COA peptide certificates, Canada

Peptide Certificates of Analysis (COA) for BlueNex Labs lots, including Janoshik identity and purity reports. This page is the batch file index for Canadian laboratories. It is 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. Short definitions of HPLC, LC-MS, endotoxin (LAL), and Certificate of Analysis are in the RUO glossary. How this catalogue publishes those rows, and who checks them, is on documentation standards and the Alice Kay, Ph.D. record.

Library last reviewed September 26, 2026. New lots are added when a report is published; dates on Janoshik are the record for when that test was run.

How to verify a report ID

A row on this page is one analytical file for one lot. It can show a sample name, a labeled amount, a chromatography result (HPLC or UPLC area percent) for purity under the stated method, and a mass result used as an identity check against the named sequence. An endotoxin line appears only when that assay was run. The file does not assign a Drug Identification Number, and it does not authorize personal use.

To verify a report, open the Janoshik link on the row. The host is verify.janoshik.com or janoshik.com. The task identifier is the number in that URL, before the sample token. Match the sample name, the labeled amount, and the cap or batch note to the vial in hand. A photograph of a page is not the file. A report for another SKU or another milligram size does not document this vial.

Line-by-line reading of a PDF that you already matched is in how to read a row.

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.

How to read a row

The library is the index of published PDFs. The research notes below explain how to read a row and how to match it to a vial. They are not extra certificates. Checkout and Canada Post Xpresspost are a separate note: research peptides, Interac, and domestic fulfilment.

• What a peptide COA records — The Canada primer: one batch, one document, and what a missing line means.
• How to read HPLC purity — Area percent, wavelength, and why a chromatogram is not an identity test.
• How to read a mass result — Observed mass, adducts, and salt forms on a third-party PDF.
• How to read an endotoxin line — LAL and related results in endotoxin units, and what a missing link means.
• HPLC versus LC-MS — Batch-method overview: which trace answers purity, and which answers identity.
• Match the PDF to the vial — Cap colour, lot id, and the published library row for the vial in hand.

Worked examples use live catalog URLs only. BPC-157 10mg is the blue-cap row: see the BPC-157 10mg certificate. GHK-Cu 50mg is the white-cap row, with separate mass/purity and endotoxin links: see the GHK-Cu 50mg certificate. Retatrutide 10mg, Retatrutide 20mg, and Retatrutide 30mg are separate rows, each with its own mass and endotoxin link: 10mg blue (the Retatrutide 10mg certificate), 20mg purple (the Retatrutide 20mg certificate), and 30mg pink (the Retatrutide 30mg certificate). MOTS-c 10mg and MOTS-c 40mg are separate rows, as are NAD+ 500mg and NAD+ 1000mg, and tirzepatide 10mg and tirzepatide 30mg. SS-31 10mg has a published file. SS-31 50mg does not. Epithalon 10mg has a published file. Epithalon 50mg does not. Kisspeptin 10mg has one published file. Sermorelin has no row. TB-500 10mg has a purity report (the TB-500 10mg certificate) and no endotoxin link. The fragment-versus-protein note is What is TB-500?. The 5mg/5mg blend is a different lot. Hospira bacteriostatic water 30 mL has no published row. A peptide PDF does not document that bottle.

If a lot file falls short

If the lot's Certificate of Analysis, or an independent test of an unopened vial from that same lot, shows an identity mismatch or a purity figure below the figure printed on that lot's COA, we replace the vial and refund the original payment. That remedy is for the lot. It is not a sitewide purity or identity guarantee. If a parcel does not arrive, contact the lab desk with the order number.
