PuraCore summary of this report (PDF)
Overview

GHK-Cu.

GHK-Cu is a complex, not a bare peptide. The tripeptide glycyl-L-histidyl-L-lysine holds a single copper(II) ion, coordinated through the histidine and the peptide backbone. Because the metal belongs to the molecule, copper is written into the formula, and the cake in the vial is blue where most peptides are white.

Loren Pickart first isolated the tripeptide from human plasma in 1973 and noted how tightly it holds copper. With only three residues it sits among the smallest entries here, and among the best characterized. It comes in sealed vials of 50 mg or 100 mg, freeze-dried.

PuraCore offers no advice on how any material is used, prepared or applied. Deciding whether it fits your research rests with you or your institution.
