Retatrutide

Triple agonist (GLP-1 / GIP / glucagon) research peptide. Available in 10, 15, and 30 mg vials.

Triple agonistBatch-testedHPLC ≥ 99%

Overview

Retatrutide (research code LY3437943) is a single-molecule triple agonist that simultaneously targets the glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors.

It is one of the most studied next-generation incretin research compounds, of interest in metabolic and body-composition research models for its combined receptor activity.

Current batches are independently verified by an ISO 17025-accredited laboratory — chromatographic purity by HPLC-UV/VIS, plus sterility (USP <71>) and bacterial endotoxin (LAL) testing. See the Certificates of Analysis below.

Mechanism of interest

  • GLP-1 receptor agonism — the most established incretin pathway in metabolic research.
  • GIP receptor agonism — studied alongside GLP-1 for additive incretin effects.
  • Glucagon receptor agonism — investigated for its role in energy expenditure in research models.

Handling & storage

  • Lyophilized powder. Store sealed vials at -20°C; stable for extended periods when kept frozen and dry.
  • Reconstitute with bacteriostatic water. Once reconstituted, refrigerate at 2–8°C and use within the researcher's validated window.
  • Avoid repeated freeze/thaw cycles. Protect from light.
