i asked my doctor about this ? he said for someone who lifts weights to an extreme, expample-bodybuilders,powerlifters,football players ect. will always have a higher liver profile than the average person. he told me anyting under 300 (ALT) is fine. this doctor knows his shit. he helps alot of pro athletes. so not some doctor who thinks he knows everything about AAS. just because he 's a doctor. i would get checked for viral hepetitis also............
