Is AHK-Cu with GHK-Cu legal in Canada?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
AHK-Cu with GHK-Cu can be sold in Canada as a supplement or cosmetic ingredient. Its legal category is "Permitted in cosmetics". That is not approval as a drug. Health Canada has not checked any health claim made for it. Versions you inject, and "research use only" versions, fall outside supplement rules, so that label does not make them legal to use in people. On the evidence, 1 completed human trial is cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
AHK-Cu with GHK-Cu can be sold in Canada as a supplement, food or cosmetic ingredient, under the legal category above. It has no approval as a drug.
- 02
Being sold as a supplement means Health Canada has not checked any health claim. The makers are responsible for safety and labels, and quality varies from product to product.
- 03
Versions you inject, and "research use only" versions, are not supplements. That label does not make them legal to use in people, and anything you inject falls under the rules for medicines.
What AHK-Cu with GHK-Cu is
Two copper peptides in one serum, sold for hair and skin. There is not one published paper on AHK-Cu under that name. So half the product has no research at all. The other half's evidence in people is a cream that failed when checkers scored it, in 13 patients. Brands do not agree on strengths, so there is no way to work out how much goes on per use.
AHK-Cu is a small three-building-block peptide bound to copper. It is a close cousin of the better known GHK-Cu.
How it works: Both are small copper-bound peptides that carry copper into tissue. Both are claimed to signal skin cells and hair root cells.
Approval history: Cosmetic ingredients. Not approved drugs. A claim that it regrows hair or changes the skin itself would make the product a drug.
How Health Canada treats this kind of product
Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.
The legal category above is how The Longevity Archive reads Health Canada, Health Products and Food Branch listings for AHK-Cu with GHK-Cu on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
AHK-Cu with GHK-Cu in sport and the military
Whether AHK-Cu with GHK-Cu is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Canada. Before you compete or get tested, look up AHK-Cu with GHK-Cu by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
