Rules & Safety

Legal Status and Safety

Important: A cream containing copper tripeptide-1 and a vial of research-grade GHK-Cu fall under completely different rules. Neither is an approved medicine for treating any condition.

GHK-Cu occupies an unusual position. It is a familiar cosmetic ingredient, yet the same molecule is also sold as a research chemical. How it is regulated depends on how it is made, sold and described.

As a Cosmetic Ingredient

In the EU and UK, cosmetics must be safe, have a responsible person and carry an ingredient list, but they need no pre-market approval. GHK-Cu appears on labels as copper tripeptide-1. Cosmetics may claim to care for or improve the appearance of skin, but not to treat disease.

As a Medicine

EU and UK: no medicinal product containing GHK-Cu has been authorised. Promoting it to treat wounds, hair loss or any illness would make it a medicine in law.
US: the FDA has not approved GHK-Cu as a drug for any use.
Other countries: rules on importing and holding research peptides differ, so check the local law.

In Sport

GHK-Cu is not named on the World Anti-Doping Agency list. The list does, however, include a general category for substances not approved for human therapeutic use, so athletes should ask their anti-doping organisation before using any peptide product.

What Is Known About Safety

Topical use in cosmetics has a long track record, but published safety data in peer-reviewed journals are limited.
Injected use has not been tested in published controlled trials.
Copper load: copper is essential, but too much is harmful. People with disorders of copper metabolism, such as Wilson disease, face particular risks.
Cell growth: GHK stimulates blood vessel growth and, in the first study, tumour cell growth. Its effect in people with cancer is unknown.
Product quality: research-grade products are not made to cosmetic or pharmaceutical standards and may vary in purity and copper content.

Research Material Is Not Skincare

Material labelled "for research use only" is supplied for laboratory experiments. It comes with no safety assessment for skin or injection, no directions and no regulatory oversight.

Bottom Line

GHK-Cu is legal as a cosmetic ingredient within cosmetics law, but it is not a medicine. Anyone considering it for a health reason should speak to a doctor or dermatologist first.

The above is a general summary, not legal advice.
