GHK-CU stands out because it is primarily associated with collagen research, skin health investigations, cosmetic science, and regenerative biology
Stem cells and exosomes may protect neuron function by many mechanisms including releasing neurotrophic growth factors, regulating glial cell activity, enhancing BDNF activity, shutting off neuroinflammatory signals, controling cell turnover and cell death, downregulating formation of plaque, gliosis, and scar, and upregulating microRNA expression signals for neural repair (13) (14) (15) (16) (17) (18)
It has been found to stimulate collagen production, enhance wound healing, reduce scar formation, and improve skin elasticity
