What Is GHK-Cu?

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide found in human plasma. It was first identified in the early 1970s and has since become one of the most studied peptides in the longevity and skin health space. This is the same compound available in our raw powder and hair serum, now in a pre-measured 2mg capsule for daily convenience.
