TB-500

TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring peptide. In research it is studied for its role in actin regulation, cell migration, and tissue-repair pathways. Supplied for laboratory research use only — not for human consumption.

This compound is analyzed by a third-party lab using HPLC for purity and mass spectrometry for identity, with the Certificate of Analysis available on the product page (verifiable at janoshik.com) so researchers can verify it independently.

Freeze-dried TB-500 is generally stored cold (refrigerated or frozen) and protected from light and moisture; after reconstitution it is kept refrigerated and used within a shorter window, per your lab's handling protocols.

Yes. Peptide Depot supplies TB-500 in Canada strictly for laboratory and research use. It is not approved for human or veterinary use and is not intended for consumption.

Both are peptides studied in tissue-repair research, but they are structurally unrelated and act through different pathways — TB-500 is a thymosin beta-4 fragment studied for actin regulation and cell migration, while BPC-157 is a gastric-juice-derived fragment studied for angiogenesis and connective-tissue models. Our "BPC-157 vs TB-500" article covers the comparison in more depth.
