The Glucagon Pathway
Thermogenesis, hepatic fat mobilization, and the GLP-1 counterbalance
The Differentiator
This is what makes retatrutide different from everything else on the market. The glucagon receptor -- traditionally feared for raising blood sugar -- turns out to be a powerful thermogenic lever when co-activated with GLP-1. This unit explains how glucagon agonism drives energy expenditure, mobilizes liver fat, and why GLP-1 co-agonism prevents the hyperglycemia that would otherwise make this approach unsafe.
Glucagon Receptor Biology
