synthetisches Oxyntomodulin-Analogon (39 Aminosäuren) mit FettsäureseitenketteMechanism of action
Amycretin
Amycretin activates both the GLP-1 and the amylin receptor in a single molecule. Both pathways independently suppress appetite and food intake — the combination is intended to amplify the effect beyond the GLP-1 axis alone.
Mazdutide
Mazdutide is a dual agonist at the GLP-1 and glucagon receptors and is structurally derived from the gut hormone oxyntomodulin. The GLP-1 component mediates glucose-dependent insulin secretion, inhibition of glucagon secretion at elevated blood glucose, and modulation of appetite and gastric emptying. The glucagon component can influence energy expenditure and hepatic lipid and glucose metabolism. A fatty-acid side chain enables albumin binding and the weekly administration interval.

Frequently asked questions
- What is the difference between Amycretin and Mazdutide?
- Amycretin is classified as "Metabolic", while Mazdutide is classified as "Metabolic". Amycretin: Amycretin is a unimolecular GLP-1 and amylin receptor agonist from Novo Nordisk — in development both as a once-weekly subcutaneous and a once-daily oral form for obesity and type 2 diabetes. Mazdutide: Synthetic oxyntomodulin analogue that simultaneously activates the GLP-1 and glucagon receptors (dual agonist). Developed by Innovent Biologics and Eli Lilly. In China the NMPA approved mazdutide on 27 June 2025 for chronic weight management; a further filing for type 2 diabetes is under review in China. Outside China the substance remains in clinical development. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Amycretin or Mazdutide?
- The highest available evidence level is "Human RCT" for Amycretin and "Human RCT" for Mazdutide. 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 Amycretin and Mazdutide in Germany and the United States?
- Germany: Amycretin — Unapproved, Mazdutide — Research only. United States: Amycretin — Unapproved, Mazdutide — Research only. These are factual summaries with source and review date on the individual pages.
