What each line on the report means
Janoshik's standard peptide report is a single page with the same fields every time, so once you've read one you can read most of them. The top half says whose test it is and what was sent in. The bottom half says what the lab found. The fields that matter most are the client, the batch, the results box and the unique key.
| Field | What it tells you |
|---|---|
| Task Number | The report's ID at Janoshik |
| Client | Who paid for the test |
| Sample | The name the client gave the vial |
| Manufacturer and Batch | Whatever the client wrote, sometimes "Unknown" |
| Analysis conducted | The date the lab ran the test |
| Results | Milligrams measured, and purity if ordered |
| Unique key | The code that proves the report is real |
In the results box, a line with the compound's name and a milligram figure is the amount Janoshik measured in that vial. A line marked Purity is a percentage, the share of the peptide material that's the compound named rather than leftovers from making it. A blend gets one line per compound. If the client sent several vials, you'll see several figures on one line, one per vial, which shows how evenly the batch was filled.
A missing line means nobody ordered that test, not that something failed. One report on a BPC-157 and thymosin beta-4 blend (the vial vendors sell as BPC-157 with TB-500) lists milligrams for three vials and no purity line at all, because purity wasn't part of what was bought. Endotoxin (bacterial debris), sterility and heavy metals work the same way, so if they aren't printed, they weren't tested.
How to tell the report is real, and that it's yours
At the foot of every report is the line "Verify this test at www.janoshik.com/verify/ with the following unique key," and a twelve-character code under it. Type that key into Janoshik's verify page, or scan the QR code above the results box, and the lab's own site shows you the original. If the copy on the vendor's page doesn't match what Janoshik shows, you have your answer. The verify page can also show photos of the vial as the lab received it, so you can see the cap color and the handwritten or printed label.
Then check three fields against your order. The client should be the shop you're buying from, or a name it can explain. The sample name and strength should match the product. And the batch should match the lot number on your vial. A batch field reading "Unknown" turns up on real reports, and it means the report describes one vial without tying it to a production run, so it says less about the vial headed to you.
Janoshik tests whatever arrives in the mail. The report is an accurate description of the vial the client chose to send, which is why a vendor who posts a report for each batch is telling you more than one who posts a single report for a product. Our guide on how to tell whether a certificate of analysis is real covers the same checks for any lab.
What the numbers change about your order
The milligram line is the one to read hardest, because it's the amount your dose math depends on. In the two reports we pulled for this page, both vials held more than their labels said. A figure well under the label means the vial is short, and the BPC-157 dosage page shows how the milligrams in a vial set the mixing math. Purity and milligrams are separate numbers, and a vial can be 99% pure and still light, which our piece on purity versus net peptide content walks through.
Janoshik doesn't claim an accreditation, and we found none when we checked, which we wrote up in what the labs behind your peptide COA are actually accredited to test. If you'd rather have your own vial tested, how to get your peptides tested covers the order and the cost, and the lab directory lists who takes samples. The vendor directory shows which shops post batch reports you can check, and the price app compares the real price per milligram for BPC-157 and every other compound we track. The BPC-157 page has the live prices too.
Everything these reports cover is sold for research, and a lab report describes one vial, not the next one you order.
Questions people ask
How do I verify a Janoshik test?
Go to janoshik.com/verify and enter the unique key printed at the bottom of the report, or scan the QR code on it. The lab's own site shows the original report, and a copy that matches it came from Janoshik.
What is the Janoshik unique key?
It's the twelve-character code printed at the foot of every Janoshik report, under the line telling you where to verify it. Entering it at janoshik.com/verify pulls up that one report on Janoshik's own site.
What does Janoshik test for?
For peptides, the standard test measures how many milligrams of the named compound are in the vial and how pure it is. Extra tests Janoshik sells, like endotoxin (bacterial debris), sterility and heavy metals, appear on a report only when someone paid for them.
Why does a Janoshik report show more milligrams than the label?
Vials are sometimes filled over the labeled amount, and both reports we pulled for this answer measured about a fifth above the label. A figure well below the label means the vial is short.
Is Janoshik an accredited lab?
Janoshik doesn't claim an accreditation, and when we searched the Czech national accreditation body's database for it, nothing came up. That doesn't make its numbers wrong, it means there's no outside body auditing them.
