hcg doesn't do anything to restart natural test production. post up the studies you are talking about because I believe you're missing the point somewhere(Im saying that's not the case though)
The bare minimum for clomid would be 50mg. and you need an ai for pct as well. if you dont want aromasin, check out formerone by black lion research. that's what I'll be using for pct after being on gear for 6-7months. pm if you want more info on that.
There are countless threads advicating HCG on cycle as it helps with reducing shut down, you can find them right here. I'm not saying you are wrong, I've just read too many other respected opinions and i'm not worried for a second that I'll perminately shut down, It's not like I'm doing tribulis for PCT.
I'll read more and maybe bump up the Clomid, you have raised my curiosity.
