Certificate of analysis
Every vial ships with its own report
We don't publish a brand-wide spec sheet and call it a “COA.” The certificate you receive references the actual lot number stamped on your vial — with the raw chromatograms attached.
- Lot-specific HPLC purity + LC-MS identity
- Raw chromatogram + mass confirmation attached
- Signed off by the lab's Principal Chemist

The process
How every batch is verified
Four steps, every lot. The certificate is published before the vial ships.
01Made in a controlled facility
Documented, repeatable steps for every batch.
02Purity tested
An outside lab measures it and reports the exact number.
03Identity confirmed
A second test proves it is what the label says.

How TB-500 works
Researchers study TB-500 through three main routes tied to how thymosin beta-4 supports repair.
01
Cell migrationactin binding
It's studied for helping cells move toward injured tissue by influencing actin, the internal scaffold cells use to crawl and reorganize.
02
Angiogenesisblood vessel growth
Preclinical work links it to the formation of new blood vessels, which could support tissue that's rebuilding after damage.
03
Tissue repairwound healing
It's investigated for its role in wound closure and remodeling, echoing what the parent protein does at injury sites.

Every batch we've tested
Anyone can show you one good report. Here is every batch of TB-500 we have ever released, newest first, each with its own signed report. Nothing hidden, nothing cherry-picked.
