TB-500 is a synthetic peptide of a protein that all humans have in their bodies. The natural protein occurs in cells and is called Thymosin Beta 4. This protein may have healing properties.

TB-500 may help speed up injury recovery. Some injuries and wounds could take several months or longer to heal on their own, TB-500 peptide may reduce that time.
