Introduction

GLP-3 research represents one of the newest and fastest-growing areas in metabolic science. Scientists are investigating compounds known as triple agonists, which are designed to activate three different hormone receptors involved in energy regulation and metabolism.

Unlike earlier compounds that target one or two receptors, GLP-3 research explores how combining multiple biological pathways may influence cellular signaling, energy balance, and metabolic function.

One of the most widely studied investigational compounds in this area is Retatrutide, which has become the focus of numerous laboratory and clinical research studies.

What Does GLP-3 Mean?

The term GLP-3 is commonly used to describe triple agonist research compounds that activate three hormone receptors involved in metabolic regulation:

GLP-1 (Glucagon-Like Peptide-1) Receptor
GIP (Glucose-Dependent Insulinotropic Polypeptide) Receptor
Glucagon Receptor

Researchers investigate how simultaneous activation of these receptors influences biological processes related to metabolism and energy regulation.
