Efinopegdutide
Efinopegdutide is an oxyntomodulin-derived peptide acting as a dual agonist at the GLP-1 and glucagon receptors with a relative potency of approximately 2:1 (GLP-1 to glucagon). The GLP-1 component mediates glucose-dependent insulin secretion and modulation of satiety; the glucagon component increases energy expenditure and hepatic fat oxidation, which is proposed to contribute to the observed reduction in liver fat. Conjugation to an IgG4 fragment prolongs the half-life and enables weekly administration.
Lixisenatide
Lixisenatide is a 44-amino-acid peptide based on exendin-4 (see exenatide) with six additional lysine residues at the C-terminus. This modification increases stability against DPP-4 degradation. The short half-life (~3 hours) and plasma peak around mealtime explain the predominantly prandial effect — stronger postprandial glucose action, weaker fasting glucose effect than weekly GLP-1 RAs.

Frequently asked questions
- What is the difference between Efinopegdutide and Lixisenatide?
- Efinopegdutide is classified as "Metabool", while Lixisenatide is classified as "Metabool". Efinopegdutide: Efinopegdutide (MK-6024, formerly JNJ-64565111 / HM12525A) is a once-weekly dual agonist at the GLP-1 and glucagon receptors, developed by Hanmi and Merck. It has been studied for obesity and notably for metabolic liver disease (MASH/NAFLD); a phase-2 trial showed greater liver-fat reduction than semaglutide. Investigational, not approved. Lixisenatide: Synthetic exendin-4 analog with a C-terminal lysine extension. Prandial GLP-1 RA focused on postprandial glucose. FDA-approved 2016 as Adlyxin; EMA-approved 2013 as Lyxumia. Sanofi discontinued US distribution in 2023. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Efinopegdutide or Lixisenatide?
- The highest available evidence level is "Humane RCT" for Efinopegdutide and "Humane RCT" for Lixisenatide. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Efinopegdutide and Lixisenatide in Germany and the United States?
- Duitsland: Efinopegdutide — Niet goedgekeurd, Lixisenatide — Op recept. Verenigde Staten: Efinopegdutide — Niet goedgekeurd, Lixisenatide — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
