Retatrutide: The New Triple-Agonist Weight Loss Treatment
Retatrutide (LY3437943) is an experimental triple-agonist ("triple-G") weight loss medication in phase 3 clinical trials, developed by Eli Lilly to target GLP-1, GIP, and Glucagon receptors. Phase 2 data suggests it may outperform current treatments with potential weight reductions nearing 30%, though it is not yet approved for public use. The upcoming TRIUMPH-1 trial results are critical for its future regulatory approval, expected around 2026.
