How to verify a Janoshik report

Janoshik Analytical is an independent laboratory that issues many of the reports attached to research peptides. Its reports include a way to confirm them with the laboratory itself — which is exactly the check that separates a verifiable document from a copy. Here is how to do it, and what the result does and doesn’t tell you.

What’s on the report

• Task number — a number near the top, such as #123456. It identifies the report.
• Client, sample, manufacturer and batch — the details as provided when the test was ordered.
• Results table — typically the compound name with a quantity, and purity.
• Dates — when testing was ordered, when the sample was received, and when the analysis was conducted.
• Unique key and QR code — at the bottom. The report says to verify the test on the laboratory’s website with that key.

How to verify it

1. Use the QR code or the printed key. The QR code opens the laboratory’s verification record for this report. Alternatively, go to the laboratory’s own verify page, as stated on the report, and enter the task number and key.
2. Open it yourself, in your browser. Don’t trust a link someone else typed for you — use the QR code on the document or the address printed on it.
3. Compare every field. The task number, client, sample name, batch, dates and results on the laboratory’s page should match your copy exactly.
4. Look at the details. A match on a different task number, or on a report for a different compound, is not a match.

What a match proves — and what it doesn’t

A match shows that:

• the laboratory issued a report with that task number and key, and
• its content matches your copy, so the document wasn’t altered afterwards.

It does not show that:

• the vial you hold is the sample that was tested — the batch label on a sample is provided by whoever ordered the test;
• any property that wasn’t tested is fine;
• the product is safe, legal or suitable for any use.

Public test listings are not verification

The laboratory also publishes a list of tests that sellers have chosen to make public. The titles and descriptions there appear to be supplied by the person who ordered each test (many read like seller marketing). A listing is a pointer to a report, not confirmation of a document you have: still check the task number and key on your copy.

How PeptideProof helps

When you upload a report with a QR code, PeptideProof reads it, checks that the link points to the laboratory’s domain and names the same report number, and shows you a link to open — so verifying takes one click. It can’t run the check for you, because the laboratory’s verification page doesn’t allow automated access. See what a report looks like, or read other things worth checking on a COA.
