AHK-Cu with GHK-Cu can be sold in Australia as a supplement or cosmetic ingredient, classified as "Permitted in cosmetics". That is not drug approval: TGA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What AHK-Cu with GHK-Cu is
Two copper tripeptides in one serum, sold for hair and skin. PubMed returns no publication for AHK-Cu under that name, so half the product has no literature at all, and the other half's human evidence is a cream that failed its blinded endpoints in 13 patients. Serum concentrations are not consistent between brands, so no per-application arithmetic is possible.
AHK-Cu is alanyl-histidyl-lysine bound to copper, a sibling of the better known glycyl-histidyl-lysine complex. It appears in hair serums alongside GHK-Cu on the strength of a claim that it targets follicles while the other targets skin.
Mechanism: Both are copper-bound tripeptides that deliver copper to tissue and are claimed to signal fibroblasts and follicular cells. GHK-Cu has published gene expression and cell culture work behind those claims.
Regulatory history: Cosmetic ingredients. Not approved drugs, and a hair regrowth or structural skin claim would make the product a drug.
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 AHK-Cu with 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.
