I've been a 'tester' for probably 5-6 different pep companies, and had huge supplies of the stuff.
my experience/opinion?
I like igf1 preworkout. works fucking great. I use 100mcg per muscle trained.. sometimes up to 200mcg per muscle. keep in mind, most the studies on igf1 were using 13-20MG's! not mcg's per day. lol
I use ghrp2 primarily to make me hungry all day. a 500mcg dose in the am.. maybe 800mcg, and I'm thinking about food allllllll day. it does put some water on me and give me some fullness, even if I don't increase my food/kcal intake.
would I PAY for pep's? No. If I wasn't in the biz I'm in and actually had to budget for PED's, I'd spend my money on more AAS first, then gh second.
I'd rather keep test at 1g, and add tren up to 1500 and npp up to 1500 and methyltrienolone up to 2mg/day and dbol at 150 preworkout.. then add gh and cut the doses of everything by about 40%... gh along with lantus insulin at 15iu in the morning.
.... all that before I spent money on pep's.
