Every figure above is transcribed from the laboratory’s own report by two independent reads that had to agree character for character. Janoshik publishes the report as an image, so these numbers exist as searchable text nowhere else, including at the lab. Where this page and the report ever disagree, the report is right.

That link leaves this site. It resolves on verify.janoshik.com, a domain Janoshik controls and we do not, which is the one part of a certificate a vendor cannot forge. If what you see there does not match what is on this page, trust the laboratory.

The report also prints a verification key, YX5UJHTL6KYI, which is the string the laboratory’s own URL is built from.

What this document proves, and what it does not

What this document proves

That Janoshik, a laboratory independent of this store, ran the test named above on the sample the laboratory received and tested.
That the analysis was carried out on 06 FEB 2026, the date the report itself prints.
That the values in the table are what that report records for that sample.
That the document is held by the laboratory, not only by us: the record resolves on verify.janoshik.com.

What it does not prove

Anything about a different lot. A certificate covers the material that was tested and no other production run, however similar the label looks.
Anything about doses other than 50mg. Each dose is tested separately, and other doses have their own certificates.
That a vial you are holding came from this lot. Match the lot on your vial against the certificate supplied with it before you rely on either.
Anything at all about safety, suitability, or effects. This is a purity and identity record for laboratory material, not a health claim.
