Retatrutide 6mg is a lyophilised research vial of the investigational triple-agonist peptide, available from Peptide Sciences for metabolic receptor research. The 6mg size is our introductory format for labs beginning work with this next-generation incretin.
Retatrutide: A Triple Receptor Agonist
Retatrutide (LY3437943) is a single peptide that activates three receptors: GIP, GLP-1 and glucagon. Adding glucagon-receptor agonism to the dual incretin approach is hypothesised to increase energy expenditure and hepatic fat oxidation in experimental models. Researchers use it to separate the metabolic contribution of glucagon signalling from that of GIP and GLP-1 alone, often running it alongside tirzepatide and semaglutide.

Getting Started with Retatrutide 6mg
The 6mg vial suits receptor-activation assays, signalling-bias studies and short pilot protocols. Once your methods are validated, the 12mg and 16mg vials provide the same specification in larger quantities.
Quality Control, COA and Shipping
Before any batch reaches the catalog it is tested for purity by HPLC and verified by mass spectrometry against its theoretical mass. A Certificate of Analysis accompanies each shipment, and all material is stored cold and protected from light until dispatch.
