TB-500 is a synthetic fragment of thymosin beta-4, a protein your body uses for tissue repair. First studied in veterinary medicine, it is now widely researched for human tissue repair and inflammation reduction. The fragment retains the healing and anti-inflammatory properties of the full protein while being more stable. Banned by WADA for its performance-enhancing effects.

How it works

TB-500 injection provides systemic distribution for whole-body tissue repair. It regulates how cells move and rebuild tissue, promotes blood vessel formation, reduces inflammation, and activates stem cell differentiation for accelerated healing.

Key benefits

  • Systemic tissue repair across muscles, tendons, ligaments, and organs
  • Reduces inflammation throughout the body
  • Promotes blood vessel formation for thorough healing
  • Enhances cell migration to injury sites
  • Activates stem cell differentiation for accelerated recovery
