Testosterone FDA-Approved
Forms: Injectable (cypionate/enanthate), topical gels/creams, pellets
Category: Hormone Therapies — Testosterone Replacement Therapy (TRT)
How it works. Testosterone is the primary androgen hormone, responsible for muscle mass and strength, bone density, red blood cell production, libido and sexual function, mood, and energy. Levels decline gradually with age, and can fall further with obesity, metabolic disease, sleep apnea, opioid use, and pituitary or testicular conditions. Testosterone replacement therapy restores circulating levels to a healthy physiologic range—it does not create supraphysiologic bodybuilder levels, and a responsible program never should.
Why a physician prescribes it. TRT is FDA-approved for clinically documented hypogonadism—low testosterone confirmed on properly timed morning labs, drawn more than once, in a patient with consistent symptoms: low libido, erectile changes, fatigue, loss of muscle, mood changes. That two-part requirement matters. A low number without symptoms is not an indication, and symptoms without confirmed low labs deserve a workup for other causes first—thyroid, sleep, depression, medications. When the diagnosis is real, the benefits are well documented: improved sexual function, energy, body composition, bone density, and often mood.
What to know before starting. The monitoring is not optional. Hematocrit rises on TRT and must be tracked (erythrocytosis increases clot risk); PSA and prostate status are monitored—TRT does not cause prostate cancer, but it can accelerate an existing one; fertility is a major conversation, because exogenous testosterone suppresses sperm production, which is where HCG or other preserving strategies enter the discussion for men who want children. The landmark TRAVERSE trial (2023) provided reassurance that TRT in properly diagnosed men did not increase major cardiovascular events, while flagging small increases in atrial fibrillation, venous clots, and acute kidney injury. Sleep apnea, severe heart failure, and untreated polycythemia are cautions. Labs at baseline, labs on schedule, dose to the patient—not to a number on a forum.
