RT3 — Triple Receptor Agonist Research Peptide

RT3 is a next-generation research peptide engineered to simultaneously engage three metabolic receptor targets: GLP-1, GIP, and glucagon receptors. This triple agonist mechanism represents a significant advancement over single- and dual-receptor compounds in preclinical metabolic research.

Mechanism of Action

RT3 activates glucagon-like peptide-1 (GLP-1) receptors to potentiate glucose-dependent insulin secretion, glucose-dependent insulinotropic polypeptide (GIP) receptors to enhance incretin signaling, and glucagon receptors to promote energy expenditure and lipid oxidation. The combined activation of all three pathways creates a synergistic metabolic effect studied extensively in preclinical models of obesity and insulin resistance.

Research Applications

  • Metabolic pathway modulation and energy homeostasis
  • Insulin sensitivity and glucose regulation studies
  • Appetite signaling and food intake research
  • Body composition and lipid metabolism investigations
  • Comparative studies with single- and dual-receptor agonists

Product Specifications

  • Quantity: 10mg per vial
  • Purity: ≥99% (HPLC verified)
  • Form: Lyophilized powder
  • Storage: Refrigerate after reconstitution
  • Testing: USA lab tested, COA available

For research purposes only. Not for human use or consumption.
