Tons of stuff on this forum about HGH, there was a big thread recently which concluded by some pretty senior guy's that much of the HGH is counterfeit.
I use HGH that I buy direct from the manufacturer that is reputed by many to be 192 amino acids and by others to leave you with red welts.
I am trying to get a mass spectrometer analysis sorted out to prove the 191 or 192 amino acids myth, but can report that it never leaves red welts.
Suggest you take 4iu per day 5 days on 2 days off or 4 on 3 off
