Recovery TB-500

Premium TB-500 for tissue repair research

TB-500 — a thymosin beta-4 related research peptide — studied in actin and cell-migration models.

TB-500

Research overview

TB-500 is a synthetic version of a fragment of thymosin β-4 — a 43-amino-acid protein your body naturally produces in most tissues. The full protein helps control how cells move during wound healing by binding to actin (a structural protein inside cells). What's sold as "TB-500" is often just a key active piece of the full molecule, not the whole thing. A pharmaceutical company (RegeneRx Biopharmaceuticals) tried to develop the full-length version (called RGN-352) as a real drug — testing it in heart failure and wound healing — but discontinued development before completing Phase 3 trials. What's sold online for "research" bears no FDA approval and no manufacturing oversight.
