Oral selective androgen receptor modulators (SARMs) are investigational agents. Studied since 1998, they are still very much in the infancy of their development and marketing. SARMs may be able to provide the benefits of increased muscle mass and bone density, and fat loss that testosterone and other traditional anabolic/androgenicsteroids provide but without the unwanted side effects (prostatic enlargement). SARMs are not intended to be a form of testosterone replacement therapy. So, why am I talking about them?
