FAQ
TRT Frequently Asked Questions
Everything men need to know about testosterone replacement therapy — from qualifying levels and safety to protocols and provider selection.
Symptoms & Diagnosis
What are the symptoms of low testosterone?
Common symptoms include persistent fatigue, reduced libido, erectile dysfunction, brain fog, difficulty concentrating, loss of muscle mass, increased body fat (especially abdominal), mood changes (irritability, depression), poor sleep quality, and decreased motivation. Most men experience multiple symptoms simultaneously.
At what age do testosterone levels start declining?
Testosterone levels begin declining around age 30, dropping approximately 1-2% per year. By age 45-50, many men have testosterone levels 20-40% below their peak. However, lifestyle factors (sleep, stress, diet, exercise) can accelerate or slow this decline.
What testosterone level qualifies for TRT?
Most providers consider total testosterone below 300 ng/dL as definitively low. Many progressive clinics will treat at 300-450 ng/dL if symptoms are present and free testosterone is suboptimal. The key is correlating labs with symptoms — numbers alone don't tell the full story.
Safety & Side Effects
Is TRT safe long-term?
When properly monitored with regular bloodwork, TRT has a strong long-term safety profile. Studies show no increased cardiovascular risk and potential cardiovascular benefits. Key monitoring includes hematocrit, PSA, estradiol, and lipid panel every 3-6 months.
Will TRT affect my fertility?
Exogenous testosterone suppresses sperm production. If fertility is a concern, discuss HCG with your provider — it maintains testicular function alongside TRT. Providers like FYRE Body include HCG as a standard option. Fertility typically returns within 6-12 months of stopping TRT.
What are TRT side effects?
Common manageable side effects include elevated hematocrit (blood donation helps), acne (usually temporary), water retention, and potential estrogen elevation. These are managed through protocol adjustments, AI use when needed, and regular monitoring. Serious side effects are rare with proper oversight.
What is the difference between TRT and steroids?
TRT replaces testosterone to normal levels (600-1000 ng/dL), prescribed by a physician with monitoring. Steroid abuse involves supraphysiological doses (3-10x normal) without oversight. TRT is legal, prescribed, and health-optimizing.
Protocols & Treatment
What blood tests do I need for TRT?
Initial labs: Total Testosterone, Free Testosterone, SHBG, Estradiol (sensitive), LH, FSH, CBC, CMP, Lipid Panel, PSA, Thyroid Panel. Ongoing monitoring (every 3-6 months): Total/Free T, Estradiol, Hematocrit, PSA, Lipids.
How is testosterone administered?
Most online TRT uses intramuscular or subcutaneous injections of testosterone cypionate, typically 1-2x per week. Some clinics offer testosterone cream/gel as an alternative. Injections provide the most stable blood levels and best cost efficiency.
How quickly does TRT work?
Energy and mood: 2-4 weeks. Libido: 3-6 weeks. Body composition: 8-12 weeks. Full optimization: 3-6 months. Patience and consistent adherence are key.
