Testosterone Therapy for Men: What to Expect
You were tired, flat, and running on nothing. Now you are starting testosterone, or thinking about it. Here is what changes first, what takes longer, what we watch on your labs, and when to call us.
Who testosterone therapy is for
Testosterone therapy is for men with symptoms of low testosterone and labs that confirm it. Symptoms alone are not enough, and one number alone is not enough either.
The common symptoms: low energy, low drive, weaker erections, poor recovery from workouts, losing muscle while gaining belly fat, brain fog, low mood, and a short fuse. But a total testosterone in the normal range does not always settle the question. If your SHBG is high, much of that testosterone is bound up and unavailable, and your free testosterone can sit low while the total looks fine. Our guide Your Labs Came Back Normal. You Still Feel Off. walks through that in detail.
Before your first dose
- Baseline labs, every time. Total and free testosterone, SHBG, a blood count with hematocrit, a metabolic panel, and PSA when your age and history call for it. Results from the last 90 days are accepted.
- An in-person visit in Texas. Testosterone is a controlled substance. Texas requires an in-person evaluation before we can start it, and we prescribe it only to patients physically located in Texas.
- A fertility conversation. Testosterone from outside the body tells your brain to stop signaling the testes, which lowers sperm production, sometimes to zero. If you want children now or later, tell us before you start. Enclomiphene raises your own testosterone without shutting that signal down, and it runs entirely by telehealth.
What changes, and when
Testosterone does not work overnight, and it does not work on everything at the same speed. This is the usual order.
| Timeframe | What you may notice |
|---|---|
| First 3 to 6 weeks | Better drive and interest in sex. Improved mood, less irritability, more energy through the afternoon. |
| 6 to 12 weeks | Clearer thinking and more motivation. Erections often start improving here, and can keep improving for several months. |
| 3 to 6 months | Changes in body composition: more muscle, less fat around the middle, better strength and recovery when paired with training. |
| 6 months and beyond | Bone density starts improving. Red blood cell changes build up over the first year, which is why hematocrit gets checked. Body composition keeps improving for a year or more. |
If nothing has changed after three to six months on a dose that should be working, that is a reason to look harder, not to keep waiting. Sometimes it is the dose or the injection schedule. Sometimes it is a second problem, like thyroid, iron, or sleep apnea, that testosterone was never going to fix.
How we follow you
- Three-week check-in. How you feel, how you are tolerating it, and any side effects. No labs needed.
- Three-month check-in. Same questions with more time on board. Your dose or injection schedule gets adjusted based on your symptoms.
- Labs every six months. Testosterone levels, hematocrit, and PSA when it applies. Sooner if your symptoms change or you ask.
We adjust to how you feel, not to a single number. And we do not set a dose and forget it. If your provider has had you on the same dose for two years without asking how you feel, that is not how care works here.
About your dose. Your dose and injection schedule are personal to you and come from your individual care plan, not from this page. Never change your dose, skip around your schedule, or stop on your own. Message us first.
Side effects to know about
- Acne or oily skin, often on the back and shoulders
- Mild fluid retention
- Breast tenderness
- Smaller, softer testes
- Lower sperm count
- A rising hematocrit, meaning thicker blood. You usually cannot feel it, which is why we check it.
- Changes in PSA
- Worsening sleep apnea, so tell us if snoring or daytime sleepiness gets worse
Most of these respond to a change in dose or schedule. We try those adjustments first and add other medications only when they are needed.
- Headaches, dizziness, or a red, flushed face that keeps coming back
- A new lump or ongoing pain in the breast tissue
- Trouble urinating or a weaker stream
- Swelling in your ankles or legs that does not go away
- Redness, heat, or swelling at an injection site that is spreading
Call 911 for chest pain, trouble breathing, sudden weakness or numbness on one side, slurred speech, or a painful, swollen leg.
A few practical things
- Draw your monitoring labs at the time in your injection cycle we tell you, so the numbers mean something.
- Store your medication at room temperature, away from heat and light.
- Our self-injection guide covers technique, sites, and safe needle disposal.
- Strength training, sleep, and protein make testosterone work better. They are part of the treatment.
