GHK-Cu: collagen and structure GHK-Cu is a copper-binding tripeptide associated with regulation across more than 4,000 genes, including collagen synthesis, antioxidant defense, wound healing, inflammation, and tissue breakdown. Circulating levels decline with age, from roughly 200 ng/mL at age 20 to about 80 ng/mL by 60.
