SARMs stands for Selective Androgen Receptor Modulators. They are a group of compounds that selectively target androgen receptors in muscle, bone, connective tissue, body fat, brain tissue and nerve, without the negative side effects that anabolic steroids produce. This is due to SARMs being selective in nature, whereas anabolic steroids
Each Sarm targets different Androgen Receptors in the body and therefore each one yields different effects on the body.
Sarms are NOT steroids nor are they hormones.
