Peptides for Weight Loss: Tirzepatide, RT, and GLP — A Guide

The class of incretin peptides (GLP-1 and dual/triple agonists) is one of the hottest topics in metabolism and weight-management research. Let's break down the main molecules in plain language.

What GLP peptides are

These are analogues of natural hormones involved in the regulation of appetite, glucose levels, and the feeling of satiety. In research, they are studied in the context of metabolism, weight, and insulin sensitivity.

Tirzepatide

Tirzepatide is a dual agonist of the GIP and GLP-1 receptors. Thanks to this dual mechanism, it is being actively studied in the context of weight management and metabolic markers. Available in various dosages.

RT (GLP-3)

RT is a triple agonist (GIP/GLP-1/glucagon), one of the newest molecules in this class, studied as the next step after tirzepatide.

How to choose
