Third-Party Verified
Every batch.
Every test.
Public.
Most peptide brands hide their lab work. We post ours. Every batch is HPLC tested by an accredited third-party laboratory before it ships — purity, lab, batch number, and test date are all here.

Our Process
How a vial gets a certificate.
01
Source
We work only with cGMP-grade synthesis partners. Every kilogram lands sealed and lot-tracked, with the supplier's own internal CoA on the box.
02
Sample
A vial from each batch is pulled at random and sent to a third-party laboratory. We do not test our own product — we don't think anyone should.
03
Verify
The lab runs HPLC (high-performance liquid chromatography) and reports the purity percentage, the trace, and the batch number on a signed PDF. We publish it here.

What buyers ask before they trust us.
What is a Certificate of Analysis?
A signed PDF from an independent laboratory documenting what's in a vial. The lab runs HPLC, measures purity to two decimal places, and certifies the result with their name, stamp, and date. If a brand doesn't have one — or won't show it — assume nothing's in the vial.
What does '99%+ purity' actually mean?
It means the chromatograph shows no other peaks above 1% relative area. We don't ship anything below 99%. If a batch comes back at 97%, it doesn't make it onto the site — the supplier eats the cost.
How often do you test?
Every kilogram of every compound, every time. New batch in, new sample out, new CoA published. Same vial you receive is pulled from the same batch the certificate covers.
Can I verify a specific batch number?
Yes. Match the batch on your vial label to the batch number on the certificate above. If you can't find it, email support@veridianbio.com with the batch number and we'll send you the PDF directly.
Don't see your batch?
If you ordered a compound and want the exact PDF for the batch you received, email us with the batch number on your vial. We'll send it back within the day.
