As a GLP-1 research peptide and triple incretin receptor agonist, it simultaneously targets GLP-1, GIP, and glucagon receptors, making it a key research tool in metabolic biology. The TRIUMPH-1 Phase 3 trial topline results (May 2026) reported a mean body weight reduction of 28.3% at 80 weeks, with 45.3% of participants achieving ≥30% weight reduction at the highest dose. The 40mg pen format provides a higher-dose research option for studies requiring larger quantities.\u003c\/p\u003e\n\n\u003ch2\u003eAreas of Scientific Interest\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTriple incretin receptor agonism (GLP-1, GIP, glucagon)\u003c\/li\u003e\n\u003cli\u003eMetabolic rate and energy expenditure research\u003c\/li\u003e\n\u003cli\u003eAdipose tissue biology and lipid metabolism\u003c\/li\u003e\n\u003cli\u003eInsulin sensitivity and glucose homeostasis models\u003c\/li\u003e\n\u003cli\u003eComparative agonist pharmacology across incretin receptor subtypes\u003c\/li\u003e\n\u003cli\u003eBody weight regulation and energy balance research\u003c\/li\u003e\n\u003cli\u003eHigher-dose metabolic research protocols\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct: Retatrutide 40mg Peptide Pen\u003c\/li\u003e\n\u003cli\u003eQuantity: 40mg\u003c\/li\u003e\n\u003cli\u003eFormat: Pre-filled peptide pen\u003c\/li\u003e\n\u003cli\u003ePurity: ≥99%\u003c\/li\u003e\n\u003cli\u003eVerification: HPLC-tested, Certificate of Analysis available\u003c\/li\u003e\n\u003cli\u003eIntended use: Research purposes only\u003c\/li\u003e\n\u003cli\u003eStorage: Store at 2–8°C (refrigerated), away from light\u003c\/li\u003e\n\u003cli\u003eDispatched from the UK\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eResearch Applications\u003c\/h2\u003e\n\u003cp\u003eThe Retatrutide 40mg Peptide Pen is of significant interest to researchers requiring higher-dose GLP-1 triple agonist protocols.
