Retatrutide (LY3437943) is a single 39 amino acid peptide acting as a triple receptor agonist at the GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon receptors. It is built on a GIP peptide backbone carrying non-coded residues at positions 2, 13 and 20, with a C20 fatty diacid conjugated through a gamma-Glu-AEEA linker to extend its half-life.

Yes. Vial AU supplies Retatrutide (5mg, 10mg, 15mg, 20mg, 30mg and 60mg) Australia-wide from Sydney, NSW as a research peptide for in-vitro laboratory research only. It is not a medicine or an approved therapeutic good, it is not for human or veterinary use, and every order requires a research purchasing declaration.
The highest published result is 99.27% purity (HPLC, lot APL-RETA5-2610-05, supplier lab, tested 23 Oct 2026). Purity is reported per lot: a size shows a purity figure only when a certificate exists for the exact lot in stock, otherwise it reads "Batch COA pending".
Yes. 6 independent third-party reports are published for Retatrutide, from Ozcanium Analytics and Janoshik. Supplier batch reports are labelled "Supplier lab", so independent and in-house results are never confused.
12 Retatrutide certificates are published in full, not sent on request. Each names the lot, the laboratory, the method and the test date. Match the lot code on your vial label to the certificate before relying on a result.
Orders paid by 14:00 AEST/AEDT on a business day are dispatched the same day from Sydney with Australia Post tracking, including to Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra and Darwin. Delivery usually takes 1–3 business days after dispatch; regional and remote addresses can take longer.
Keep the sealed vial dry, protected from light and frozen (around −20 °C) for long-term holding, and let it reach room temperature before opening to limit condensation. Solutions are far less stable than the lyophilised powder, so prepare them close to the experiment.
Supplied for laboratory use.Practice notes: storing lyophilised peptides, choosing a reconstitution solvent and peptide stability in solution. Use the concentration calculator for stock solutions in mg/mL and µM.
