Every lot of AHK-Cu is tested by an independent ISO/IEC 17025-accredited lab in the USA. 99%+ purity isn't a target here. It's the requirement.
Don't take our word for it: test any vial at an accredited lab of your choice. If HPLC purity comes back under 99%, we refund your order and pay for the test.
AHK-Cu is a copper-binding tripeptide (Ala-His-Lys) studied alongside GHK-Cu in copper-peptide research. Published work focuses on dermal papilla and follicle models and on vascular endothelial growth factor expression in culture. For laboratory research use only.

Copper-Binding Tripeptide
Structure
AHK forms a complex with copper(II) in the same family as GHK-Cu. Copper-transport behaviour is the shared characterised property across the copper-peptide class.

FAQ
Common questions about AHK-Cu
Both are copper-binding tripeptides, but the sequences differ: AHK is Ala-His-Lys and GHK is Gly-His-Lys. AHK-Cu's published literature focuses on follicle and dermal papilla models.
The molecular weight will be published here from the lot's Certificate of Analysis rather than quoted from a secondary source.
Copper-peptide complexes are characteristically blue to blue-violet. The colour comes from the copper(II) coordination.
Each lot is analysed by reverse-phase HPLC and released at ≥99%, with a Certificate of Analysis.
Store lyophilized at -20°C for long-term stability, protected from light and moisture, and avoid repeated freeze-thaw cycles.
