This is what I argued with my friend last night when I told him I wanted to place another order with QSC. The QSC kits are 70 dollar each domestic, which is super cheap to the point I question their quality. But I've been taking them for seven months now, 5iu ED. He's been taking the Goodlyfe kits I gave him, and said generics just don't work, and that he was going to get his doctor to prescribe him GH. I told him he is going to be raped 500+ dollars to get prescribed a mere 2ius. He believes 2iu of pharm is much more potent than generics at the same doses or higher. I told him that is just a myth, and doesn't even make sense logically.
My bloodwork on Quigdao kits came back 315 at 5iu, whereas with Goodlyfe, it came back a 374 at 5ius. This variance can be several factors, but it shows the GH is real, since my levels are normally 111 or something. So unless Pharm grade 5iu will give me 500 levels, then it would be true that each pharm iu is double that of generics.
The only thing you get from prescribed pharm grade is a guarantee that it is properly dosed, and is the actual product claims. But if you have a generic source that is selling what it says it is, then you have real GH. The person on this forum who linked me to the QSC kits, is currently taking pharm grade, and he said he noticed a difference but NOT worth the money for that difference. I say it is probably placebo on his end, because he paid 5x more the price, so he is probably "noticing" things because of his investment.
I've heard some claim that pharm grade has certain secret formulas that help with the anti-bodies, duiretics in it as well, and that generics maybe real gh, but aren't 191, but 192 aa sequence. I've heard the arguments, but if you have real 191 GH, the only difference can be the purity.
