1. Product Overview

Retatrutide is a synthetic peptide analog that functions as a triple agonist of the glucagon-like peptide-1
(GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon (GCG) receptors. It is a linear peptide
composed of 39 amino acids that has been chemically modified with a C20 fatty diacid chain attached via a
gamma-glutamic acid spacer. This structural modification allows for albumin binding and resistance to enzymatic
degradation, thereby extending its half-life in research models.

In research settings, this compound is utilized to study metabolic pathways, insulin secretion mechanisms,
appetite regulation, energy expenditure, and the physiological effects of multi-receptor agonism. It serves as a
critical tool for investigating the pathophysiology of type 2 diabetes, obesity, metabolic syndrome, and
cardiovascular metabolism in non-clinical models.

3. Research Applications

Retatrutide is intended exclusively for use in qualified research laboratories. Common areas of investigation
include:

• Metabolic Regulation: Investigation of triple receptor agonism (GLP-1/GIP/GCG) on glucose
  homeostasis, insulin secretion, glucagon action, and lipid metabolism in cellular assays.
• Receptor Binding Affinity: In vitro studies measuring binding kinetics, selectivity, and
  potency at GLP-1, GIP, and glucagon receptors.
• Cellular Signaling: Analysis of cAMP production and downstream signaling pathways in pancreatic
  beta-cell lines and hepatocytes.
• Adiposity and Energy Balance: Research into the mechanisms of weight regulation, satiety
  signaling, gastric emptying, thermogenesis, and energy expenditure in animal models (subject to institutional
  ethical approval).
• Comparative Pharmacology: Studies comparing single versus dual versus triple receptor agonism
  effects on metabolic outcomes.

4. Storage and Handling

Proper storage is essential to maintain the stability and integrity of the peptide. Please adhere to the following
guidelines:

Storage of Lyophilized Powder

• Long-term Storage: Store at -20°C (-4°F) or colder. Stable for up to 2 years if kept desiccated
  and away from light.
• Short-term Storage: Can be stored at 2-8°C (36-46°F) for up to 3 months.
• Room Temperature: Avoid prolonged exposure to room temperature. Transport should be conducted
  with cold packs.

Reconstitution and Handling

• Allow the vial to reach room temperature before opening to prevent condensation.
• Reconstitute using Sterile Water for Injection (SWFI) or Bacteriostatic Water. Gently swirl the vial; do not
  shake vigorously.
• Once reconstituted, the solution should be stored at 2-8°C and used within 14-21 days. Do not freeze after
  reconstitution as freeze-thaw cycles degrade the peptide structure.
• Use appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection, when
  handling this substance.

5. Safety and Hazard Information

While this product is not classified as a dangerous good for transport, standard laboratory safety protocols must
be observed.

• Potential Hazards: May cause irritation to skin, eyes, and respiratory tract. Avoid inhalation
  of powder.
• First Aid:
  • Skin Contact: Wash thoroughly with soap and water.
  • Eye Contact: Rinse cautiously with water for several minutes.
  • Ingestion: Rinse mouth. Do NOT induce vomiting. Seek medical advice.
• Disposal: Dispose of contents/container in accordance with local, regional, and national
  regulations regarding chemical waste.
