Retatrutide is an investigational compound and is not an FDA-approved drug.
This listing is for bulk peptide/API material supplied to qualified B2B customers for lawful research, development, analytical or other permitted professional applications, subject to applicable regulations.
The product is supplied as bulk powder and is not offered as a finished dosage form or for direct consumer use.

Solubility: The lyophilized powder can be reconstituted with suitable aqueous buffer according to laboratory experimental protocols. It is recommended to prepare sub-packaged aliquots after reconstitution to avoid repeated freeze-thaw cycles which may cause molecular degradation.
Storage requirement: Sealed storage at -20℃, protected from light and humidity. Keep away from frequent temperature fluctuation.
Shelf life: 24 months under recommended storage conditions (unopened vial). Once reconstituted, use within a short period following lab SOP.
Packaging options: Standard vial packing in 5mg,10mg,15mg,20mg; custom packaging and bulk supply are negotiable for laboratory project demand.

We adopt standardized peptide purification and inspection process. Each production batch undergoes full analysis: HPLC purity detection, moisture test, residual solvent inspection, endotoxin test and related substance analysis, to guarantee consistent quality and repeatable experimental data for customers’ research projects.

Retatrutide is a single-molecule triple receptor agonist peptide. Compared with single or dual receptor agonist peptide reagents, this molecule can interact with three class B G-protein coupled receptors simultaneously. It is a popular research tool in academic and industrial labs for exploring the interaction between multiple hormone receptor signaling networks. The structural modification design of this peptide has been documented in multiple published preclinical literature for reference in peptide chemistry and molecular pharmacology research.

Prepare suitable sterile aqueous buffer such as PBS or acetic acid solution according to your experimental scheme.
Add buffer solvent slowly to the vial. Do not shake vigorously. Gentle swirling is recommended to dissolve the lyophilized peptide powder.
After complete dissolution, aliquot the peptide solution into small centrifuge tubes to avoid repeated freeze-thaw cycles.
Reconstituted solution should be stored at -20℃ or -80℃ based on your experimental requirements.
