How It Works

TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide present in virtually all human cells. It plays a crucial role in tissue repair by promoting cell migration, blood vessel formation, and regulation of actin (a cell-building protein). Its unique molecular structure allows it to travel long distances through tissues.
