Andarine(S4) Description

Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands. They are intended to have the same kind of effects as androgenic drugs like anabolic steroids but be much more selective in their action, allowing them to be used for many more clinical indications than the relatively limited legitimate uses that anabolic steroids are currently approved for.

S-4 is an experimental or investigation-stage proprietary SARM research chemical developed by GTx Inc for treatment of benign prostatic hypertrophy, muscle wasting, and osteoporosis. S-4 is considered a partial agonist of the androgen receptors in target tissue. S-4 has less pronounced anabolic and androgenic compared to other SARMs. In trials treating BPH induced in animal models, S-4 reduced prostate weight as effectively as finasteride and without producing any reduction in muscle mass or other side effects common with androgen receptor binding compounds. Gao et al suggest that by binding to androgen receptors, S-4 prevents DHT from binding and activating, but bypasses the expected anti-androgenic effects that would occur from occupying androgen receptors due to the fact that S-4 itself is a partial agonist of androgen receptors. S-4 has also been shown to prevent bone loss, reduce body fat, and improve muscle strength and body composition in orchidectomized and ovariectomized rats.
