Reta 15 is a research-grade peptide that engages three metabolic hormone pathways: GLP-1, GIP, and glucagon. This multi-agonist mechanism offers a promising foundation for the exploration of advanced metabolic therapies, particularly in relation to obesity and type 2 diabetes.

By targeting these three receptors, Reta 15 has shown in early research models the potential to reduce appetite, enhance insulin sensitivity, and increase resting energy expenditure.

The product is supplied in a freeze-dried form to ensure maximum stability and purity throughout its shelf life.
