Frontiers Exploring the beneficial effects of GHK Cu on an experimental model of colitis and the underlying mechanisms Reactive oxygen generation by minimal copper binding peptide motifs bioRxiv Viral claim says GHK Cu reset nearly 4,000 genes to a younger state and increased collagen production in a preclinical study. This refers to research on GHK Cu, a naturally occurring copper binding peptide that How GHK Peptide Works Signaling GHK acts as a switch for skin repair: Interacts with adenosine receptors reduces inflammation Activates MAPK ERK, PI3K Akt, TGF pathways Stimulates fibroblasts & keratinocytes boosts collagen, elastin The Bright and Dark Sides of Reactive Oxygen Species Generated by CopperPeptide Complexes
