Tirzepatide
Research use only.
Tirzepatide is a research peptide that sits right in the middle of the popular metabolic compounds. It is a dual agonist — it works on two of the body's appetite and blood-sugar hormones at once (GLP-1 and GIP), one more than semaglutide and one fewer than retatrutide.
What it is studied for
- Appetite: how working on two pathways affects hunger.
- Weight management: the focus of its largest trials.
- Blood sugar: how it helps the body regulate glucose.
How it works (in plain terms)
GLP-1 and GIP are two natural gut hormones that both play a role in fullness and blood sugar. Tirzepatide copies both signals at the same time. The idea researchers study is that hitting two pathways together may do more than hitting just one.
How it compares to semaglutide and retatrutide
Picture it as levers: semaglutide pulls one (GLP-1), tirzepatide pulls two (GLP-1 and GIP), and retatrutide pulls three (adding glucagon). Tirzepatide is the well-studied "dual" step in that ladder.
Storing and mixing it (for lab use)
Tirzepatide ships as a freeze-dried powder. Sealed, cold and out of the light, it stays stable for a long time. For research it is mixed (reconstituted) with bacteriostatic water, then kept refrigerated. Our on-site peptide calculator can help with mixing amounts.
What you get from us
Every batch is HPLC-tested with its own Certificate of Analysis (COA), so you can confirm identity and purity first. We ship across Canada, usually within 1–3 business days by Xpresspost.
Common questions
What does "dual agonist" mean? It means the molecule switches on two hormone receptors (GLP-1 and GIP) at once, instead of just one.
Is it an approved medicine? No. We supply tirzepatide strictly as a research compound — not for human or animal use, and not a substitute for any prescribed medication.
Do you include a COA? Yes — every batch has its own Certificate of Analysis you can view before buying.
Do you ship to me? We ship within Canada only.

About Tirzepatide
Tirzepatide is a dual GIP and GLP-1 receptor agonist — a single peptide that activates both incretin receptors. It is a key reference compound in incretin research, sitting between single-agonist semaglutide and triple-agonist retatrutide.
Key research areas
- Dual incretin agonism — Combined GIP and GLP-1 receptor signalling.
- Insulin-secretion research — Glucose-dependent insulin release in cell models.
- Metabolic research — Comparative studies against GLP-1-only agonists.
- Receptor pharmacology — Biased agonism at the GLP-1 receptor.

Frequently asked questions
How is tirzepatide different from semaglutide?
Semaglutide activates only the GLP-1 receptor; tirzepatide activates both GIP and GLP-1 receptors.
What sizes are available?
20mg and 30mg lyophilized vials, each with a per-batch certificate of analysis.
How should tirzepatide be stored?
Keep lyophilized vials frozen and protected from light; after reconstitution keep refrigerated at 2–8 °C.
Is tirzepatide for human use?
No. It is sold strictly for laboratory research use only.
