Description

Retatruide

Retatrutide, research code LY3437943, is a cutting-edge synthetic polypeptide containing 39 amino acids, independently developed as a triple-target metabolic regulator. It can simultaneously activate three core metabolic receptors: GLP‑1R, GIPR and GCGR, which makes it far more comprehensive in regulating fat metabolism, blood glucose balance and energy expenditure than traditional dual-target agonists such as Tirzepatide and Semaglutide.

Our Retatrutide is manufactured through strict solid-phase peptide synthesis (SPPS) technology, followed by professional low-temperature lyophilization treatment. The finished product is pure white crystalline powder without any mannitol, lactose or other excipients. Every batch undergoes full-spectrum laboratory testing to ensure stable biological activity, low impurity content and repeatable experimental data, widely supplied to university research laboratories, biotech R&D companies, pharmaceutical preclinical research teams and medical research institutions all over the world.

This product is strictly classified as laboratory research grade, only applicable to in vitro cell experiments and in vivo animal model trials.
