Common questions about TRT.
What is testosterone replacement therapy (TRT)?
TRT is a treatment that supplements testosterone in men whose own levels are clinically low, usually through injections, gels, patches or pellets prescribed by a licensed clinician after blood testing confirms a deficiency.
How do I know if I actually have low testosterone?
A real diagnosis needs a blood test, typically drawn in the morning on two separate days, interpreted alongside your symptoms by a clinician. A symptom questionnaire like our ADAM tool can help you prepare for that conversation, but it is not a diagnosis on its own.
Is TRT safe?
For men with a confirmed diagnosis, TRT is generally considered safe under clinician supervision, with monitoring for effects like elevated hematocrit. It carries real risks and contraindications, which is why ongoing lab work and a licensed prescriber are part of responsible treatment.
How much does TRT typically cost?
Cost varies widely by clinic, formulation and whether insurance covers your specific diagnosis. Telehealth TRT programs commonly range from roughly 120 to 300 dollars a month all-in; traditional clinics and insurance-covered care can look very different. See our Choosing Care guides for what drives that range.
Can I get TRT without seeing a doctor?
No. Testosterone is a prescription controlled substance in the United States, and legitimate treatment always requires evaluation and ongoing monitoring by a licensed clinician. Be cautious of any source that offers it without that.
