GHK-CU

GHK-Cu is a naturally occurring copper-binding peptide found in human plasma, urine, and saliva. It is investigated in research for its role in tissue repair and cellular maintenance pathways. In laboratory and animal models, GHK-Cu is studied for its potential to influence wound healing, immune signalling, and skin biology, including its interaction with collagen production, fibroblast activity (cells involved in tissue repair), and angiogenesis (the formation of new blood vessels). It is also examined for its possible function as a damage-response signalling molecule and for its antioxidant activity in experimental systems.
