The practical takeaway: Injection = high systemic distribution tendons, ligaments, muscle, joints, vascular tissue Oral = high local GI concentration intestinal lining, gastric mucosa, gut repair Nasal = intermediate systemic delivery potential neurological targeting, emerging evidence only Injectable BPC-157: Highest Bioavailability for Systemic and Musculoskeletal Goals Injectable BPC-157 is the best-studied delivery method for healing applications outside the gastrointestinal tract

The standard reconstitution fluid for peptides, allowing multi-dose vial use over weeks
However, BPC 157 is relatively stable and small dose ranged between ng-g/ml or ng-g/kg is already effective on promoting tissue injury healing and angiogenesis in many animal studies 4,27,28,29,30
