What is Andarine (S4)?

Andarine (S4) is a partial AR agonist SARM originally developed by GTx. Produces anabolic activity in muscle and bone via partial agonism — lower Emax than full agonists. Notable for retinal AR binding at higher doses. Research tool for partial agonism pharmacology, tissue selectivity studies, and SARM comparative research. Research use only.

Research Applications

Partial AR Agonism

Partial vs full agonist receptor pharmacology — Emax, efficacy, coactivator

Retinal AR Research

Vision disturbance mechanism — AR expression in retinal tissue, S4 binding

SARM Selectivity

Muscle:prostate selectivity ratio, tissue-specific partial agonism

Dose-Response Research

S4 partial agonist curve — Emax plateau, minimal efficacy dose

Comparative SARM Panel

S4 vs Ostarine, LGD-4033, RAD-140 — partial vs full agonist tissue outcomes
