels can drop low enough to severely compromise or halt sperm production entirely.⁹

High-dose testosterone studies in healthy men have shown that complete absence of sperm (azoospermia) occurs in roughly 50 to 70% of men treated, with the remainder showing severely reduced counts.¹⁰ This is why testosterone has been actively studied as a male contraceptive. A responsible TRT clinic will ask about your fertility goals before prescribing, and if you want children, will either defer testosterone treatment, prescribe alternatives like clomiphene citrate, or add hCG to try to maintain some testicular function.

Cardiovascular and Blood-Related Risks

The cardiovascular safety of testosterone therapy has been debated for over a decade, and the evidence has evolved considerably. A systematic review and meta-analysis looking at randomized controlled trials found no statistically significant increase in the risk of heart attack, stroke, arterial blood clots, venous blood clots, or death from testosterone therapy in men with confirmed low testosterone.¹¹ Observational data, which follows larger numbers of men in the real world, actually suggested reduced rates of several of these events. The review concluded that testosterone therapy in men with levels below the hypogonadal threshold appears safe from cardiovascular events.

The more concrete blood-related risk is polycythemia, an increase in red blood cell concentration. Testosterone stimulates red blood cell production, and when levels climb too high, the blood thickens, raising the risk of clots. This is especially pronounced with injectable testosterone. One study found that a hematocrit above 50% (the threshold for polycythemia) occurred in about two-thirds of men on injectable testosterone, compared to about 13% on gels and 35% on pellets.⁴

Men who develop polycythemia while on testosterone do face a measurably higher risk of serious cardiovascular events and blood clots compared to men on testosterone whose blood counts stay normal.¹² This is why regular blood monitoring is non-negotiable. Clinical guidance calls for checking hematocrit every three to six months during the first year of treatment and annually afterward, along with monitoring blood pressure and lipid levels in higher-risk patients.¹³ A TRT clinic that does not enforce follow-up blood work is not providing safe care.

Prostate Safety

Fear that testosterone causes prostate cancer has lingered for decades, and it remains one of the most common concerns men raise when considering TRT. The current evidence is reassuring, if not entirely settled. A large randomized trial found no significant difference in high-grade prostate cancer between men receiving testosterone and those on placebo. Rates of prostate biopsy, urinary retention, and surgical procedures were also similar between groups. Testosterone-treated men did see a modest rise in PSA (prostate-specific antigen), a blood marker sometimes associated with prostate issues, but the increase did not translate to more cancer diagnoses.¹⁴

A meta-analysis of the broader literature reached the same conclusion: testosterone therapy for symptomatic hypogonadism does not appear to increase PSA levels or the risk of developing prostate cancer.¹⁵ That said, testosterone is contraindicated in men with active prostate cancer, and regular PSA monitoring while on therapy remains standard practice. The concern is not that testosterone initiates cancer but that it could accelerate growth of a cancer already present.¹⁶

Psychological and Cognitive Effects

Many men seek out TRT clinics primarily for mood-related symptoms: brain fog, low motivation, irritability, or persistent fatigue. The evidence on psychological outcomes is mixed in ways that matter. A two-year study of young and middle-aged hypogonadal men found that testosterone therapy improved cognitive measures like attention, visual scanning, and processing speed, but did not produce significant changes in emotional state or quality of life scores.¹⁷

On the other side, a large database analysis found that testosterone use was independently associated with higher rates of major depressive disorder and suicide attempts or intentional self-harm.¹⁸ This does not necessarily mean testosterone caused those outcomes. Men seeking testosterone therapy are already more likely to have mood disturbances, and observational data cannot untangle whether the treatment contributed to the problem or was sought because the problem existed. But the finding is a reminder that testosterone is not an antidepressant, and clinics that market TRT as a solution for depression are getting ahead of the science.

What Happens When You Stop

One question that TRT clinics rarely volunteer answers to is what happens if you discontinue treatment. The short version: your body needs time to restart its own testosterone production, and that restart is not guaranteed to go smoothly.

A study following 151 men who stopped TRT found that about 61% experienced a return of their original symptoms with testosterone dropping back to hypogonadal levels, while roughly 39% maintained their improvements with normal testosterone levels after stopping. The two strongest predictors of who kept feeling well were how long they had been on treatment and whether they exercised regularly. Exercise, in particular, was a powerful independent predictor of maintaining response after cessation.¹⁹

A separate study that interrupted testosterone therapy in older hypogonadal men found that stopping led to worsening of obesity measures, urinary symptoms, erectile function, and overall symptom scores. When treatment resumed, those declines reversed.²⁰ The takeaway from these findings is that hypogonadism may require lifelong treatment for many men, and a TRT clinic should be forthcoming about that possibility before you start.

Fertility recovery after stopping is a particular concern. While most men do eventually recover sperm production, the timeline is highly variable and depends on factors like how long you were on testosterone, your age, and your baseline testicular function before treatment. In some men, spontaneous recovery does not happen at all, and medications like clomiphene or gonadotropin therapy may be needed to jumpstart the process.²¹

The Marketing Problem

The business of TRT has grown much faster than the prevalence of the conditions it treats. Testosterone prescriptions have risen dramatically in recent years without a corresponding increase in organic hypogonadism diagnoses, and research has drawn a link between direct-to-consumer advertising and increased testosterone testing, more prescriptions, and in some cases, prescriptions without proper testosterone testing at all.²²

This does not mean every TRT clinic is irresponsible. Many provide thorough evaluation, careful monitoring, and evidence-based treatment. But the commercialization of testosterone therapy has created a landscape where some clinics are essentially wellness businesses with a medical veneer. Red flags include clinics that guarantee you will qualify for treatment before seeing your labs, that advertise testosterone as an anti-aging solution, that do not perform follow-up blood work, or that bundle expensive add-on medications into every patient’s protocol without individualized justification.

Women and Testosterone Therapy

Though TRT clinics primarily market to men, testosterone therapy for women is a growing niche, and some clinics offer it. The evidence base here is substantially thinner. The Endocrine Society has recommended against the general use of testosterone in women, with one narrow exception: short-term treatment of postmenopausal women with hypoactive sexual desire disorder (persistently low sexual desire causing distress). In that specific population, physiological doses of testosterone have shown short-term efficacy and acceptable safety.²³

For other common claims, the guidelines recommend against using testosterone in women for infertility, cognitive health, cardiovascular or metabolic benefit, bone health, or general well-being. A major limitation is that physiological testosterone preparations designed for women are not available in many countries, including the United States, which means women often receive compounded formulations or off-label doses of products made for men. Long-term safety data for testosterone in women remain lacking, so any woman receiving therapy should be monitored for signs of androgen excess like acne, hair growth, or voice changes.²⁴

A TRT clinic that aggressively markets testosterone to women for energy, weight loss, or anti-aging is operating well outside what the evidence supports. The science may eventually catch up to some of these claims, but it has not yet.
