GHK-Cu Copper Peptide: What the Research Shows
GHK-Cu: What the Research Shows GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK), a small, naturally occurring peptide-copper chelate found in human plasma, saliva, and urine, whose concentration declines with age. The peptide has a well-characterized affinity for copper ions, and the GHK-Cu complex is one of the most extensively published copper-binding peptides […]
