The complementary mechanisms create a multi-phase healing support system: early cytoprotection and inflammation control (all three peptides through distinct pathways), proliferative phase support including angiogenesis (triple-pathway vascular stimulation), cellular coordination, and matrix formation (TB-500 and GHK-Cu), structural integration through periosteal activation and stem cell recruitment (BPC-157), and remodeling phase regulation preventing fibrosis while supporting functional tissue architecture (TB-500's antifibrotic effects and GHK-Cu's MMP regulation)
