Research profile
AHK-Cu research profile
AHK-Cu is the copper(II) complex of the tripeptide L-alanyl-L-histidyl-L-lysine (AHK). It is a close structural analog of GHK-Cu: the N-terminal glycine is replaced by alanine, while the His-Lys copper-binding motif is kept.

Published research
- Hair follicle cell culture: a tripeptide-copper complex was studied for its effect on cultured human hair follicles in vitro (Pyo et al., Arch. Pharm. Res., 2007).
- Dermal papilla cells: AHK and dimeric AHK derivatives were evaluated for proliferation of primary human dermal papilla cells in culture (Jeong, Park & Kim, Bull. Korean Chem. Soc., 2021).
- Structure–activity: AHK-Cu is often studied alongside GHK-Cu to compare how the N-terminal residue affects copper binding and activity in cell models.
Frequently asked questions
What is the difference between AHK-Cu and GHK-Cu?
Only the first amino acid differs: AHK-Cu has alanine where GHK-Cu has glycine. Both keep the His-Lys copper-binding motif. Our guide compares the two in more detail.
How much AHK-Cu is in each vial?
Each vial contains 100 mg of lyophilized AHK-Cu.
How do I verify my lot?
Scan the QR code on the vial to open the certificate of analysis for that lot, including HPLC purity and mass spectrometry identity.
