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

Research indicates that GHK-Cu can increase collagen production by up to 70% in laboratory studies
