How to Verify a Peptide in Canada
A vial is the end of a chain that runs from a synthesis lot to the note you write when the parcel arrives. Where each link sits, what proves it, how each one breaks in this market, and why a purity percentage cannot answer the quantity question.
The Complete Guide to Peptides in Canada
The checkable part of the Canadian peptide market: Health Canada's published position on research-use-only labelling, the difference between research grade and a certified reference standard, why a 99% purity result leaves the more expensive question unanswered, and a repeatable ten-point supplier evaluation.
The Complete Guide to Buying Peptides in Canada
The long version: what you are buying at a molecular level, how Canadian law treats it, the three grades of material and why the difference is expensive, what each analytical test can and cannot tell you, how to model landed cost, and what to record so a result stays traceable.
Understanding HPLC Purity Testing in Peptide Research
An in-depth look at how HPLC works, why it's the gold standard for peptide purity analysis, and how to interpret chromatographic data in COA documents.
How to Read a Certificate of Analysis (COA) for Peptides
A practical guide to interpreting COA documents for research peptides — understanding HPLC chromatograms, mass spectrometry data, and what each quality metric means for your research.
HPLC Testing for Peptides: Complete Guide to Purity Checks
HPLC testing serves as the main method for checking research peptide purity, with ≥99% purity as the standard for high-quality samples. This guide explains how HPLC works, what chromatograms reveal, and its role in verifying peptide quality. Researchers rely on it to ensure minimal impurities that could affect study results.
