GLP3-RT — 20MG

£120.00

GLP3 – RT (LY3437943) is an investigational once-weekly injectable peptide developed by Eli Lilly. It is a single-molecule triple agonist that simultaneously activates three G-protein-coupled receptors involved in metabolic regulation: the glucose-dependent insulinotropic polypeptide receptor (GIPR), the glucagon-like peptide-1 receptor (GLP-1R), and the glucagon receptor (GCGR).

This distinguishes it from earlier incretin-based therapies: single GLP-1 receptor agonists (e.g., semaglutide) and dual GIP/GLP-1 agonists (e.g., tirzepatide). GLP3 – RT is engineered as a modified peptide (built on a GIP backbone with amino acid substitutions for DPP-4 resistance and a fatty diacid moiety for albumin binding), giving it a plasma half-life of roughly 6 days that supports once-weekly subcutaneous dosing.
