— About this compound
Retatrutide (research code LY3437943) is a single-molecule triple agonist that activates the GIP receptor, the GLP-1 receptor, and the glucagon receptor. The triple-incretin pharmacology represents an attempt to combine the insulin-sensitizing and appetite-modulating effects of GLP-1/GIP agonism with the energy-expenditure effects of glucagon receptor activation.
The compound is currently in late-stage clinical investigation for obesity and type 2 diabetes. Public literature is concentrated in Phase 1–2 trial reports and preclinical pharmacology.
— Mechanism
Picomolar-affinity agonist at GIP, GLP-1, and glucagon receptors. The balanced triple-agonist profile is hypothesized to combine glycemic control (GLP-1/GIP) with increased energy expenditure (glucagon) in metabolic research models.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
