are u talking about the unlabelled blue top ones? If so, my sourse has them and I enquired about them. They seem to be alot cheaper, he says he has been selling them for 3 years now with no complaints. I have also done abit of research myself and they seem fine. However for Hgh I prefer to save money and invest in pharmaceutical stuff. I don't trust chinese products. Not being racist, but they just don't have good reputation.
