Peptides

Retatrutide Canada

Retatrutide supplied as a lyophilised reference material in 4 fills, released against a >99% specification and dispatched from British Columbia, Canada with the certificate for your lot in the box.

Every Retatrutide fill in the catalogue

The same material at each size, released against the same specification. The difference between the rows is the quantity in the vial and the price — each has its own catalogue number and its own batch certificate.

Retatrutide is also catalogued and searched as ly3437943 and ggg tri agonist. Those are identity synonyms for the same molecule, not related compounds.

Retatrutide specification and purity

Retatrutide is a fatty acid acylated single peptide combining GCGR, GIPR and GLP-1R activity on a heavily modified GIP backbone, with albumin binding giving it a half-life long enough for once-weekly administration in published protocols. This 5mg vial is the smallest retatrutide presentation offered and is intended for pilot experiments, receptor-binding assays and low-concentration arms of dose-response studies, where a larger vial would leave reconstituted material sitting past its usable window.

Retatrutide questions

Are research peptides like Retatrutide legal in Canada?

Retatrutide is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.

Is Retatrutide shipped from within Canada?

Yes. Every Retatrutide order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.

Does Retatrutide come with a certificate of analysis?

Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every Retatrutide lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.

How is Retatrutide supplied and stored?

As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.

Which fill of Retatrutide should I order?

Retatrutide is stocked in 4 fills — 5mg, 10mg, 20mg, 30mg. They are the same material released against the same >99% specification; the only difference is the quantity in the vial and the price. Each fill has its own page with its own catalogue number and its own certificates. Unopened vials can be returned within 14 days.
