Retatrutide (LY-3437943)
Triple-agonist peptide under clinical investigation — educational overview. Informational Only
Overview
Dragon Pharma Retatrutide (LY-3437943) is an investigational peptide being studied for its potential to
support weight management and metabolic health. It is not approved for routine clinical use and should only
be accessed within regulated clinical trials or as permitted by applicable law.
Mechanism: How It Works
Retatrutide is a GIP/GLP-1/glucagon receptor triagonist, designed to engage three
hormone-signaling pathways involved in appetite, glucose regulation, and energy expenditure:
- GIPR (glucose-dependent insulinotropic polypeptide): influences energy balance and fat storage.
- GLP-1R (glucagon-like peptide-1 receptor): associated with satiety and support of insulin secretion.
- Glucagon receptor: may increase energy expenditure and fat oxidation.

Potential Effects (Research Context)
- Reductions in body weight and adiposity (under investigation).
- Improvements in glucose control and insulin sensitivity (under investigation).
- Decreased appetite and food cravings (reported in early studies).
- Possible increases in energy expenditure and metabolic flexibility (mechanistic rationale).
Findings come from ongoing/early-phase research and may change with further study.
Safety & Side Effects
Reported side effects in trials of incretin-based therapies can include gastrointestinal symptoms (e.g., nausea,
bloating, constipation or diarrhea), headache, fatigue, and transient changes in heart rate or labs. Incidence and
severity can vary by dose and individual factors.
Seek guidance from a licensed clinician for personalized risk–benefit assessment. Do not start, stop, or change any
