TB-500 is a synthetic peptide version of the naturally occuring healing protein present in about all human and mammalian cells known as Thymosin Beta 4 (TB4). Research has shown TB 500 to have beneficial effects on wound healing, injury recovery, flexibility, and inflammation. These desirable effects are accomplished through TB 500’s influence on blood cell and blood vessel development, cellular differentiation, and cell migration. A major part of its healing capability stems from the peptide’s regulation of actin, a cell building protein essential to healing and wound repair.
