If you are new to working with research peptides in Canada, this guide covers the practical foundations: what these compounds are, the form they arrive in, how purity is established, and how to prepare and store them correctly. Each section links to a detailed walkthrough so you can go deeper where needed.
What is a research peptide
Peptides are short chains of amino acids, the same building blocks that make up proteins. Research peptides are synthetic versions produced for laboratory study of biological pathways. They are supplied for in-vitro research use only and are not approved for human or animal use.
Why they arrive freeze-dried
Most research peptides ship as a lyophilized (freeze-dried) powder inside a sealed vial. Removing the water keeps the peptide stable during shipping and storage. Before use in the lab the powder is reconstituted with an appropriate diluent.

Purity and identity: the numbers that matter
Two measurements describe what is actually in a vial. High-performance liquid chromatography (HPLC) reports purity as a percentage, and mass spectrometry (MS) confirms the compound is the peptide it claims to be. A certificate of analysis presents both.
- How to read a certificate of analysis — interpret HPLC purity and MS identity.
- Peptide purity explained — what a 99 percent figure means and how it is measured.
Storing your materials
Lyophilized peptides are generally kept cold and away from light; once reconstituted, shelf life shortens and refrigeration matters. Correct storage protects the integrity of your research material.
