Our mandate
Northbound Assay publishes educational content for Canadian buyers who want to verify a peptide batch before making any purchase decision. We do not sell products. We do not recommend suppliers by name. We do not advise on dosage, therapeutic use, or any application of research compounds in humans. Our singular editorial focus is: does the Certificate of Analysis in front of you meet the standards of an independently verifiable batch record?
Everything we publish is designed to help a buyer answer that question with more confidence than they had before reading it.
What counts as a real COA
The core criterion for every verification guide we publish is derived from what accredited analytical chemistry laboratories produce. A meaningful Certificate of Analysis must satisfy all of the following:
The COA must be issued by a laboratory that is independent of the seller. An in-house test report produced by the same entity selling the compound does not qualify. Independence is non-negotiable.
We look for accreditation to ISO/IEC 17025 or an equivalent national standard. ISO 17025 is the international benchmark for testing and calibration laboratories; accreditation by a national body (e.g., Standards Council of Canada recognised laboratories) demonstrates that the lab's methods, equipment, and procedures have been independently audited.
The report must state purity percentage by HPLC (high-performance liquid chromatography) for the specific lot or batch number referenced. A general product specification sheet without a lot number is not a COA — it is marketing copy.
Purity alone does not confirm you have the correct compound. We require that a COA also confirm molecular identity via LC-MS (liquid chromatography–mass spectrometry), matching the expected molecular weight of the target peptide sequence.
The lot number on the COA must match the lot number on the product label or packaging. A COA that cannot be traced to a specific batch you received is unverifiable.
What we do not verify
Northbound Assay does not inspect physical samples. We do not have a laboratory. We do not independently test compounds. Our editorial work teaches buyers how to read and assess a COA that a supplier provides — we do not certify any specific supplier's products as safe, pure, or fit for any purpose.
We also do not publish opinions on whether any compound is legal to import or use in Canada for any specific application. We summarise publicly available regulatory framework from Health Canada and CBSA for informational context only; we are not lawyers and this is not legal advice.
COA red flags — what signals rejection
Our guides consistently flag the following as ✗ rejected signals that a COA is insufficient:
- No lot number or batch number anywhere on the document.
- Purity stated as a range (e.g., "≥95%") without a specific measured value.
- Only HPLC data with no LC-MS identity confirmation.
- No reference to the issuing laboratory's name or accreditation number.
- PDF metadata or visual evidence suggesting the document was digitally edited.
- A "COA" that links to the seller's own website rather than to an external lab portal.
A COA passes our editorial threshold — ✓ accepted — only when it satisfies all five criteria in the section above and raises none of the red flags listed here.
How we research regulatory context
All regulatory framing on this Site (Health Canada classification, CBSA import enforcement, domestic vs. cross-border sourcing risk) is derived from:
- Publicly available Health Canada guidance documents and drug scheduling notices.
- CBSA import prohibition and tariff classification resources.
- Canadian legal databases (CanLII) for any relevant case law cited.
- Peer-reviewed literature where we discuss analytical chemistry methods (HPLC, LC-MS, Karl Fischer, endotoxin).
We do not rely on supplier marketing materials as a source. If a regulatory summary on this Site has a specific effective date or document reference, that reference is accurate as of the publication date stated on the article. Readers should independently verify current regulatory status.
Update cadence and corrections
Every editorial page on this Site carries an "Updated" date. We review pages for accuracy on a rolling basis; regulatory pages are prioritised for review whenever Health Canada or CBSA publishes relevant updates. If you identify a factual error, contact us at [email protected] with a subject line of "Correction request" and we will review within 14 days. Confirmed errors are corrected promptly and the page's update date is revised.
What we never publish
As a matter of firm editorial policy, the following content does not appear on this Site:
- Dosage recommendations or protocols for human use.
- Named supplier reviews or rankings.
- Before/after testimonials or anecdotal reports of compound effects.
- Claims that any compound treats, prevents, or cures a medical condition.
- Links to purchase compounds (outside the clearly labelled
/unlock/gate, which is markednoindex,nofollowand exists only to let readers who choose to proceed find a verified domestic supplier).
No anonymous authors or invented personas
Northbound Assay publishes under the brand name as an editorial collective, not under individual bylines or invented expert personas. We do not fabricate credentials, institutional affiliations, or named authors. Our authority claim rests on the quality and sourcing rigour of what we publish, not on a false person with a fabricated CV.
