Retatrutide

Triple Receptor Agonist

Retatrutide is a triple receptor co-agonist acting at the GIP, GLP-1, and glucagon receptors, and one of the most-studied investigational peptides in current metabolic research. The addition of glucagon-receptor activity is the defining distinction from the dual agonist tirzepatide and single-receptor semaglutide.

In vitro and preclinical work focuses on multi-receptor pharmacodynamics, insulin and glucagon signaling balance, energy expenditure pathways, and lipid metabolism, with particular attention to how glucagon-receptor engagement contributes to the overall metabolic profile. Because it is investigational, retatrutide is studied strictly in research contexts rather than approved use. Supplied as a lyophilized 10-vial kit across 10mg to 60mg sizes for in vitro research use only.

Common Questions

Retatrutide FAQ

What is Retatrutide?+
Retatrutide is a Triple Receptor Agonist supplied for laboratory research. Triple GIP, GLP-1, and glucagon receptor co-agonist studied in preclinical research for multi-receptor pharmacodynamics, energy expenditure pathway modeling, and lipid metabolism analysis.
How is Retatrutide different from semaglutide and tirzepatide?+
Retatrutide is a triple receptor agonist acting on the GIP, GLP-1, and glucagon receptors, whereas semaglutide targets GLP-1 alone and tirzepatide targets GIP and GLP-1. This added glucagon-receptor activity is a key focus of current metabolic research.
What is lyophilized Retatrutide, and how is it reconstituted?+
Retatrutide is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should Retatrutide be stored?+
Store the lyophilized Retatrutide powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of Retatrutide, and how is it tested?+
Every batch of Retatrutide is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
