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.
GHRH Analogs Compared: Sermorelin, CJC-1295 and Tesamorelin
Sermorelin, CJC-1295 (with and without DAC) and Tesamorelin compared: sequence length, stabilizing modifications, enzymatic stability and how researchers choose between them.
Tesamorelin Research Overview: A Stabilized Full-Length GHRH Analog
A research overview of Tesamorelin: the discovery of GHRH, why native GHRH breaks down so quickly, how Tesamorelin's N-terminal modification works, and how it compares with shorter analogs.
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.
GLOW vs KLOW: Two Research Peptide Blends Compared
GLOW and KLOW blends compared: what is in each vial, how much of each component, the one peptide that separates them, and what researchers should know about blends.
Epitalon Research Overview: The Pineal-Derived Tetrapeptide
A research overview of Epitalon (Ala-Glu-Asp-Gly): its origin in pineal gland extracts, the telomerase studies it is known for, and the limits of a single-group literature.
Selank vs Semax: Two Russian Heptapeptides Compared
Selank and Semax compared: their parent peptides, sequences, the shared Pro-Gly-Pro design, the laboratory models each is studied in, and the limits of their literature.
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.
NAD+ Research Overview: Redox Chemistry, Sirtuins and PARPs
A research overview of NAD+: its discovery, its role in redox reactions, the enzymes that consume it, how cells make it, and practical notes for laboratory work.
BPC-157 vs TB-500: How the Two Research Peptides Differ
BPC-157 and TB-500 compared: structure, size, origin, research focus and literature, plus why they are often studied and sold together.
MOTS-c Research Overview: A Peptide Encoded in Mitochondrial DNA
A research overview of MOTS-c: how it was discovered, why a peptide encoded in mitochondrial DNA is unusual, and the laboratory models it has been studied in.
