Third-party tested, HPLC-verified, 99%+ purity. Every batch tested, Certificates of Analysis published where available.
Helix North supplies high-purity, third-party tested research peptides across Canada. Every production lot is independently verified by HPLC and mass spectrometry before it reaches the catalog, and Certificates of Analysis are published on the product page where we hold one. This is what "lab-tested peptides" means here — not a marketing claim, but a chromatogram, a lot number, and a lab signature you can check.

How we verify the identity and purity of every product we sell.
HPLC is the gold standard for peptide purity analysis. The technique separates a sample into its individual components by passing it through a column under high pressure. Each component elutes at a characteristic retention time, and UV detection at 220nm quantifies the relative abundance of the target peptide versus any impurities. Our acceptance criterion is 99%+ purity by peak area integration.
Mass spectrometry confirms the molecular identity of each peptide by measuring its exact molecular weight. We use electrospray ionization (ESI-MS) to generate a mass spectrum that must match the theoretical molecular weight within 0.1% tolerance. This ensures you receive the correct compound — not a misidentified or degraded product.
Together, HPLC and MS answer two critical questions: "Is this the right molecule?" and "How pure is it?" HPLC quantifies purity by detecting synthesis byproducts, truncated sequences, and degradation products. MS confirms molecular identity by verifying the exact mass of the peptide chain. Both results are documented on every Certificate of Analysis.
Six pillars that define our commitment to research-grade quality.
Every production lot is submitted to an independent laboratory for HPLC purity and mass-spectrometry identity testing.
Our peptides consistently test at 99%+ purity via HPLC analysis.
Certificates of Analysis are published on the product page where available, so you can read the results before ordering.
Production, purification, storage, and batch-release steps follow documented procedures.
Products are stored at controlled temperatures from production to your door.
Made and shipped in Canada, with independent lot testing kept separate from sales.
The records and checkpoints used before a production lot enters the catalog.
Our production partners use documented procedures for synthesis, purification, storage, and batch release. We do not present those procedures as a third-party GMP certification. The customer-facing evidence is the product-specific Certificate of Analysis where available, supported by the lot records retained for release decisions.
Raw-material checks, in-process controls, and finished-product testing are recorded against the production lot. Independent HPLC and mass-spectrometry results are reviewed before release, and a lot that does not meet its stated purity specification is not added to the catalog.
