Retatrutide (LY3437943) is a synthetic, single-peptide chain consisting of 39 amino acids. It is a pioneering multi-receptor agonist engineered to target three distinct metabolic pathways simultaneously.
This compound is manufactured strictly for in-vitro and laboratory research purposes. In biochemical, physiological, and metabolic studies, Retatrutide is primarily investigated for its triple agonism of the gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon (GCG) receptors. Researchers study its effects on:
Triple-Receptor Synergism: Analyzing how simultaneous activation of GIP, GLP-1, and glucagon receptors cross-amplifies downstream cellular signaling compared to mono- or dual-agonists. [11]
Pancreatic and Hepatic Kinetics: Investigating insulin secretion mechanisms, glucagon production regulation, and lipid metabolism within isolated liver and tissue models.
Energy Expenditure Pathways: Evaluating its specific impact on the glucagon receptor pathway to observe cellular thermogenesis, fat oxidation, and metabolic rate shifts.
Guaranteed Sterility & Zero Contamination
Our manufacturing process adheres to strict laboratory standards to ensure maximum experimental control.
Zero Pollution: The compound is completely free of heavy metals, residual solvents, or chemical pollutants that could skew research data.
Validated Sterility: Every batch undergoes rigorous sterilization processes and is sealed in a sterile environment to guarantee zero bacterial or microbial contamination.
Chemical and Physical Profile
Sequence: Exact 39-amino acid engineered peptide backbone with a C18 fatty diacid moiety
Molecular Weight: ~4731.3 g/mol
Form: Lyophilized (freeze-dried) sterile powder requiring reconstitution for assay use
Purity Standard: ≥ 99.7% verified via High-Performance Liquid Chromatography (HPLC) and mass spectrometry
Storage and Stability Guidelines
To maintain the structural integrity of the peptide and prevent degradation, adhere to the following storage protocols:
Short-Term Storage (Lyophilized Powder): Can be kept at room temperature (15°C to 25°C) for up to 4 to 6 weeks. It is highly stable in dry, freeze-dried form. [21, 22]
Long-Term Storage (Lyophilized Powder): Must be stored in a standard freezer at -20°C or below for up to 2 years. [23, 24, 25, 26]
Post-Reconstitution Storage (Liquid Form): Once mixed with a bacteriostatic or sterile water solution, the vial must be stored in a refrigerator (2°C to 8°C). It remains stable for up to 30 days. Do not freeze after reconstitution, and avoid shaking the vial, as physical agitation can break the delicate peptide bonds.
Quality Guarantee and Testing Incentives
We stand behind the absolute purity of our research compounds. To ensure complete transparency and scientific accuracy, we offer the following guarantees:
Purity Guarantee: Every batch is verified to meet or exceed 99.8% purity. If you conduct an independent third-party purity test (such as HPLC/MS) and the results fall below 98%, we will issue a full 100% refund for your purchase.
Lab Testing Rewards: If you conduct independent laboratory testing under our company’s name and share the official access credentials or raw data reports with us, we will credit your account with £90 in Lab Credits toward your next order
