Open the report link printed on our certificate page — it lands on verify.janoshik.com, Janoshik Analytical's own public verification database, and no account or payment is needed. Match the test number and every figure with what our page shows; if they match, you are reading the same test.
Step by step, on a real report
The worked example is our GHK-Cu certificate: Janoshik test #92374, three vials sampled as "A, B, C".
- Open the lab's link, not a file. On our certificate page the "Full report" button points to
https://verify.janoshik.com/tests/92374-A_B_C_VDX9ZQ6ET751. A link is checkable; a PDF screenshot is not. - Check the domain. The page must be on
verify.janoshik.comorjanoshik.com— Janoshik's own sites. Not a copy hosted by the seller. - Match the test number. Janoshik prints the test number on its page. It must equal the report ID on our certificate: #92374.
- Compare the figures, vial by vial. Our card and Janoshik's page must both show purity per vial — 99.777%, 99.835%, 99.798% — and measured content per vial — 56.09 mg, 57.17 mg, 56.31 mg. Every vial the lab tested is listed on both.
- Check the sample description. Janoshik lists the sample as received ("A, B, C" for this test) and the compound each result names (GHK-Cu). The compound tested must be the compound you are buying.
- Nothing to log into. Janoshik's verification database is public. If a link is broken or a figure differs, contact us — we publish exactly what the lab publishes, and a mismatch means our page gets fixed.
What Janoshik reports cover
Janoshik Analytical reports HPLC purity and measured quantity per vial. Their certificates do not include an identity result or a mass-spectrometry method, and the reports we publish carry no lot number — the report ID and product are the reference. Where a lab tested several vials, every vial's value is published, not just the best one.
Questions buyers ask
Do I need an account to see the report?
No. Janoshik's verification database is public — the direct link is enough.
The report ID on our page is #92374 — where does that number come from?
From Janoshik. It is the test number in their database and in their own paperwork; our certificate repeats it so you can match the two.
What if the figures on our page differ from Janoshik's?
Our pages are copied from the lab's report, so a difference means one of the two is out of date — contact us and check the lab's page, which is the authoritative record.
How is this different from a supplier's own PDF?
A seller-hosted PDF can be edited or reused. A page on the testing lab's own domain, rendered from their database, cannot be edited by the seller.
