Is tirzepatide available in Canada? What is sold here

Yes. Tirzepatide is available in Canada as a research chemical for laboratory use, and that is the only form pepuro sells it in. It ships within Canada as a freeze-dried powder, with a lab report for every batch. A research vial is not Mounjaro and is not a medicine.

What tirzepatide is, and how it relates to Mounjaro

Tirzepatide is a synthetic 39-amino-acid peptide that activates two receptors, GIP and GLP-1. Eli Lilly developed it. Mounjaro is Lilly's brand name for its licensed medicine containing tirzepatide.

What differs is the product. A research vial and a branded medicine can share a sequence and still be entirely different things in law and in manufacture. Mounjaro is a finished, regulated pharmaceutical. A research vial is lyophilized peptide sold for in-vitro lab work, with no drug approval behind it.

For how it sits beside the single-receptor and triple-receptor peptides, see semaglutide vs tirzepatide vs retatrutide.

Is research-grade tirzepatide legal to buy in Canada?

Research peptides, tirzepatide included, are bought and sold in Canada as research chemicals for laboratory use. Marketing, selling or using them as drugs for human consumption is not permitted. The line is intended use, not the molecule. Are research peptides legal in Canada? covers that distinction in full.

In practice this means a compliant supplier describes the molecule and proves what is in the vial, and nothing more. Any seller offering human-use guidance for tirzepatide is marketing it as a drug. This page is general information, not legal advice.

How long tirzepatide keeps at room temperature

The answer depends on whether the vial is still dry.

Freeze-drying removes the water, so the powder has very little to react with. That is why a tirzepatide vial ships without a cold pack and why a parcel that arrives warm is normal. Once water goes in, the solution is far less stable and the clock starts. The tirzepatide handling guide has the concentration table, and how to store research peptides explains the freezer and fridge rules.

Which tirzepatide source to trust

Every tirzepatide seller says their product is pure. The report is what separates them. Check these before ordering:

• A report for your batch. A PDF on a product page only shows that some batch was tested once, so the QR code on your vial should open the report for its own batch.
• A named, independent lab, because an unnamed lab might be the seller.
• An observed mass near 4813.45 g/mol. Retatrutide is 4731.32 and semaglutide is 4113.58, so the mass-spec line tells the three apart.
• HPLC purity at 99% or higher.
• Domestic shipping, which keeps the parcel clear of customs holds and import fees.
• Research-use terms stated plainly, with no human-use claims anywhere on the site.
