This allows it to influence appetite regulation, energy expenditure, and glucose metabolism at the same time.

Key Research Findings

  • Up to 24.2% average weight loss after 48 weeks in Phase 2 clinical trials.
  • Improved insulin sensitivity.
  • Improved glucose regulation.
  • Reduction in liver fat.
  • Improvements in multiple cardiometabolic markers.

Ongoing Research

Several large Phase 3 clinical trials are currently evaluating the safety and efficacy of Retatrutide in thousands of participants worldwide.
