GHK-Cu (Copper Tripeptide-1) is a high-purity copper-peptide complex comprising the sequence Gly-His-Lys chelated with copper(II). This potent complex has been extensively studied for its ability to stimulate skin repair and collagen synthesis.
Mechanism of Action
GHK-Cu modulates multiple cellular pathways in skin regeneration, stimulating collagen production and enhancing tissue strength (Pickart et al., 2015). The complex activates fibroblasts and promotes angiogenesis with documented anti-aging properties (Dou et al., 2020).

GHK-Cu is supplied as a lyophilized powder. Keep it sealed, dry, and away from light until reconstitution.
Lyophilized material is stable when frozen. Once reconstituted, keep it cold and minimise handling to preserve integrity.
GHK-Cu is a synthetic peptide compound used in laboratory research settings. Researchers studying tissue repair and regeneration mechanisms use this compound to investigate cellular signaling pathways, receptor binding affinities, and structure-activity relationships. Its available Certificate of Analysis documents the reported laboratory results.
GHK-Cu is a research compound supplied for in-vitro laboratory use. Also known as GHK Cu, Copper Peptide, Copper Tripeptide, Copper Tripeptide-1. Mechanism class: Gly-His-Lys:Cu. Supplied for tissue repair laboratory research. A third-party Certificate of Analysis is published for the current lot. Research Use Only — not for human or veterinary use.
The current Certificate of Analysis for GHK-Cu reports 99.937% purity by HPLC (Accumark Labs report JWJT-9WMJ).
