Nothing beats good ole USA pharm grade products, period. Personally, I think most of the unlabeled shit is all the same stuff, just with different colored tops. Some people like blues, some yelllow, some red. Nothing beat Jintropins for potency. I would get sever side effects if I went to 4ius/ed. I had my bloodwork done while taking the novotropins, and it was pretty good for the the price.. To each his own.
