IGF-1 is very interesting for me. I can't seem to decide if LR3 is worth the hype, from my reading and understanding LR3 is too big to attach to in the muscles, I believe what its supposed to attach to is a binding protein.. I have been reading and it seems that LR3 is just too big a molecule, and the only real way to get size from IGF-1 is to inject DES Immediately PWO. DES can actually attach. Although I read conflicting information, so I'm really confused.
