Introduction of S-4

Andarine (S-4) is one of SARMS in the market. Like all SARMs, Andarine is a selective androgen receptor modulator. It’s full name is S-40503, and it quickly became known as S-4, while stronger versions have been dubbed Andarine. Andarine was developed by the Japanese pharmaceutical company, Kaken Pharmaceuticals, and it was aimed at treating osteoporosis. S-4 is able to competitively block binding of dihydrotesarms s-4 andarine cas 401900-40-1stosterone to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.
