Information for Tirzepatide
Tirzepatide (LY3298176) is a 39-amino acid synthetic peptide designed as a dual agonist of GIP and GLP-1 receptors, exhibiting a prolonged half-life due to a C20 fatty diacid side chain that promotes albumin binding (Chavda et al. 2022). Experimental models show its dual receptor activation enhances metabolic regulation and induces dose-dependent reductions in fat mass with a preference for adiposity over lean mass (Min & Bain 2020; Karagiannis et al. 2022; Sokary & Bawadi 2025).
