Description+
Research-grade Retatrutide is a synthetic triple-receptor agonist supplied as a lyophilized powder for advanced metabolic research. It acts on three pathways at once — GLP-1, GIP, and glucagon — and is sometimes referred to informally as “GLP-3” for this three-receptor mechanism.
Because it engages an additional glucagon pathway beyond dual-agonist compounds, retatrutide is frequently studied alongside semaglutide (a mono-agonist) and tirzepatide (a dual-agonist) to compare multi-receptor pharmacology.
What researchers explore
- Triple receptor activation — studied for simultaneous GLP-1, GIP, and glucagon engagement
- Metabolic research — explored in trials with notable body-composition results
- Glucagon component — linked to thermogenesis and energy-expenditure pathways
- Comparative pharmacology — assessed alongside mono- and dual-agonists
