S4 Powder (Andarine)

Brief Intro

S4 Powder (Andarine) is a selective androgen receptor modulator (SARM) developed by GTX, Inc., designed to promote muscle growth and bone health by selectively binding to androgen receptors in these tissues. Unlike traditional steroids, Andarine offers anabolic benefits with fewer side effects in other organs. It has been investigated for conditions such as muscle wasting, osteoporosis, and benign prostatic hyperplasia (BPH), though clinical development has been discontinued in favor of related compounds. This powder is intended strictly for scientific research and analytical purposes and is not for human consumption124.

What are SARMs?

SARMs are Selective Androgen Receptor Modulators. In simple terms, these substances can tell your cells to produce more muscle mass or break down more fat, for example. Each SARM has a different effect, allowing you to achieve aesthetic and physical goals in a very targeted way. And all that without suffering unpleasant side effects such as hair loss, acne and liver damage.
