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.
Retatrutide
Retatrutide is a 39-amino-acid peptide with agonism at three incretin/energy-balance receptors: GLP-1R (insulin secretion, satiety), GIPR (insulin sensitivity, lipid metabolism) and the glucagon receptor (energy expenditure, lipolysis). The added glucagon activation is intended to raise catabolic energy expenditure while concurrent GLP-1/GIP action compensates the hyperglycaemic effect. Albumin binding via a fatty-acid side chain enables weekly dosing.

Frequently asked questions
- What is the difference between Petrelintide and Retatrutide?
- Petrelintide is classified as "Metabolico", while Retatrutide is classified as "Metabolico". 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. Retatrutide: Synthetic triagonist peptide that simultaneously activates the GLP-1, GIP and glucagon receptors. Developed by Eli Lilly; in phase-3 trials for obesity (TRIUMPH programme) and type 2 diabetes. 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 Retatrutide?
- The highest available evidence level is "RCT sull'uomo" for Petrelintide and "RCT sull'uomo" for Retatrutide. 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 Retatrutide in Germany and the United States?
- Germania: Petrelintide — Non approvato, Retatrutide — Non approvato. Stati Uniti: Petrelintide — Non approvato, Retatrutide — Non approvato. These are factual summaries with source and review date on the individual pages.
