Retatrutide in Canada — research-grade vials, lot-tested by HPLC + MS
Shipped Across Canada in 2-4 business days
Triple-agonist GLP-1/GIP/glucagon research peptide for pre-clinical metabolic labs. Six potency tiers (5, 10, 20, 30, 40, 60 mg per vial) so dose-response studies scale without reformulation. Every lot HPLC + MS assayed; batch-specific CoA on request.

What exactly is Retatrutide, and how does its triple-agonist mechanism differ?
Retatrutide is a synthetic peptide investigated in the pre-clinical incretin-axis literature as a triple agonist at the GLP-1, GIP, and glucagon receptors. Prescott Bio supplies it as a lyophilized peptide in six potency tiers so dose-response work can move without reformulation. Every lot is assayed by HPLC (purity) and mass spectrometry (identity).
Read more about the mechanism
Retatrutide sits alongside Tirzepatide (dual GLP-1 / GIP) and Semaglutide (GLP-1 mono-agonist) in the class of long-acting incretin analogs, distinguished by the addition of glucagon-receptor activity. The pre-clinical metabolic-axis literature discusses this third arm as the mechanistic distinction from earlier dual-agonist molecules.
Prescott Bio's Retatrutide inventory is presented in the potency tiers most often cited in dose-response studies. Certificates of analysis are batch-specific and available on request via the /coa lookup. All product is sold strictly for laboratory research use only.

How is Retatrutide different from Tirzepatide and Semaglutide?
All three ship from Canada, lot-tested. Click any column to see the PDP.
Retatrutide
GLP-1 / GIP / glucagon (triple agonist)
Newest of the three; adds glucagon-receptor activity to the incretin backbone.
From $70 / vial
Tirzepatide
GLP-1 / GIP (dual agonist)
Established dual-incretin analog. Widely cited in metabolic dose-response literature.
From $205 / vial
Tesamorelin
GHRH analog
GHRH-axis molecule — not an incretin, but often paired in metabolic study designs.
From $250 / vial
Why buy domestic vs cross-border import?
| Prescott Bio (Canadian domestic) | Cross-border import | |
|---|---|---|
| Ship time to Canadian lab | 2-4 business days from BC | 7-21 days plus CBSA hold risk |
| Currency and invoicing | CAD, GST/HST line-item | USD, FX friction, no CAD invoice |
| Customs and duty | None — dispatched inside Canada | CBSA declaration; duty and delay risk |
| CoA delivery | Batch-specific HPLC + MS per lot, PDF on request | Varies — often composite or template |
| Cold-chain risk | Domestic transit within stability window | Multi-week transit may exceed thermal wrap |
Questions Canadian labs ask before their first order
-
Is Retatrutide legal to buy in Canada for research?
Yes. Prescott Bio ships Retatrutide to verified research customers in Canada for laboratory research use only. It is not sold as a drug, food, cosmetic, or dietary supplement, and is not intended to diagnose, treat, cure, or prevent any disease. -
How is Retatrutide different from Tirzepatide?
Both are long-acting incretin analogs. Tirzepatide is a dual agonist at the GLP-1 and GIP receptors. Retatrutide adds a third activity — the glucagon receptor — making it a triple agonist. Pre-clinical literature discusses this third arm as the mechanistic distinction. -
How is Retatrutide reconstituted?
- Wipe the vial stopper with an alcohol swab.
- Draw the target volume of bacteriostatic water (typically 1-2 mL).
- Inject the diluent slowly against the vial wall — do not aim at the peptide cake.
- Swirl gently to dissolve. Do NOT shake.
- Store the reconstituted vial at 2-8°C. Use within 30 days.
-
How is Retatrutide stored?
- Refrigerate lyophilized vials at 2-8°C until first use.
- After reconstitution with bacteriostatic water, store at 2-8°C and use within 30 days.
- For storage beyond six months, freeze the sealed lyophilized vial at -20°C.
- Avoid repeated freeze-thaw cycles.
-
How fast does Prescott Bio ship?
Orders placed before 14:00 PT ship the same business day from our British Columbia facility. Canadian orders arrive 2-4 business days after dispatch. -
How recent is the current RT10 lot — will I get a CoA dated in the last 90 days?
Yes. Every RT10 shipment includes the lot-specific HPLC + MS CoA for the vial you receive; our current inventory rotates every 6-10 weeks, so CoA dates are typically within the last 60 days at shipment. Request the current lot's CoA before ordering by emailing our lab.
