What is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide first identified in human plasma. Concentrations of GHK-Cu decline with age, leading researchers to investigate its potential role in tissue maintenance, wound healing, extracellular matrix remodeling, and healthy aging.
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding tripeptide first identified in human plasma. Concentrations of GHK-Cu decline with age, leading researchers to investigate its potential role in tissue maintenance, wound healing, extracellular matrix remodeling, and healthy aging. Over several decades, GHK-Cu has become one of the most extensively studied regenerative peptides in the scientific literature. Research has explored its effects on collagen production, skin regeneration, wound repair, hair follicle biology, inflammation, antioxidant activity, stem cell signaling, and gene expression associated with tissue repair.
