Scientific overview
GHK-Cu is a naturally occurring copper-binding tripeptide that modulates expression of ~4,000 human genes. Upregulates collagen synthesis (COL1A1, COL3A1), stem cell markers, and antioxidant enzymes while suppressing inflammation-associated genes. Plasma levels decline from ~200 ng/mL at age 20 to ~80 ng/mL by age 60.
