How it works
Step 01
Find your batch number
Check the vial label or order confirmation. If your vial doesn't show a batch, search by vendor or peptide instead — many records carry a lab-side identifier from the third-party test.
Step 02
Enter it above
Type or paste it and click Look Up. We'll check our database of verified batches from 3 labs.
Step 03
See the verdict
Purity, testing lab, date, and pass/fail. If we don't have it, we'll point you to the vendor's own COA library.
