TB-500 is a synthetic peptide fragment of thymosin beta-4, a naturally occurring 43-amino-acid protein involved in cell migration, differentiation, and tissue repair. Research in animal models has demonstrated its role in promoting angiogenesis, reducing inflammation, and upregulating actin — a cell-building protein critical to wound healing and tissue regeneration.
