Description

GLP-3R (LY-3437943) – Triple-Agonist Research Compound

GLP-3R is a lab-made peptide that activates GLP-1, GIP, and glucagon receptors. Therefore, researchers study it for its effects on metabolic pathways. Moreover, studies show strong impacts on weight control, blood sugar balance, and metabolic health. In addition, its triple-action design works more broadly than single-pathway compounds. As a result, scientists see GLP-3R as a key candidate in obesity and diabetes research. Finally, this compound is intended only for laboratory studies and not for human use.


Why Researchers Choose GLP-3R
  • Multi-Receptor Action — Works on GLP-1, GIP, and glucagon receptors to target many pathways [Wikipedia; PeptideFiles; Synapse].

  • Strong Metabolic Results — Early trials showed large weight drops and better metabolic markers [NEJM; MDPI].

  • Clear Dose Response — Higher doses in studies led to stronger results [MDPI; PeptideFiles].

  • Better Tolerance Over TimeInitially, digestive side effects may appear; however, they often improve when the dose is increased more slowly [MDPI; NEJM].

  • Wide Research Use — Studied for obesity, type 2 diabetes, heart health, and liver disease [MDPI; Policy Lab].


Research Data & Handling Tips
  • Stability: Keep refrigerated or frozen as protocols require.

  • Handling: Use sterile methods to prepare and manage solutions.

  • Dosage in Research: Trials tested weekly dosing for weeks to months, with gradual dose increases [MDPI].

  • Solubility & Prep: Mix in suitable buffer, check pH, and avoid particles.

Research

Weight Loss & Obesity

In phase 2 trials, GLP-3R induced weight reductions of ~17.5% by 24 weeks, and up to ~24.2% at 48 weeks at higher doses, compared to placebo. New England Journal of Medicine

Glucose Control & Metabolic Markers

Participants in clinical trials exhibited improvements in HbA1c and fasting glucose, with dose-dependent effects on insulin sensitivity. MDPI

Cardiovascular & Liver Outcomes

Early data show favorable shifts in lipid profiles, reductions in liver fat, and improvements in markers of cardiovascular risk. MDPI

Clinical Trial Status

GLP-3R is in late-phase trials (Phase 3) for obesity, type-2 diabetes, and associated metabolic conditions; several large, multi-center studies are underway. Policy Lab

Mechanism of Action

Mechanism of Action (How GLP-3R Works)

  • Triple Hormone Receptor Activation: GLP-3R simultaneously activates GLP-1, GIP, and glucagon receptors. peptidefiles.com

  • Appetite Modulation: GLP-1 and GIP receptor activation hehttps://www.peptidefiles.com/retatrutilps reduce appetite and slow gastric emptying in laboratory and animal models. MDPI

  • Energy Expenditure & Fat Mobilization: Activation of the glucagon receptor component supports increased energy expenditure and fat metabolism. peptidefiles.com

  • Improved Glucose Homeostasis: Combined incretin effects (GLP-1/GIP) enhance insulin secretion and improve glycemic control in preclinical and early clinical settings. New England Journal of Medicine
