GHK-Cu and AHK-Cu are structurally related copper-binding peptides studied for their roles in Wnt/beta-catenin signaling in hair follicle stem cells, dermal papilla cell proliferation, and anagen phase initiation
That substitution is thought to shift the peptide's affinity more specifically toward hair follicle cells, rather than toward the broader tissue-repair profile of GHK-Cu
The compound has substantial cosmetic-ingredient regulated use in topical preparations under the relevant cosmetic regulatory frameworks, distinct from any pharmaceutical approval
