Andarine is a brand of selective androgen receptor modulator (SARM). The full name is S-40503 but called S-4 for short. The product was manufactured by Kaken Pharmaceuticals, a Japanese pharmaceutical company, for the treatment of osteoporosis.
Andarine binds fittingly to the androgen receptors of our bone and muscles. It is unimpressive, though, when it comes to building pounds upon pounds of muscle as Trenbolone would, but it is fantastic on losing fat. How is it able to help with fat loss? It does help with fat loss because it is the more androgenic and least anabolic of the SARMs in the market.
Fat oxidation is triggered when androgenic hormones or SARM binds with the androgen receptors in your adipose tissue or fat (yes, our fat contain androgen receptors too).
Andarine is exceptional at strengthening, preserving and building bone mass. It is selective and exhibits no apparent prostate action. This brand of SARMs is a weak muscle tissue builder in lower doses, but at higher doses, it builds lean hard muscle tissues with results comparable to that of Anavar and Winstrol without androgenic side effects.
