In the end, when it comes to taking PEDs, is it all about agonizing one's IGF levels for growth? More so IGF-1 levels? I have seen studies mentioning this and gurus too. Just wondering. I know there are other hormones in play but it seems like taking anything with raise IGF levels in the end.
Yes, AAS increase IGF-1 but this is a very complex question but I think the simple answer is that AAS have more properties that facilitate muscle growth than simply raising IGF-1 alone.
I would love to hear a better answer than I provided but imagine that answer would simply go into greater physiological detail, not contradict.
