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.
Pasireotid
Pasireotide binds more broadly than older somatostatin analogs (SSTR1/2/3/5) with particularly high affinity for SSTR5. This suppresses, among others, ACTH release in Cushing's disease and GH release in acromegaly.

Frequently asked questions
- What is the difference between Nafarelin and Pasireotid?
- Nafarelin is classified as "Research other", while Pasireotid 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. Pasireotid: Pasireotide is a multireceptor somatostatin analog binding to four of the five somatostatin receptors (especially SSTR5). It is approved for Cushing's disease and acromegaly. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Nafarelin or Pasireotid?
- The highest available evidence level is "Human RCT" for Nafarelin and "Human RCT" for Pasireotid. 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 Pasireotid in Germany and the United States?
- Germany: Nafarelin — Prescription, Pasireotid — Prescription. United States: Nafarelin — Prescription, Pasireotid — Prescription. These are factual summaries with source and review date on the individual pages.
