What Is Retatrutide (LY3437943)?
Retatrutide (development code LY3437943) is a 39-amino acid synthetic peptide developed by Eli Lilly as the first triple-receptor agonist targeting GLP-1R, GIPR, and GCGR in a single molecule. Researchers who buy retatrutide for laboratory studies use it to investigate metabolic pathways involving appetite regulation, energy expenditure, lipolysis, and hepatic fat metabolism.

Key Research Applications
- Metabolic Research: Simultaneous activation of three receptors modulates energy balance through complementary mechanisms not achievable with single-agonist compounds.
- Obesity and Weight Studies: Published Phase 2 data (NEJM, 2023) showed up to 24.2% mean body weight reduction at 48 weeks.
- Type 2 Diabetes Models: Phase 3 TRANSCEND-T2D-1 data demonstrated HbA1c reductions of 1.7-2.0% and mean weight loss of 36.6 lbs over 40 weeks.
- Hepatic Fat and MASH Research: Glucagon receptor activation promotes lipolysis and fatty acid oxidation in the liver, reducing hepatic fat content.
