What GHK-Cu is
A naturally occurring copper-binding tripeptide widely used in skincare and studied for wound healing and skin remodeling.
GHK-Cu is a copper-binding peptide present in human plasma that declines with age. It is one of the better-studied cosmetic peptides, with research on skin remodeling, collagen production, and wound healing.
Mechanism: Delivers copper and modulates genes involved in tissue remodeling, stimulating collagen and glycosaminoglycan synthesis and supporting wound repair.
Regulatory history: Not an approved drug; permitted as a cosmetic ingredient
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for GHK-Cu at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
