GHK-CU

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding peptide composed of three amino acids: glycyl-L-histidyl-L-lysine. It has been identified in human plasma, saliva, and urine, and has been widely studied in scientific research for its potential role in cellular signaling, tissue remodeling, and regenerative processes.(1) Researchers have explored GHK-Cu for its apparent involvement in supporting collagen synthesis, extracellular matrix activity, and skin-related research models.

Studies have also suggested that GHK-Cu may exhibit antioxidant properties and influence pathways associated with wound healing, hair follicle activity, and overall tissue maintenance.(2) Due to its broad range of investigational applications, GHK-Cu continues to be a peptide of significant interest within cosmetic, dermatological, and regenerative research settings.
