S4 | Andarine RESEARCH CHEMICAL 

CONCENTRATION: 50MG OF S4 | Andarine PER ML , 3OML BOTTLE 

S4, commonly known as Andarine, emerges as a notable entity within the realm of selective androgen receptor modulators (SARMs). Its unique capacity to selectively interact with androgen receptors presents opportunities for targeted anabolic effects.

Structural Composition: S4 (Andarine) is represented chemically as (2S)-3-(4-acetamido-phenoxy)-2-hydroxy-2-methyl-N-(4-nitro-3-trifluoromethyl-phenyl)-propionamide. Its structural configuration encompasses a trifluoromethylphenyl group, contributing to its specific affinity for androgen receptors.

Mechanism of Androgen Receptor Interaction: Operating as a selective androgen receptor modulator, S4 engages with androgen receptors in a manner that is tissue-selective. Upon binding, it induces conformational changes in the androgen receptor's ligand-binding domain, triggering interactions with co-regulatory proteins. This orchestrated series of events results in selective anabolic effects in target tissues, such as skeletal muscle, while minimizing androgenic effects in non-target tissues
