Research Notes
- Simultaneous activation of GLP-1, GIP, and glucagon receptors
- Phase 2 clinical studies have been published examining body-weight endpoints (see research overview)
- Glucagon receptor agonism is hypothesized to influence energy expenditure relative to dual agonists
Overview (Research Use Only)
Retatrutide is a triple incretin receptor agonist peptide supplied by Sealed Peptides for laboratory and research use only. This compound is designed to simultaneously engage GLP-1, GIP, and glucagon receptors.
This product is not intended for human consumption, clinical administration, or any diagnostic, therapeutic, or preventive use. All handling should follow institutional laboratory policies for research chemicals.
Research context
Preclinical and early clinical research has examined triple GLP-1/GIP/glucagon receptor agonism for metabolic and body composition endpoints. The glucagon receptor component distinguishes this class from dual agonists, with researchers hypothesizing enhanced energy expenditure effects. Published Published Phase 2 clinical studies have reported on body-weight endpoints in study populations.
Findings in clinical or preclinical systems do not establish safety or efficacy for any indication and must not be interpreted as medical claims.
