Product Overview

Retatrutide 20 mg

Compound Overview

Retatrutide 20mg is a research peptide preparation supplied by Amino Apex for qualified laboratory research. Retatrutide, also identified in scientific literature as LY3437943, is a synthetic lipidated peptide developed for activity across three class B G-protein-coupled receptors: the glucose-dependent insulinotropic polypeptide receptor (GIPR), glucagon-like peptide-1 receptor (GLP-1R), and glucagon receptor (GCGR).

Published pharmacological research characterizes LY3437943 as a single-molecule triple receptor agonist with activity across all three receptor systems. Its multi-receptor profile makes retatrutide relevant to laboratory investigations involving receptor activation, peptide-receptor interactions, GPCR signaling, and comparative multi-receptor pharmacology.

Published research describes Retatrutide (LY3437943) as a triple-receptor agonist involving GIP, GLP-1, and glucagon receptor pathways. Additional scientific context is available in the peer-reviewed Retatrutide study published in the New England Journal of Medicine (2023).

Molecular & Structural Research

Retatrutide is a 39-amino-acid synthetic peptide based on a GIP-derived peptide framework. Published structural research describes modifications including non-natural amino-acid substitutions and a fatty-diacid moiety attached through a lysine residue.

These structural features have been investigated in relation to receptor recognition and interaction with GIPR, GLP-1R, and GCGR. Cryo-electron microscopy studies have further characterized the molecular interactions between retatrutide and each of these three receptor systems.

Research Applications

Retatrutide may be used in appropriately designed laboratory research involving:

• GIP receptor signaling
• GLP-1 receptor signaling
• Glucagon receptor signaling
• Multi-receptor agonist characterization
• GPCR activation and downstream signaling
• Peptide-receptor interaction studies
• Comparative peptide pharmacology
• Structure-activity relationship research
• Analytical peptide characterization

These categories describe areas of scientific investigation associated with retatrutide in published research and do not represent therapeutic or clinical-use recommendations.

Analytical Documentation

Amino Apex provides batch-specific analytical documentation for verified lots. Individual lot documentation may include chromatographic purity analysis and other analytical information associated with the tested sample.

Because analytical characteristics may differ by production lot, the Certificate of Analysis for the applicable batch should be used as the source of the measured purity and quality-control results.

Refer to the COA panel on this page or the Amino Apex COA Library for available batch documentation.
