Research standards, transparently documented.
A Canadian approach to independent laboratory verification.
Every research material sold under the Canada Peptide Supply banner is analyzed by an accredited independent laboratory before it reaches our catalog. This is not a marketing claim — it is a documented process, and the documentation is published on the product page for every batch.
Why independent testing matters
The gap between what a supplier says about a research material and what an independent laboratory measures is where research reproducibility lives or dies. A batch labeled ≥99% pure that is actually 92% pure will produce inconsistent results across a study — and the researcher, not the supplier, absorbs the consequence.
Independent third-party testing is the only way to close that gap. It moves the question from “does the supplier claim this is pure?” to “does an accredited lab, with no financial interest in the outcome, confirm it?”
Our documented process
Every production lot follows the same protocol:
- Synthesis at our manufacturing partner in Canada
- Independent sampling — a portion of each lot is drawn and shipped to Janoshik Analytical, an accredited third-party lab
- HPLC analysis — high-performance liquid chromatography measures the percentage of the target compound relative to impurities
- Mass spectrometry — confirms the molecular identity of the compound
- Endotoxin (LAL) testing reported on selected lots — an additional quality signal uncommon at our tier
- Batch approval — lots that fall below our ≥99% purity threshold are rejected, not sold at a discount
- Publication — the Certificate of Analysis for the approved batch is published on the product page before we ship inventory from that batch
Verifiable, not just published
The strongest form of transparency is verifiability. Every Certificate of Analysis we publish carries a lot number that matches the label on the container you receive. You can enter that lot number at public.janoshik.com and see the same report we published.
Three checks — container label, published Certificate of Analysis, independent lab portal. Anyone can perform them. If any of the three don’t match, we want to hear about it directly.
What we test for
| Analysis | What it measures | Why it matters |
|---|---|---|
| HPLC purity | Percentage of the target compound relative to impurities | Determines the reliability of dose-response measurements |
| Mass spectrometry (identity) | Molecular weight and structural signature | Confirms you received the material labeled on the container |
| Endotoxin (select lots) | Bacterial contamination markers | Relevant for higher-standard research protocols |
| Batch traceability | Unique lot number tying material to report | Enables independent verification |
Compliance framing
All materials on canadapeptidesupply.ca are labeled and sold for research purposes only. Not for human consumption. We do not offer clinical guidance, dosing recommendations, or medical advice, and we do not market to consumers. Our documentation and framing are consistent with Health Canada’s April 2026 advisory on the labeling of research compounds.
