What is TB-500?

TB-500 is the name research suppliers use for synthetic thymosin beta-4 (Tβ4), a naturally occurring protein found in almost every human and animal cell. Our vial contains the full 43-amino-acid sequence, acetylated at the N-terminus, at 4,963.5 g/mol (CAS 77591-33-4). Tβ4 binds actin, the protein cells use to move and change shape.

That actin role makes cell migration the main focus of TB-500 research, in wound, blood vessel and heart repair models. It’s also sold paired with BPC-157 in the Wolverine stack. Every lot is Made in China and tested by an accredited third-party lab, and it’s sold for laboratory research only. See the specs for our TB 500 peptide.
