S-4 (Stanavar) is a selective androgen receptor modulator (SARM), and similar to other members of the SARM group it was originally developed as a way to treat diseases or conditions associated with muscle and bone wasting. S-4 has been shown to bind the androgen receptor very strongly, and in addition to selectively binding the androgen receptors in muscle and bone it has the added benefit of binding the androgen receptors in adipose tissue, or fat, which triggers fat oxidation or utilisation.

S-4 is strongly anabolic, very anti-catabolic, not significantly suppressive of your own testosterone production or the hypothalamus-pituitary-testicular axis, with no unwanted androgenic side effects.

S-4 is very effective in improving lean muscle mass and strength gains, and body fat reduction, improved recovery and also maintaining size during a cutting cycle.
