50mg vials The most common size for individual use, 50mg vials work well with 2.5-5ml bacteriostatic water

The binding constant of GHK for copper (log10 = 16.44) slightly exceeds that of albumin (log10 = 16.2), enabling the peptide to acquire Cu2+ from plasma proteins and deliver it to cells while silencing coppers potentially damaging redox activity (Pickart, 1977)
