Is Janoshik legit?
The short answer
Janoshik is a real, long-established analytical laboratory in the Czech Republic and the most widely used third-party peptide tester as of August 2026, with reports that verify by task number and unique key. The recurring criticism is not of its measurements but of its publication model: clients decide whether results become public, so the visible dataset skews positive.
In detail
Separating the two claims is important. Whether an instrument produced a correct number and whether a public results listing is representative are different questions, and only the second is contested in most discussions.
Its published figures as of August 2026: $215 for a standard single-peptide test, $360 for the GLP-1 blind panel, average turnaround around 96 hours with a 21-day guaranteed maximum, and add-ons including raw data at $25 and a second report at $50.
Everything above comes from public sources on the dates shown. We are a laboratory that will compete with them, which is why we cite rather than characterise.
