What Is Retatrutide (LY3437943)?
Retatrutide is a triple-agonist peptide investigated for simultaneous activation of GLP-1, GIP, and glucagon receptors in metabolic research models.
- GLP-1 receptor — satiety signaling, glycemic control pathways
- GIP receptor — complementary incretin activity
- Glucagon receptor — lipid and thermogenic signaling roles
Supplied for in-vitro/ex-vivo research by qualified laboratories; not for administration to humans or animals.
Mechanistic Overview
- GLP-1 axis: satiety signaling & glucose dynamics
- GIP axis: glucose-dependent insulin modulation
- Glucagon axis: lipid mobilization & energy expenditure pathways
Research Evidence Snapshot
Published preclinical and Phase 2 literature describes metabolic endpoints associated with triple-agonist peptides when compared to single- and dual-agonist incretin approaches.
Researchers should review primary sources for dosing paradigms, titration framework, and protocol details relevant to their own models.
Retatrutide vs Tirzepatide vs Semaglutide
| Feature | Retatrutide | Tirzepatide | Semaglutide |
|---|---|---|---|
| Agonism | Triple: GLP-1, GIP, Glucagon | Dual: GLP-1, GIP | Single: GLP-1 |
| Research Focus | Combined metabolic signaling | Incretin synergy | Satiety signaling |
| Design Notes | Incorporates glucagon-axis activity | Well-studied dual incretin profile | Single-pathway incretin agent |

Katy –
Observations in my research have been impressive so far. The compound appears to strongly influence appetite-related pathways and significantly reduce cravings in testing environments, even during periods when cravings are typically elevated. After about 30 days of consistent research, measurable progress was recorded. Very satisfied with the quality and purity of this Retatutrid and will continue future research.
