Clomigen is an anti-estrogen medication containing Clomiphene Citrate, commonly used in post-cycle therapy (PCT) to help restore natural testosterone production after anabolic steroid use. By blocking estrogen receptors, Clomigen helps prevent estrogen-related side effects like gynecomastia, while promoting the body's natural production of testosterone. It is also used to improve fertility in men by stimulating the production of hormones that boost sperm count. Clomigen is widely used by athletes and bodybuilders to maintain hormonal balance and protect gains following a steroid cycle.
