Retatrutide
Triple GLP-1/GIP/glucagon receptor agonist (investigational) · Pre-filled pen
Retatrutide is an investigational triple agonist designed to engage GLP-1, GIP and glucagon receptors. The GLP-1 and GIP actions influence insulin secretion, appetite and satiety, while glucagon-receptor activation is studied for its potential to increase energy expenditure and fat oxidation. It is being evaluated in advanced clinical trials for weight and metabolic endpoints.
Studied use areas
- Body-weight reduction under clinical-trial investigation
- Glycaemic-control research
- Appetite and satiety signalling
- Energy-expenditure and fat-oxidation endpoints
Safety & status
- Investigational agent that is not yet approved; as a GLP-1-class compound it would be prescription-only in the EU and UK (EMA/MHRA) and requires physician supervision
- Gastrointestinal effects seen with incretin agonists (nausea, vomiting, diarrhoea) are expected during trials
- Long-term safety is not yet established outside the clinical-trial setting
- No dosing is provided here; any regimen is individualised and determined by the treating physician
⚕ Clinical note: This is educational information, not medical advice. Retatrutide is an investigational, late-phase compound; it is not an approved product, and any exposure should occur only under qualified physician supervision within an appropriate clinical framework.
