Incretin & metabolic signalling
Metabolic Peptides in Canada
10 compounds in stock
The metabolic category is where incretin research sits: GLP-1, GIP and glucagon receptor agonists, plus the GHRH and monoamine compounds studied around body-composition endpoints. It is the deepest category in the catalogue, and the one where mechanism differences matter most when choosing a compound. Priced and shipped in CAD, for laboratory and research use only.

Single, dual and triple agonists
The incretin compounds separate cleanly by how many receptors they engage. Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GLP-1/GIP agonist. Retatrutide is a triple GLP-1/GIP/glucagon agonist and the newest of the three. GLP-1 receptor agonists compared covers the class; for head-to-head detail see retatrutide vs tirzepatide and tirzepatide vs semaglutide.
Beyond the incretins
Tesamorelin is a GHRH analogue studied specifically around visceral adipose tissue — a different axis entirely from the incretins. Tesofensine is a triple monoamine reuptake inhibitor, a small molecule rather than a peptide. AOD-9604 is a growth-hormone fragment studied around lipolysis without the full GH signalling profile.
Pens and formats
This category is the main reason the reloadable 3 mL pen format exists — retatrutide is stocked as a pen alongside 10 mg, 15 mg, 20 mg and 30 mg vials. Pens change the reconstitution arithmetic because the volume is fixed; the dosage calculator handles both formats.
Research context and comparisons
Because these compounds share mechanisms with named pharmaceuticals, the comparison content is where most questions land: retatrutide vs Ozempic, semaglutide vs tirzepatide, tirzepatide vs Mounjaro and generic semaglutide in Canada. The fat-loss foundations protocol covers research design. All of it is research framing — none of these compounds is supplied for human use.

Tesamorelin dosage — research dosing notes
A research reference on tesamorelin dosage: the fixed 2 mg daily dose used across the phase 3 trials, why the three approved formulations list different milligram figures, the sub-hour half-life, and the reconstitution math. A literature overview, not medical advice.
Tirzepatide dosage — research dosing notes
A literature overview of tirzepatide dosage: the 2.5 mg initiation step, four-week titration cadence, and 5/10/15 mg maintenance levels used in the trials, the ~5-day half-life behind once-weekly dosing, and reconstitution math for lyophilized vials. Research context only, not medical advice.
Semaglutide dosage — research dosing notes
A research-literature overview of semaglutide dosage: the STEP and SUSTAIN escalation schedules, the 7-day half-life behind the four-week cadence, and the reconstitution math from lyophilized vial to syringe units.
Metabolic peptides FAQ
- What are metabolic peptides?
- Metabolic peptides are sequences studied in research contexts around energy balance and body composition. The largest sub-class is the incretin receptor agonists — GLP-1, GIP and glucagon — which includes semaglutide, tirzepatide and retatrutide.
- What is the difference between semaglutide, tirzepatide and retatrutide?
- They differ by receptor coverage. Semaglutide is a single GLP-1 receptor agonist; tirzepatide is a dual GLP-1/GIP agonist; retatrutide is a triple GLP-1/GIP/glucagon agonist. Each additional receptor changes the research profile, which is why they are studied as distinct compounds rather than interchangeable ones.
- Can I buy GLP-1 research peptides in Canada?
- Yes. Canada Peptides stocks research-grade semaglutide, tirzepatide and retatrutide — the latter in 10 mg, 15 mg, 20 mg and 30 mg vials plus a reloadable pen — priced in CAD and shipped within Canada, for research use only.
- Are these the same as Ozempic, Wegovy or Mounjaro?
- No. Those are approved pharmaceutical products with their own manufacturing, labelling and regulatory status. The compounds here are research-grade materials supplied for laboratory use only and are not substitutes for any approved medicine.
- Which metabolic compounds are available as pens?
- Retatrutide is stocked in the reloadable 3 mL pen format alongside standard vials. See the pens page for the full list across all categories.
- Are these research use only?
- Yes. Everything in this category is supplied strictly for laboratory and research use. Nothing on this page is medical advice or a therapeutic claim.
