TB-500 10mg
Thymosin Beta-4 (TB-500) is a naturally occurring 43-amino acid peptide present in nearly all mammalian cells. Research focuses on its role in cell migration, blood vessel formation, and modulation of inflammatory responses. TB-4 sequesters G-actin, promoting cell motility critical to wound repair.
