The mechanism overview below explains why GLP-R targets three receptor pathways instead of one.
Why GLP-R
Three Receptor Pathways. One Reference Peptide.
GLP-R is our reference research peptide for studying three hormone pathways — GLP-1, GIP, and glucagon — together instead of one at a time. Most research so far has looked at these pathways separately. Studying all three at once is newer territory, and GLP-R gives researchers a consistent, verified compound to work with as that research develops.
