Linaclotid
Linaclotide activates the guanylate cyclase-C receptor on the luminal surface of the intestinal epithelium. This raises cyclic GMP (cGMP), increases secretion of chloride and bicarbonate into the lumen, raises stool fluid content and accelerates transit; pain signaling is also modulated.
Melanotan II
Melanotan II binds non-selectively to all five melanocortin-receptor subtypes (MC1R-MC5R). Via MC1R in melanocytes, eumelanin synthesis is stimulated (pigmenting effect). Via MC4R and MC3R in the CNS, appetite, sexual function and blood pressure are modulated. The cyclic structure and D-amino acids increase stability compared to natural α-MSH.

Frequently asked questions
- What is the difference between Linaclotid and Melanotan II?
- Linaclotid is classified as "Исследования (прочее)", while Melanotan II is classified as "Исследования (прочее)". Linaclotid: Linaclotide is a 14-amino-acid peptide and guanylate cyclase-C (GC-C) agonist. It is approved for irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). Melanotan II: Cyclic hepta-peptide and non-selective melanocortin-receptor agonist. Originally researched at the University of Arizona as a sun-protection concept — never approved as a medicine. Widespread on the black market; regulatory warnings for cardiovascular and oncological risks. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Linaclotid or Melanotan II?
- The highest available evidence level is "РКИ на людях" for Linaclotid and "Исследование на людях" for Melanotan II. 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 Linaclotid and Melanotan II in Germany and the United States?
- Германия: Linaclotid — Рецептурный, Melanotan II — Не одобрено. США: Linaclotid — Рецептурный, Melanotan II — Не одобрено. These are factual summaries with source and review date on the individual pages.
