Sarm 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 action to create their results, whereas anabolic steroids are not selective and therefore create changes to many hormones, sexual functions and other important functions in the body.
Sarmsamerica targets different Androgen Receptors in the body and therefore each yield different positive effects on the body.
