AHK-Cu: a copper-peptide overview

AHK-Cu is a copper peptide studied in skin and hair-follicle research. This overview covers what it is and how it is handled, with no therapeutic or dosing claims.

What it is

AHK-Cu pairs a tripeptide — alanine, histidine and lysine — with a copper(II) ion, much as GHK-Cu does with its own tripeptide. The copper ion is integral to the molecule's identity.

Why it is studied

AHK-Cu appears in cosmetic and hair-follicle research literature, frequently alongside GHK-Cu. The findings belong to those studies; this page makes no claim about human effects.

Handling notes

• Supplied lyophilised, often with a blue tint from the copper complex.
• Reconstitute gently; protect from prolonged light.
• Refrigerate after reconstitution and aliquot for repeated use.

For in-vitro research use only. Not for human or veterinary use.
