What is GLP-3 R?
GLP-3 R, also known by its development code LY3437943, is a synthetic single-chain peptide investigated as a triple hormone-receptor agonist with activity at the GIP, GLP-1, and glucagon receptors. It is supplied as a lyophilized powder for in-vitro laboratory research use only.
GLP-3 R research
Published work on GLP-3 R is qualitative in the framing below. Each item describes the focus of the research itself, not an outcome for any person.
- Energy metabolism and body-weight regulation. GLP-3 R has been the subject of animal and clinical studies exploring its role in models of energy balance and body-weight regulation.
- Glucose handling. Studies have examined the compound in research contexts related to glucose handling and metabolic signaling.
- Triple-agonist mechanism. Research has characterized the combined engagement of the GIP, GLP-1, and glucagon receptors by a single molecule.
- Hepatic and adipose research. Investigations have looked at endpoints such as hepatic fat content within study populations, alongside adipose-tissue measures.

GLP-3 R FAQ
What is GLP-3 R (LY3437943)?
GLP-3 R, development code LY3437943, is a synthetic single-chain peptide investigated as a triple hormone-receptor agonist with activity at the GIP, GLP-1, and glucagon receptors. It is supplied as a lyophilized powder for in-vitro laboratory research use only.
What purity does PeptideX1 GLP-3 R meet?
Each batch is ≥99% purity by HPLC, verified per batch on the accompanying Certificate of Analysis.
Is a Certificate of Analysis included?
Yes. A batch-specific Certificate of Analysis is included with every order.
How is it shipped and stored?
It ships lyophilized, sealed and desiccated. Store the sealed vial at -20°C and protect it from light.
Is GLP-3 R similar to Ozempic or tirzepatide?
GLP-3 R (LY3437943) is a research peptide studied as a triple GIP, GLP-1, and glucagon receptor agonist, a broader mechanism than single GLP-1 agonists such as semaglutide (marketed as Ozempic) or the dual agonist tirzepatide. PeptideX1 supplies GLP-3 R strictly for in-vitro laboratory research. It is not a weight-loss product and not a substitute for any prescription medication.
Is this product for human use?
No. It is sold strictly for in-vitro laboratory research use only. It is not for human or veterinary use.
