Description
Retatrutide (LY3437943) is a novel triagonist peptide that activates GLP-1, GIP, and glucagon receptors. It is studied for its profound effects on weight management, glucose control, and metabolic health, representing one of the most advanced incretin-based therapies in development.
Benefits
- Weight management — studied for dramatic body weight reductions in phase 2 trials.
- Glucose control — linked to improved HbA1c and insulin sensitivity in type 2 diabetes.
- Metabolic health — explored for cholesterol, liver fat reduction, and energy regulation.
- Triple pathway synergy — combines GLP-1, GIP, and glucagon receptor activity.
- Next-gen incretin — developed as a cutting-edge obesity and diabetes research tool.
What researchers look at
- Triagonist activity: simultaneous activation of GLP-1, GIP, and glucagon receptors.
- Phase 2 clinical trials reporting unmatched weight loss efficacy.
- Head-to-head comparisons with semaglutide and tirzepatide.
- Exploration of cardiometabolic, hepatic, and long-term safety outcomes.
