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 6 month GHK CU check in Main takeaway: skin transformation takes time. GHK CU peptide binds to copper and activates genes involved in wound healing, collagen synthesis, and skin remodeling.
