Purivial Research Team · Updated June 2026 · 4 min read

TB-500 is a recovery peptide based on Thymosin Beta-4, and the natural partner to BPC-157. Here is how it works and what the research shows.

How TB-500 works

TB-500 is a synthetic fragment of Thymosin Beta-4, a protein involved in cell migration and tissue repair. It is studied for supporting recovery, flexibility, and reducing inflammation.

What the research shows

Like BPC-157, the strongest data is preclinical, with wide anecdotal use for recovery. It is most often used as part of a stack rather than alone.

Pairs with BPC-157

TB-500 is usually run with BPC-157. The two cover complementary parts of the recovery process, which is why they are sold and used together.

Sourcing verified TB-500

Quality varies widely between sellers. Every Purivial TB-500 vial ships with a batch-specific COA showing HPLC purity of 99 percent or higher and mass-spec identity, so you know what is in the vial before it leaves the lab.
