Clomiphene is one of the most common pharmacological drugs in the first-aid kit of bodybuilders on steroids. Clomid is used by athletes on the course of anabolic steroids to eliminate the side effects associated with the partial conversion of steroids to estrogen (female sex hormone), and to stimulate the internal production of testosterone after a course of steroids (at PCT), which is suppressed when taking steroids. It possesses strong anti-estrogenic properties, which can be useful in medicine and bodybuilding for athletes using steroids.
