Retatrutide (LY3437943) is a multi-receptor peptide agonist evaluated in research exploring metabolic regulation, appetite response, and energy balance. By interacting with GLP-1, GIP, and glucagon receptors, it provides a triple-pathway model for metabolic signal integration and body-weight modulation. EU Pharmaceuticals supplies high-purity, lyophilized Retatrutide for laboratory and educational study of receptor activation, peptide kinetics, and metabolic reference assays.

Key Research Features

• Triple-pathway receptor model: GLP-1R, GIPR, and GCGR engagement.
• Metabolic focus: Studied for appetite signaling, energy expenditure, and glucose balance.
• Extended half-life: Enables once-weekly observation intervals.
• Titration-friendly: Gradual dose escalation supports tolerance and receptor response mapping.

Product Specifications

• Compound: Retatrutide (LY3437943)
• Form: Lyophilized peptide powder
• Content: 10 mg per vial

Research Overview

Retatrutide is investigated as a multi-agonist model peptide influencing GLP-1, GIP, and glucagon signaling cascades. Studies indicate that such receptor co-activation may enhance metabolic outcomes by coordinating energy expenditure, appetite suppression, and glucose regulation through overlapping hormonal pathways. The compound has been explored in once-weekly subcutaneous administration models for extended metabolic monitoring.

Reference Sampling & Handling

• Reconstitution: Add 2 mL bacteriostatic water → 5 mg/mL solution.
• Alternative concentration: 1 mL → 10 mg/mL for compact volume studies.
• Gently roll vial to dissolve; avoid vigorous shaking.
• Storage: Lyophilized: frozen and protected from light; Reconstituted: refrigerate 2–8 °C for up to 30 days.

Reference Sampling Protocol (2.0 mL → 5 mg/mL)

Alternative Sampling (1.0 mL → 10 mg/mL)

1 unit = 0.01 mL. At 5 mg/mL, 1 unit ≈ 0.05 mg; at 10 mg/mL, 1 unit ≈ 0.10 mg.

Reference Frequency & Safety Notes

• Observation interval: Once every 7 days (weekly) is the standard reference cadence.
• Titration: Gradual escalation minimizes GI stress in models; doubling no more than every 4 weeks.
• Upper reference limit: ≤ 12 mg per 7-day cycle.
• Washout period: Minimum 7 days between observations to maintain consistency in receptor data.
• Observed tolerability (literature): Nausea, transient GI upset, dizziness; typically dose-dependent and transient.

How It Works (Mechanism)

• GLP-1 R: Slows gastric emptying and supports appetite-control modeling.
• GIP R: Influences insulin response and metabolic efficiency.
• GCGR: Modulates energy expenditure through hepatic glucose regulation.
• Together, these receptors coordinate multi-hormonal feedback in metabolic regulation assays.
