GHK-CUGHK Cu (Glycyl L Histidyl L Lysine Copper) is a naturally occurring copper binding peptide found in human plasma and other bodily fluids. It has been studied extensively in laboratory settings for its potential role in cellular regeneration, skin biology, and gene regulation. Research has explored GHK Cus involvement in processes such as collagen synthesis, wound healing, and oxidative stress response. Its activity has also drawn interest in studies
