Research Use Only – This content is for scientific research and educational purposes only. GHK-Cu is not approved for human consumption or therapeutic use.
GHK-Cu (Glycine-Histidine-Lysine Copper Peptide) is a naturally occurring tripeptide-copper complex studied for its effects on collagen synthesis, wound healing, and tissue remodeling in preclinical research models.
Mechanism of Action
In preclinical research models, GHK-Cu is studied with the following theoretical mechanisms:
GHK-Cu is studied for its role in promoting collagen synthesis and tissue remodeling through multiple signaling pathways. Research indicates it may upregulate growth factors including TGF-β, increase angiogenesis, and modulate matrix metalloproteinase activity. The copper component is theorized to enhance enzyme cofactor activity and oxidative balance in tissue repair systems.
