SARMs are non-steroidal compounds that can bind to androgen receptors and exert tissue-specific effects. A hypothetical SARM, for example, might block (or only weakly activate) androgen receptors in the prostate while activating receptors in bone and/or skeletal muscle.
Ideally, SARMs would provide the benefits of anabolic-androgenic steroids (ASS) without the drawbacks (I.E. virilisation, acne, prostate disease, alteration of blood lipids). Although there are no current drugs available on the market, SARMs are an active field of pharmaceutical research.
In the near future SARMs mar be used to treat osteoporosis, muscle-wasting conditions (AIDS, sarcopenia, cachexia, post burn/injury catabolism) and prostate disease. Male contraception is another potential application.
