Eloralintide
Eloralintide selectively activates amylin receptors (preferentially AMY1R) and promotes satiety. The approach targets weight loss via the amylin axis, complementary to or independent of GLP-1 agents.
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 Eloralintide and Tirzepatide?
- Eloralintide is classified as "Metabolic", while Tirzepatide is classified as "Metabolic". Eloralintide: Eloralintide is a selective, long-acting amylin receptor agonist from Eli Lilly for once-weekly subcutaneous use — under investigation for obesity, alone and combined with incretin therapy. 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, Eloralintide or Tirzepatide?
- The highest available evidence level is "Human RCT" for Eloralintide and "Human RCT" 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 Eloralintide and Tirzepatide in Germany and the United States?
- Germany: Eloralintide — Unapproved, Tirzepatide — Prescription. United States: Eloralintide — Unapproved, Tirzepatide — Prescription. These are factual summaries with source and review date on the individual pages.
