TB-500 (Thymosin Beta-4): A Research Peptide Overview

TB-500 is a widely studied research peptide in the recovery and regeneration category, often researched alongside BPC-157. This overview explains what it is, the pathways it's associated with, and how to source it for laboratory work.

What is TB-500?

TB-500 is a synthetic 17-amino-acid fragment of Thymosin Beta-4, a naturally occurring protein involved in cellular processes. The synthetic fragment is stable and well-suited to controlled research.

Research pathways

  • Cell migration and actin regulation research.
  • Tissue-repair and regeneration research models.
  • Angiogenesis research in laboratory settings.

Formats & blends

TB-500 is available in lyophilized and activated forms: Thymosin Beta-4 / TB-500 (10mg). It is also a core ingredient in popular research blends:

TB-500 and BPC-157

TB-500 is frequently studied together with BPC-157, since the two are associated with complementary recovery-research pathways — which is why they're paired in the Wolverine blend. For more on the companion compound, read our BPC-157 overview.

Handling, reconstitution & purity
