SUSTANON

Sustanon is a well-established testosterone replacement therapy used to treat male hypogonadism, restoring serum testosterone to eugonadal range. Clinical evidence supports improvements in sexual function, bone density, lean body mass, and depressive symptoms with testosterone replacement. A large randomized trial showed no increased risk of myocardial infarction or stroke even in high-risk patients, though cardiovascular safety remains debated. An avian model demonstrated dose-independent hypertrophy and satellite cell proliferation in oxidative muscle fibers. Evidence for performance enhancement beyond TRT is largely extrapolated from general testosterone physiology studies rather than Sustanon-specific trials. Monitoring of hematocrit, PSA, and testosterone levels is required during therapy.
