GLP-3 RETA “Triple G”

GLP-3 RETA “Triple G” refers to retatrutide, also identified in scientific literature by the research designation LY3437943. Retatrutide is a synthetic peptide developed for research involving multiple metabolic receptor-signaling pathways.

Retatrutide is characterized as a triple receptor agonist with activity at the glucose-dependent insulinotropic polypeptide (GIP) receptor, glucagon-like peptide-1 (GLP-1) receptor, and glucagon receptor. This three-receptor profile is the basis for the commonly used “Triple G” designation.

Although “GLP-3” is sometimes used informally to describe retatrutide, it does not represent an actual GLP-3 receptor or scientifically recognized peptide class. Retatrutide is more accurately described as a GIP/GLP-1/glucagon triple receptor agonist.

Its defined peptide structure makes retatrutide a compound of interest for controlled laboratory investigations involving receptor interactions, peptide characterization, molecular signaling, and related biochemical pathways.
