Tiragratide vs Tirzepatide
An educational, source-based comparison of Tiragratide and Tirzepatide — how each peptide works, what it's researched for, and what to know before going deeper.
Investigational triple hormone receptor agonist for metabolic disease.
An investigational peptide agonist targeting GLP-1, GIP, and glucagon receptors. Similar mechanism to retatrutide, designed to maximize weight loss while preserving lean mass through multi-pathway metabolic modulation.
- Obesity and metabolic syndrome
- Type 2 diabetes glycemic control
- NAFLD and liver fat reduction
- • Investigational; not yet FDA-approved.
- • Requires physician oversight in clinical trials.
A dual agonist of the GLP-1 and GIP receptors. The combined incretin action improves glucose control and produces greater weight loss than GLP-1 monotherapy in head-to-head trials.
- Type 2 diabetes (Mounjaro)
- Chronic weight management (Zepbound)
- Sleep apnea in obesity (recent approval)
- • FDA-approved; requires prescription and physician oversight.
- • GI side effects are dose-limiting.
- • Compounded versions are not FDA-evaluated.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Tiragratide | Tiragratide Phase 2 trial in obesity | Diabetes Care | 2025 | Demonstrated significant weight reduction with favorable GI tolerability profile. |
| Tirzepatide | Tirzepatide once weekly for weight management (SURMOUNT-1) | New England Journal of Medicine | 2022 | Up to ~21% mean weight loss at 72 weeks at the highest dose. |
