Lab-confirmed TRT, managed online
If you have symptoms of low testosterone, a licensed clinician will confirm the diagnosis with blood tests before anything is prescribed, then monitor you over time. Treatment starts at $149 a month.

Two morning blood tests confirm low testosterone before anything is prescribed, and your clinician checks for reversible causes first.
Your clinician walks you through injections, gels and other options so you can pick what fits your routine and how steady you want levels.
Follow-up visits and lab work track your levels and safety over time, with dose adjustments when your results or symptoms call for them.
Treatment starts at $149 a month. Your first visit costs nothing, and insurance isn't required.
Book a phone or video slot. The first consultation is free and you do not need insurance.
In about 5–10 minutes, a licensed clinician reviews your symptoms, health history and medicines, and orders morning blood tests if you do not have recent results.
If low testosterone is confirmed and TRT is appropriate, your clinician explains the options, benefits and risks before prescribing. Controlled-substance rules may require a particular visit type.
Your prescription is sent to a licensed U.S. pharmacy, with instructions on how to use it and what side effects to watch for.
Follow-up labs a few months after starting, then periodically, check your levels, blood count and other markers so the dose can be fine-tuned.
You have symptoms such as low libido or fatigue, and two separate morning tests show testosterone below the normal range.
Sleep, weight, alcohol, medicines and mood have been considered, and low testosterone still explains your symptoms.
TRT is usually long-term and requires regular blood tests for testosterone, red blood cell count and, for many men, PSA.
Testosterone therapy can sharply lower sperm production. If you want children in the near future, ask about enclomiphene or other options that support your own production.
Men with breast cancer, known or suspected prostate cancer, a very high red blood cell count or untreated severe sleep apnea are not candidates for TRT online.
Testosterone is prescribed to treat a diagnosed deficiency, not to boost muscle or performance in men with normal levels.
| Feature | Injections | Gels and solutions | Other forms |
|---|---|---|---|
| How it's used | Into the muscle or under the skin | Applied to the skin | Patches, nasal gel, oral capsules or long-acting shots |
| How often | Weekly or every 1–2 weeks | Daily | Varies by product |
| Main consideration | Smaller, more frequent doses keep levels steadier | Can transfer to others through skin contact | Each has its own pros, cons and costs |
Testosterone supports sex drive, erections and energy. It also helps maintain muscle, bone strength and red blood cell production. When the testes do not make enough, or the brain does not signal them properly, men can develop low testosterone, also called hypogonadism. Symptoms may include low libido, fewer morning erections, fatigue, low mood, reduced bone density and loss of muscle and body hair.
Many of these symptoms have other causes too, such as poor sleep, sleep apnea, depression, weight gain, heavy drinking, thyroid problems or certain medicines. That is why a diagnosis rests on symptoms plus at least two early-morning blood tests showing low testosterone. Your clinician will also look for reversible causes before suggesting treatment, and may check LH and FSH to tell whether the problem starts in the testes or the pituitary.
Testosterone is a Schedule III controlled substance under federal law, so it carries extra prescribing rules. It is prescribed only when the evidence supports it. Doses aim for a normal range rather than above it, and regular blood work helps keep treatment safe.

The choice depends on your preference, lifestyle and how steady you want levels to be. Your clinician will explain the trade-offs.
Because testosterone is a Schedule III controlled substance, federal law limits how it is prescribed and refilled, and states can add their own rules. Federal telemedicine flexibilities from the DEA currently allow clinicians to prescribe some controlled substances without a prior in-person visit, and these have been extended through December 31, 2026.
Those rules can change. Depending on federal and state requirements at the time, you may need a specific type of visit, such as a live video visit, or an in-person evaluation before starting or continuing treatment. If that applies to you, the care team will tell you what is needed. Never share your testosterone with anyone, and store it securely.
In men with true deficiency, sexual desire often improves first, within a few weeks to a few months. Energy and mood may follow, while changes in muscle, fat and bone take many months and depend on exercise and diet. Some men notice little difference; if so, your clinician will revisit the diagnosis rather than simply raising the dose.
If you stop TRT, testosterone levels usually fall back toward where they started. Your own production may take months to recover, and in some men it does not fully return. Talk with your clinician before stopping.
TRT is effective for men with confirmed deficiency, but it changes several body systems. Regular blood work and honest reporting of symptoms keep it as safe as possible.

Your clinician looks for symptoms plus at least two early-morning blood tests showing low testosterone. Additional tests, such as LH, FSH and a blood count, help find the cause and set a safe baseline.
Yes. Testosterone is a Schedule III controlled substance under federal law. That limits refills and means federal and state rules may require specific visit types or an in-person evaluation.
Under current DEA telemedicine flexibilities, extended through December 31, 2026, many patients can. Rules can change, and some states have additional requirements, so the care team will tell you if you need a video visit or an in-person exam.
Each lab reports its own reference range, and your clinician interprets your result against it along with your age and symptoms. A single number is not enough; repeat morning testing and symptoms both matter.
Yes. Added testosterone signals the brain to cut back on the hormones that drive sperm production, which can lead to very low sperm counts. If you want children soon, ask about enclomiphene or other options.
The TRAVERSE trial, a large FDA-required study in men with low testosterone and heart risk factors, did not find a higher rate of major heart events with testosterone gel. It did find more atrial fibrillation, blood clots in the lungs and kidney injury in the testosterone group, so monitoring still matters.
Current evidence has not shown that TRT causes prostate cancer, but it can stimulate an existing one. That is why prostate cancer is ruled out first and PSA is monitored in men at risk.
Libido may improve within a few weeks to a few months. Energy and mood may take a bit longer, and body composition changes take many months.
Not necessarily. Injections are common, but daily gels and other forms are available. Your clinician will help you choose and will teach you the technique if you pick injections.
Typically a few months after starting or changing the dose, then periodically once stable. Tests check testosterone, hematocrit and, for many men, PSA.
Yes, but your levels will likely drop and symptoms may return. Natural production can take months to recover. Talk with your clinician first so you can plan the transition.
No. TRT replaces testosterone to a normal range in men with a diagnosed deficiency, under monitoring. Using high doses to build muscle carries serious health risks and is not offered.
