Retatrutide in Australia: A Research Guide (2026)

Where can you buy retatrutide in Australia? Bondi Labs supplies retatrutide (also written as “Reta”) from Australian stock, COA-verified per batch, with same-day dispatch on orders placed before 12pm AEST. This avoids the long overseas waits and customs delays of importing. Everything below is provided for research reference only.

What is retatrutide?

Retatrutide is a synthetic peptide studied as a triple receptor agonist, meaning in the research literature it is described as acting on three targets: the GLP-1 receptor, the GIP receptor and the glucagon receptor. It sits in the same broad family of incretin research compounds as tirzepatide (dual agonist) and semaglutide (single GLP-1 agonist), which is why it is often compared with them. It is supplied as a lyophilised (freeze-dried) powder in a sealed sterile vial.

Also searched as: Reta, Reta peptide, R3ta, or retatrutide 10mg.

Retatrutide vial sizes at Bondi Labs

Bondi Labs stocks retatrutide in a range of strengths so researchers can match the vial to their protocol: 5mg, 10mg, 20mg, 30mg and 60mg, plus a boxed 10mg option and a Retatrutide Premium Kit that bundles vials with bacteriostatic water, syringes and swabs. You can view current pricing and stock on the retatrutide product page.

Purity and COA verification

Every Bondi Labs batch is independently tested and a Certificate of Analysis (COA) is available. A COA reports the identity and purity of the compound (typically by HPLC and mass spectrometry) so you can confirm what is actually in the vial rather than relying on a label alone. Bondi retatrutide is supplied at ≥99% purity (HPLC). You can review batch documentation in the COA library.

Storage and handling

• Before reconstitution: the lyophilised powder is stable and should be kept cool and dark; refrigerate at 2–8°C for longer-term storage.
• After reconstitution: store the solution refrigerated at 2–8°C and avoid repeated freeze–thaw cycles, which can degrade peptides.
• Reconstitution is done with bacteriostatic water. Use the reconstitution calculator to work out volumes for your target concentration.

Retatrutide vs tirzepatide vs semaglutide

In the research literature these three differ mainly by how many receptors they target. Semaglutide is a single GLP-1 receptor agonist, tirzepatide is a dual GLP-1/GIP agonist, and retatrutide is described as a triple GLP-1/GIP/glucagon agonist. Bondi Labs stocks tirzepatide and cagrilintide alongside retatrutide for comparative research.
