Selective Estrogen Receptor Modulator

Selective Estrogen Receptor Modulators (SERMs) are compounds used in bodybuilding to manage estrogen levels, helping to prevent side effects like gynecomastia while allowing some estrogenic benefits for muscle growth and recovery. They work by binding to estrogen receptors in specific tissues, blocking estrogen's effects in areas like breast tissue while promoting positive effects in others, such as muscle and bone.
