Starting testosterone as a trans man involves a medical consultation, choosing a delivery method, and then monitoring your levels over the first several months as your body begins to change. The process is more accessible than it used to be, with many clinics now offering hormone therapy through an informed consent model that can get you started in a single visit. Here’s what the process actually looks like from start to finish.
Two Paths to Getting a Prescription
There are two main models for starting testosterone, and which one you encounter depends on your provider. The older model requires a referral letter from a mental health professional before a prescribing doctor will write your prescription. This can add weeks or months to the process, depending on wait times and the number of sessions your therapist requires.
The informed consent model skips that step. Under this approach, your medical provider assesses your understanding of the risks, benefits, alternatives, and unknowns of testosterone therapy, and can prescribe hormones without a separate mental health referral. Many large-volume transgender care providers have used this model for years. Planned Parenthood locations, LGBTQ health centers, and some telehealth services commonly operate this way. If speed matters to you, searching for “informed consent HRT clinic” in your area is the fastest route.
Regardless of which model you use, your first appointment will include a medical history review and baseline blood work. Providers check your existing hormone levels, liver function, cholesterol, and blood cell counts before prescribing. This gives them a starting point to compare against later.
Choosing a Delivery Method
Most trans men start with injections, but you have options. Each method delivers the same hormone with the same long-term effects. The differences come down to convenience, consistency, and personal preference.
- Injections (cypionate or enanthate): The most common choice. Typically given weekly to maintain even blood levels, though some providers prescribe every two weeks. You’ll learn to self-inject at home, usually into the thigh or glute. Injections tend to be the most affordable option.
- Topical gel: Applied to the skin daily, usually on the upper arms or shoulders. Gels provide steadier day-to-day hormone levels than injections but require daily application and care to avoid skin-to-skin transfer to others.
- Subcutaneous pellets: Tiny pellets inserted under the skin every few months during a quick office visit. Pellets are only used after you’ve been on a stable dose of another form of testosterone, so they’re not a first-line option.
Most people start with injections because they’re affordable, well-studied, and only require attention once a week. If needles are a dealbreaker, gel is a solid alternative.
What It Costs
Generic testosterone cypionate is one of the more affordable prescription medications. Without insurance, a 10ml vial at 200mg/ml (which can last several months depending on your dose) runs roughly $50 to $185 at retail, though discount programs can bring it down to around $49 or less. A single 1ml vial costs about $28 to $51. Syringes and alcohol swabs add a few dollars per month.
If you have insurance, many plans cover testosterone for gender-affirming care, though coverage varies widely by state and insurer. Telehealth services often charge a separate consultation fee on top of the medication cost. Factor in blood work every few months as well, which insurance typically covers as routine lab monitoring.
Starting Doses and Early Blood Work
Providers typically start you on a lower dose and increase gradually. For adults, a common starting range for injectable testosterone is 50 to 100mg per week (or the equivalent every two weeks). The goal is to bring your total testosterone into the typical male range of 300 to 1,000 ng/dL, then hold it there.
You’ll have follow-up blood work one to three months after starting, then roughly every six months. These labs check whether your testosterone levels are in range and monitor for side effects. Your provider will adjust your dose based on both your numbers and how you’re feeling. It often takes a few adjustments over the first six months to find the right dose for your body.
What Changes to Expect and When
Testosterone works gradually. Some changes show up within weeks, while others take years to fully develop. Here’s a general timeline, though individual variation is significant.
In the first one to three months, most people notice skin becoming oilier, increased body odor, changes in libido, and the beginning of lower body fat redistribution. Periods typically stop within the first six months, sometimes sooner. Emotional shifts are common early on as your body adjusts.
Voice deepening usually starts between three and twelve months. It happens unevenly, with your voice cracking or feeling strained before settling into a lower register. Full deepening can take one to two years. Facial hair growth is one of the slowest changes, often starting as peach fuzz on the upper lip around six months to a year, with fuller growth developing over several years. Genetics play a large role in how much facial and body hair you ultimately get.
Body fat will gradually shift from a typically feminine pattern (hips and thighs) toward a more masculine pattern (abdomen). Muscle mass increases, especially if you’re physically active. These changes develop steadily over the first two to five years.
Permanent vs. Reversible Changes
Not all changes reverse if you stop testosterone. Voice deepening is permanent. Facial and body hair growth is permanent, though hair may thin somewhat. Clitoral growth (bottom growth) is permanent. On the other hand, changes to muscle mass, fat distribution, and skin oiliness will gradually revert if you discontinue therapy. Knowing which changes are irreversible matters, especially if you’re uncertain about long-term use.
Side Effects and Monitoring
The most closely watched side effect is a condition where your body produces too many red blood cells, thickening your blood. This happens because testosterone stimulates red blood cell production. Providers monitor this through a measurement called hematocrit in your regular blood work. Levels above 50% are flagged as potentially concerning, and levels above 54% typically prompt a dose reduction, a temporary pause, or a blood draw to bring levels down. This is the main reason consistent lab monitoring matters.
Other common side effects include acne (often worst in the first year or two), hair thinning or male-pattern baldness (depending on your genetics), increased appetite, and changes in cholesterol levels. Vaginal dryness and atrophy are common and can cause discomfort, but topical treatments are available if needed.
Mood changes vary widely. Some people feel more emotionally stable on testosterone, while others experience irritability, especially when hormone levels fluctuate between doses. Weekly injections tend to produce fewer mood swings than biweekly dosing because the hormone level stays more consistent.
Fertility Considerations
Testosterone lowers fertility over time, but it is not a reliable form of birth control. Ovulation can still occur while you’re on testosterone, meaning pregnancy is possible if you’re having sex that could result in conception. If you think you might want biological children in the future, talk to your provider about fertility preservation options like egg freezing before starting or early in your treatment. The longer you’re on testosterone, the less certain it becomes that fertility will fully return after stopping.
Practical Tips for Getting Started
If you’re ready to move forward, a few things will make the process smoother. Start by identifying providers in your area who prescribe gender-affirming hormones. Planned Parenthood, university-affiliated gender clinics, and LGBTQ health centers are reliable places to look. Telehealth services have expanded access significantly for people in areas without local providers.
At your first appointment, bring a list of any current medications and your medical history. Be prepared to discuss your goals for transition openly, as this helps your provider tailor your treatment. Ask about what form of testosterone they recommend and why, and get clear instructions on self-injection technique if you go the injection route. Most clinics will walk you through your first injection in office.
Keep a simple log of your injection dates, any side effects, and changes you notice. This is genuinely useful at follow-up appointments when your provider asks how things are going. Changes happen slowly enough that it’s easy to forget what shifted when. Photos at regular intervals can also help you track physical changes that are hard to notice day to day.
