About Retatrutide
Retatrutide (LY3437943) is a synthetic 39-residue peptide and a single-molecule agonist of three receptors: the glucose-dependent insulinotropic polypeptide receptor (GIPR), the glucagon-like peptide-1 receptor (GLP-1R) and the glucagon receptor (GCGR). This triple-agonist profile makes it one of the most studied research peptides in contemporary metabolic science.
Researchers use retatrutide as a reference compound in receptor-binding assays, cAMP signalling studies, adipocyte and hepatocyte cell models, and comparative work alongside dual agonists such as tirzepatide. Port Peptides supplies retatrutide as a lyophilised research material with batch-level HPLC and mass-spectrometry documentation, available in 20mg, 30mg, 40mg and 60mg strengths.
Research applications
- Tri-agonist receptor pharmacology (GIPR, GLP-1R, GCGR)
- cAMP and downstream signalling assays
- Adipocyte and hepatocyte lipid-metabolism models
- Comparative studies versus mono- and dual-agonist peptides
Mechanism studied
Simultaneous agonism of GIP, GLP-1 and glucagon receptors, used to study integrated incretin and glucagon signalling, thermogenesis and glucose handling in laboratory models.
Also known as: LY3437943, GGG tri-agonist.
