Product Overview

Research-Grade Peptide Raw Material for Analytical and Nonclinical R&D

Form note: CAS information is provided for identification. Confirm the required salt or counter-ion form before ordering.

Product Overview

Retatrutide, also known as LY3437943, is an investigational peptide designed as a single-molecule agonist of the GIP, GLP-1 and glucagon receptors. Its multi-receptor profile makes it a valuable research material for studying receptor selectivity, signalling balance, peptide engineering and metabolic pathway interactions.

ASCENT supplies Retatrutide as a peptide raw material for analytical, laboratory and nonclinical research. It is not supplied as a finished drug product, injection, kit or consumer-use formulation.

Mechanism and Research Value

Retatrutide activates the receptors for glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1 and glucagon. Its triple-receptor activity provides a useful platform for investigating how receptor balance influences downstream signalling and metabolic responses.

Research interest includes multi-agonist peptide design, comparative receptor pharmacology, structure-activity relationships, lipidated peptide engineering, albumin-binding strategies and analytical characterization of complex modified peptides.
