Retatrutide (LY3437943) is a synthetic peptide that acts as a triple receptor agonist, simultaneously activating three metabolic receptors: GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon receptors. This triple agonist mechanism is unique in the incretin peptide class and has generated significant interest in metabolic research.
Developed by Eli Lilly, retatrutide represents the next generation of multi-agonist metabolic peptides. While semaglutide targets one receptor and tirzepatide targets two, retatrutide's three-receptor engagement allows researchers to study the combined and synergistic effects of all three metabolic signaling pathways in preclinical models.
For an in-depth analysis of retatrutide's molecular structure and preclinical findings, see our Retatrutide Research Peptide Guide.
Retatrutide has become a focus of metabolic research due to its unique triple agonist mechanism. Key research applications include:

Retatrutide is a triple receptor agonist that activates GLP-1, GIP, and glucagon receptors simultaneously. This distinguishes it from tirzepatide (dual agonist) and semaglutide (single agonist). See our triple vs dual agonist comparison.
Research-grade retatrutide is available in 5mg, 10mg, and 30mg lyophilized vials. PeptidesATX offers all three sizes with batch-specific COA documentation.
Store lyophilized retatrutide at -20°C or below, protected from light and moisture. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 3-4 weeks. See our storage guide.
Research-grade retatrutide should have ≥98% HPLC purity with mass spectrometry confirmation. PeptidesATX provides 99%+ purity with batch-specific COA documentation.
