I’d have to dig for it but I know there has been bloods for IGF on here and other boards using SARMS. Just like anything else, you gotta make sure your source is good. I personally choose to forego SARMS because there just isn’t enough research on long term use and their different effects on the body. They do give results though and can be a good alternative if you’re willing to take the risk. For me? Yeah, I’ll stick to the tried and true methods.
