GHK-Cu is a copper complex of the tripeptide glycine-histidine-lysine. It is one of the most recognizable copper-peptide references in literature around extracellular matrix biology, copper signalling, gene-expression models, and tissue-remodelling pathways.
The reason customers look at GHK-Cu is the copper-bound structure. Copper coordination gives the peptide a different analytical and biological context than the free GHK sequence, so appearance, complex notation, and purity matter more than the name alone.
This product is best understood as a copper-peptide research material for matrix and cell-signalling studies. It is not positioned as a cosmetic product; the useful information is the mechanism literature plus the product specification table.
The references below are starting points for the mechanisms discussed here. The specification table on this page covers identity, formula, molecular mass, physical form, solubility, storage, and lot-level analytical information.
