AHK-Cu: Copper Tripeptide Research Overview

AHK-Cu is the copper(II) complex of the tripeptide alanine-histidine-lysine. Like GHK-Cu (glycine-histidine-lysine), it binds copper through its histidine and amino-terminal groups.

Because the two complexes differ by a single residue, AHK-Cu is often examined alongside GHK-Cu in comparative copper-peptide work.

The best-known study examined AHK-Cu on cultured human dermal papilla cells and isolated hair follicles in vitro. Evidence beyond cell and organ-culture models is limited, and AHK-Cu is not an approved medicine.

Copper-peptide complexes are typically blue. Keep vials sealed and cold, avoid strong chelators or reducing agents in buffers unless intended, aliquot, and log the lot number.
