What Retatrutide is
Retatrutide is a synthetic peptide engineered as a balanced agonist at three receptors: glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP) and glucagon. That triple mechanism distinguishes it from single-agonist and dual-agonist compounds studied in the same metabolic space.
It is supplied as a lyophilised powder in a 10 mg vial, verified to 99%+ purity by HPLC with identity confirmed by mass spectrometry.
What the research literature examines
Published preclinical and clinical research on Retatrutide focuses on receptor co-agonism and downstream metabolic signalling. Study endpoints reported in the literature include body-composition measures, glycaemic parameters and lipid pathways.
This material is supplied strictly for in-vitro laboratory research. UK Peptide does not provide dosing information and the compound must not be administered to humans or animals.

Purity, handling and storage
Store the lyophilised vial at -20°C protected from light. After reconstitution with bacteriostatic water, refrigerate at 2–8°C and use within 14 days. Reconstitute gently down the vial wall and never shake.
