Synthetic fragment of Thymosin Beta-4 studied for cellular repair and migration.
TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (TB4), a naturally occurring protein. It is studied for actin regulation, cell migration, and wound healing — and is the most common stack partner for BPC-157 in recovery research.
TB-500 is a synthetic peptide fragment of the naturally occurring protein Thymosin Beta-4 (TB4). Preclinical research focuses on its role in actin regulation, cell migration, and wound-healing pathways.
TB-500 binds actin and is implicated in cell migration, proliferation, and the upregulation of repair-related signaling in injured tissue.
