GHK-Cu Research Peptide

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. First isolated from human plasma, it has been the subject of four decades of research into skin remodelling, collagen synthesis, antioxidant defence and wound repair.

Noxptide GHK-Cu is synthesised to ≥99% purity and independently verified by HPLC and MS. Its characteristic deep-blue colour confirms proper copper chelation — a simple visual marker of quality that cheaper, poorly chelated material fails to show.

Supplied lyophilised in sterile vials with batch-specific Certificates of Analysis and full traceability.
