It is very hard to generalize about blue tops unless you are getting them from the same source. I saw at least a dozen Chinese vendors on an Asian web page trying to hawk HGH. A lot of those had blue tops and were most likely from different factories. Blue is just a color after all. It won't be long before some scammer puts blue tops on some HCG and sells it as HGH. But for now at least the general consensus is that the blue generics give good clean results. Some say outstanding. As long as it is not 192aa which is the body inclusion technology that humans build antibodies to, then it's all good. Especially the hit to the wallet.
Personally, I am going to try some of the new peptides too. If they can substitute (doubtful) or even augment (maybe) Synthetic HGH, then that way is worth a shot. A month's worth of HGH, even blues, is still half a car payment.
