This comparison does not assign a generated winner or score.

  • Origin
  • Human gastric juice protein
  • Thymus gland protein (found in all cells)
  • Size
  • 15 amino acids
  • 43 amino acids (active fragment)
  • Primary Mechanism
  • Angiogenesis / VEGF upregulation
  • Actin regulation / Cell migration
  • Key Target
  • Restores blood supply to damaged tissue
  • Promotes cell migration to injury sites
  • Nitric Oxide
  • Modulates NO system directly
  • Indirect NO involvement
  • Anti-Inflammatory
  • Moderate (reduces inflammatory markers)
  • Moderate (downregulates inflammation)
  • Gastric Effects
  • Strong gastroprotective activity
  • Minimal gastric activity
  • Systemic Distribution
  • High — effective regardless of administration site
  • High — distributes systemically
  • Tendon/Ligament
  • Strong evidence for tendon healing
  • Strong evidence for tendon and ligament repair
  • Cardiac Research
  • Cardioprotective in multiple models
  • Cardiac repair after ischemic events
  • Published Studies
  • 100+ preclinical studies
  • Extensive Tβ4 research (fewer TB-500 specific)
