GHK-Cu
Copper Tripeptide
GHK-Cu is a naturally occurring copper-binding tripeptide that your body produces less of as you age. Between your twenties and your sixties, levels decline by over 60%. It plays a key role in collagen synthesis, tissue repair, and inflammation signaling. Replacing what your body used to make naturally is the core premise of GHK-Cu therapy.
How it works
GHK-Cu binds copper ions and delivers them to cells, activating pathways involved in collagen production, antioxidant defense, and tissue remodeling. Research shows it modulates the expression of over 4,000 genes, many related to wound healing, immune response, and inflammation. It promotes new blood vessel formation and increases production of decorin, a protein essential for skin structure.
