How to Spot a Fake or Edited Peptide COA

A certificate of analysis is only worth something if it is real and belongs to the lot in front of you. Recycled, borrowed and edited reports are common in this market, and they are easy to make look official.

No lab name, or a lab you cannot find anywhere. A real lab has a website, contact details and a history.

No lot or batch number, or the same report shown for every product or every batch a seller has ever stocked.

A test date that is very old for a product that sells out often. The material that report describes is probably long gone.

Numbers with no units, or results that are suspiciously perfect across every product.

Signs of editing: fonts or sizes that do not match, text that sits slightly off its line, cropped headers or logos, or a blurry screenshot instead of the original PDF.

A client or sample name on the report that has nothing to do with the product it is supposed to describe.

Many independent labs print a verification key or QR code on every report. Janoshik, for example, prints a unique key that anyone can enter on the lab's own website to see the original result. If a key is printed, use it and make sure the numbers match.

If there is no key, you can contact the lab directly with the task or report number and ask whether it is genuine.

Ask the seller which lot your order will ship from, and check that the report is for that lot.

Our reports come from Janoshik, an independent lab. Each product's figures are shown on its page with the full PDF one click away, and every certificate we hold is listed on our COA page.
