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.
Tirzepatide
Tirzepatide is a 39-amino-acid peptide acting as a dual agonist at the GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors. Activation of both incretin receptors via G-protein-coupled signalling raises insulin secretion in a glucose-dependent manner, lowers glucagon secretion and delays gastric emptying. Centrally, satiety perception is modulated. A fatty-acid side chain binds to serum albumin and extends the half-life to about five days.

Frequently asked questions
- What is the difference between Petrelintide and Tirzepatide?
- Petrelintide is classified as "Метаболизм", while Tirzepatide is classified as "Метаболизм". 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. Tirzepatide: Synthetic peptide that simultaneously activates the GLP-1 and GIP receptor (dual agonist). Approved in the US and EU for type 2 diabetes (Mounjaro) and obesity (Zepbound). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Petrelintide or Tirzepatide?
- The highest available evidence level is "РКИ на людях" for Petrelintide and "РКИ на людях" for Tirzepatide. 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 Tirzepatide in Germany and the United States?
- Германия: Petrelintide — Не одобрено, Tirzepatide — Рецептурный. США: Petrelintide — Не одобрено, Tirzepatide — Рецептурный. These are factual summaries with source and review date on the individual pages.
