Tirzepatide Research Peptide: Dual-Agonist Mechanism and Study Results
Tirzepatide activates two receptors, GIP and GLP-1, built into a single 39-amino acid peptide. That dual mechanism is why researchers treat it as a distinct case rather than a simple upgrade on single-agonist compounds like semaglutide. Two Receptors, One Molecule GIP and GLP-1 both stimulate insulin release, but through separate receptors and separate downstream signaling. […]
