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

The high affinity and specificity of S4 (Andarine), a non-steroidal selective androgen receptor modulator (SARM), for androgen receptors (ARs) is well recognized. It demonstrates tissue-selective activity, lowering systemic off-target interactions and modifying androgenic signaling pathways. This substance is mostly metabolized in the liver by oxidation and glucuronidation, and it is eliminated by renal and biliary excretion.
