GHK (glycyl-L-histidyl-L-lysine) is a naturally occurring tripeptide supplied for in vitro research. It is studied in published literature for its copper-binding properties and interactions with extracellular matrix components and cell signalling pathways. The copper complex (GHK-Cu) is used in dermal and cosmetic science research. This 50 mg format is suitable for in vitro and topical research applications. Supplied as lyophilised powder with certificate of analysis. For research use only — not for human or animal consumption.

Every batch is verified at the manufacturer and re-tested when received in the UK. We send batches to a third-party lab where results cannot be manipulated — we do not rely on supplier testing or CoAs alone, so you get what you pay for. Each batch is independently analysed and supplied with a Certificate of Analysis (CoA) detailing purity, identity, and analytical method used. Batch-coded stock ensures full traceability from production to dispatch. Stock is held in laboratory-grade temperature-controlled storage and prepared using controlled thawing before dispatch. See our About page for full details. Additional documentation is available upon request for institutional procurement.
