Petrelintide
As an amylin analogue, petrelintide acts through amylin receptors, promoting satiety and slowed gastric emptying — a satiety pathway independent of the GLP-1 axis.
Survodutide
Survodutide is a dual agonist at the GLP-1 and glucagon receptors. The GLP-1 component mediates glucose-dependent insulin secretion, inhibition of glucagon secretion at high blood glucose and modulation of satiety. The glucagon component raises basal energy expenditure via hepatic and brown adipocyte effects. A fatty-acid side chain enables albumin binding and weekly dosing.

Frequently asked questions
- What is the difference between Petrelintide and Survodutide?
- Petrelintide is classified as "Metabolic", while Survodutide is classified as "Metabolic". Petrelintide: Petrelintide is a long-acting amylin analogue (Zealand Pharma, with Roche) for once-weekly subcutaneous use — developed for weight management with a focus on strong tolerability. Survodutide: Synthetic peptide that simultaneously activates the GLP-1 and glucagon receptors. Developed by Boehringer Ingelheim and Zealand Pharma; in phase-3 trials for obesity (SYNCHRONIZE) and MASH. No marketing approval yet. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Petrelintide or Survodutide?
- The highest available evidence level is "Human RCT" for Petrelintide and "Human RCT" for Survodutide. 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 Petrelintide and Survodutide in Germany and the United States?
- Germany: Petrelintide — Unapproved, Survodutide — Unapproved. United States: Petrelintide — Unapproved, Survodutide — Unapproved. These are factual summaries with source and review date on the individual pages.
