Description
Research Overview
Tirz is a dual GIP/GLP-1 receptor co-agonist — a class of incretin-based research compounds that simultaneously engage both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. This dual receptor activity distinguishes it mechanistically from single-receptor GLP-1 agonists and has made it a significant subject of metabolic research.
As a 39-amino acid synthetic peptide engineered from a GIP peptide backbone, Tirz is studied in preclinical and clinical metabolic models for its role in glycemic regulation, energy homeostasis, and adipose tissue biology.

Scientific Background
Tirz achieves GIP receptor affinity comparable to native GIP while binding the GLP-1 receptor with approximately 5-fold weaker affinity than native GLP-1 — a pharmacological balance that appears to drive enhanced metabolic outcomes relative to selective GLP-1 agonism alone. Research has demonstrated that GIP and GLP-1 receptor co-activation produces synergistic effects on insulin secretion, appetite suppression, and body weight regulation.
The SURPASS clinical trial program, comprising five large-scale randomized controlled trials, has established Tirz as one of the most extensively characterized incretin compounds in metabolic research, with ongoing investigation expanding into cardiovascular outcomes, hepatic steatosis, and neurological applications.
