Every JP Peptides compound is sold for laboratory research use only.
The label makes a claim. The lab checks it.
Janoshik Analytical tests sealed vials from each lot and reports what it finds. We publish those numbers as the lab reports them.

Janoshik
Independent lab
Three tests, in plain words.
A certificate shows only the tests present in the lab’s report for that lot. Nothing is inferred or filled in.
- RP-HPLC · UV 214 nm
HPLC purity
Separates the sample into its parts and measures what share of the signal belongs to the target peptide. The release line is 98.0 %; every certificate prints the exact figure the lab reported.
- Quantitative HPLC
Net peptide content
Measures how many milligrams of peptide are actually in the vial and sets that against the label. A lot is released only when the measured mass is at least 90 % of the label claim.
- LAL · kinetic
Bacterial endotoxins
Screens for endotoxin from bacterial cell walls, reported in EU per vial against a research limit of 10 EU. It is a separate report, so it appears only on lots where the lab ran it.
Check your vial.
Three steps with the vial in your hand.
Step 1: Read the lot on the label
Every JP label prints a LOT code next to the expiry date. That code is the lot named on the certificate.
Step 2: Scan the QR code
Where the label carries a QR code, it opens the lab’s own report for that lot on the lab’s website. It shows what the lab found for the lot, not a check of one vial.
Step 3: Match it here
Type the lot code into the library search. The purity and net content on our certificate should read the same as the lab’s report.
Certificates, explained.
Which lot was tested, by which lab and on what date, and what the lab measured: HPLC purity, the milligrams of peptide actually in the vial and, where it was run, bacterial endotoxin. Each JP certificate covers exactly one lot.
Janoshik Analytical, an independent third-party laboratory. We send sealed vials from the lot; the lab runs the tests and issues the report. We transcribe its figures and do not edit them.
Read the LOT code printed on the label and type it into the search above. The lot on the certificate should be the same code. If the label has a QR code, scanning it opens the lab’s own report for that lot.
Endotoxin (LAL) testing is a separate report from purity and content. It appears only on lots where the lab ran it. We never fill in a result the lab did not report.
Archived means a newer lot of the same compound has been tested since; the certificate still describes the lot it names. In review means the lot fell short of our release line: purity below 98 % or measured content below 90 % of the label.
Yes. Send us the lot code on WhatsApp or by email and we will send the full report the lab issued for that batch.
Can’t find your lot?
Send us the lot code from your label. We will send that batch’s report, or tell you where its testing stands.
