About Retatrutide
Retatrutide (product code GLP3-R) is a novel synthetic peptide investigated as a triple receptor agonist targeting the GIP, GLP-1, and glucagon receptors simultaneously. Phase-2 clinical studies published in 2023 reported the largest weight reductions of any incretin-family compound tested to date, positioning retatrutide as a leading research target in metabolic-syndrome and obesity biology.
All retatrutide supplied by BioInfinity is manufactured by solid-phase peptide synthesis (SPPS), purified by reverse-phase HPLC, and confirmed by mass spectrometry to >99% purity. It ships as a lyophilized white powder in a septum-sealed 5 mg or 10 mg vial, ready for reconstitution with bacteriostatic water for laboratory use.
