Its cytoprotective mechanisms in this context are multifaceted: it bypasses the prostaglandin pathway, maintains endothelial integrity to ensure blood flow to the mucosa, and directly stimulates the cellular processes required for repair

Daily injection at one site for 4 weeks creates a hardened nodule of scar tissue that reduces peptide absorption by the second week
