It facilitates cellular communication by binding copper ions, which activates metalloproteinases and growth factors involved in collagen and elastin production, DNA repair, and cellular proliferation
Where BPC-157 and TB-500 act primarily through actin/cytoskeletal and growth-factor pathways, GHK-Cu's mechanism is dominated by transcriptional reprogramming via copper-dependent gene regulation, making it a complementary research tool when investigators wish to dissect transcription-driven from structural-protein-driven repair phenotypes
