GHK-Cu (Copper)

GHK-Cu is a naturally occurring copper-binding tripeptide found in plasma that declines with age (200 ng/mL at 20 years to 80 ng/mL at 60 years). It plays a crucial role in tissue repair, gene expression, and cellular regeneration. Research indicates applications in wound healing, skin regeneration, anti-inflammatory, antioxidant, and behavioral studies.
