About GHK-Cu
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring tripeptide-copper complex first isolated from human plasma in 1973 by Loren Pickart at the University of California San Francisco. It is one of the most extensively studied peptide compounds in existence, with over five decades of published research across wound healing, skin biology, collagen synthesis and longevity science.
GHK-Cu acts as a copper chaperone, facilitating copper delivery to copper-dependent enzymes including lysyl oxidase (critical for collagen and elastin cross-linking) and superoxide dismutase. It also activates a broad range of genes involved in tissue remodelling, antioxidant defence and anti-inflammatory signalling.
All Pureline Biolabs GHK-Cu is supplied as a lyophilised powder in sealed copper-cap vials, independently tested by Janoshik Analytical at 99.700% purity with copper content confirmed at 8.98mg per 50mg vial.

Research Background
GHK-Cu has one of the broadest published research profiles of any peptide compound, spanning wound healing, skin biology, collagen synthesis, antioxidant biology and longevity science. This product is supplied for laboratory research purposes only.
Studies have demonstrated GHK-Cu’s ability to stimulate collagen and elastin synthesis in fibroblast models, examining the mechanisms of lysyl oxidase activation, TGF-β modulation and extracellular matrix remodelling.
Extensive laboratory and clinical research has investigated GHK-Cu’s wound healing properties, examining angiogenesis promotion, keratinocyte migration, fibroblast proliferation and overall tissue regeneration rates in animal and in vitro models.
Studies have examined GHK-Cu’s activation of antioxidant gene expression including superoxide dismutase and glutathione synthesis, investigating its role in cellular protection against oxidative stress.
Microarray studies have identified GHK-Cu as a broad gene expression modulator, activating over 4,000 genes associated with tissue maintenance, inflammation regulation and cellular repair mechanisms.
Laboratory research has characterised GHK-Cu’s anti-inflammatory properties, examining its effects on TNF-α production, NF-κB signalling and inflammatory cytokine cascades in cell culture models.
Emerging research has investigated GHK-Cu’s relationship to ageing biology, examining its declining plasma levels with age, its effects on senescence markers and its potential role in longevity pathways including FOXO3 signalling.
Store in refrigerator. Keep away from direct light and heat sources.
Use within 28 days. Do not refreeze once reconstituted.
Stable for up to 24 months when frozen as lyophilised powder.
Keep away from direct light. The copper component can be light sensitive — store in original packaging.
Reconstitution Guide
GHK-Cu is supplied as a lyophilised powder and must be reconstituted with bacteriostatic water before use in research applications.
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. GHK-Cu solution will have a slight blue tint due to the copper complex — this is normal and expected.
