GHK-Cu Copper Peptide: What It Is and Its U.S. Regulatory Status

What is GHK-Cu?

GHK-Cu is a small peptide made of three amino acids, glycine, histidine and lysine, bound to a copper ion. The GHK peptide occurs naturally in the human body and was first described in human blood plasma in the 1970s.

Today, GHK-Cu is best known as an ingredient in topical skin care and hair care products, where it is often listed as copper tripeptide-1.

U.S. regulatory status

Current status: Cosmetic ingredient (topical); injectable not FDA-approved.

Cosmetics applied to the skin are regulated differently from drugs. They do not need FDA approval before they are sold, but they cannot be marketed as medicines. GHK-Cu has not been approved by the FDA as a drug in any form, and no product meant to be taken into the body has been approved.
