Documentation standards for batch Certificates of Analysis

What this page is for

The questions we get are concrete: who tested the lot, how to match the file to the vial, and what Canadian checkout actually does. This page answers those. Longer method notes stay in the research cluster. The live PDFs stay on the certificates library. Size, price, and stock stay on the product page.

Nothing here is a ranking of outside vendors, a city storefront, or a use protocol. Research use only. Not for human or veterinary use.

How a batch COA is published

BlueNex Labs lists batch Certificates of Analysis in the certificates library, grouped by catalogue material. A row is lot-specific. Where a catalogue page has more than one vial size, each size has its own report when that documentation exists. A COA for one batch or one milligram size does not document a different batch.

Many lots include a Janoshik identity and purity (mass) result. Several popular lots also include an endotoxin result. The date on the Janoshik file is the record of when that test was run. The library’s own review date is the date the public index was checked. Those dates are not interchangeable.

The testing laboratory and the shop are different parties. The laboratory named on the PDF produced the chromatogram. BlueNex Labs hosts the library from the Burnaby desk and ships inside Canada. The PDF has the analytical numbers. The library row says which cap that PDF is supposed to document. The vial is what arrived. If those disagree, email before you file the lot.

Alice checks how those rows are published. The record is Alice Kay, Ph.D., founder and biochemist. She does not sign the third-party chromatogram. If the PDF header and the library row disagree, use the contact page before an assay file is opened.

How a laboratory verifies a lot

Open the library, find the material and vial size, then follow the Janoshik link for that test. Confirm the compound name, the reported mass or purity, and any endotoxin line against the vial in hand. If a listing has more than one lot, match the cap colour and the batch notes on the library entry. A report for one cap does not document a different cap. The task identifier is the number in the Janoshik URL.

The short version of that match is the FAQ on verifying a Janoshik report.

Worked reading notes, with anchors, are how to read a peptide Certificate of Analysis, what a peptide COA records, how peptide purity is measured, endotoxin testing on a COA, and match the PDF to the vial.

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, the catalogue replaces the vial and refunds the original payment. That rule is also on the certificates page and the FAQ. It is a receiving remedy for the lot. It is not a sitewide purity or identity guarantee, and it is not a specification you can copy onto a later lot.

HPLC, mass, and endotoxin lines

Identity and purity answer different questions. HPLC or a related chromatographic method reports how much of the detected peak is the named compound. Mass spectrometry is what the library uses to confirm the sample matches the named sequence or compound. A purity figure without a matching identity result does not, by itself, name the molecule.

Short definitions live in the glossary: HPLC, area percent, LC-MS, endotoxin (LAL), and Certificate of Analysis. Bacterial endotoxin testing is present on some popular lots and absent on others. A missing endotoxin link means the test is not in this library. Do not infer a result. A neighbouring peptide's report does not fill that gap.

Research-use and Canada framing

Research use only means the lyophilized solid is supplied for laboratory and in-vitro work. The phrase on a label is not a Health Canada authorization. Authorized drugs in Canada carry an eight-digit Drug Identification Number. A Janoshik percentage does not add a DIN after the fact.

Read Are research peptides legal in Canada? before a purchasing office files a vial as a consumer good. The contract terms are the Terms. Advertising and intended use still matter under Canadian law. This page does not offer legal advice.

Interac and Xpresspost facts

Orders ship inside Canada only. Checkout uses a Canadian shipping address and Interac e-Transfer. Shipping is $25.00 flat rate; free on product subtotals of $299.00 or more. A tracking number is emailed when the label is created. Delivery estimates are not guarantees. Parcels are not redirected outside Canada.

The public contact address is 4309 Canada Way, Burnaby, BC V5G 1J3. Xpresspost labels use a Port Moody, BC PO Box as the sender. Put the Burnaby street address on a purchase order when the form asks for a supplier location. The PO Box is a mailing address only; the public business address is the Burnaby street address. The two strings are one domestic operation: the desk, and the carrier account.

The longer receiving note is research peptides, Interac, and Xpresspost. Short answers are on the FAQ.
