Buying TB-500 on the strength of a lab report only makes sense if you can read the report yourself. This page transcribes Janoshik task #93627 for our TB-500 10mg vial, field by field, and explains what the numbers mean for your order.

What you’re getting, according to the lab
Janoshik found 10.84 mg of material in a vial sold as 10 mg, so the vial came in above its label rather than under it. Purity came back at 99.165%. Both figures describe one sample the lab received on December 11, 2025 and analyzed four days later. They describe that lot, not every vial we will ever ship.
You’ll see the analyte listed as “TB-500 (TB4)”. That’s the lab’s naming convention. For a side-by-side of the 43-residue thymosin beta-4 protein and the short TB-500 fragment, see TB4 vs. the TB-500 fragment.
What the report leaves out
- No method line: column, gradient and detection wavelength aren’t printed.
- No sterility or endotoxin result, because neither test was ordered.
- No batch code. The batch field says “Unknown” and the sample is identified by photos the lab took on arrival.
Checking your vial against it
We don’t print batch numbers on vials. Instead, the cap color and crimp color link each vial to its certificate. Note both colors when your package arrives and compare them with our posted reports; if they don’t line up, contact us before opening the vial.
