Research Articles and Guides
Literature overviews of the compounds we supply, written for researchers. Every article describes preclinical research only and is for informational purposes.
Welcome to the Canada Research Labs research blog, a hub for laboratory professionals, independent researchers, and students working with research peptides in Canada. Our articles cover peptide chemistry, storage and handling best practices, and comparisons between commonly studied compounds such as BPC-157, TB-500, CPB-1S, CPB-2T, and CPB-3R peptides.
All content here is published strictly for in-vitro research and educational use. None of our articles describe or endorse human or animal consumption. For questions about a specific compound, see our FAQ or review our Material Transfer Agreement.
Net Peptide Content vs Purity: Why a Vial Isn't 100% Peptide
The difference between peptide purity and net peptide content, what else is in a lyophilized powder, how each is measured, and why it matters for laboratory calculations.
HPLC and Mass Spectrometry Explained: What a Peptide Purity Number Means
How HPLC measures peptide purity and mass spectrometry confirms identity, what each result on a certificate of analysis tells you, and what neither one can tell you.
Research Peptide Glossary
Plain-language definitions of the terms used on research peptide labels, certificates of analysis and product pages, from acetate salt to WH2 motif.
Research Peptide Storage and Handling: Temperature, Light and Moisture
How to store lyophilized research peptides: temperature, light, moisture, freeze-thaw cycles, and which amino acids make some peptides less stable than others.
How to Choose a Research Peptide Supplier in Canada: 7 Checks
A practical checklist for evaluating Canadian research peptide suppliers: lot-matched COAs, third-party testing, purity data and domestic shipping.
