TRT: Frequently Asked Questions
Answers to the most common questions about testosterone replacement therapy — safety, cost, timeline, fertility, and how to get started.
Testosterone Replacement Therapy is a prescribed medical treatment that restores testosterone to normal physiological levels (450-700 ng/dL) in men diagnosed with hypogonadism. It is administered through injections, gels, patches, or pellets under ongoing medical supervision.
If you are experiencing persistent fatigue, low libido, difficulty building muscle, weight gain, brain fog, or mood changes, a blood test measuring total and free testosterone can determine if your levels are clinically low (below 300 ng/dL on two separate morning tests).
The TRAVERSE trial (5,246 men) found no increased risk of heart attack, stroke, or prostate cancer with properly monitored TRT. In December 2025, an FDA expert panel recommended removing the prostate cancer warning from TRT labels.
Most men notice energy and mood improvements within 3-6 weeks. Sexual function improves within 3-6 weeks. Body composition changes become visible over 3-6 months. Full optimization typically occurs by 9-12 months.
Yes. Exogenous testosterone suppresses sperm production. This is usually reversible after stopping, but recovery can take 6-12 months. If fertility matters, discuss alternatives like clomiphene or HCG co-therapy with your provider before starting.

The most common side effect is elevated red blood cells (polycythemia), occurring in 5-10% of patients. This is caught with regular CBC monitoring. Other possibilities include acne, fluid retention, and mood changes — all manageable with proper oversight.
TRT is a long-term treatment. Exogenous testosterone suppresses natural production, so stopping typically results in levels dropping back to or below pre-treatment levels. Most men continue indefinitely.
TRT restores testosterone to normal physiological levels (450-700 ng/dL) under medical supervision. Anabolic steroid use involves supraphysiological doses (2-10x normal) without medical oversight. The goals, doses, and risk profiles are fundamentally different.
