S4 (Andarine), (25mg/capsule) 60 Capsules

S4 (Andarine) is a non-steroidal selective androgen receptor modulator (SARM) known for its high affinity and specificity for androgen receptors (ARs). It exhibits tissue-selective activation, modulating androgenic signaling pathways while reducing systemic off-target interactions. This compound undergoes hepatic metabolism primarily through oxidation and glucuronidation, with clearance occurring via renal and biliary excretion.
