That's the question of the ages right there bro. Pharm grade obviously, but we're not all millionaires. The generics are tough, they're often hit or miss. Soon as Someone's putting out amazing black-tops, yellow tops, or riptropins, hygetropins, any-tropins, there's another untold number of assholes labeling hcg or ghrp or some other cheap sht with that same label, same packaging. Happens all the time, shame, but where the $$ is at, that's where the fakes flow. Find a source, get bloods done, and if its good, you kidnap that man quick and chain him to the radiator in the basement before anyone finds out. Then, very important: then you call me haha
Good luck!
