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
Find the lab name + report/verification number on the COA (usually near the header or footer).
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).
Use the lab's lookup/verify tool and enter the report number.
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.
Pass vs. fail
✅ Pass: the report resolves on the lab's own domain, matches the PDF, and names the vendor as the client.
❌ Fail: no portal, a portal on the vendor's own site, a portal that accepts fake numbers, or a record that doesn't match the PDF.
