The concentration guide helps select appropriate products

Confusingly, both are marketed to researchers under the umbrella of IGF-1 variants, and the naming overlap has fostered a persistent misconception that they are interchangeable or that they work by the same route

By binding to GLP-1 receptors in the hypothalamus, they reduce appetite and promote satiety, leading to significant weight reduction in clinical trialswith newer agents achieving approximately 15% weight loss in obesity without diabetes (semaglutide) and up to 21% (tirzepatide), with somewhat lower reductions typically seen in patients with type 2 diabetes
