  • Primary mechanism
  • VEGFR2/angiogenesis, NO modulation
  • Actin sequestration, cell migration
  • Best application
  • Localized injury, gut healing
  • Systemic repair, muscle regeneration
  • Human trials
  • 3 pilot studies (under 30 subjects)
  • Phase I, II, III (100+ subjects)
  • FDA status
  • Category 2 (restricted)
  • Not scheduled
  • WADA status
  • Prohibited (S0)
  • Prohibited
  • The pharmacokinetic difference explains why these peptides are dosed so differently. BPC-157 peaks fast and clears fast. TB-500 peaks later and lingers.
