TB-500 is a synthetic peptide that corresponds to the active region of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid protein found in high concentrations in blood platelets and wound fluid. The Tβ4 protein plays a central role in actin sequestration and cell migration. TB-500, as the 17–23 fragment, retains much of Tβ4's biological activity and is researched for its potential to accelerate wound healing and reduce inflammation. It has gained traction in sports medicine research circles, though no human clinical trials have been published.
