How to Verify a Janoshik Certificate in Five Checks
A Janoshik certificate is only as good as the record behind it. Entering the key takes a minute; knowing what to compare once the report loads is what actually catches a borrowed, edited or wrong-lot certificate.
1. Load the report from Janoshik, not from the seller
Every Janoshik certificate carries a task number and a unique key. Enter both at janoshik.com/verification, or open the verify.janoshik.com link printed on the report. The page that loads is served by Janoshik and shows the laboratory's own image of the report.
Compare that image with the copy the seller showed you, field by field. A certificate that does not resolve, or resolves to a different report, is the end of the check.
2. Read the sample line
The sample line is the name the client wrote on the order, printed as given. It should name the compound you are buying and, usually, the vial size that was tested.
A report for a 10 mg vial does not describe a 30 mg vial from another lot. Where several sizes are filled from one lot, the seller should say which lot each size comes from rather than leave you to assume.
3. Read the client line
The client is whoever paid for the test. Most research-peptide certificates name the manufacturer, because the manufacturer tests its own lots before selling them on.
That is useful evidence, but it is the manufacturer's evidence. A test ordered by the seller on its own retail stock, or by a buyer on a vial they received, says more about what is actually shipping.
4. Match the lot to your vial
The batch or lot code on the vial in your hand should match the batch on the certificate. A verified report for a different lot is a real report about different material.
If the vial carries no batch code at all, no certificate can be tied to it.
5. Check the dates and what was tested
Look at when the sample was received and analysed. A report older than the lot it is attached to cannot describe that lot.
Then read the requested tests. A standard report covers identity and purity, and often measured content. Endotoxin, sterility and heavy metals are separate analyses and appear only if they were ordered. Absence from the report means the test was not run, not that it passed.
Where to look further
Janoshik lists reports whose clients chose to make them public at public.janoshik.com. Independent projects such as Finnrick buy or receive vials from the public and publish their own results, which is the strongest evidence that does not depend on the seller.
Every Lyra Vital certificate is published with its task number and key, sorted by compound, with the client named on each row.

Common questions
How do I verify a Janoshik certificate?
Enter the certificate's task number and unique key at janoshik.com/verification, or open the verify.janoshik.com link printed on it. Janoshik's server returns its own image of the report. Then compare the sample line, client, batch and dates against the copy you were shown and the vial you hold.
What does the client line on a Janoshik report mean?
It names whoever ordered and paid for the test. On most research-peptide certificates that is the manufacturer. A report ordered by the seller on retail stock, or by a buyer, is stronger evidence about the material actually being sold.
Does a Janoshik certificate include endotoxin testing?
Only if it was ordered. The standard analysis covers identity, purity and often content. Endotoxin, sterility and heavy metals are separate tests that appear on the report only when requested.
Can a verified Janoshik report still be the wrong certificate?
Yes. A genuine report about a different lot or a different vial size verifies perfectly and still says nothing about your vial. Match the batch code on the vial to the batch on the report.
