Figures are illustrative of published preclinical research and are provided for orientation only. They are not claims about this product.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine) complexed with copper(II). It occurs naturally in human plasma and has been studied extensively in relation to extracellular matrix remodelling. Its characteristic deep blue colour comes from the copper complex.
Signalling pathways examined in preclinical models. Descriptive of published research directions, not claims of effect.
Studied in relation to collagen and glycosaminoglycan synthesis in dermal fibroblast cultures, and to the balance of matrix metalloproteinases and their inhibitors.
The tripeptide's affinity for copper(II) is the basis of much of its characterisation; both the peptide purity and the copper stoichiometry are assayed on every lot we release.
Widely used in in-vitro skin models examining matrix protein synthesis.
Applied in preclinical wound-healing preparations examining tissue remodelling markers.
Illustrative of published preclinical findings. Not a representation of this product’s performance, and not a claim of any effect in humans.

The colour comes from the copper(II) ion coordinated by the tripeptide. A pale or colourless lot would indicate incomplete complexation, which is why we assay copper stoichiometry as well as peptide purity.
Store the sealed vial at −20°C for long-term stability and 2–8°C for short-term handling. Protect from light and avoid repeated freeze-thaw cycles. Compound-specific stability data is printed on the certificate of analysis supplied with the lot.
