Getting testosterone replacement therapy (TRT) requires a confirmed diagnosis of low testosterone, which means blood work showing levels below 300 ng/dL combined with symptoms like low energy, reduced sex drive, or difficulty with concentration. You can’t walk into a pharmacy and pick it up. TRT is a controlled substance, so you’ll need a prescription from a licensed provider after meeting specific clinical criteria.
What Qualifies You for TRT
The American Urological Association sets the diagnostic bar at a total testosterone level below 300 ng/dL. But a single low reading isn’t enough. You need two separate blood draws, both taken in the early morning (typically before 10 a.m.), because testosterone levels naturally peak after waking and drop throughout the day. A late-afternoon test could show a misleadingly low number.
Numbers alone won’t get you a prescription either. Providers look for a combination of low levels and real symptoms. The recognized signs fall into three categories:
- Physical: persistent fatigue, reduced endurance, loss of lean muscle mass, increased body fat, loss of body hair, reduced beard growth
- Sexual: low sex drive, weaker erections
- Cognitive: depressive symptoms, poor concentration, brain fog, reduced motivation, irritability
If your testosterone comes back at 280 ng/dL but you feel fine and have no complaints, most responsible providers won’t prescribe TRT. The diagnosis requires both the lab result and the clinical picture.
The Blood Work You’ll Need
Your initial panel will include total testosterone, free testosterone, and a protein called sex hormone-binding globulin (SHBG) that affects how much testosterone your body can actually use. Some men have a normal total testosterone level but low free testosterone because too much of it is bound up by SHBG, so both numbers matter.
Most providers also order additional tests before starting treatment. These typically include a complete blood count (to check your red blood cell concentration), a prostate screening test, and basic metabolic markers. The red blood cell check is particularly important because TRT can thicken your blood over time, and your provider needs a baseline to monitor against. Expect to pay $100 to $300 for initial lab work if you’re covering it out of pocket.
Where to Get a Prescription
You have several options, each with trade-offs.
Primary Care Doctor
Your regular doctor can order the blood work and write the prescription. This is the simplest starting point if you already have an established relationship. The downside is that some PCPs aren’t deeply familiar with hormone optimization and may default to whatever your insurance covers, which is often a topical gel rather than injections.
Endocrinologist or Urologist
Specialists offer more targeted expertise. Endocrinologists deal with hormonal systems broadly and are often well suited to managing TRT, especially if there’s an underlying cause to investigate. Urologists handle male reproductive health but can be hit or miss. Some patients report that urologists focus narrowly on total testosterone and are less interested in treating borderline cases or investigating free testosterone levels. If you go the specialist route, an endocrinologist is often the better fit for hormone management.
TRT and Hormone Clinics
Specialty clinics, both in-person and online, have become a popular option. These clinics focus exclusively on hormone therapy, which means shorter wait times and providers who deal with TRT protocols daily. Many handle everything from blood work to medication delivery. The trade-off is cost: most operate outside insurance, so you’ll pay out of pocket for consultations and ongoing monitoring.
Telehealth Providers
Online TRT clinics have grown significantly in recent years. Through the end of 2026, federal rules allow providers to prescribe controlled substances like testosterone via telehealth without requiring an in-person visit first. This means you can complete a video consultation, get lab orders sent to a local draw site, and have your prescription shipped to your door. These flexibilities are temporary extensions that have been renewed yearly, so the rules could change, but for now telehealth remains a fully legal path to TRT.
Treatment Options and What They Cost
Once you have a prescription, you’ll choose a delivery method. The right one depends on your budget, lifestyle, and how much you want to think about your treatment on a daily basis.
Injections are the most common and most affordable option, running $30 to $150 per month. Most modern protocols use weekly or twice-weekly self-injections with a small needle just under the skin. Levels are easy to adjust, and there’s no risk of accidentally transferring testosterone to a partner or child through skin contact. The learning curve for self-injection is minimal, and most people get comfortable within the first few doses.
Gels and creams are applied daily to the skin, typically on the shoulders, upper arms, or inner thighs. They provide a steady daily release without needles, which appeals to some people. The downsides are meaningful, though: they cost $200 to $500 per month, you need to avoid skin-to-skin contact with others for several hours after application, and absorption varies depending on your skin and activity level.
Pellets are small implants inserted under the skin of the hip during a quick office procedure. They release testosterone steadily over three to six months, making them the most hands-off option. You only need two to four appointments per year. The cost is $500 to $1,500 per insertion cycle, and the procedure requires a small incision with a single stitch.
None of these prices typically include consultations or ongoing lab work, which can add $100 to $500 depending on your provider and how often you’re seen.
What Happens After You Start
TRT isn’t a set-it-and-forget-it treatment. Your provider will check your testosterone levels two to four weeks after starting, depending on the delivery method, to see if your dose needs adjusting. After that, follow-up blood work happens every six to twelve months for as long as you’re on therapy.
The most important thing your provider monitors is your red blood cell concentration (hematocrit). TRT stimulates red blood cell production, and if levels climb too high, your blood becomes thicker and harder to pump, which raises cardiovascular risk. The clinical cutoff is a hematocrit above 54%, and if yours creeps toward that number, your provider will adjust your dose or have you donate blood to bring it down.
You should also expect prostate screening at regular intervals. TRT doesn’t cause prostate cancer, but it can accelerate the growth of an existing prostate issue that hasn’t been detected yet. If you have a history of prostate disease, your provider will want to discuss that before prescribing.
Sleep apnea is another condition that can worsen on TRT. If you develop loud snoring, gasping during sleep, or new daytime sleepiness after starting treatment, bring it up at your next visit.
Insurance vs. Out of Pocket
Insurance coverage for TRT varies widely. Many plans cover injectable testosterone with a confirmed diagnosis, but some restrict coverage to gels or require prior authorization. If your total testosterone is above 300 ng/dL but your free testosterone is low, some insurers won’t cover treatment at all because you don’t meet their threshold.
Out of pocket, the most budget-friendly path is injectable testosterone through a traditional provider or telehealth clinic. Between medication ($30 to $150 monthly), initial labs ($100 to $300), and follow-up visits ($50 to $200 each, a few times per year), you’re looking at roughly $600 to $2,500 annually depending on your provider and protocol. Gels, creams, and pellets raise that number significantly.
Steps to Get Started
The practical path is straightforward. Schedule a morning blood draw through your doctor, a lab company, or an online TRT provider. If your total testosterone comes back below 300 ng/dL and you have symptoms, get the second confirmatory draw. Bring both results to your provider (or let your telehealth clinic handle the interpretation), discuss your symptoms, and choose a treatment method together. Most people have a prescription in hand within two to four weeks of their first blood draw, faster through online clinics that streamline the process.
