Peptide Certificates of Analysis

Peptide Certificates of Analysis (COA) for BlueNex Labs lots, including Janoshik identity and purity reports. This is batch documentation for Canadian laboratories — not a product listing. Research-use only.

This page is batch documentation, not a product listing and not a research guide. Each group links back to its catalog product URL when one exists. For how to read HPLC and mass-spectrometry reports, see How to read a peptide Certificate of Analysis.

Library last reviewed September 20, 2026. New lots are added when a report is published; dates on Janoshik are the record for when that test was run.

What peptide COA reports measure

Identity

Confirms the sample matches the named peptide sequence or compound, typically via mass spectrometry. If identity fails, the lot is not the material on the label.

Purity and mass

HPLC or related methods report how much of the detected peak is the named compound (purity) and, where listed, the measured mass in the vial. A purity figure for one batch does not document a later fill.

Endotoxin

Bacterial endotoxin testing is included on several popular lots and omitted on others. If a lot has no endotoxin link, that test is not in this library — do not infer a result.

Open the Janoshik URL on each lot and match the compound name, vial size, and cap or batch notes to the vial you received. Product pages deep-link to the matching section below; each section links back to the catalog page.

Identity or purity below 99%

If an independent lab shows identity failure or purity under 99% on an unopened vial from that batch, we replace it and refund the original payment. If a parcel does not arrive, contact the lab desk with the order number.
