In vitro studies of Ostarine binding to androgen receptors (AR) showed the highest affinity for SARMs with a Ki value of 3.8nM. Ostarine acted on CV-1 cells cotransfected with human AR expression vector, luciferase reporter vector and β-galactosidase control vector when the concentration of Ostarine Chemicalbook was 10nM to regulate AR transcription activity.
