What Is the Difference Between GHK and GHK-Cu?
Short answer: GHK is the tripeptide glycyl-L-histidyl-L-lysine on its own — a white powder of about 340 Da. GHK-Cu is that peptide with one copper(II) ion bound to it, a blue complex about 63 Da heavier. In plasma the peptide picks up copper readily, so the two are not always distinguished in the literature, but most experiments and all cosmetic use involve the copper form. The pack listed by REVIVE LAB UAE is GHK-Cu.
Some papers argue that the biological activity requires the copper, others that the peptide carries copper to where it is needed; the distinction between those two readings is the subject of a knowledge page.
Analytically the two are told apart by mass and by colour, both of which appear on the certificate.
