The single most misleading number in online testosterone replacement therapy is the monthly price. Not because clinics lie — they technically do charge what they advertise — but because what they advertise is systematically incomplete.

Here is how the math actually works, and why the true annual cost is the only number that matters.

The three hidden cost categories

Startup fees. Many clinics charge a one-time consultation, blood panel, or activation fee to start. This ranges from $0 to $199. Amortized over 12 months, even a $99 startup fee adds $8/month to your effective cost.

Lab work. You need blood work to start TRT (at minimum: total testosterone, free testosterone, LH, FSH, estradiol, CBC, PSA). You need monitoring labs every 3–6 months while on therapy. Labs cost $75–$200 per draw if not included. At two draws per year, that is $150–$400 in additional annual cost that many advertised prices do not include.

Medication cost vs. program cost. Some clinics advertise the medication cost alone and charge separately for consultations, prescription renewals, and ongoing clinical monitoring. Others bundle everything. You cannot compare two programs without knowing what is included.

The math on the most commonly compared clinics

Maximus: Advertises $100/month including testosterone cypionate, ongoing monitoring, and consultations. No separate lab fee. True annual cost: approximately $1,200. This is clean — what they say is what you pay.

TRT Nation: $99/month, labs included. True annual: $1,188.

A clinic advertising $49/month (medication only): Add $150–$200 in startup labs, $150–$300 in monitoring labs over the year, and a $49–$99 consultation fee. True annual: $900–$1,400. Potentially more expensive than programs with a higher headline monthly price.

Why this matters for decision-making

Labs-included vs. labs-excluded is the single biggest variable in TRT cost transparency. If a clinic includes labs in their monthly fee, you are almost always paying less over a year than a cheaper-looking clinic that does not.

The second variable: does the monthly price include ongoing consultations and prescription renewals, or do you pay extra each time a physician reviews your results?

We calculate true annual cost for every clinic on ClinicLayer by factoring in: monthly subscription, required startup fees, lab cost (either included or market rate for 2 draws/year), and typical consultation costs. That number is what we rank by.
