GHK-Cu

GHK-Cu (Copper Peptide) is a naturally occurring tripeptide complex consisting of glycine-histidine-lysine bound to a copper ion. This small but powerful peptide is found naturally in human plasma, saliva, and urine, with levels declining with age. In research contexts, GHK-Cu is extensively studied for its multifaceted biological activities including wound healing promotion, collagen synthesis stimulation, antioxidant properties, and effects on gene expression. Scientists investigate its role in tissue remodeling, extracellular matrix production, anti-inflammatory responses, and cellular regeneration. The copper binding enhances its biological activity and stability. Research applications include studies on skin tissue repair, collagen and elastin production, antioxidant enzyme activation, and metalloproteinase regulation. The compound is particularly valuable in cosmetic science research and regenerative medicine studies focused on tissue repair mechanisms and age-related decline in regenerative capacity.
