S-23 – High-Purity Selective Androgen Receptor Modulator – 90 Capsules
S-23 is a potent selective androgen receptor modulator (SARM) studied in advanced research protocols focused on androgenic selectivity, body composition, and tissue development. Recognised for its strong receptor binding affinity, S-23 is often selected for conditioning and definition-focused studies and is frequently compared to compounds such as S4 (Andarine) for its intensity and activity profile.
Its strength and reliability make it a preferred choice in performance-driven models, particularly those examining non-steroidal anabolic responses in controlled environments.

Research Highlights
-
S-23 has been shown in preclinical trials to induce dose-dependent increases in lean muscle mass with minimal off-target effects, making it a strong candidate for selective anabolic research.
-
It is often stacked with compounds such as RAD-140, MK-677, or LGD-4033 in research models assessing synergistic performance outcomes.
-
S-23 is also explored in hormonal suppression studies, as it may influence LH and FSH pathways in dose-responsive experiments.
