GHK-Cu is a naturally occurring copper-binding tripeptide complex consisting of the peptide glycyl-L-histidyl-L-lysine chelated to a copper (II) ion, found endogenously in human plasma, saliva, and urine. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only. Research ContextGHK-Cu is studied as a subject of interest across multiple converging molecular pathways in in-vitro and animal-model research. Investigations have examined its association with gene-expression modulation, reporting influence on over 4,000 human genes in research models. It is studied in research into collagen, elastin, and glycosaminoglycan biosynthesis pathways, VEGF-associated angiogenesis signalling, and antioxidant and inflammatory-pathway activity via superoxide dismutase induction. Its copper-chelating properties are examined in research into extracellular-matrix and connective-tissue biology, and its documented association with TGF-β signalling and stem-cell activation makes it a subject of interest in skin-biology, hair-follicle, and matrix-remodelling pathway research.Specifications• Sequence: Validated by mass spectrometry (MS/MS)• Purity: ≥ 99% by HPLC• Form: Liquid• Molecular Weight: 340.4 Da (free peptide); 403.9 Da (copper complex)• Storage: 2 – 8 °C, keep dry and away from light• Shelf Life: 24 months from manufacture date (sealed)Quality & TestingEvery batch is independently tested by a certified third-party laboratory.
