TB-500

Thymosin Beta-4 fragment for systemic tissue repair and recovery.

TB-500

Overview

TB-500 is a synthetic version of the active region of Thymosin Beta-4, a naturally occurring peptide found in nearly every human and animal cell. It is studied for its role in cellular migration, blood-vessel formation, and tissue regeneration across muscle, tendon, cornea, and cardiac tissue.

Mechanism of action

TB-500 binds to and sequesters G-actin, regulating cytoskeletal reorganization. This enables cell migration to injury sites, promotes new blood-vessel growth (angiogenesis), and modulates inflammation by reducing inflammatory cytokine activity.

Reported benefits

  • Accelerated recovery from muscle, tendon, and ligament injury
  • Improved flexibility and reduced muscle spasm
  • Enhanced wound healing and reduced scar tissue
  • Cardiovascular tissue repair in animal models
  • Systemic anti-inflammatory effects

Research dosing

Typical research protocols: 2–5 mg per week, often split into two subcutaneous injections. Loading phase of 4–6 weeks, then maintenance at lower frequency.

Considerations

Effects are systemic — not just localized to injection site. Often combined with BPC-157 for compound regenerative effects. Generally well-tolerated in research settings.

Frequently stacked with BPC-157 for compound healing protocols.
