Summary

TB-500 is a synthetic peptide related to the C-terminal region of thymosin beta-4, used in preclinical and experimental settings to explore wound-healing and muscle-repair pathways. Evidence is largely extrapolated from TB-4 biology and animal models, with limited direct human trial data. It is not approved for general medical use and is mainly studied in research contexts.
