GHK-Cu — the copper-binding tripeptide glycyl-L-histidyl-L-lysine bound to copper — is one of the most-studied peptides in skin, wound, and tissue-regeneration research. It occurs naturally in human plasma and declines with age, which is part of why it has drawn sustained research interest. This overview is for educational reference only.
What is GHK-Cu?
GHK-Cu is a small copper-carrier peptide. In the research literature it is examined for its role in extracellular-matrix remodeling, copper transport, and signaling related to skin and connective tissue. It is supplied as a lyophilized powder (often pale blue due to its copper content).
Research focus areas
- Skin remodeling: studied in collagen and extracellular-matrix research models.
- Wound research: examined in tissue-repair and regeneration pathways.
- Antioxidant and copper-transport signaling: investigated for its role in delivering copper to cells.
Handling and quality
Reconstitute lyophilized GHK-Cu with bacteriostatic water for research handling. Because GHK-Cu is frequently studied alongside other recovery peptides, researchers also use the combined BPC-157 + GHK-Cu + TB-500 blend. Always confirm identity and purity via a batch-specific Certificate of Analysis.
