99% Purity Retatrutide Peptide GLP-1 GCGR GIP Triple Agonist CAS 2381089-83-2 for Research Use

99% Purity Retatrutide Peptide GLP-1 GCGR GIP Triple Agonist CAS 2381089-83-2 for Research Use  

Retatrutide is a synthetic 39-amino-acid linear peptide that functions as a triple agonist at three distinct receptor targets: the human glucagon-like peptide-1 receptor (GLP-1R), the glucagon receptor (GCGR), and the glucose-dependent insulinotropic polypeptide receptor (GIPR). It is a unimolecular triple agonist designed to simultaneously activate all three incretin-related receptor pathways. The peptide incorporates a C18 fatty diacid moiety attached via a glutamic acid spacer and two AEEA linkers, which enables strong albumin binding and extended half-life suitable for sustained research dosing schedules.

Retatrutide is supplied as a white to off-white lyophilized powder with ≥99% purity (tested by HPLC). It is available in eight different dosages ranging from 5mg to 60mg per vial (5mg, 10mg, 15mg, 20mg, 30mg, 40mg, 50mg, and 60mg), with a standard pack size of 10 vials per box. Each vial is sealed with an aluminum-plastic flip-off cap and clearly labeled with product name, dosage, and batch number for easy identification and traceability.

For laboratory research purposes only. Not for human or veterinary use. Not for diagnostic or therapeutic applications.

This product is strictly manufactured under GMP-like conditions, ensuring batch-to-batch consistency and reliability. Each batch undergoes rigorous quality control, including HPLC for purity analysis, Mass Spectrometry for molecular weight confirmation, and appearance inspection. Water content and bacterial endotoxin levels are also tested to ensure product integrity. A Certificate of Analysis (COA) documenting all test results is provided with each batch, and third-party testing is available upon request.

Key Research Applications: Triple agonist receptor signaling studies (GLP-1R, GCGR, and GIPR), metabolic pathway research investigating multi-receptor co-activation, incretin hormone mechanism investigations, receptor binding affinity and functional activity assays, in vitro and in vivo laboratory experiments, and peptide-based research compound development.

Storage and Handling: Store lyophilized powder at -20°C, protected from light, and keep the vial tightly sealed to prevent moisture absorption. Under these conditions, the product remains stable for 24 months from the date of manufacture. Once reconstituted with appropriate sterile solvent, the solution should be refrigerated at 2-8°C and used within the recommended timeframe. Avoid repeated freeze-thaw cycles after reconstitution, as this may compromise peptide integrity.

Retatrutide is a high-purity (≥99% by HPLC) triple agonist peptide supplied as a lyophilized powder, ideal for advanced laboratory research applications. With eight available dosages ranging from 5mg to 60mg per vial, it offers flexibility for various experimental setups. Each batch undergoes strict quality control, including HPLC and Mass Spectrometry analysis, ensuring batch-to-batch consistency and reliability. All dosages are in stock with a lead time of 3-5 business days after payment confirmation.
