Retatrutide is the first triple hormone receptor agonist to reach late-stage trials, activating GLP-1, GIP, and glucagon receptors in a single molecule. Semaglutide works on GLP-1 alone. Tirzepatide adds GIP. Retatrutide adds glucagon receptor activity on top of both, and that third mechanism is what separates its research profile from the other two. Why the […]
Semaglutide is a GLP-1 receptor agonist built on the structure of human glucagon-like peptide-1, with two changes that extend its activity: an amino acid substitution that blocks the enzyme DPP-4 from breaking it down, and a fatty acid chain that lets it bind albumin. Native GLP-1 lasts minutes. Semaglutide lasts close to a week. That […]
