What they found that, at least for the gastrointestinal tract, oral administration of BPC 157 seems to be favorable Pentadecapeptide BPC 157 and the central nervous system (link) This great study was designed to look at the effectiveness of BPC-157 on things like Behavioral Disorders, Brain Lesions, and Spinal Cord Injury

Accelerates wound healing through growth factor modulation Stimulates angiogenesis (formation of new blood vessels) to injured areas Promotes fibroblast activity and collagen formation Protects endothelial function and blood flow Reduces systemic and local inflammation without NSAIDs or corticosteroids Heals tendon-to-bone junctions and muscle strains that are notoriously slow to regenerate BPC-157 improves functional recovery by increasing VEGF expression, enhancing angiogenesis, and accelerating fibroblast migration and collagen deposition.
