Buying Retatrutide in Canada (2026): Why It’s Called GLP-3/RT, Price, and How to Order
Searching “buy retatrutide Canada” and finding nothing called retatrutide? Here’s why it’s sold as GLP-3/RT, what it costs, how to avoid fakes and customs, and how ordering works, explained simply.
- Retatrutide is sold in Canada as a research compound, often under a code name; Popular Peptides lists it as GLP-3/RT (retatrutide) 10mg at $69.99 CAD.
- GLP-3/RT is the same molecule as retatrutide (LY3437943), a triple agonist of the GLP-1, GIP and glucagon receptors developed by Eli Lilly.
- As of 2026, retatrutide is investigational and not an approved medicine in Canada.
- Buying from a Canadian supplier avoids customs holds, GST/brokerage surprises and USD pricing; imported retatrutide parcels can be held by the CBSA.
- Because retatrutide is widely faked, check for a batch-specific lab report with a matching lot number and an LC-MS identity test; Popular Peptides batches can be looked up at /verify.
The quick version
If you searched “buy retatrutide Canada,” you’ve probably noticed something odd: a lot of Canadian shops don’t use the word “retatrutide” on their product pages. Neither do we. On our site it’s listed as GLP-3/RT. Same research compound, different label, and we’ll explain why in a second.
Here’s the one-breath version: GLP-3/RT (retatrutide) 10mg is $69.99 CAD, it ships from Vancouver by Canada Post Xpresspost so it never touches customs, and you can look up the lab report for your exact batch before you ever open the box.
Why is retatrutide called “GLP-3/RT”?
Short answer: payment processors. Card companies and the banks behind them get nervous about certain compound names, so many Canadian suppliers list retatrutide under a code. “GLP-3” is shorthand people use because retatrutide works on three receptors (more on that below), and “RT” is simply retatrutide’s initials.
It’s the same molecule, sometimes also referred to by its development code LY3437943. You’ll also see people call it “reta,” “retta” or “reta peptides” online. We wrote a whole explainer on what those nicknames mean if you’re curious.
What is retatrutide, in plain words?
Retatrutide is a lab-made peptide developed by Eli Lilly. It’s getting a lot of attention because it’s what scientists call a “triple agonist.” Picture three locks on a door. Older compounds fit one lock. Tirzepatide fits two. Retatrutide fits all three: the GLP-1, GIP and glucagon receptors.
As of 2026 it’s still an investigational compound, which means it’s being studied in clinical trials and isn’t an approved medicine in Canada. If you want the numbers from those trials, our retatrutide phase 3 trial data breakdown and deep dive have them.
Where to buy retatrutide in Canada
This is where most people get burned. The search results are full of US and overseas shops. Some are fine. But retatrutide is exactly the kind of parcel that gets pulled aside at the border, and when that happens most sellers won’t replace it. You’re out the money and the time.
| Buying from a Canadian shop | Buying from the US or overseas | |
|---|---|---|
| Customs | None | Can be held or refused by the CBSA |
| Surprise fees | None | Possible GST/HST and brokerage |
| Price shown in | CAD | Usually USD |
| Delivery | 1–4 business days | 1–6 weeks, longer if held |
| Lost parcel? | Email one Canadian company | Chase a foreign seller |

How much does retatrutide cost in Canada?
Ours is $69.99 CAD for 10mg. When you compare prices across shops, keep it apples to apples:
- —Same milligrams. A cheap 5mg vial isn’t cheaper than a 10mg one.
- —Same currency. $55 USD is roughly $75 CAD by the time your card is done with it.
- —Same proof. A price with no lab report isn’t a price, it’s a gamble.
- —Shipping included? We’re free over $300 CAD and a flat $20 below that.
How to spot fake retatrutide
Because it’s in demand, retatrutide is one of the most faked compounds out there. Protect yourself:
- —Ask for the lab report for the batch you’ll get, not a generic one.
- —Make sure the lot number on the report matches the lot number on the vial.
- —Check that the report names a real lab and includes an identity test (LC-MS), not just purity.
- —Be wary of prices way below everyone else.
For our GLP-3/RT, the current batch report is public: type the lot number from your vial into our batch checker and it comes right up. More on this in how to verify reta peptides in Canada and our COA guide.
How to order, step by step
- —Go to GLP-3/RT 10mg and choose your quantity. Multiples get a bundle discount.
- —Add bacteriostatic water ($9.99) if you need it, since it ships as a dry powder.
- —Pay by card, Apple Pay, Google Pay or Interac e-Transfer, all in CAD.
- —It ships within 1–2 business days, with tracking by email.
- —When it lands, check your batch on /verify.

Retatrutide vs tirzepatide vs semaglutide
These three get compared constantly, and it’s confusing. We wrote a plain-English side-by-side: semaglutide vs tirzepatide vs retatrutide. The short version: one lock, two locks, three locks. If you’re also looking at tirzepatide, see our tirzepatide buying guide or the GLP-2/Tirz product page.
