Copper peptide research materials
For research use only. Not for human or animal use.
This page lists copper(II) tripeptide complexes in the research catalog. GHK-Cu is the complex of glycyl-L-histidyl-L-lysine. AHK-Cu is the complex of alanyl-histidyl-lysine, the same His-Lys motif with alanine in place of glycine.
Pickart isolated GHK in hepatocyte culture. Public papers on AHK-Cu are fewer. Copper stoichiometry, counter-ion, and whether a lot is the free peptide or the complex are certificate-of-analysis facts.
These rows are laboratory materials. They are not a finished preparation, and this page does not describe a personal-care use.
