How to Start a TRT Clinic: Licensing, Equipment, and Software

Key Takeaways: Testosterone replacement therapy (TRT) clinics generate $250 to $500 per client per month in recurring subscription revenue. A clinic with 100 active clients produces $25,000 to $50,000 monthly from this single service line. Startup costs run $80,000 to $250,000. Every state requires a prescribing provider and DEA registration for controlled substance handling. The business model is subscription-based: clients stay for 12 to 36 months on average.

Why TRT clinics are a strong business model

Testosterone replacement therapy is a long-term treatment. Clients who start TRT typically stay on therapy for years, creating a subscription revenue model that most clinics envy. Unlike one-time aesthetic treatments, TRT produces predictable monthly revenue with minimal client acquisition effort after the initial enrollment.

The addressable market is growing. Hypogonadism affects an estimated 20% to 40% of men over 45, and awareness of symptoms (fatigue, low libido, brain fog, muscle loss) is increasing through direct-to-consumer advertising and social media. Google searches for "low testosterone clinic near me" have grown consistently year over year since 2020.

Licensing and regulatory requirements

Prescribing authority

TRT involves prescribing testosterone, which is a Schedule III controlled substance under the DEA. This means stricter regulatory oversight than non-controlled medications like GLP-1s. You need a prescribing provider (MD, DO, NP in most states, or PA under physician supervision) with an active DEA registration.

If you are not a prescriber, you need a Medical Director or employed prescriber who holds both a state medical license and DEA registration. The Medical Director model works, but the provider must be meaningfully involved in patient care, not just signing protocols.

DEA registration

Every location that stores, dispenses, or administers testosterone must have its own DEA registration. This is a per-location requirement, not a per-provider one. The DEA registration process takes 4 to 8 weeks. You must also maintain records of all controlled substance transactions: quantity received, quantity dispensed, to whom, and remaining inventory. Expect DEA audits.

State-specific requirements

Some states require a specific facility license for clinics that administer injections. Others have telemedicine restrictions that limit remote prescribing of controlled substances. Texas, for example, requires an in-person initial evaluation before prescribing testosterone via telemedicine. California's corporate practice of medicine doctrine may require an MSO structure if the owner is not a physician.

Startup costs breakdown

Lean model ($80,000 to $150,000)

A consultation-focused clinic with 1 to 2 exam rooms, basic lab draw supplies, a centrifuge for in-house processing if needed, and a small inventory of testosterone (cypionate, enanthate). One part-time prescriber, one medical assistant. This works for providers adding TRT to an existing men's health or wellness practice.

Full-service model ($150,000 to $250,000)

A dedicated TRT and men's health clinic with 3 to 4 rooms, lab draw station, body composition analyzer, retail supplements, full-time prescriber, medical assistant, and front desk staff. Professional buildout with a masculine but welcoming aesthetic. Marketing budget for the first 6 months. This is the model for a standalone TRT clinic targeting the men's optimization market.

Equipment and supplies

Core equipment: exam table, phlebotomy chair, centrifuge (if processing labs in-house, $2,000 to $5,000), controlled substance safe (DEA requirement, $500 to $2,000), refrigerator for testosterone storage, and a body composition analyzer (optional but adds value, $3,000 to $12,000). Per-client supplies: syringes, needles (drawing and injection), alcohol wipes, bandages, and sharps containers. Supply cost per injection visit is $3 to $8.

Testosterone cypionate (the most commonly prescribed form) costs $10 to $30 per vial at wholesale. Each vial covers 2 to 4 weeks of treatment depending on dosage. Your medication cost per client per month is $15 to $40, leaving significant margin on subscription fees of $200 to $400 per month.

The subscription model

TRT clinics operate on a subscription model because the treatment is ongoing. A typical structure: $199 to $399 per month covering the provider consultation (in-person or telehealth), testosterone medication, injection supplies (for self-administration clients), and lab work every 3 to 6 months.

What to include in the subscription

The most successful TRT clinics bundle everything into one monthly fee: provider visit (every 4 to 8 weeks), testosterone medication, injection supplies, and quarterly lab work (total testosterone, free testosterone, estradiol, hematocrit, PSA). This removes friction from the client experience. No surprise lab bills, no pharmacy runs, no separate appointment fees.

Add-on revenue

Common add-ons that increase average revenue per client: HCG ($50 to $100/month for fertility preservation), anastrozole ($30 to $50/month for estrogen management), DHEA or pregnenolone supplements ($20 to $40/month), peptide therapy (BPC-157, CJC/Ipamorelin at $150 to $300/month), and ED medications (sildenafil, tadalafil at $50 to $100/month). A client on TRT plus two add-ons generates $350 to $600 per month.

Client retention

TRT has naturally high retention because stopping treatment means symptoms return. The average TRT client stays enrolled for 18 to 36 months. The main reasons clients leave: side effects that are not managed (acne, elevated hematocrit, mood changes), billing friction, or feeling that the clinic is not monitoring their health adequately.

Lab monitoring cadence

Schedule labs at baseline, 6 weeks after starting, 12 weeks, and then every 6 months. Each lab review is a touchpoint that reinforces the value of the subscription. Automate lab reminders 7 days before the due date, and follow up if labs are not completed within 14 days. Clients who skip labs are at higher risk of discontinuing.

Software requirements

TRT clinic software needs to handle: subscription billing with automatic renewal and failed payment recovery, treatment protocol tracking (medication, dosage, injection frequency, injection site rotation), lab result management (import, flag out-of-range values, track trends over time), consent and intake forms (signed digitally), and telehealth integration for remote follow-ups.

The unique challenge is controlled substance tracking. Your software should log every testosterone dispensation: date, client, quantity, lot number, and remaining inventory. This data is required for DEA audits. Many general clinic platforms do not handle controlled substance logging. Choose a platform that either includes this or integrates with a dispensing system that does.

Marketing a TRT clinic

TRT clients search with high intent and specific symptoms. Target keywords like "low testosterone clinic [city]," "TRT near me," "testosterone replacement therapy cost," and symptom-based queries like "always tired low energy men." Google Ads with location targeting generates the most efficient acquisition for new TRT clinics.

Content marketing works well for TRT because the education gap is large. Most men know they feel tired but do not know that testosterone testing is a 15-minute blood draw. Blog content addressing symptoms, testing, and treatment options builds trust and captures organic search traffic over time. Before-and-after energy and body composition testimonials (with consent) are highly effective.

Frequently asked questions

How profitable is a TRT clinic?

A TRT clinic with 100 active subscription clients at $300 per month average generates $30,000 monthly. With medication costs of 10% to 15%, staffing at 25% to 30%, and overhead at 15% to 20%, net margins run 30% to 40%. TRT clinics often reach profitability faster than aesthetic clinics because the subscription model creates predictable revenue from month one.

Can a nurse practitioner own a TRT clinic?

In states with full practice authority (about 27 states), NPs can own and operate TRT clinics independently. In restricted practice states, NPs need a collaborative agreement with a physician. In some states, the corporate practice of medicine doctrine may require the clinical entity to be physician-owned regardless of who the day-to-day prescriber is.

Start with the subscription, build from there

A TRT clinic is a subscription business that happens to be medical. Get the subscription model right first: one monthly fee, everything included, automatic billing. Then build the clinical infrastructure around it. The clinics that struggle are the ones that start with the medical complexity and bolt on the business model later.
