GLP-3 30MG

Retatrutide 30mg (GLP-3) — Triple Agonist Research Peptide

Retatrutide 30mg — also marketed as GLP-3 — is the highest-volume offering of Combat Research’s GLP-1/GIP/glucagon triple receptor agonist peptide (LY-3437943, CAS 2381089-83-2), engineered for established research programs, high-throughput studies, and laboratories requiring maximum compound availability. Retatrutide simultaneously engages GLP-1, GIP, and glucagon receptors with confirmed ≥99% purity. The 30mg vial offers the best per-milligram value and ensures uninterrupted compound supply for large-scale or long-duration research protocols.

What Is Retatrutide (GLP-3)?

Retatrutide (GLP-3, LY-3437943) is a synthetic triple agonist peptide with high binding affinity across three distinct receptor classes critical to metabolic regulation research:

• GLP-1 receptors (Glucagon-Like Peptide-1) — a primary target in incretin biology, insulin secretion signaling, and appetite regulation pathway research
• GIP receptors (Glucose-Dependent Insulinotropic Polypeptide) — studied for roles in beta-cell response, adipose tissue regulation, and dual incretin signaling
• Glucagon receptors — investigated for hepatic glucose output modulation, energy homeostasis, and counter-regulatory hormone interaction

Retatrutide’s ability to simultaneously activate all three receptor pathways makes it a uniquely powerful research tool for studying multi-receptor coordination, metabolic synergy, and the compound signaling effects that single or dual agonist peptides cannot replicate alone.

Common Research Applications

Retatrutide 30mg (GLP-3, LY-3437943) supports a wide range of high-output research activities:

• High-throughput GLP-1, GIP, and glucagon receptor activation studies
• Long-duration metabolic signaling and pathway analysis programs
• Comprehensive dose-response and receptor saturation studies
• Multi-cohort or multi-arm experimental designs requiring consistent compound supply
• Comparative retatrutide vs. dual vs. single agonist receptor potency research
• Assay development, screening, and optimization pipelines
• Peptide receptor binding kinetics and pharmacodynamic profiling
• Inter-lab reproducibility and method transfer studies
