Retatrutide, developed under the code LY3437943, is a synthetic 39-amino-acid peptide built on a glucose-dependent insulinotropic polypeptide (GIP) backbone and engineered as a single molecule that activates three receptors: GIP, GLP-1 and glucagon. Researchers search for this bundle as a retatrutide kit, reta starter kit or retatrutide bundle, and the peptide is often shortened to reta.\u003c\/p\u003e\n\u003cp\u003eRetatrutide is studied mainly for body-weight regulation in obesity models, glycaemic control in type 2 diabetes models and reduction of liver fat, with a Phase 3 clinical program under way. At the receptor level it is a triple agonist: GIP and GLP-1 receptor signalling is associated with glucose-dependent insulin release and reduced food intake, while glucagon receptor activation is linked to hepatic fat oxidation and energy expenditure, so the three pathways are investigated together.\u003c\/p\u003e\n\u003cp\u003eOmega Peptides Australia supplies the Retatrutide in this kit as a high-purity (≥99% HPLC), COA-verified lyophilised powder, dispatched same day from within Australia on orders placed before 12pm, with the batch Certificate of Analysis published in the \u003ca href=\"\/pages\/certifications-of-analysis\"\u003eCOA library\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eWhat is included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 × Retatrutide 10mg vial\u003c\/strong\u003e, lyophilised powder in a sealed sterile vial, ≥99% HPLC purity with a batch COA, $159.99 separately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 × 3mL bacteriostatic water\u003c\/strong\u003e, sterile water with 0.9% benzyl alcohol preservative for reconstitution and multi-draw stability, $14.99 separately as the 3mL \u003ca href=\"\/products\/bacteriostatic-water\"\u003eBacteriostatic Water\u003c\/a\u003e vial.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 × 1mL insulin syringes\u003c\/strong\u003e, sterile, individually sealed, fixed-needle U-100 syringes, $15.99 separately as the \u003ca href=\"\/products\/1ml-insulin-needles\"\u003e1mL Insulin Needles\u003c\/a\u003e 5 Pack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 × alcohol swabs\u003c\/strong\u003e, individually sealed, for wiping vial septa before each puncture.

Bacteriostatic water is the recommended diluent: it dissolves the peptide cleanly, adds no salts or buffers, and its 0.9% benzyl alcohol keeps the reconstituted vial bacteriostatic across repeated draws over 28 days. Because Retatrutide is studied at low concentrations, a single 10mg vial is reconstituted once and sampled many times.\u003c\/p\u003e\n\u003cp\u003eThe syringes and swabs close the loop. Fixed-needle 1mL syringes graduated in 0.01mL units measure the diluent going in and the aliquots coming out, while the swabs decontaminate the septa.
