S4

S4 (Andarine) is a Selective Androgen Receptor Modulator (SARM) recognized for its strong anabolic properties and versatile benefits in both muscle building and fat reduction. Originally developed with medical applications in mind, Andarine quickly gained popularity in the fitness community for its ability to preserve lean muscle mass during calorie restriction while simultaneously promoting new muscle growth.

One of the standout features of S4 is its ability to support fat loss without compromising strength or size. By binding selectively to androgen receptors in muscle and bone tissue, it enhances strength, endurance, and muscle density—without the water retention, bloating, or androgenic side effects commonly associated with anabolic steroids. Users often report a harder, leaner physique, making it particularly well-suited for cutting and recomposition phases.

Although a relatively newer addition to the mainstream SARM market, Andarine has built a solid reputation for delivering consistent and effective results. Its unique ability to balance muscle preservation, growth, and fat metabolism has made it a trusted option for athletes and bodybuilders aiming for performance enhancement and a more defined, athletic look.
