THAI BIO LABS TB-500 10 mg research vial with white cap

TB-500

Material identity · analytical research

TB-500 requires particular care with material identity. The name should not be treated as proof that a preparation contains full-length thymosin beta-4 or any particular fragment.

Not currently supplied

This compound is not currently supplied by TBL. Contact us about availability; no release date is confirmed.

Evidence Brief

Material identity · analytical research

Selected research context

Esposito and colleagues (2012) identified an acetylated 17–23 fragment of thymosin beta-4 in a product named TB-500 using chromatography and mass spectrometry.

What this evidence does not establish

The paper characterises the tested sample, not every product carrying this name. Full-length thymosin beta-4 findings cannot automatically be assigned to that fragment or an unidentified preparation.

Original source

Selected reference checked 3 November 2026. This is an introductory reading guide, not a systematic review of all published evidence.

Read the evidence and the material record separately

Published research describes a specific material, model and study design. It does not certify the identity, purity or quality of a supplied vial. Compare the exact chemical form or peptide sequence, then review the study population, controls and endpoints. Any future TBL supply would require its own matching lot documentation and a separate release decision.

For research reference only. No medical advice, dosing or human-use guidance is provided.
