I get Omnitrope, and I got some chinese due to price to try it out..Hygetropin I think which is supposed to be a good Chinese version...hell in two weeks my joints sore as heck....could be that I upped the dose a little, but im more thinking its the chinese stuff...it was pretty noticable and only thing i changed in my daily routine...once i run out of chinese im sticking to high quality pharm stuff...
