GHK-Cu is an endogenous copper-binding tripeptide naturally found in human plasma, saliva, and urine. Its concentration declines significantly with aging. In research settings, it has been studied extensively for its role in wound healing, collagen synthesis, and gene expression modulation.
A substantial body of in vitro and in vivo research supports GHK-Cu's role in wound healing and skin remodeling. Multiple published studies demonstrate accelerated wound closure in animal models. Microarray studies show upregulation of tissue repair pathways.
