Disgusted raises a good point: There is no such thing as good, bad or mediocre GH. There is real GH, fake GH and inaccurately dosed GH.
Lately a lot of competitors are talking about serum tests being performed on various steroid forums as an indicator of hgh quality. I spoke to somebody about this at length and this person (who knows his shit about hgh and bodybuilding drugs in general) firmly believes that chinese gh is often filled with other GH releasing peptides as well as other random fillers. The GH releasing peptides would account for the high serum tests coming from various chinese brands. The fillers, he said, are the reason so many people get so bloated on chinese GH.
