Synthetic thymosin beta-4, the 43-residue actin-sequestering peptide; the same compound used in the BPC-157 / TB-500 blend. Supplied as a lyophilized powder, sealed under nitrogen, in a 3 mL clear borosilicate vial with a flip-off cap. Each production lot is assayed by an independent laboratory for purity by RP-HPLC and identity by ESI-MS; the lot number printed on the label resolves to that certificate.
