Janoshik Analytics Review

Janoshik is the de facto reference lab for the peptide and research-chemical space — the COA vendors cite most often and the one buyers check first. It's a straightforward fee-for-service operation open to anyone: individuals and vendors submit the same way, pay online, ship a sample, and get results in about four days on average (its guarantee caps that at 21 days). The full peptide menu is published ($215–$800 per test) and it explicitly offers blind testing — masking the compound's identity from the analyst — plus a public verifier where anyone can look up a report by test ID.

What makes it trustworthy isn't a plaque on the wall — it isn't ISO/IEC 17025 accredited, and it says plainly that a Janoshik COA is a community-grade check, not a regulatory document — it's the track record. Independent audits of its public database found failed and off-label results published right alongside passes, and forum users who've deliberately mislabeled test samples report Janoshik catches the swap every time. It has also, on at least one documented occasion, publicly called out a vendor's doctored COA.

The caveats are real: its public database is opt-in, so it reflects only the results vendors and buyers choose to publish, not everything the lab tests. A February 2026 data breach exposed some customer shipping information. And with no accreditation, its numbers should be read as directional, not certified. None of that has dented its reputation as the closest thing this market has to a shared, trusted reference point.
