GHK-Cu supplies a high-affinity copper-binding tripeptide complex (glycyl-L-histidyl-L-lysine chelated with divalent copper Cu2+), verified at ≥99% purity by analytical HPLC and mass spectrometry. In laboratory investigations, GHK-Cu is characterized for its role in cellular signaling, fibroblast modulation, and extracellular matrix remodeling pathways, particularly the regulation of collagen I, III, and metalloproteinase balance. Lyophilized under inert nitrogen to preserve chelation integrity. Supplied strictly for laboratory research. Not for human or veterinary use.

Laboratory Handling & Solvent Protocols

To preserve structural integrity and peptide purity, lyophilized materials should be maintained at -20°C in an airtight container protected from ambient moisture and light. Reconstitution should be conducted under sterile conditions using bacteriostatic water (0.9% benzyl alcohol) or sterile laboratory saline. Allow the diluent to run gently down the interior vial wall; avoid vigorous shaking or vortexing to prevent shear-induced degradation. Reconstituted aliquots must be stored at 2°C to 8°C and evaluated within 28 to 30 days.
