Janoshik test number (the digits in a verify.janoshik.com link), report ID, or batch ID.
What is this?
Vendors and group buys hand out Certificate-of-Analysis report numbers as proof of purity. This tool checks that number against the lab reports we've archived so you can confirm what it actually tested at — before you trust it.
Where's my number?
On a Janoshik certificate it's the test ID — the same digits that appear at the start of a verify.janoshik.com/tests/<number> link. Paste just the digits.
