About the research

Retatrutide is a 39-amino-acid linear synthetic peptide developed as the first triple agonist of GLP-1, GIP, and glucagon receptors. The fatty-acid linker enables albumin binding and a ~6-day plasma half-life. It represents one of the most extensively studied next-generation incretin compounds in metabolic research.

Mechanism, reported research areas, literature dose ranges and co-factor studies are on the research page, with sources. Nothing there is a claim about this product.
