What is Retatrutide?
Retatrutide (LY3437943) is a peptide developed by Eli Lilly that acts simultaneously on three metabolic receptors:
- GLP-1 — reduces appetite and slows gastric emptying
- GIP — improves insulin secretion and fat metabolism
- Glucagon — increases energy expenditure and lipid oxidation
This triple action produces unparalleled fat loss: -24% in 48 weeks in phase 3 clinical trials, compared to -15% for high-dose semaglutide.
