The field is evolving rapidly, but retatrutide currently holds the weight loss efficacy record among investigational compounds
Improves glycemic control Tirzepatide increases insulin sensitivity, which can lead to a reduction of blood glucose
When maintained in its freeze-dried state, the peptide's amino acid chains remain protected from hydrolysis and degradation processes that typically affect peptide compounds
Brereton, M
Mechanism of Action Peptide Sciences Retatrutide Retatrutide binds and activates three key receptors involved in metabolic regulation: GIP Receptor Agonism: Enhances insulin secretion and promotes nutrient storage GLP-1 Receptor Agonism: Reduces appetite, delays gastric emptying, and supports glucose control Glucagon Receptor Agonism: Increases energy expenditure and fat oxidation This multi-target synergy mimics physiological hormone cascades, offering superior therapeutic potential compared to single-receptor agents
