The next generation after Ozempic, Wegovy and Mounjaro. Retatrutide is the first peptide to target THREE appetite-control pathways instead of one or two — and the published trials show the strongest body-composition effects in the class.

Who it's for: Researchers studying triple-pathway (GLP-1 + GIP + glucagon) metabolic peptides.

The science behind it

Retatrutide is a 39-amino-acid triagonist activating GLP-1R, GIP-R, and glucagon-R. Glucagon-receptor activation adds thermogenic energy expenditure on top of incretin appetite suppression. Phase 3 data published 2023-2024.
