Mechanism of action
Cetrorelix
Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.
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 Cetrorelix and Pasireotid?
- Cetrorelix is classified as "Research other", while Pasireotid is classified as "Research other". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. 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, Cetrorelix or Pasireotid?
- The highest available evidence level is "Human RCT" for Cetrorelix 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 Cetrorelix and Pasireotid in Germany and the United States?
- Germany: Cetrorelix — Prescription, Pasireotid — Prescription. United States: Cetrorelix — Prescription, Pasireotid — Prescription. These are factual summaries with source and review date on the individual pages.
