Overview
Retatrutide (CAS 2381089-83-2): Research Compound Overview
Retatrutide is a synthetic single-chain peptide catalogued by livvmore for laboratory research applications. It is identified by CAS number 2381089-83-2 and carries a molecular weight of 4731.33 g/mol. Each unit is supplied as a lyophilized powder in 10 mg and 30 mg vial formats, accompanied by batch documentation and a certificate of analysis on request.
Within the scientific literature, retatrutide is classified as a synthetic triagonist peptide: a single molecule engineered to engage three distinct receptor targets. It sits within the broader family of GLP research peptides that laboratories catalogue and characterise by receptor affinity, molecular structure and analytical profile. This page describes the compound’s identity and the research topics it appears under. No health, medical, therapeutic or performance claims are made or implied.
Understanding Retatrutide
Retatrutide is an acylated peptide built on a modified peptide backbone carrying a lipid side chain, a design that supports extended circulation in laboratory models. It is studied as a unimolecular triagonist, meaning one peptide sequence engages the GLP-1 receptor, the GIP receptor and the glucagon receptor together rather than through separate molecules.
- Compound class: synthetic acylated peptide (triagonist)
- Receptor targets referenced in the literature: GLP-1, GIP and glucagon receptors
- CAS number: 2381089-83-2
- Molecular weight: 4731.33 g/mol
- Physical form: lyophilized powder, 10 mg and 30 mg vials
Investigators typically confirm the identity and structural characterisation of each batch using analytical methods such as HPLC and mass spectrometry, with results recorded in the accompanying certificate of analysis.
Why Retatrutide is studied
Retatrutide draws research interest because its triple-receptor design offers a single-molecule model for examining how incretin and glucagon receptor pathways engage together under controlled, in-vitro and cellular conditions. Comparative peptide pharmacology, receptor-binding characterisation and structure-activity investigation are recurring themes across the published record.
- Peptide receptor signalling across multiple receptor families
- Structure-activity relationships of acylated, long-acting peptide analogues
- Receptor-binding and selectivity profiling in cellular studies
- Comparative molecular characterisation against other GLP research peptides
All such work is confined to the laboratory. livvmore supplies retatrutide strictly as a research material for qualified investigators and offers no guidance for any non-laboratory application.

What each batch record documents
Every batch is accompanied by laboratory records. The entries below describe what each record documents.
Mass (LC-MS)
Mass spectrometry records the compound’s measured mass to document molecular identity.
Appearance
The physical appearance of the material is recorded, for example a white lyophilized powder.
Batch record
Each batch is logged with a lot number and production date for traceability.
These are records of laboratory testing carried out on the batch. They document compound identity for research use and are not a statement of safety, suitability, or fitness for any use.
Research information
Research context
Retatrutide has become a frequent reference point in peptide receptor pharmacology, where investigators study synthetic triagonists that address more than one receptor with a single sequence. Published laboratory and molecular work characterises its receptor-binding profile, structural features and its relationship to earlier incretin-class peptides. livvmore catalogues the compound by molecular identity so that researchers can source a consistent, batch-documented material for their own in-vitro and laboratory investigation.
Research themes commonly associated with retatrutide across the scientific record include:
- Receptor-binding and selectivity characterisation across GLP-1, GIP and glucagon receptors
- Structure-activity relationships of acylated, long-acting peptide analogues
- Peptide receptor signalling examined in cellular and in-vitro systems
- Analytical characterisation of peptide identity and purity by HPLC and mass spectrometry
- Comparative molecular profiling against single- and dual-receptor GLP research peptides
