What we discuss after bloodwork, not before it.
Testosterone is a hormone that is FDA-approved, prescription only.
Also known as TRT, Testosterone cypionate, AndroGel, Testosterone replacement therapy
Testosterone therapy (TRT) is used for men with hypogonadism confirmed by symptoms and repeated blood tests. It comes as injections, gels, patches, pellets and oral capsules.

Approved by the FDA. A licensed clinician has to decide it is right for you and prescribe it. FDA-approved, prescription only, and a Schedule III controlled substance. In February 2025 FDA removed the cardiovascular-risk language from the boxed warning after the TRAVERSE trial, added blood pressure warnings, and kept the limitation of use for age-related low testosterone.

Interest is the beginning, not a diagnosis or a treatment decision. Explore each milestone to understand the process before comparing providers.
Step 1 of 4
Notice the concerns that apply to you. You do not need to decide what is causing them.
A clinician can help determine whether testosterone, another condition or more evaluation fits your symptoms.
Testosterone therapy replaces the hormone directly. Your body notices the outside supply and turns down its own signal to the testes, which is why natural production and sperm counts usually fall while you are on it.
That is different from pills like enclomiphene, which nudge your own system to make more. Replacing the hormone raises levels more predictably, but it trades away fertility for as long as you take it, and sometimes for a while after.



Strong evidence for treating confirmed hypogonadism; TRAVERSE found no increase in major heart events. Benefits in men with normal levels are not established.
What trials and prescribing information measured over time. Everyone responds differently.
A 2011 review of treatment studies found changes in sexual interest and mood often began within about three to six weeks.
The same review found erections and body composition changes took longer, often three months or more. The AUA suggests discussing stopping if symptoms have not improved three to six months in.
Changes in fat and lean mass tended to level off between six and twelve months. The rise in red blood cells peaked around nine to twelve months, which is why labs continue.
The Endocrine Society recommends checking levels, blood counts and prostate risk three to twelve months after starting, then yearly.
Urology and endocrinology guidelines agree on the basics: confirm the diagnosis with repeat morning tests, talk about fertility first, and keep checking blood counts and prostate markers once treatment starts.
The American Urological Association guideline uses a total testosterone below 300 ng/dL as a reasonable cut-off, measured on two separate early-morning tests, together with symptoms.
AUA: Testosterone Deficiency guideline (2018, validity confirmed 2024)The AUA guideline says testosterone should not be prescribed to men who are currently trying to conceive, and men who want children later should be counseled first.
AUA: Testosterone Deficiency guideline (2018, validity confirmed 2024)The Endocrine Society's 2018 guideline recommends against routinely screening men without symptoms and against routinely treating all men over 65 with low levels; for older men, it advises deciding case by case.
Endocrine Society: Testosterone therapy in men with hypogonadism, clinical practice guideline (JCEM 2018)In February 2025 FDA required all testosterone labels to include the TRAVERSE results, removed the cardiovascular language from the boxed warning, added a warning about higher blood pressure, and kept the limitation that it is not approved for low testosterone caused by aging alone.
FDA: Class-wide labeling changes for testosterone products (Feb 2025)Testosterone is a Schedule III controlled substance and is prohibited in tested sport under the WADA list.

Only a licensed clinician who knows your history can decide whether it is right for you.
These save with the compound when you add it to My Journal, so they’re on the printout for your visit.

Fill in an online health questionnaire about symptoms, medical history and fertility plans.
Get labs: most programs send an at-home kit or book a draw at a lab like Quest; some accept recent results from your own doctor.
A licensed clinician reviews your results and history, sometimes by video, and decides whether treatment is appropriate. Some states require a live visit.
If prescribed, medication ships to you from a licensed pharmacy, usually on a monthly or longer refill schedule.
Expect repeat labs a few months after starting, then at regular intervals, to check levels, red blood cells and PSA.
Some services let you order common lab tests yourself, so the results are ready for your visit. Your clinician decides which labs, if any, you need, and what the results mean.

Guidelines ask for symptoms plus two low results on separate early-morning blood tests. Levels swing during the day and after poor sleep or illness, so one test is not enough.
Usually, yes. Outside testosterone tells your body to stop making sperm. If you want children now or soon, ask about options that keep fertility, such as clomiphene-type drugs, before starting.
The large TRAVERSE trial found no increase in major heart events in men with low testosterone and heart risk. It did see more atrial fibrillation and blood clots in the lungs, and FDA added a blood pressure warning in 2025. Your clinician will weigh your own risks.
Yes. It is a controlled substance, but federal telemedicine rules currently allow it to be prescribed without an in-person visit, and several providers do so after labs. Some states add their own requirements.
Not necessarily, but symptoms and low levels usually return if you stop, and it can take time for your own production to recover. Talk through a plan before you start.
This is not a complete list of risks. Read the full prescribing information and any Medication Guide, and talk to a licensed clinician or pharmacist about your own situation. If you have a severe reaction, call 911. You can report side effects to the FDA through MedWatch at 1-800-FDA-1088.
