What this is
Regarded by users as the most 'wet' and strongest SARM — closer to traditional AAS effect profile. Multiple published case reports of drug-induced liver injury. Radius Health halted clinical development. Aggressive marketing as 'legal steroid' despite clear illicit status.
Mechanism
Strong non-steroidal SARM; high anabolic activity in muscle with reduced prostate effects in preclinical; originally developed by Radius Health for breast cancer and now abandoned
Dose & route
Typical illicit: 10-20 mg/day PO
