Research Background
AHK-Cu is a copper(II) tripeptide complex of alanine, histidine and lysine. Copper-peptide complexes are standard in vitro research tools for studying extracellular-matrix synthesis, collagen-related signalling and dermal fibroblast biology, where the peptide sequence acts as a delivery vehicle for copper ions. It is supplied as a research reagent only — cosmetic and clinical applications are outside its intended use.

FAQ
What is AHK-Cu?
AHK-Cu is a copper tripeptide complex formed from alanine, histidine and lysine with Cu(II) (CAS 682809-81-0). It is a research reagent for laboratory use, not a cosmetic ingredient for human application in this catalogue.
How does AHK-Cu differ from GHK-Cu?
Both are copper tripeptides, but the sequences differ: GHK-Cu is glycyl-L-histidyl-L-lysine : Cu, while AHK-Cu is alanyl-L-histidyl-L-lysine : Cu. Sequence-specific differences make them different tools in in vitro matrix-biology research.
What purity is supplied?
≥99% by HPLC; identity is confirmed by mass spectrometry and the copper content is reported per batch on the COA.
What documentation is included?
Batch-specific COA, commercial invoice and packing list. Elemental copper analysis can be requested for research documentation.
All products are manufactured for laboratory research purposes only. AHK-Cu is labeled FOR LABORATORY RESEARCH USE ONLY. Not for human or veterinary use, diagnosis, treatment, prophylaxis or any clinical, cosmetic, dietary or household application. Not a dietary supplement, pharmaceutical ingredient, cosmetic ingredient or approved drug substance.
