It suppresses the NF-B inflammatory pathway directly inside cells without systemic immune suppression, without the side effects of steroids, and without melanocortin receptor activation

This age-related decline correlates with diminished wound healing capacity, reduced collagen synthesis, and compromised tissue regenerationobservations that sparked decades of research into GHK-Cu's role in aging and tissue maintenance

Biological Effects of a Novel Multifunctional GHK-Cu Loaded Wound Dressing International Journal of Pharmaceutics GHK-Cu-loaded wound dressings accelerated full-thickness wound closure in rats by 40% vs controls, with enhanced collagen synthesis, angiogenesis, and earlier expression of wound-healing cytokines
