Compounds known as Selective Androgen Receptors are an alternative to banned anabolic agents. They show similar properties to anabolic preparations, however, with reduced androgenic properties.
SARM supplements are used to improve athletic performance, increase muscle mass, reduce body fat, and bone mineralization. Because of their anabolic properties and ability to stimulate androgen receptors in muscles and bones, they are eagerly used by athletes. Popular SARMs include: MK-677, YK-11, S4, Rad-140, Ostarine, S23, GW-501516, SR-9009, LGD-4033.
