Buy Tirzepatide Peptide in Australia
Buy Tirzepatide in Australia from Macropus Peptides in two research-grade sizes, a 20mg and a 40mg vial, both priced and ready to order. Tirzepatide is a synthetic peptide of 39 amino acids that activates two incretin receptors, GIP and GLP-1, from a single chain, and a fatty acid side chain lets it bind albumin so it stays in circulation for days. That dual action makes it the reference compound for laboratories comparing single, dual and triple incretin agonists. Each vial holds lyophilised powder under a crimped seal, labelled with compound, strength, lot number and storage temperature, and a certificate of analysis is available for every lot. Order online, add bacteriostatic water for reconstitution, and the parcel ships from Australia to any address in the country. Sold to researchers aged 18 and over for in-vitro laboratory work only, never for human or veterinary use.

Buy Tirzepatide Australia: 20mg and 40mg Vials
Macropus Peptides stocks this dual incretin agonist in two priced sizes, 20mg and 40mg, both ready to order from Australian stock. It is the GIP and GLP-1 receptor agonist that metabolic laboratories keep as their dual-agonist reference. Both sizes are freeze-dried research material drawn from one controlled supply and released lot by lot, so switching between them alters the amount of peptide and the price per milligram, and nothing else.
Tirzepatide Australia: what the peptide is
Tirzepatide, coded LY3298176 during development, is a synthetic peptide of 39 amino acids built mostly on the sequence of GIP, the glucose-dependent insulinotropic polypeptide released by cells of the upper gut. Several positions were altered so that the same chain also switches on the GLP-1 receptor, which is why it is called a dual GIP and GLP-1 receptor agonist. A C20 fatty diacid, joined to the chain through a linker, lets the molecule ride on albumin in the bloodstream, and human pharmacokinetic studies recorded a half-life of about five days. It was the first dual incretin agonist of its type to complete a full clinical programme, and it is now the benchmark that newer multi-receptor peptides such as Retatrutide are measured against in the lab.
Tirzepatide peptide: how the dual agonist works in research
GIP and GLP-1 are the two incretin hormones, gut signals that amplify insulin secretion from pancreatic beta cells when glucose is raised. Each acts through its own receptor, and both receptors couple to the Gs protein and raise cyclic AMP inside the cell. The peptide is described as imbalanced because it activates the GIP receptor about as strongly as native GIP does, while its activity at the GLP-1 receptor is several times weaker than native GLP-1. At the GLP-1 receptor it is also biased: it favours cyclic AMP production over recruitment of beta-arrestin, the protein that pulls receptors into the cell, so less of the receptor is internalised. Laboratories use it to separate the contribution of each incretin receptor, to study signalling bias, and as the dual-agonist comparator in panels that also hold single GLP-1 agonists and a triple agonist.
Tirzepatide research: what the published studies show
Its discovery report, with the first human pharmacology, was published by Molecular Metabolism in 2018, while The Lancet ran a phase 2 study that year in people living with type 2 diabetes. The imbalanced and biased receptor profile was set out in JCI Insight in 2020, and cryo-electron microscopy structures of the peptide bound to both receptors followed in PNAS in 2022, showing how one chain fits two different binding pockets and where the lipid moiety sits. A phase 3 programme came next; its first monotherapy trial, published in The Lancet in 2021, measured glycated haemoglobin and fasting glucose against placebo. Designs, models and measurements for each paper are collected in our Tirzepatide research studies library.

Inside the glass is a pale, freeze-dried cake of dual agonist beneath an aluminium crimp. Printed details cover compound, milligram strength, lot code and storage temperature. Email that lot code and we return the matching certificate. Until the study starts, park the sealed dual agonist at -20 °C behind an opaque lid.
Tirzepatide price: what each vial costs per milligram
| Strength | Price | Price per mg |
|---|---|---|
| Tirzepatide 20mg | $249.99 | $12.50 per mg |
| Tirzepatide 40mg | $279.99 | $7.00 per mg |
Both vials carry a listed Australian dollar price and leave from stock. The 40mg vial costs only a little more than the 20mg vial yet holds twice the peptide, which brings its cost per milligram down to slightly more than half. The 20mg size is the smaller outlay for a first order or a short receptor series. Once a method is fixed and the work must stay on a single lot, the 40mg size is the economical buy, replacing two 20mg vials at a clearly lower total.
Tirzepatide 20mg: where to buy in Australia
Twenty milligrams is the size most incretin laboratories start with, and the one packed into our starter kit. It carries a method build and a full receptor assay series on one lot, which is useful because albumin binding of this lipidated chain in serum-containing media is best measured once and then kept constant. Typical stock volumes for this vial:
- 2 mL: 10 mg per mL
- 4 mL: 5 mg per mL
Tirzepatide 40mg: the lowest cost per milligram
Twice the peptide of the smaller size in one container, meant for long or multi-arm studies where every data point should trace to one batch. It is priced and shipped from stock exactly like the 20mg vial. Four millilitres of diluent brings the 40mg Tirzepatide vial to 10 mg per mL, identical to its smaller sibling made up with half that volume, so pipetting plans transfer directly. With 8 mL the stock sits at 5 mg per mL, handy when a plate series needs larger draw volumes.

Tirzepatide calculator: bac water for 20mg and 40mg vials
Our concentration calculator, attached to the product listing, converts whatever diluent volume you enter into a stock strength for the vial you bought, shown in both milligram and microgram terms. Quick reference points for the 20mg vial:
- 2 mL: 10 mg per mL
- 4 mL: 5 mg per mL
And for the 40mg vial:
- 2 mL: 20 mg per mL
- 4 mL: 10 mg per mL
With a molecular weight close to 4,813, a 10 mg per mL stock of the dual agonist is about 2.1 millimolar, a useful figure when receptor assays are planned in molar terms.
Let bacteriostatic water 10mL trickle down the glass rather than onto the cake, then swirl slowly until clear. Syringes and swabs sit under lab supplies.
Is Tirzepatide available in Australia
Registered medicines containing this compound hold ARTG entries and reach people only through medical channels. What we sell is different: unformulated research-grade peptide for in-vitro work, never to be given to a person or an animal. The compound itself is a scheduled substance under the Poisons Standard, so confirm how its current entry affects your organisation before placing an order.
Tirzepatide for sale Australia wide
Vials travel upright with the crimp shielded, bound for capital cities and country addresses alike. Laboratories building an incretin panel often add Retatrutide as the triple agonist and Cagrilintide for the amylin pathway, while the starter kit adds 3 mL of bacteriostatic water, ten syringes and swabs to a 20mg vial. The complete metabolic research range sits alongside.
