It's the best fucking gh around. It causes a lot of water retention in some people, but i swear that shit is stronger than any other gh I've used.
real talk: their advertised hgh per vial is the very highest of any hgh on the market. that is, of course if their stated hgh dosages are correct and also if their net peptide content is at least 80%, which is a metric that mean how much of that hgh is actually usable, e.g. say if they claim .4mg per iu of hgh, if their net peptide content is only 50% then there's only .2mg of actual active hgh per iu.
no one does tests on it or states it, all of them just say that the hgh is 98%+ hgh purity even though not all of it would be active hgh. best way to guestimate, unless someone wanted to drop coin for a lab analysis, would be to just go by feel, seeing how different products compare to each other at the same dosage with all other things being equal.
