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.
Enfuvirtid
Enfuvirtide binds the first heptad-repeat region (HR1) of the gp41 subunit of the HIV envelope protein. This prevents the conformational change required for fusion of the viral and cell membranes — the virus cannot enter the cell.

Frequently asked questions
- What is the difference between Cetrorelix and Enfuvirtid?
- Cetrorelix is classified as "Research other", while Enfuvirtid 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. Enfuvirtid: Enfuvirtide is a synthetic 36-amino-acid peptide and the first HIV-1 fusion inhibitor. It binds the HR1 region of the viral envelope protein gp41, blocking viral entry into the cell. Approved for treatment-experienced HIV patients. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cetrorelix or Enfuvirtid?
- The highest available evidence level is "Human RCT" for Cetrorelix and "Human RCT" for Enfuvirtid. 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 Enfuvirtid in Germany and the United States?
- Germany: Cetrorelix — Prescription, Enfuvirtid — Prescription. United States: Cetrorelix — Prescription, Enfuvirtid — Prescription. These are factual summaries with source and review date on the individual pages.
