The short answer
37 laboratories are named on seller certificates we opened. 286 stores published at least one of those names. A name here tells you where a test came from. It is not a grade.
What this page does not do
No purity score, and no lab quality letter
The names below are facts about certificates we opened. They are not a ranking of laboratories against one another, and they carry no HPLC purity score. Seller certificate tier is still the ranking on every price page. The purity and dose gate is written and off. We do not invent pass or fail from missing certificates of analysis.
Deferred: HPLC scores, a lab quality letter, and turning the purity gate on. Those need quality data we are entitled to use. They are not shipped.
Read 2026-10-01. Counts are stores that named the laboratory. They are not certificate counts and not a ranking.
Sorted by how many sellers published the name. That counts what we could read. It is not a verdict on the laboratory. "Can you check it" means whether you can look a certificate up. The seller grade (lab-confirmed, A, B or C) still ranks the price cards.
You can look up a certificate by its search code, its accession number, or the exact company name printed on it. The lab says more than 40,000 certificates can be found this way. It only helps if you already have the code. It is not a list you can browse.
Every report has a task number, a unique key and a QR code. You can check all three on the lab's own verification page. There is also a public gallery at public.janoshik.com. A seller chooses whether a result shows up there.
Certificates go only to the customer. There is no public lookup or gallery.
A Verify page on their own site, where you enter a report ID. There is no list you can browse.
