Independent third-party verification

Every batch. Every key. Every time.

Every compound we ship is independently HPLC-tested by Janoshik Analytical. Verify any test in 10 seconds — directly on Janoshik’s own site, with the unique key listed below.

How verification works

1

Find the key

Locate the unique Janoshik verification key for the batch you received — it’s printed on the COA in your shipment, and listed on every product page and on this page.

2

Enter it on Janoshik

Go to janoshik.com/verify and paste the key. Janoshik is a fully independent analytical lab — we don’t host or control their site.

3

Read the report

Janoshik will display the original HPLC test report with purity %, mass, test date, and lab signature. If the key is invalid, the test is fake — that’s the point.
