Semaglutide
Research use only.
Semaglutide is the GLP-1 research peptide that put this whole category on the map. It is a lab-made copy of a natural gut hormone (GLP-1) that helps the body feel full and manage blood sugar. It works on a single pathway, which makes it the simplest of the popular metabolic peptides.
What it is studied for
- Appetite: how it reduces hunger and food intake.
- Weight management: the focus of its best-known trials.
- Blood sugar: how it helps the body regulate glucose.
How it works (in plain terms)
GLP-1 is a hormone your gut naturally releases after eating. It tells the brain you are full and helps steady blood sugar. Semaglutide mimics that signal but lasts much longer, which is why research versions are studied as a once-weekly injection.
How it compares to tirzepatide and retatrutide
Think of it as levers: semaglutide pulls one (GLP-1), tirzepatide pulls two (GLP-1 and GIP), and retatrutide pulls three (adding glucagon). Semaglutide is the most-studied compound and the starting point for the whole class.
Storing and mixing it (for lab use)
Semaglutide 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
Is this the same as a prescription medicine? No. We supply semaglutide strictly as a research compound — not for human or animal use, and not as a substitute for any prescribed medication.
Why is it called a "GLP-1 agonist"? Because it switches on the GLP-1 receptor, the same one your body's natural fullness hormone uses.
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 Semaglutide
Semaglutide is a long-acting GLP-1 receptor agonist. A C-18 fatty-diacid side chain lets it bind albumin, dramatically extending its half-life compared with native GLP-1 — which is why it became the benchmark compound in GLP-1 and incretin research.
Key research areas
- GLP-1 receptor agonism — Selective activation of the GLP-1 receptor.
- Half-life engineering — Albumin binding via the fatty-acid side chain.
- Incretin research — Glucose-dependent insulin-secretion models.
- Benchmark comparisons — The reference point for tirzepatide and retatrutide research.

Frequently asked questions
Why is semaglutide long-acting?
A C-18 fatty-diacid side chain binds albumin in circulation, protecting it from rapid breakdown and clearance.
How does it compare with tirzepatide and retatrutide?
Semaglutide is a single (GLP-1) agonist; tirzepatide is dual (GIP + GLP-1); retatrutide is triple (GIP + GLP-1 + glucagon).
Does every batch include a COA?
Yes. Every batch is HPLC-tested with its own certificate of analysis.
Is semaglutide for human use?
No. This product is sold strictly for laboratory research use only.
