- Tirzepatide
- Dual GIP/GLP-1 agonist
- ~5 days
- Adipocyte lipolysis regulation + insulin secretion + gastric emptying delay
- 20.9% mean weight reduction (SURMOUNT-1, 72 weeks)
- Best choice when hepatic steatosis, lipid panel improvement, or maximal weight reduction are research endpoints
- Semaglutide
- GLP-1 receptor selective
- Insulin secretion + gastric emptying delay + hypothalamic appetite suppression
- 14.9% mean weight reduction (STEP-1, 68 weeks)
- Strong option when appetite suppression and glycemic control are primary. Lacks direct adipocyte effects
- Liraglutide
- ~13 hours
- Insulin secretion + gastric emptying delay (shorter duration)
- 8.0% mean weight reduction (SCALE trial, 56 weeks)
- Daily dosing required; lower efficacy ceiling but well-established safety profile for longer-term studies
- This table compares the three most-studied peptides for metabolic syndrome research based on published Phase 3 trial data. Tirzepatide's dual-agonist mechanism produces the largest effect sizes across weight loss and metabolic endpoints, but semaglutide remains the most widely used GLP-1 compound in research due to established protocols and availability. Liraglutide's shorter half-life limits its use in once-weekly intervention studies but offers flexibility for dose-titration research requiring rapid washout.
