About GHK-Cu
GHK-Cu (Copper Peptide) is a naturally occurring tripeptide — Gly-His-Lys — complexed with a copper(II) ion. Originally isolated from human plasma, GHK-Cu is one of the most extensively studied peptides in regenerative biology, with decades of published research spanning wound healing, anti-inflammatory signalling, skin remodelling, and neuroprotection. Its primary mechanism involves upregulation of collagen, elastin, and glycosaminoglycan synthesis, alongside metalloproteinase activity that facilitates tissue remodelling. Research has demonstrated GHK-Cu's ability to influence thousands of genes associated with tissue repair and anti-aging biology, including those governing antioxidant defence, DNA repair, and cellular differentiation. In wound healing models, topical and systemic GHK-Cu has consistently accelerated re-epithelialisation, improved tensile strength of repaired tissue, and reduced scar formation. Dermatological research has demonstrated improvements in skin elasticity and promotion of hair follicle cycling. Emerging neurological research has identified neuroprotective applications in models of cognitive decline. Its outstanding safety profile and decades of literature make GHK-Cu one of the most accessible entry points in regenerative peptide research. Supplied at ≥99% HPLC purity.
Usage Guidelines
✓ Suitable For
- Excellent entry compound for wound healing and skin regeneration research
- Suitable for dermatological hair follicle and collagen synthesis studies
- Well tolerated — broad safety profile across decades of published literature
- Compatible with topical and systemic administration models
✗ Not Recommended For
- Avoid excessive doses in research — copper homeostasis should be monitored in long-term studies
