Verify a CoA before you trust it.
The short answer
To verify a peptide CoA, use the issuing laboratory's own verification system — never the PDF alone. Major labs offer task-ID + key verifiers or QR codes resolving on their domain. Check that the batch number on the certificate matches the product, the date is recent, and the report exists in the lab's system. No verification path = treat as unverified.
The principle
The document proves nothing; the lookup does
Anyone can edit a PDF, and forged CoAs attached to real lab names circulate in every gray market. The only meaningful check is a live lookup against the issuing laboratory’s own records. Three additional checks close the common loopholes: the batch number on the CoA must match the product in hand, the date must be plausibly recent, and the client name (where shown) should make sense for where you bought it.
By laboratory
Where each lab's verification lives (as published, August 30, 2026)
- Janoshik: verification page on their site — enter the task number and unique key from the report, or scan the QR on the PDF.
- Chromate: QR-based verify portal linked from reports.
- Iberian Analytical (from launch): every CoA carries a task ID and QR resolving to its permanent public database entry — and because publication is mandatory, absence from the database is itself disqualifying: a CoA that is not in the database is not ours.
- Labs without a public verifier: email the laboratory directly quoting the report number and ask them to confirm issuance — legitimate labs answer this routinely.
When it fails
If the CoA does not verify
Do not negotiate with the document. A failed lookup means one of: forged report, altered report, or a real report for a different batch. In all three cases the honest next step is the same — treat the product as untested, and if the stakes justify it, commission your own test on the actual vial in hand.
FAQ
Common questions
How do I know if a CoA is real?
Look it up in the issuing laboratory's own verification system using the task or report number printed on it. Then confirm the batch number matches your product and the date is recent. A certificate that only exists as a PDF, with no way to check it against the lab, should be treated as unverified.
What if a vendor refuses to give the report number?
A report number is not sensitive — it is printed on every legitimate CoA. Refusal to provide something that costs nothing and enables verification is itself the answer.
Iberian Analytical opens in Q1 2027 — €99 per test, 48–72 h target, and every result published in a public database, mandatory and free. Nothing is sold on this site today. Leave an email and we will write once, when the laboratory starts issuing certificates.
