Healing, recovery & inflammation research
GHK-Cu is a copper-binding tripeptide studied extensively in skin, collagen, and gene-expression research. For research purposes only.
Also known as: Copper Tripeptide-1 · GHK-Cu copper complex · Copper peptide GHK-Cu · Glycyl-L-histidyl-L-lysine copper
GHK (glycyl-L-histidyl-L-lysine) forms a complex with copper(II). The complex has been researched for wound-healing models, extracellular matrix remodeling, and broad gene-expression effects in laboratory systems. Cosmetic science literature is substantial; injectable research vials are a different use-case and regulatory context.
Confirm whether a listing is a cosmetic ingredient, topical research material, or lyophilized vial. COAs should match the claimed form.
GHK-Cu research materials are not FDA-approved drugs. Cosmetic uses, where regulated, follow separate rules.
Companies on PurityWatch may list GHK-Cu as a compound they offer for research. Listing a compound does not mean it is approved for human use.
Much literature focuses on skin and tissue-remodeling models, but catalogs may list multiple formats. Always read the exact product specification.
