How to verify a Janoshik report

How do I verify a Janoshik report?

Janoshik Analytical is a testing laboratory that analyses peptides and other compounds for customers worldwide, and many peptide sellers share its reports. Its website gives every report a public verification route. The home page states that "every report in our database is verifiable via Verify tab in the menu or QR code on the report" (Janoshik home page).

1. Find the task number and the unique key printed on the report.
2. Open janoshik.com and choose Verify in the menu. The Verification page says: "Here you can verify the authenticity of any test conducted by our company" (Janoshik Verification page).
3. Type the task number into the Task number field and the key into the Unique key field, exactly as printed, then press Verify.
4. Alternatively, scan the QR code on the report with your phone camera. Check that it opens janoshik.com and not another domain.
5. Compare what Janoshik shows with the copy you were given, line by line.

Always go to janoshik.com yourself by typing the address. Do not rely on a verification link inside a seller's message or website, because you cannot tell where a forwarded link really goes.

Where are the task number and key on the report?

Both identifiers appear on the report itself. The task number is the reference for that analysis, and Janoshik's public listings show task numbers as a number after a hash sign. The key is a separate code that pairs with the task number. You need both: the Verification page asks for them as two required fields.

If you only have a cropped screenshot with no task number or key, you cannot verify it. Ask the seller for the full report. A seller who shares reports in good faith will normally have no problem sending the complete document.

What does a successful verification prove?

It proves that a report with that task number and key exists in Janoshik's records. When you compare the record with the copy you were sent, it also shows whether that copy has been changed. If a sample name, date, purity figure or amount differs between the two, trust the version on janoshik.com.

That is a strong check against edited or invented reports, and it is quick to do. It is worth doing for every report a seller uses to support a purchase.

What does verification not prove?

A genuine report describes the sample that was sent to the laboratory. Verification cannot tell you that your vial came from the same batch, or that the sample sent in was a typical vial rather than a chosen one. Those are questions about the seller, not about the report.

On that last point, Janoshik's public results page says plainly: "We do not endorse, sponsor, or have any affiliation with any of the companies, organizations, or products listed" (Janoshik public tests). A report shows what a sample contained. It is not an approval of the business that sent it.

How do I check the report matches my vial?

• Compound and label amount. A report for a 10 mg vial does not describe a 30 mg vial.
• Batch or lot code. If the report names a batch, it should match the code on your vial. If it names none, you cannot link the two.
• Date. A report from long before your purchase may describe stock that has since sold out.
• Which tests were run. Check whether the report includes identity, purity, amount and endotoxin, or only some of them.

For retatrutide this matters more than usual. Retatrutide sells for more than tirzepatide or semaglutide, so a swap is the main thing to rule out, and only an identity result does that. Janoshik's own catalogue lists a GLP-1 peptide blind test covering semaglutide, tirzepatide and retatrutide (Janoshik home page). If the report includes identity, check the compound it names is the one printed on the vial. For the full set of questions, use the COA checker, and read how to read a peptide COA for each result line.

What if the report does not verify?

First rule out simple errors. Retype both codes exactly as printed, watching for similar characters such as 0 and O, or 1 and l. Make sure you are not mixing the task number from one report with the key from another.

If it still fails, contact Janoshik through the contact form on its website, which offers a "Report Verification Request" subject (Janoshik Verification page). Until the issuing laboratory confirms the report, treat it as unverified, not as evidence.

What is the Janoshik public results list?

Separately from the Verification page, Janoshik runs a searchable list of public tests at public.janoshik.com, linked as Public results in its menu. Each entry shows a task number, the sample description, the test type and who submitted it. Reports appear there on request, and the contact form lists a "Public Report Request" subject for this. The list is a convenient lookup, but the task number and key check is the direct route for a report you have in hand.

How do Tested.ph records compare?

Tested.ph uses the same idea. Tested.ph is not a laboratory: analysis is done by a partner laboratory and signed by its registered chemist, as the Chemistry Profession Act requires for an official certification of chemical analysis in the Philippines (RA 10657, Section 40). The partner laboratory will be named before testing opens.

Each Tested.ph record has a task number and a key, written together as in 1042-K7QX9M, and anyone can check it at tested.ph/verify. The stored report also has a SHA-256 fingerprint, so a changed file no longer matches the record. To test a retatrutide vial of your own, see the retatrutide test page.
