TRT stands for testosterone replacement therapy, which is a type of hormone replacement therapy designed to restore healthy testosterone levels in someone who suffers from low T. Testosterone is the primary androgen in males and has an impact on many biological processes that are necessary for health and longevity. TRT is primarily used to treat low testosterone levels, which can occur with age or as a result of a medical condition. It can be administered in the form of injections, pellets, patches, gels, oral medications, or topical creams. TRT can improve the signs and symptoms of low testosterone in men, such as low energy levels, decreased muscle mass, and reduced sexual performance. However, TRT is not a fountain of youth and does not treat the underlying cause of low testosterone. TRT has potential benefits and risks, and it is important to consult with a healthcare provider to determine if it is right for you.
