Members, love ZPHCD Growth Hormone. It is on the same lines of Spectrum, Saizen, Norditropin, Omnitrope, and Humatrope. the ZPHC comes in 100 and 120 iu's 10 vials per box. The spectrum 140 and 150 iu's is most popular. Please don't confuse these to with the unlabeled and possible 192. !92 amino and the real 191 is a big difference. Many online sources may pass off the cheaper 192 off as the real 191 amino HGH. Be aware of any cheap unlabeled HGH. Pirated products is at a all time high these days.
