Research-grade retatrutide pricing in Australia

Polaris Research supplies retatrutide as a research-grade lyophilised powder in two vial sizes: 10mg and 20mg. The 10mg vial is the standard entry format and divides cleanly into the reference aliquots most researchers use. The 20mg vial is the larger format, chosen by researchers running longer metabolic blocks who want to work from a single vial rather than repeated smaller ones.

On a per-milligram basis, the 20mg vial is the better-value format for extended research cadences. Every order includes free Australia Post Express Delivery Australia-wide and an independently verified batch certificate (≥98% purity). There are no hidden shipping fees or subscription requirements, the price you see is the price you pay.

What is included with every order

Every retatrutide order from Polaris Research ships with the lyophilised peptide vial, tracked Express Delivery, and an independently verified batch certificate that you can look up on our batch verification page using the batch number on the label.

Orders dispatch within 2 business days of confirmed payment, most within 24 hours (weekends excluded). Every order includes free Australia Post Express Delivery Australia-wide with tracking. A 24-hour payment reservation holds your stock from the moment you order, so the vial is yours while payment clears.

How research-grade pricing compares to a future pharmacy supply

Retatrutide is still an investigational compound. Lilly states it remains in Phase 3 clinical trials, with public launch dependent on trial completion and regulatory approval. It is not available at Australian pharmacies like Chemist Warehouse, and it is not available as a compounded prescription product through Australian compounding pharmacies at this time.

When retatrutide is eventually approved and released commercially, the pharmacy price is likely to be significantly higher per dose than the research-grade price per vial, because pharmacy supply includes the cost of drug development, regulatory approval, clinical trials, distribution through pharmacies, and prescription oversight. Research-grade supply is priced for laboratory use, not for pharmacy dispensing.

For researchers searching terms like 'retatrutide cost australia' or 'retatrutide price per month', the practical distinction is: you can buy research-grade retatrutide in Australia now at the prices on this page; approved pharmacy supply does not exist yet and its pricing is speculative.

Other compounds in the metabolic family

If you are comparing retatrutide to other metabolic peptides, we also carry tirzepatide-equivalent compounds in the same family. For a head-to-head comparison of the receptor targets, see our Retatrutide vs Tirzepatide library guide. The key distinction is receptor reach: retatrutide targets GLP-1, GIP, and glucagon (triple), while tirzepatide targets GLP-1 and GIP (dual).

Every metabolic peptide in our range ships with Free Express Delivery and an independently verified batch certificate. The cost is per vial, not per subscription cycle. If it is the size of the single up-front figure rather than the compound that gives you pause, the total can be paid in four instalments at checkout for the same price.
