See this is what I was thinking is the way it lowers it. So realistically...if one was using GH or GH releasing peptides, the nolvadex shouldn't have much if any impact on IGF-1!
This explains a lot to me. Most of the biggest guys rarely, if ever, use any AIs while on. They mostly use nolva just to control gyno. Pretty much all of them are on GH, using IGF-1, peptides, etc. This, other than better genetics, explains why they grow better when using gear compared to most guys these days. For the most part, everyone that comes on these forums runs an AI alongside their blast.
Recently, I've stopped using any AIs at all to let my e2 rebound and help with the healing process. I've also started growing a lot while still in a caloric deficit. Much more than I did while running AIs. Obviously I'm no genetic gift when it comes to putting on muscle, but I've gained a lot more since I stopped all AI use. I retain water easier (especially when cheating), but that's easily remedied with increased water intake and clean diet. Rarely I'll throw in a little bit of HCTZ if it makes my blood pressure high. The only other issue is that the 'ol D doesn't like to work as well, but that's also easily remedied with my 5mg cialis daily that I take anyways to be able to piss. Sure there's less sensitivity, but whatever.
Next blast I think I'm going to run no AI and see how much I grow compared to the past. I have the feeling it'll be a pretty significant difference. Especially considering I've been gaining muscle while in a pretty decent caloric deficit.
