Retatrutide (LY3437943) is an investigational triple receptor agonist peptide targeting GIP, GLP-1, and glucagon receptors simultaneously. This triple-agonist mechanism distinguishes it from dual-agonist compounds like tirzepatide and single-agonist compounds like semaglutide, making it one of the most closely watched metabolic research compounds in clinical development.
Each vial contains 10mg of lyophilized retatrutide at 99.68% verified purity, independently confirmed through third-party HPLC-UV and mass spectrometry testing. CAS Number: 2381089-83-2.

Research Context & Mechanism+
Retatrutide is commonly referenced in research involving incretin signaling, glucose-response mechanisms, appetite-related signaling models, and energy-balance pathways. It is currently in Phase 3 clinical evaluation through Eli Lilly's TRIUMPH program, with topline results from TRIUMPH-1 reported in May 2026 showing significant body weight reductions in participants with obesity.
The triple-agonist mechanism activates three distinct metabolic receptor pathways, which researchers study for potential complementary effects across energy expenditure, appetite regulation, and hepatic lipid metabolism.
Purity & Third-Party Testing+
Every batch of Retatrutide is independently tested by Testides (Toronto) using HPLC-UV for purity verification and mass spectrometry for molecular identity confirmation. Batch-specific Certificates of Analysis (COAs) are published on our Lab Results page.
