if you asked experienced body builders they would tell you they don't even know what a SARM is lol. Ask any mr Olympia or Arnold classic winner over the last 15 years and I'll bet they'll say they don't even know what SARMs are yet alone ever taken one
btw - GW (cardarine) is NOT a Sarm . its been around 20 years before sarms were ever invented. its a PPAR agonist
