doesn't indicate purity, also other things raise IGF... still no 97+% purity on jano testing from TP or customers, rather the opposite tests pretty low... which is fine, just misleading when says they are 98% pure when more likely 92.5% (for mauves) or 93.5% (gold).. tops being more or less meaningless one should assume all TP HGH is in that lower range for generics until a body of evidence to the contrary. again, which is fine and great no dimmer, its just not "premium" level generic is all (97+% no dimmer being premium)..
also very possible purity has slipped as TP stopped jano testing, as perhaps started getting lower %.. as would assume in best interest to silence nay sayers..
