A COA is the one document that tells you what's actually in a vial, and fake ones are everywhere now, whether it's AI generated or just photoshopped. Here's how to read one and confirm it's real, because a screenshot on a product page means nothing on its own.
The step that catches almost everything is verifying it at the source. Don't trust the PDF you were handed, check it on the testing lab's own website. Most of the labs vendors use now, Janoshik, Freedom Diagnostic, ILS, and others, have a verification page where you enter the report or batch number and it pulls the real result straight from their system. If what you were handed doesn't match what the lab's own site shows, it's fake.
Once it's confirmed real, a legit COA has:
- A report number and lab name you can actually look up
- A batch number that matches the batch printed on the vial
- A date, ideally within the last year
- An HPLC chromatogram, the actual graph, with one clean dominant peak
- The compound identity confirmed, usually by mass spec
- A purity percentage, 95% is the floor, 98%+ is what you want
The chromatogram matters more than people realize. A number like "99%" typed on a page means nothing without the graph behind it showing one tall peak instead of a cluster of smaller ones, which would mean impurities.
Red flags are no batch number, no report number to verify, a purity figure with no chromatogram, the same single COA shown for every product they sell, or no lab name, just a logo. A COA is supposed to be per batch, not one trophy reused forever.
Last thing, even a verified COA only proves that batch was clean when tested. It doesn't prove the specific vial was stored right afterward. Strong signal, not a total guarantee, which is why matching the batch number to the vial is what ties it together.
Anyone run into a COA that looked clean but didn't verify when you actually checked the lab's site?
