Mechanism of action
Nafarelin
Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
Teduglutid
Teduglutide activates the GLP-2 receptor, promoting growth and regeneration of small-intestinal villi, increasing nutrient and fluid absorption and thereby reducing dependence on parenteral nutrition. The glycine substitution at position 2 makes it resistant to rapid breakdown by DPP-4.

Frequently asked questions
- What is the difference between Nafarelin and Teduglutid?
- Nafarelin is classified as "Research other", while Teduglutid is classified as "Research other". Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. Teduglutid: Teduglutide is a DPP-4-resistant analog of GLP-2 (glucagon-like peptide-2). It promotes growth and function of the intestinal mucosa and is approved for treating short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Nafarelin or Teduglutid?
- The highest available evidence level is "Human RCT" for Nafarelin and "Human RCT" for Teduglutid. 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 Nafarelin and Teduglutid in Germany and the United States?
- Germany: Nafarelin — Prescription, Teduglutid — Prescription. United States: Nafarelin — Prescription, Teduglutid — Prescription. These are factual summaries with source and review date on the individual pages.
