Testosterone replacement therapy (TRT) is used to address conditions associated with symptoms of low testosterone levels. It involves replacing the body's insufficient testosterone with synthetic forms, typically through injections like testosterone cypionate or gels like generic AndroGel. Testosterone support treatments, on the other hand, aim to enhance or support natural testosterone production rather than replace it. These treatments might include lifestyle changes, dietary supplements, or medications like Clomid or sermorelin that help optimize the body’s own testosterone levels. They are often used for individuals with lower but not critically low testosterone levels or those looking to improve overall hormone balance without full replacement.
