Setmelanotide
Setmelanotide is an agonist at the melanocortin-4 receptor (MC4R), a central receptor of the hypothalamic melanocortin pathway involved in the control of energy balance, satiety and body weight. In certain genetic defects (e.g. in POMC, PCSK1 or LEPR), the natural activation of MC4R is reduced. Setmelanotide activates MC4R directly, thereby bypassing the upstream defect. This description is mechanistic and neutral and does not constitute a recommendation for use.
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 Setmelanotide and Tirzepatide?
- Setmelanotide is classified as "Метаболизм", while Tirzepatide is classified as "Метаболизм". Setmelanotide: Setmelanotide (brand name Imcivree) is a synthetic cyclic octapeptide and an agonist at the melanocortin-4 receptor (MC4R). It was developed and approved as a prescription medicine for chronic weight management in rare genetic forms of obesity within the MC4R signalling pathway (including POMC, PCSK1 and LEPR deficiency as well as Bardet-Biedl syndrome). The following information is provided for informational and educational purposes only. 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, Setmelanotide or Tirzepatide?
- The highest available evidence level is "РКИ на людях" for Setmelanotide 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 Setmelanotide and Tirzepatide in Germany and the United States?
- Германия: Setmelanotide — Рецептурный, Tirzepatide — Рецептурный. США: Setmelanotide — Рецептурный, Tirzepatide — Рецептурный. These are factual summaries with source and review date on the individual pages.
