Retatrutide

GGG triple agonist (GLP-1 / GIP / glucagon receptor)

Retatrutide is a single engineered peptide that speaks to three of the body's own metabolic signals at once — GLP-1, GIP, and glucagon. It is the most advanced of the so-called triple agonists, and in research it has drawn attention for the depth of its effects on body weight and metabolic markers. Among incretin-based investigational compounds, it is often described as the next step beyond the dual agonists.
