Liraglutide

Also known as: Saxenda, Victoza

strong human dataFDA approved: Type 2 diabetes (Victoza); chronic weight management (Saxenda)
Mechanism of Action

Liraglutide is a GLP-1 receptor agonist with daily exposure rather than weekly depot kinetics. It supports glucose-dependent insulin secretion and appetite reduction, so ProtoComp treats it as a cabinet signal for lower hunger, nausea watchpoints, and conservative nutrition precision.
