S4 (Andarine) is a research chemical belonging to the group of SARMS, the selective androgen receptor modulators. It can bind to the androgen receptors, as well as anabolic steroids. The difference is, however, that the anabolic and androgenic processes are not caused by the androgenic per se, but by the SARM per se.
In the US, Andarine is used in medicine to counter prostate growth, to fight muscular dystrophy, and to relieve osteoporosis as it favors the growth of muscular tissue of skeletal muscle rather than the heart muscle.
