A synthetic peptide related to thymosin beta-4, studied in preclinical models of tissue repair.
TB-500 is a synthetic peptide fragment related to thymosin beta-4, a protein naturally found throughout the body that plays a role in cell migration, tissue repair, and blood vessel formation. It has been studied primarily in animal models of injury and recovery.
TB-500 is not FDA-approved for any human or veterinary use. It has not completed human clinical trials establishing safety or efficacy, and is classified as a research chemical intended solely for laboratory and preclinical research settings.
