Blood tests are used to track hormone levels, blood counts, and prostate markers. It is also necessary to understand that testosterone therapy carries risks and limits. These effects can lead to higher quality of life, even if the physical body looks mostly the same at first glance. Another important point is that testosterone therapy affects more than just appearance. Some of our patients have even reported a visual difference in muscle fullness or dryness in a matter of hours. Crazy Bulk manufactures natural and FDA-approved compounds that mimic the anabolic effects of steroids but without deleterious side effects. However, some steroids are FDA-approved in medicine, so doctors can prescribe certain compounds (like testosterone) within the confines of the law. In our experience, there is little you can do to reduce visceral fat once it has accumulated to this level. What matters most are the changes in health, strength, and well-being that can be measured in the body. By combining all of these tools, doctors create a complete "before and after" picture of therapy that is accurate, safe, and medically meaningful. Testosterone therapy can influence mood, energy, and mental clarity. Although not always visible in pictures, sexual health is an important part of before-and-after progress. While pictures may show more visible muscles or a slimmer waist, body composition data gives exact numbers that prove whether those changes are truly happening. Blood tests are usually done before therapy starts, then several times during the first year, and then at least once or twice a year after that. For most people, the full effect on bone strength, muscle growth, and fat reduction may take one to two years. The first key point to understand is that testosterone therapy does not produce dramatic overnight results. In men who still wish to have children, semen analysis may also be needed, since testosterone therapy can lower sperm production. Testosterone therapy can increase lean muscle mass and decrease fat, especially in the belly area. Matthew was always laser-focused on his health, achieving a master’s degree in exercise physiology and working as a strength and conditioning coach. Jonathan struggled to build muscle for years, despite packing in protein and sticking to a rigorous fitness routine. He is now committed to optimizing other areas of his health so that he can age better. For Dave, starting TRT was like taking a blindfold off. Now six months on TRT, he’s gearing up to compete again.
