TIRZEPATIDE 50MG

Description

Tirzepatide 50mg research peptide — Canada

Researched & reviewed by the SPO Quality Team · Last reviewed: 2 October 2026

Tirzepatide is a lipidated synthetic peptide that acts on both the GIP and GLP-1 receptors; a 2021 mouse study tied part of its metabolic effect to the GIP-receptor arm^[1]. This listing is one sealed vial containing 50 mg of lyophilized research-grade tirzepatide by label, the second-largest of our four strengths, supplied for laboratory research only.

Identity at a glance

Batch documentation: A batch-specific COA for this strength has not been posted yet — see the COA library (/coa/).

What researchers have looked at

• Mouse work (2021): in obese mice lacking the GLP-1 receptor, tirzepatide still improved insulin sensitivity through glucose uptake in white adipose tissue, pointing to the GIP receptor^[1].
• Pathway bias (2020): in HEK293 cells it leaned toward ERK1/2 phosphorylation over cAMP at both receptors when compared with the natural hormones^[2].
• Trial safety record (2023): a meta-analysis of ten randomised trials found gastrointestinal events, chiefly nausea and diarrhoea, were the most frequent adverse events^[3].
• Beyond diabetes (2024): two phase 3 trials enrolled adults with obstructive sleep apnea and obesity, with the apnea–hypopnea index as the primary endpoint^[4].

Regulatory status: as Mounjaro, tirzepatide is approved for type 2 diabetes in the USA, EU, Japan and elsewhere^[5]; Health Canada lists Mounjaro and Zepbound as prescription drugs. Trial results belong to Lilly’s licensed medicines and are not claims for this research material.

Storage and handling

• Long-term: −20 °C in the sealed vial (site guidance: up to 24 months as lyophilized powder). Short-term: cool, dry, away from light. Avoid thawing and refreezing.
• Bacteriostatic water is listed separately; methods are set by the researcher.

Other strengths: TIRZEPATIDE 10MG, TIRZEPATIDE 20MG and TIRZEPATIDE 60MG. Shipped by Canada Post from inside Canada (shipping policy); the rest of the catalogue is on our buy peptides online in Canada page.

Frequently asked questions

Where can I buy tirzepatide 50mg in Canada?

Here. The 50mg research vial is shipped by Canada Post from within Canada and does not pass through customs. It is sold for laboratory research only.

Has a COA been posted for the 50mg strength?

No batch-specific COA for the 50mg vial is in the COA library yet. We do not borrow the documentation of another strength or product; this answer will change when a report is posted.

How does the 50mg vial differ from the 60mg?

Only in the labelled quantity. Both hold the same lyophilized tirzepatide; the 50mg sits between the 20mg and 60mg listings for laboratories planning longer assay series.

Can this vial replace Mounjaro?

No. Mounjaro is Eli Lilly’s licensed prescription medicine. This vial is unlicensed research material, and no dosing or administration guidance is provided.
