Retatrutide – Research-Grade Triple-Receptor Peptide | 10 mg | Liquilabs Certified

Retatrutide (LY3437943) is one of the most advanced multi-receptor peptide agonists currently studied in metabolic and obesity research. No other peptide supplier in the Netherlands offers Retatrutide with the analytical depth of batch RGXRETA10-2602-01 — certified >99.8% pure by Liquilabs with a perfect identity match score of 1.00.

What is Retatrutide?

Retatrutide is a synthetic peptide designed as a simultaneous agonist of three distinct G-protein coupled receptors: GIP (glucose-dependent insulinotropic polypeptide receptor), GLP-1 (glucagon-like peptide-1 receptor), and glucagon receptor. This triple-receptor activity profile makes Retatrutide one of the most complex and scientifically compelling peptides in current metabolic research, distinguishing it from dual agonists like Tirzepatide.

Research applications include:

• Triple receptor (GIP/GLP-1/glucagon) agonism studies
• Metabolic regulation and energy homeostasis research
• Adipose tissue biology and lipid mobilization models
• Insulin sensitivity and pancreatic beta-cell research
• Appetite-regulating neuropeptide pathway studies
• Cardiovascular and hepatic metabolic research models

Research Applications

Retatrutide attracts the most scientific attention for its unique triple-receptor mechanism. Where GLP-1 agonists such as semaglutide activate only one receptor, Retatrutide simultaneously engages three receptors each playing a distinct role in energy metabolism. This makes it an exceptionally valuable research peptide for studies into the combined role of GIP, GLP-1, and glucagon in metabolic regulation.
