Retatrutide Research Peptide — Buy Triple Receptor Agonist GLP-1/GIP/Glucagon (≥97% Purity)
Retatrutide (CAS 2381272-15-5) is a next-generation synthetic peptide engineered as a triple co-agonist at the GLP-1R, GIPR, and glucagon receptor (GCGR). Representing the leading edge of incretin pharmacology research, retatrutide builds on the dual-agonist mechanism of tirzepatide by adding glucagon receptor activity — enabling investigation into the additive metabolic effects of all three incretin axes simultaneously. It is among the newest and most sought-after research peptides in metabolic biology.
Mechanism of Action
Retatrutide activates three complementary GPCRs: GLP-1R drives insulin secretion and appetite suppression; GIPR augments insulin response and modulates adipose tissue; GCGR activation increases hepatic glucose output, promotes lipolysis, and raises energy expenditure. The net effect in research models involves substantial changes in energy balance, lipid mobilization, and glucose homeostasis — providing a uniquely comprehensive tool for studying multi-receptor metabolic regulation.
