Description

Retatrutide is a research peptide studied for its activity at three metabolic signaling receptors: GLP-1, GIP and glucagon. It is used in laboratory work to compare single, dual and triple receptor activity in metabolic research models. Supplied as a lyophilized powder, strictly for laboratory research and analytical use.

Intended use · In-vitro laboratory research only. Not for human or animal consumption, and not for clinical, diagnostic, cosmetic or personal use.

N° 002 · How It Works

How Retatrutide works.

Retatrutide acts on three hormone receptors at once: GLP-1, GIP and glucagon. Researchers call this a triple agonist, to separate it from compounds that hit only one or two of those targets. GLP-1 and GIP are incretin receptors, involved in insulin release and appetite signalling. The glucagon receptor adds a third pathway, tied to how the liver and fat tissue use energy. A fatty acid chain on the molecule makes it last longer. It was first described in a 2022 paper in Cell Metabolism, and its metabolic effects were measured in two phase 2 trials in 2023.
