What is AHK-Cu?

AHK-Cu is a copper complex formed from the three-amino-acid sequence alanine-histidine-lysine. It gives researchers a compact metallopeptide for studying copper coordination and cell-response pathways without confusing it with the related GHK-Cu complex.

Published laboratory work has examined AHK-Cu in cultured dermal papilla cells and ex vivo human hair-follicle models. Those findings are experimental and do not establish a medical, cosmetic, or human-use outcome.

How It Works

01

Coordinates copper through a defined tripeptide: The Ala-His-Lys scaffold forms a small copper-binding complex for controlled biochemical study.

02

Supports cell-response measurements: In vitro research has examined dermal papilla-cell proliferation and apoptosis-associated markers after AHK-Cu exposure.

03

Enables ex vivo follicle-model research: Published work reported changes in human hair-follicle elongation under laboratory conditions, not a proven clinical effect.

Why Source from 321 Peptides?

Domestic accountability.

AHK-Cu is synthesized, manufactured, formulated, finished, and packaged in Certified GMP laboratory facilities in California and Arizona—never sourced from overseas or Mexico. That creates direct domestic supply-chain accountability from production through fulfillment.

Verification you can inspect.

Independent third-party HPLC evaluates the ≥99% purity target, while mass spectrometry confirms molecular identity. The results are documented in one combined, batch-specific Certificate of Analysis report.

Protected in transit.

Freeze-drying helps preserve compound stability during storage and shipping. Rapid domestic fulfillment reduces unnecessary time and handling in the delivery network.

Frequently Asked Questions

What is AHK-Cu peptide?

AHK-Cu is the copper complex of the tripeptide alanine-histidine-lysine. It is studied as a defined metallopeptide in cellular and ex vivo research models.

What is the difference between AHK-Cu and GHK-Cu?

AHK-Cu begins with alanine, while GHK-Cu begins with glycine; both contain histidine and lysine and can coordinate copper. They are distinct compounds and should not be treated as interchangeable.

Is AHK-Cu FDA approved?

No, AHK-Cu is not an FDA-approved drug product for human use. This vial is supplied exclusively for controlled, non-clinical research.

Which COA applies to my vial?

The lot code printed on the vial. Select it above and the certificate for that batch is returned, including the chromatogram it came from.
