What Is AHK-Cu?
AHK-Cu is a copper tripeptide closely related to GHK-Cu: the N-terminal glycine of GHK is replaced by alanine, giving Ala-His-Lys. Like GHK, the histidine and lysine residues chelate a copper(II) ion, and the complex carries the same characteristic blue colour. Our AHK-Cu 100mg vial contains the copper complex with a molecular weight of approximately 418 Da.
AHK-Cu has been studied mainly in dermal papilla and follicle cell models, where it is compared with GHK-Cu and other copper peptides. The 100mg fill suits laboratories running larger cell-culture studies, and the lyophilised format keeps the complex stable in storage.
AHK-Cu Research Areas
Laboratory studies of AHK-Cu cover the following areas:
Dermal Papilla Cell Models
AHK-Cu is studied for its effect on dermal papilla cell proliferation and on growth-factor expression in follicle-derived cultures. Published work can be explored on PubMed.
Copper Peptide Comparison Studies
Because it differs from GHK-Cu by a single methyl group, AHK-Cu is used in structure–activity studies of copper-peptide binding and cellular uptake.
Extracellular Matrix Signalling
Fibroblast models examine AHK-Cu alongside GHK-Cu for effects on collagen and elastin synthesis.
Vascular Endothelial Models
Endothelial cell assays have examined AHK-Cu for effects on VEGF expression and tube formation.
AHK-Cu vs GHK-Cu
GHK-Cu is the more extensively characterised of the two copper peptides, with a large literature on extracellular matrix remodelling and gene expression. AHK-Cu is studied more narrowly, chiefly in follicle and dermal papilla models. Researchers comparing copper peptides frequently run both under the same conditions; see our guide What is GHK-Cu? for background on the parent structure.

Quality Control and Batch Testing
Every batch of AHK-Cu 100mg is analysed before release. HPLC confirms purity, and mass spectrometry confirms that the peptide mass matches the expected structure. You can view current certificates on our verification and testing page.
Storage and Handling
Store lyophilised AHK-Cu at −20°C for long-term stability, protected from light and moisture. Reconstitute with bacteriostatic water using aseptic technique, then keep the solution refrigerated at 2–8°C and use promptly. See our guides on how to reconstitute peptides and how to store research peptides.

AHK-Cu 100mg FAQs
What is AHK-Cu?
AHK-Cu is the copper(II) complex of the tripeptide Ala-His-Lys, a close analogue of GHK-Cu used in follicle, dermal papilla and copper-peptide comparison research.
How does AHK-Cu differ from GHK-Cu?
The N-terminal residue is alanine instead of glycine. Both peptides bind copper(II) through the histidine and lysine side chains.
Does AHK-Cu 100mg need reconstituting?
Yes. It is supplied as lyophilised powder and should be reconstituted with bacteriostatic water before use in research protocols.
How is AHK-Cu 100mg tested?
Every batch is tested to ≥99% purity by HPLC, with identity confirmed by mass spectrometry, at an ISO 17025 accredited third-party laboratory.
How should AHK-Cu be stored?
Keep the lyophilised vial at −20°C for long-term storage, protected from light. Once reconstituted, refrigerate at 2–8°C and use promptly.
Is AHK-Cu 100mg for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or veterinary use.
