This heightened sensitivity may represent an early or mild form of the same process that produces full allodynia at higher intensities

Other Key Findings Metabolic improvements: Participants saw reductions in A1C (for those with prediabetes or diabetes), fasting glucose, and triglycerides Liver fat reduction: Retatrutide reduced liver fat by up to 50%, which is why Eli Lilly added a NASH-specific trial to the Phase 3 program Side effects: Mostly gastrointestinal (nausea, diarrhea, constipation), similar to other GLP-1 drugs but manageable with slow titration Discontinuation rate: About 10% of participants stopped due to side effects, comparable to tirzepatide and semaglutide Study limitation: The Phase 2 trial was only 48 weeks long
Tirzepatide represents the next generation of incretin therapy with potentially even greater efficacy, and retatrutide may push the boundaries further still
