Copper Tripeptide
50 mg / Lyophilized powder
Brand vial shown. Refer to the product details for compound and quantity.
GHK-Cu is a copper-binding tripeptide complex based on glycyl-L-histidyl-L-lysine. It is one of the most recognized copper peptides in tissue remodeling research, with literature covering wound-healing models, collagen and extracellular-matrix signaling, antioxidant response, and skin-repair pathways.

Report issued July 30, 2026.
GHK-Cu is studied as a copper-binding peptide complex involved in extracellular-matrix remodeling, collagen signaling, and oxidative-stress response pathways. Copper coordination is central to its research profile, distinguishing it from hormone or receptor-agonist peptides.
Store lyophilized powder at -20°C, protected from light and moisture. Once reconstituted, store at 2-8°C and use within 30 days.
Reconstitute with bacteriostatic water. Add solvent slowly along the vial wall. Do not shake — gently swirl until fully dissolved.
From the community
Feedback on GHK-Cu.
There are no published customer reviews for GHK-Cu.
A closer reading
One selected primary paper, with its findings and limits. A starting point for reading, not a complete assessment of the evidence.
Fibroblast cultures
The researchers measured increased collagen synthesis in fibroblast cultures exposed to GHK-Cu, independent of changes in cell number.
A cell-culture endpoint does not establish visible skin changes, clinical wound healing, or the safety of an administration route.
