AHK-Cu
Skin & HairPreclinicalAlso known as: Copper Tripeptide-2, Ala-His-Lys-Cu, AHK Copper Peptide, Copper Tripeptide AHK
AHK-Cu (Ala-His-Lys-Copper) is a copper chelating tripeptide related to but distinct from GHK-Cu (Gly-His-Lys-Copper). Where GHK-Cu is the most-studied copper peptide and naturally occurs in human plasma, AHK-Cu is a synthetic structural analog with enhanced copper-chelating affinity.
Overview
At A Glance
AHK-Cu delivers bioavailable copper ions to follicular and dermal tissues. Copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase (antioxidant), and vascular endothelial growth factor (VEGF) signaling. The tripeptide backbone penetrates …
Overview
AHK-Cu (Ala-His-Lys-Copper) is a copper chelating tripeptide related to but distinct from GHK-Cu (Gly-His-Lys-Copper). Where GHK-Cu is the most-studied copper peptide and naturally occurs in human plasma, AHK-Cu is a synthetic structural analog with enhanced copper-chelating affinity. Both peptides activate hair follicle stem cells and promote keratinocyte proliferation, but AHK-Cu appears to have stronger follicle-stimulating activity in some preclinical comparisons. Research applications center on androgenetic alopecia, scalp vascularity, and wound healing, typically in topical formulations or via mesotherapy injection. AHK-Cu is used in cosmetic compounding for scalp treatments targeting hair miniaturization.
