How to Verify a Peptide COA on the Lab's Own Portal

The one rule: don't trust a PDF the vendor hands you — confirm the result on the testing lab's own website. A real lab lets you look up a report independently; a fake one can't. Here's how to do it in under two minutes.

Step by step

  1. Find the lab name + report/verification number on the COA (usually near the header or footer).
  2. Go to the lab's own website directly — type it in yourself, don't use a link on the vendor's store (a fake "portal" can be hosted by the vendor).
  3. Use the lab's lookup/verify tool and enter the report number.
  4. Check what comes back: a genuine portal returns a specific, server-rendered record that matches the PDF — same compound, same purity, same date.

The fake-portal test

Before you trust any "verify" page, type in a made-up, random number. A real portal returns nothing (or an error). A fake one returns a valid-looking "OK" for anything — which means it's theatre, not verification.
