The added pathway. R3 adds glucagon-receptor agonism on top of the GIP and incretin pathway activity shared with TZ2. Research models use the pair to study the incremental contribution of glucagon-receptor signaling to metabolic endpoints.
Why they are compared. They share the GIP+incretin pathway base, so the comparison isolates the role of the third (glucagon) receptor in next-generation incretin research.

Frequently asked questions
What is the difference between R3 and TZ2?
R3 is a triple agonist (GIP, incretin pathway, and glucagon receptors); TZ2 is a dual agonist (GIP and incretin pathway). The glucagon-receptor activity is the key distinction. Both are Research Use Only.
Why add glucagon-receptor activity?
In research models the glucagon receptor is studied for its role in energy expenditure and lipid metabolism; R3 lets researchers investigate triple-pathway signaling versus dual.
