A Canadian alternative to Janoshik

Janoshik is the lab most peptide certificates cite. If you are in Canada, the analysis is not the only thing you are choosing: the parcel, the border, the currency and the tax come with it.

Janoshik Analytical, based in Prague in the Czech Republic, is the name on more peptide certificates than any other testing service, and it accepts samples mailed from abroad. Many Canadian buyers first learn about independent testing through its reports.

This guide does not compare anyone’s results or accuracy. It compares the parts of the decision that change when the sample starts in Canada.

What to keep the same, whichever lab you use

Ask for identity, not only purity. A purity figure on its own does not confirm what the compound is; that needs the sample compared against reference data for the compound named on the label. Purity versus identity.
Ask for measured content. Purity does not tell you how many milligrams are in the vial, and it is a separate measurement wherever you send the sample. Try the purity calculator.
Verify the certificate at the source. Look the report up by number on the issuing lab’s own site rather than trusting a PDF or screenshot. How verification works.
Remember what one vial tells you. A result describes the sample tested, not the whole batch.

Canada Peptide Testing accepts mail-in samples from every province and territory and reports HPLC-DAD area purity and identity against reference spectra on a verifiable certificate that carries the chromatogram. Peptide analysis is $299 CAD per sample, and quantitative content can be added on request.

Where is Janoshik located?

Do I need a customs declaration to send a peptide sample overseas?

International parcels leaving Canada carry a customs declaration describing the contents, and the parcel is subject to inspection in transit. A domestic shipment to a Canadian laboratory stays inside Canada and needs no international declaration.
