Know what you’re looking at

Better questions start
with a clearer document.

Work through the paperwork without confusing a lab result with a safety verdict.

01 / READ THE REPORT

Make sense of every field.

Lot numbers, testing methods, dates, results, and acceptance ranges—explained in plain language.

Read a COA
02 / CHECK THE SOURCE

A convincing PDF isn’t proof.

Find the issuing lab independently and check that the report and the lot belong together.

Follow the verification steps
03 / KNOW THE LIMITS

One report. A defined scope.

A COA does not establish FDA approval, handling history, or whether a treatment is right for you.

Understand what it can’t prove

A practical place to start

Follow the evidence.
Not the logo.

Appearance alone cannot establish authenticity. Use these five steps to ask better documentation questions.

Clarity before conclusions

A few important
distinctions.

Read our source-verification standard
What does a COA actually show?
A Certificate of Analysis reports the tests performed on a specific lot, their results, and the specifications used. Not every COA covers the same tests. Learn the basics.
Does it mean a product is FDA approved?
No. A COA is a testing document. It does not confer or imply FDA approval of a drug, indication, or compounded preparation.
Why can’t I browse records yet?
Public display remains paused during source-verification review. No record is published before confirmation with its source. You can use the educational guides now.
Who can submit a certificate?
The current submission route is for pharmacies. Patient and provider submission routes are planned, but are not available yet. See the pharmacy requirements.
