Clomid (clomiphene) was one of the original drugs used in post-cycle-therapy to stave off gynocomastia and raise the body’s natural testosterone levels.This
drug is not a steroid; it is a synthetic estrogen used as a fertility drug. In men it can work as both an anti-estrogen, and a gonadotropic stimulant. Male steroid users find that it can work quite well to prevent gynecomastia while taking
steroids that aromatise. It also is used to bring the body's natural testosterone levels back up to normal after a steroid cycle.
