Peptide Research Library

Follow the six-guide reading path at the top of this page: what peptides are, what research use only means in Canada, how purity and identity are tested, how to read a certificate of analysis and how to store a sample. The research peptide glossary defines the terms used across the library.

No. The guides explain published research, laboratory methods and practical questions about buying reagents in Canada. Research peptides are sold for in-vitro laboratory research only. They are not for human or veterinary use, and no guide gives dosing, administration or treatment information.

Our Lab Testing page lists the current Janoshik Analytical report for each vial size of most products, with its batch code and a verification key. If your vial is from an earlier batch, or a product is not listed, the report is available on request. The guide to lot numbers and batch traceability explains how to match a vial to its report.

No. Many guides discuss compounds in our catalogue, but others explain hormones, receptors and signalling pathways, such as ghrelin, GPCRs, mTOR and NF-κB, that a researcher needs as background either way. The guides aim to separate what is established from what is preliminary or unproven.

Most guides end with a reference list of the peer-reviewed studies, regulator documents and standards they draw on, so you can check a claim at its source. If you spot an error, tell us through the contact page.
