Compound Overview
Retatrutide (LY3437943) is a synthetic 39-residue peptide functioning as a triple agonist, engaging the glucagon-like peptide-1 receptor (GLP-1R), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon receptor (GCGR) concurrently. Its sequence incorporates a C20 fatty diacid moiety that extends in vitro stability. In laboratory settings, the compound serves as a reference standard for multi-receptor incretin signaling studies and comparative receptor-selectivity profiling against single- and dual-agonist peptide classes.

Storage & Handling Guidelines
To prevent premature degradation of the peptide bonds and ensure absolute baseline reproducibility across analytical workflows, adhere to the following protocols:
Storage Conditions
Store at −20°C, desiccated, in the original sealed vial. Lyophilized peptide is stable under these conditions for the shelf life stated on its Certificate of Analysis; avoid repeated freeze‑thaw cycling and exposure to ambient humidity once opened.
Atmospheric Separation
Store the target chemical exclusively inside its original, tightly sealed containment unit, completely isolated from ambient humidity, moisture, and localized airflow.
Photolytic Barriers
Protect the compound from direct light and UV exposure by keeping it inside opaque or amber laboratory vessels.
Analytical Auditing
Aether Laboratories implements a strict dual-method verification protocol, combining High-Performance Liquid Chromatography (HPLC) with CHN elemental analysis to independently audit the net mass and absolute purity of our research compounds.
