Microscopically, transmural hyperemia of the gastrointestinal tract, intestinal mucosa villi reduction, crypt reduction with focal denudation of superficial epithelia, and large bowel dilatation were all inhibited

Key Takeaways Gastrointestinal events are the most common adverse effects: Nausea, diarrhea, and vomiting were reported in 4067% of participants at higher doses in published Phase 2 trial data Adverse events are dose-dependent: Higher retatrutide doses consistently produced higher rates of GI events across all published trials Most adverse events were mild to moderate: The Phase 2 trial reported the majority of events as Grade 1-2 in severity Discontinuation rates ranged from 610%: Published data shows dropout rates due to adverse events were comparable to other GLP-1 class compounds Retatrutide is not FDA-approved: All safety data comes from investigational clinical trials it remains a research compound What Clinical Trials Tell Us About Retatrutide Adverse Events Retatrutide (LY3437943) is an investigational triple-agonist peptide targeting GLP-1, GIP, and glucagon receptors simultaneously

These naturally occurring compounds have excellent biocompatibility with minimal risk of adverse reactions

Some are generally considered safe to use while others are available for research use only
