Retatrutide Price in Australia

How Much Does a Vial of Retatrutide Cost in Australia?

A vial of retatrutide costs $139.99 for the smallest strength and $319.99 for the largest, from Australian Research Peptides, with every order dispatched from Sydney.

Every listed strength holds the same compound in the same form — lyophilised (freeze-dried) powder sealed in a glass vial. Only the quantity inside differs, which is why the price rises with the strength while the cost of each milligram falls.

Which Vial Size Is the Best Value per Milligram?

The 30 mg vial is the cheapest retatrutide per milligram at $10.67, against $14.00 for the 10 mg. Larger vials always cost less per milligram.

The saving is not spread evenly across the range, and that is the part worth knowing before choosing. 90% of the total fall in price per milligram arrives in the first step up, between the 10 mg vial and the 20 mg. Every step after that is comparatively small.

Whether the cheapest milligram is the right thing to optimise is a different question, and it is the subject of choosing a vial size — a per-milligram figure only counts across material that is actually used.

Are the Retatrutide Bundles Cheaper Than Separate Vials?

Every retatrutide bundle costs less than the same items bought separately, because each pairs vials with the bacteriostatic water and syringes an order usually needs anyway. The figures below are the bundle’s own, read from the same record its product page prints.

The other half of that answer matters just as much: a bundle is cheaper than its own contents, but it is not automatically the cheapest route to a given quantity of retatrutide. A single larger vial holds the same milligrams for less, without the water or the syringes. Which is better value depends on whether you need those items, not on the saving alone. The Retatrutide + Tesamorelin bundle is not quoted per milligram at all, because it holds two different peptides and a per-milligram figure across a mixed pair would compare nothing to anything.

How Much Is Delivery on a Retatrutide Order?

Standard tracked post is $12.99 and free over $199. Express Post is $16.99, free over $299 — a different threshold, and the one most often assumed to be the same. The table below runs every retatrutide route into the catalogue against both, so which rows post free is read rather than asserted.

Two things that table makes visible and a sentence does not. The two free-post thresholds are different figures, so an order can clear one and not the other — naming the service is the only way to say which postage is free. And free postage is assessed on the subtotal before any multi-vial discount is applied, so earning a discount can never push an order back under a threshold. Signature on delivery adds $2.95 to any row and is never pre-selected. Full detail is on shipping.

How Do You Pay for a Retatrutide Order?

Payment is by PayID or bank transfer, and those are the only two methods. No card, wallet or buy-now-pay-later option is offered. After an order is placed the payment details and a reference arrive by email, and the vials are held for 2 business days while the transfer clears.

The window counts business days rather than raw hours, which matters for an order placed on a Friday evening: a bank transfer that batches over the weekend is not penalised for arriving on Monday. Payment and dispatch questions are answered in more detail on the FAQ.

What Testing Comes With the Price?

Every retatrutide strength listed above is published against its own certificate of analysis from an independent laboratory. The certificates are published rather than described. Which strengths have one is visible on the certificates page, alongside the report for every other compound in the catalogue.

This is the part of a price that is easiest to leave out of a comparison and hardest to reinstate later. A cheaper milligram from a supplier who publishes nothing is not the same purchase, and the certificate is the only thing that turns a purity claim into something a buyer can check for themselves.

Is Retatrutide Approved in Australia?

Retatrutide is not approved by the Therapeutic Goods Administration and is not a registered medicine in Australia. It is not approved by any regulator anywhere, and it is supplied here strictly as a compound for in vitro laboratory research.

It remains investigational. The phase 3 TRIUMPH programme is four randomised, double-blind, placebo-controlled studies in more than 5,800 participants, and it has not reported. What the earlier published trials measured, and what is still unknown, is set out in the trial record, and how it differs from a single-receptor agonist in retatrutide versus semaglutide. What the supply terms mean in practice is covered under in vitro research requirements.

Every figure above is one Australian Research Peptides charges for stock it holds in Sydney, which is why the per-milligram column can be checked against a live listing rather than taken on trust.
