GHK-Cu (Copper Peptide) is a naturally occurring tripeptide-copper complex first identified in human plasma by Loren Pickart in 1973. Studied extensively in laboratory models for collagen synthesis, wound healing, antioxidant gene expression, skin biology and hair follicle research. One of the most studied cosmetic and regenerative research peptides with over 50 years of research history. Third-party verified at ≥99% purity by Janoshik Analytical.
GHK-Cu (Glycyl-L-Histidyl-L-Lysine:copper(II)) is a naturally occurring tripeptide-copper complex found in human plasma, saliva and urine. It was first identified by Loren Pickart in 1973 while researching why old liver tissue performed poorly when exposed to young plasma — leading to the discovery of this regenerative signalling molecule.
GHK-Cu acts as a potent biological modulator with effects on a remarkably broad range of genes and biological processes. Studies have identified over 4,000 human genes regulated by GHK, including genes involved in collagen and glycosaminoglycan synthesis, antioxidant and anti-inflammatory pathways, DNA repair mechanisms and tissue remodelling. Its copper chelation forms a key part of its biological activity — copper being essential for numerous enzymatic processes including lysyl oxidase-mediated collagen cross-linking.
All Pureline Biolabs GHK-Cu is supplied as a lyophilised powder in sealed vials, third-party tested by Janoshik Analytical with certificates available on our Lab Reports page.

GHK-Cu has been studied for over 50 years across wound healing, skin biology, hair follicle, antioxidant and gene regulation research. This product is supplied for laboratory research purposes only.
Studies have demonstrated GHK-Cu's ability to stimulate collagen synthesis in fibroblast models, examining type I, III and IV collagen production, as well as elastin and glycosaminoglycan synthesis — key structural components of skin and connective tissue.
Laboratory and animal studies have examined GHK-Cu's acceleration of wound closure rates, measuring re-epithelialisation speed, angiogenesis promotion and inflammatory resolution compared to untreated wound models.
Genomic studies have identified over 4,000 human genes regulated by GHK-Cu, with research examining its effects on antioxidant gene expression, DNA repair genes and tissue remodelling pathways including MMP regulation.
Studies have investigated GHK-Cu's antioxidant properties, examining its ability to upregulate endogenous antioxidant enzyme expression, scavenge reactive oxygen species and protect against oxidative damage in cell culture models.
Laboratory studies have examined GHK-Cu's effects on hair follicle biology, measuring follicle size, hair shaft diameter and follicle cycling in animal models, with research suggesting stimulatory effects on follicle growth phase duration.
Some studies have investigated GHK-Cu's neuroprotective properties, examining its effects on neuronal survival under oxidative stress conditions and its regulation of genes involved in nerve growth factor signalling.
Store in refrigerator. GHK-Cu is relatively stable but keep away from direct light and heat.
Use within 28 days. Solution will appear blue — this is normal for the copper complex.
Stable for up to 24 months when frozen as lyophilised powder.
GHK-Cu powder and solution are characteristically blue/blue-green due to the copper complex. This is normal and expected.
GHK-Cu is supplied as a lyophilised powder and must be reconstituted with bacteriostatic water before use in research applications. The resulting solution will be blue — this is normal and expected for the copper peptide complex.
Allow vial to reach room temperature. Clean the rubber stopper with an alcohol swab and allow to dry completely.
Draw required volume of BAC water into a sterile syringe. Inject slowly down the inside of the vial wall — not directly onto the powder.
Gently swirl until powder fully dissolves. Solution will be clear blue to blue-green in colour. This is the copper complex and is completely normal.
