Synthetic fragment of thymosin beta-4 used in actin-binding and cell migration assays.
Third Party Tested by Freedom Diagnostics









Published research data and clinical observations
TB-500 is the active fragment of Thymosin Beta-4 — a protein found in every nucleated cell. It works by reorganizing the cell's internal skeleton (actin), which controls how cells move to injury sites and build new tissue.
Most growth factors only work locally at the injection site. TB-500's small molecular weight lets it travel systemically through tissues:
Promotes cell migration to injury sites regardless of injection location — 61% faster wound closure at day 7 vs controls.
