This is what I have been doing.
GHRP-6 or GHRP-2 along with MOD GRF-129 at 100mcg each, wait 10-15 minutes, and then pin 2iu's of GH.
Repeat every 4 hours or so.
Get your peps from the sponsers here such as Ergo, Osta, Extreme, Great White as I have had good results with various products I have ordered along with many others on here.
As far as how much peps amplify the affect...it's really hard to tell as I don't think anyone has put a definitive # on it.
All I know is that it works. At 2iu's I didn't get any sides at all from my GH. By adding the peps in, it was like it put me over the edge and I started getting all the minor symptoms such as tingling fingers...etc.
