Compound Overview

Retatrutide (LY3437943) is an investigational triple receptor agonist peptide targeting GIP, GLP-1 and glucagon receptors simultaneously. This 30 mg vial is the largest format we offer and carries our lowest per-milligram price by a wide margin. It is built for research programs running extended in-vitro studies, concentration-response series or multi-arm assay panels that would otherwise consume three separate 10 mg vials. The current lot is independently verified at 99.751% purity by HPLC, with 34.20 mg of assayed content against a 30 mg label.

Price: $180 CAD per 30 mg vial — $6.00 per mg, our best rate, against $9.00 per mg on the 10 mg vial and $7.00 per mg on the 20 mg vial. Three 10 mg vials cost $270, or $243 after the automatic 10% multi-vial discount — against $180 for a single 30 mg vial. That is a $63 saving, and the whole study stays on one verified lot. Shipping is free and tracked across Canada with no minimum order.

How much does Retatrutide 30mg cost in Canada?+

Retatrutide 30mg is $180 CAD per vial from ThePeptide.ca — $6.00 per milligram, the lowest per-mg price in our range. For comparison: Retatrutide 10mg is $90 CAD ($9.00/mg) and Retatrutide 20mg is $140 CAD ($7.00/mg). Shipping is free and tracked to every province and territory in Canada with no minimum order value, so the listed price is the delivered price before tax.

Which Retatrutide vial size is the best value?+

The 30 mg vial, clearly. Per milligram it is $6.00 ($180), against $7.00 on the 20 mg vial ($140) and $9.00 on the 10 mg vial ($90). Three 10 mg vials come to $270 — $243 after our automatic 10% multi-vial discount — while a single 30 mg vial is $180. That is a $63 saving on the same total quantity, and the entire study stays on one verified lot rather than three. Smaller vials only make sense if you specifically want sealed backups held in cold storage.

How does shipping work in Canada, and is it free?+

  • Processing: Dispatched within 48 hours (Mon-Fri)
