Efficacy and safety of retatrutide, a novel GLP-1, GIP, and glucagon receptor agonist for obesity treatment: a systematic review and meta-analysis of randomized controlled trials

Systematic Review With Meta-Analysis

Retatrutide (LY3437943) for metabolic disorders: A systematic review of clinical outcomes in obesity and type 2 diabetes

A new weight-loss drug called retatrutide might help people with obesity lose about a quarter of their body weight in less than a year—and it could work even better and faster than weight-loss surgery or other medicines we have now.
