What research has studied about GHK-Cu
GHK-Cu is a copper-binding tripeptide made of glycine, histidine, and lysine complexed with a copper(II) ion. It occurs naturally in the body and its levels decline with age; in research it is studied for roles in tissue remodeling, matrix signalling, and cellular communication.
Laboratory research on GHK-Cu has examined effects on collagen and matrix-protein expression, antioxidant signalling, and wound-repair models in cell and animal systems, going back to the tripeptide's isolation from human plasma in 1973 — our research blog walks through what published GHK-Cu research has actually reported, study by study. These are preclinical observations reported in the literature; nothing here describes use in humans.
