Description
Retatrutide Research Peptide
Retatrutide, also known as LY3437943, is an investigational synthetic peptide developed as a unimolecular agonist of the GIP, GLP-1, and glucagon receptors. It has become an important research compound in studies of metabolic signaling, receptor pharmacology, glucose regulation, energy balance, and peptide drug design.
Celtek Retatrutide is supplied strictly for laboratory research and development use. Each lot is independently analyzed using HPLC and mass spectrometry, with lot-specific analytical documentation available through our Testing & COA library.

About Retatrutide
Retatrutide is a single engineered peptide designed to activate three related G-protein-coupled receptors:
GIP receptor (GIPR)
GLP-1 receptor (GLP-1R)
Glucagon receptor (GCGR)
This triple-receptor profile distinguishes retatrutide from single GLP-1 receptor agonists and dual GIP/GLP-1 receptor agonists.
Published preclinical and clinical research has examined retatrutide in areas including receptor signaling, metabolic regulation, body composition, glucose metabolism, liver fat, lipid metabolism, and obesity-related disease.
Retatrutide remains an investigational compound and is not an FDA-approved drug.
Independent Analytical Testing
Each Celtek Retatrutide lot is independently analyzed to provide researchers with information about the material being supplied.
Testing includes:
HPLC analysis to characterize chromatographic purity.
Mass spectrometry to provide evidence supporting molecular identity.
The applicable lot number connects the physical research material to its analytical documentation.
Researchers can review current testing through our Testing & Certificates of Analysis section.
Lot-Specific Documentation
We do not rely on a generic purity statement that is reused indefinitely.
Each current lot is associated with its own analytical documentation so researchers can verify the testing connected to the material they receive.
The process is straightforward:
Retatrutide → Lot Number → Analytical Report
This provides clearer traceability between the research material and its supporting data.
