GHK-Cu vs BPC-157: Tissue Repair Peptide Comparison

GHK-Cu and BPC-157 are both extensively studied in tissue repair research but operate through entirely different mechanisms. GHK-Cu is a copper-delivery tripeptide that modulates over 4,000 genes involved in ECM remodeling, collagen crosslinking, and antioxidant defense. BPC-157 works through NO signaling, VEGF upregulation, and FAK-paxillin cascade activation. Researchers compare these to select the repair mechanism best aligned with their tissue model.
