GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring tripeptide-copper chelate with a molecular weight of approximately 403.93 g/mol. GHK-Cu binds copper(II) ions with high affinity and is studied in vitro for its interaction with extracellular matrix protein expression, metalloproteinase regulation, and copper-dependent enzyme activation in cell culture models. Research applications include cell culture studies examining fibroblast proliferation, glycosaminoglycan synthesis, and matrix remodeling enzyme kinetics. For in vitro research use only. Not for human or veterinary use.
