Glucagon
Glucagon is produced in the alpha cells of the pancreas (islets of Langerhans) and released when blood sugar is low. Glucagon binds the glucagon receptor (GCGR), a G-protein-coupled receptor expressed predominantly on hepatocytes. Activation stimulates adenylate cyclase, raises cyclic AMP and activates protein kinase A. This drives glycogenolysis (breakdown of hepatic glycogen into glucose) and gluconeogenesis (de novo glucose synthesis), which raises blood glucose. Glucagon also promotes lipolysis. As the counterpart to insulin it contributes to glucose homeostasis. It transiently relaxes gastrointestinal smooth muscle, which is the basis of its diagnostic use in imaging.
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 Glucagon and Tirzepatide?
- Glucagon is classified as "Метаболизм", while Tirzepatide is classified as "Метаболизм". Glucagon: Glucagon is a 29-amino-acid pancreatic hormone produced by the alpha cells of the islets of Langerhans. It is the physiological counterpart to insulin and raises blood glucose via hepatic glycogenolysis and gluconeogenesis. It is approved as an emergency treatment for severe hypoglycaemia and as a diagnostic aid; its receptor is also a target of modern dual and triple incretin agonists. 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, Glucagon or Tirzepatide?
- The highest available evidence level is "РКИ на людях" for Glucagon 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 Glucagon and Tirzepatide in Germany and the United States?
- Германия: Glucagon — Рецептурный, Tirzepatide — Рецептурный. США: Glucagon — Рецептурный, Tirzepatide — Рецептурный. These are factual summaries with source and review date on the individual pages.
