Description
All presented information is based on scientific publications which can be found at the end of product description below.
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide first discovered in human plasma in 1973. Its biological effects are mediated through copper(II) ion binding and broad-spectrum gene expression modulation. Research Highlights 1. Skin Rejuvenation — Tightens skin, repairs barrier proteins, improves firmness and elasticity. Reduces fine lines, wrinkles, and photodamage.
2. Gene Expression — Up/down-regulates numerous genes via Connectivity Map analysis. Activates collagen synthesis, angiogenesis, fibroblast activity.
3. Tissue Regeneration — Promotes regeneration in lungs, bones, liver, and stomach lining. Stimulates collagen, elastin, and glycosaminoglycan synthesis.
4. Neuroprotection — Alleviates neuronal apoptosis via miR-339-5p/VEGFA pathway.
5. Pulmonary Protection — Inhibits pulmonary fibrosis and acute lung injury.
6. Antimicrobial — GHK-Cu conjugates show antimicrobial activity in vitro. References available upon request. The product is intended for scientific research and development purposes only.

Frequently asked questions
- GHK is a tripeptide (Gly-His-Lys) endogenously found in human plasma. GHK-Cu is its copper(II) complex (C₁₄H₂₄N₆O₄Cu, MW ≈ 403.9 g/mol). Many of the biological activities reported in literature are attributed to the copper complex specifically, not the bare peptide.
- Batch-level CoA information is available where applicable and focuses on purity testing and lot details.
- Store lyophilised GHK-Cu at -20 °C in a sealed vial protected from light - the copper complex is sensitive to light and oxidation. Reconstituted solutions should be used promptly or stored short-term at 2-8 °C in the dark.
- GHK-Cu is studied in dermal fibroblast culture, full-thickness skin-repair models, hair follicle biology, and gene-expression-modulation research (transcriptomic studies suggest GHK-Cu influences thousands of human genes related to ECM, antioxidant defense, and inflammation).
- GHK-Cu appears in topical cosmetic literature and product categories in some jurisdictions. Research-grade GHK-Cu supplied by Peptra Labs is for laboratory research only and must not be used as a cosmetic, medicine, or veterinary product.
