Overview
GHK-Cu is a naturally occurring tripeptide complexed with copper, widely studied in research on skin, the extracellular matrix, and regenerative response. It is one of the best-known peptides in the cosmetic-science space.
Technical details
Gly-His-Lys tripeptide bound to a copper ion (Cu²⁺). Studied in collagen remodeling and tissue signaling.
What sets it apart
A peptide-plus-copper complex, a unique profile across the catalog.
A long track record in dermatological research.
Purity ≥ 99% with a COA per batch.
Handling & warnings
For research and laboratory use only.
Blue-tinted lyophilized powder (the copper color is normal, not a defect): reconstitute with bacteriostatic water.
Keep refrigerated (2 to 8 °C) after reconstitution and protect from light.
FAQ
Is GHK-Cu lyophilized? Yes. It is a lyophilized powder, but blue-tinted because it contains copper, not white.
Is the blue color normal? Yes, that is the characteristic color of the copper complex. It indicates the correct product.
How do I reconstitute and store it? Bacteriostatic water down the vial wall; once reconstituted, refrigerate (2 to 8 °C) and protect from light.
What is the purity? Is there a COA? ≥ 99%, with a COA per batch.
Why is it so studied for skin? Because of the tripeptide's role in extracellular-matrix signaling observed in studies.
