GHK-Cu research peptide is supplied to qualified Canadian institutions as a characterized laboratory material for in vitro copper-coordination, extracellular-matrix, and gene-expression studies. The compound is the copper(II) complex of the plasma tripeptide glycyl-L-histidyl-L-lysine (copper tripeptide-1).

In vitro, copper coordination is integral to the complex's behaviour in extracellular-matrix and transcriptional assays; free-ligand GHK (340.4 g/mol) is not interchangeable with the metal complex. Typical designs apply GHK-Cu to fibroblast or keratinocyte cultures and record matrix-protein transcripts, metalloprotease panels, or copper-dependent readouts, with GHK and copper-salt controls. This listing describes biochemical use in experimental systems only.

The material is offered lyophilized as a blue-tinted powder. Identity data (CAS 89030-95-5, formula C14H21CuN6O4, molecular weight 400.9 g/mol for the complex, PubChem CID 139035031) are listed on the specification table. Copper complexes are light- and moisture-sensitive: keep desiccated at −20 °C, protected from light, and handle under the receiving institution's chemical-hygiene plan.

Lots are sourced from a GMP-aligned peptide manufacturing partner and released against the stated HPLC purity for that lot (≥98% by HPLC, lot-specific). Identity, chromatographic purity, and related analytical results are documented on the lot certificate of analysis (COA). Retain the COA with the inventory record.

This listing is a research-use-only peptide offered to qualified Canadian institutions for in vitro and laboratory use. Purchasing access is limited to verified Canadian research institutions; individual consumer accounts are not accepted. It is not for human or veterinary use, is not intended for diagnostic procedures, and has not been evaluated or authorized by Health Canada as a drug, diagnostic, or medical product.
