Who Janoshik is
Janoshik s.r.o. is a testing laboratory registered in Prague, in the Czech Republic. It tests samples that customers send in. It says it does not sell products and does not recommend or comment on specific suppliers.
This page explains how its own checking system works. It is not an endorsement of the lab or of any report.
What you need
According to the lab's help centre, a report can only be checked if it shows both of these:
How to check it
Compare, do not just tick
The lab says a report is only genuine if it matches the version it holds. If anything has been changed, it does not count. So open the stored copy and compare it line by line with the one you were given: the sample name, the results, the date and the batch number.
If the task number or key is missing, the report cannot be checked. The lab suggests asking the seller for the full version.
What a match does not tell you
The header of a Janoshik report, including the manufacturer and batch number, is filled in by the customer who ordered the test. The lab also offers extra copies of a report with different header details. A verified report proves the lab issued it. It does not, on its own, prove which vial the sample came from.
