What TB-500 is

Repair peptide, plain

A synthetic version of the active piece of your body's own repair protein.

BPC-157's tag-team partner.

Your body has a built-in repair protein, and TB-500 is basically the lab-made highlight reel of it.

(A peptide is a short chain of the building blocks your body uses.) Your body makes a protein called Thymosin Beta-4 that's involved in patching things up. TB-500 is a synthetic version of its active piece, studied for the repair-and-recovery side.

It lives on the Healing + Recovery shelf next to its usual partner, BPC-157.

What it actually does

Picture a construction crew that needs to reach a job site fast. TB-500 is studied for how it helps cells move and how new supply lines (blood vessels) form, the logistics of repair.

That's the mechanism researchers keep circling: cell movement and the plumbing that supports repair. We're describing what gets studied, not promising it fixes anything of yours.

The research so far

TB-500 is one of the most-researched repair peptides next to BPC-157. You can read the full chemical profile on its PubChem entry.

Cell migration

Getting repair cells where they're needed.

Angiogenesis

New blood-vessel formation.

Research only

The backstory

TB-500 comes from the active region of Thymosin Beta-4, a protein the body uses in repair.

  1. From Thymosin Beta-4

    Built from the active fragment of the body's repair protein.

  2. Paired with BPC-157

    The two come up together constantly in recovery research.

  3. Where it stands

    Some of the deepest tissue-repair research in the peptide space. We're not telling you what it does for you, just where the studies look.

What is TB-500?
TB-500 is a synthetic fragment of the repair protein Thymosin Beta-4, studied in tissue-repair research for how it relates to cell migration and blood-vessel formation. Sold as a lyophilized powder for research use only.
What is the molecular weight of TB-500?
TB-500 has a molecular weight of 889.0 g/mol and the molecular formula C38H68N10O14 (PubChem CID 62707662).
How is the purity verified?
Every batch is tested by HPLC to at least 99% purity, and the Certificate of Analysis for that batch ships with the order and is shown on the product page.
How should it be stored?
Store the lyophilized powder cold and protected from light. Keep it sealed until use to maintain stability.
Does it come with a COA?
Yes. Every batch ships with its Certificate of Analysis, shown right on the product page, so you can confirm purity before you buy.
What does "research use only" mean?
It means this product is intended strictly for laboratory research. It is not for human or animal consumption, and nothing on this page is a medical or therapeutic claim.

Not for human consumption. Not approved by Health Canada. For in vitro research only.
