GHK-Cu 50 MG

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) at 50 mg provides researchers with a mid-range quantity of this historically significant tripeptide-metal chelate, suitable for focused experimental programs and pilot studies. Discovered in the 1970s as a component of human serum that declined with age, GHK-Cu has since been subjected to rigorous investigation across multiple scientific disciplines. The peptide portion binds copper(II) ions with high affinity through its histidine and glycine residues, forming a stable complex that has shown remarkable activity in gene expression studies across many cell types.
