Research applications
Andarine (S-4, GTX-007) is the prototypical aryl-propionamide SARM from Ligand's bicalutamide-derived series, studied for dissociated androgen signaling. Its dose-dependent retinal-conflict findings in early human cohorts made it the standard example of off-target tissue exposure in SARM selectivity research.
