Mechanism of action
Buserelin
Buserelin is a potent GnRH agonist: after an initial stimulatory surge ('flare'), continuous receptor occupancy causes downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
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 Buserelin and Enfuvirtid?
- Buserelin is classified as "Research other", while Enfuvirtid is classified as "Research other". Buserelin: Buserelin is a synthetic GnRH agonist (including as a nasal spray). It is used in endometriosis, hormone-dependent prostate cancer and assisted reproduction; approved in Europe (Suprefact), not in the US. 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, Buserelin or Enfuvirtid?
- The highest available evidence level is "Human RCT" for Buserelin 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 Buserelin and Enfuvirtid in Germany and the United States?
- Germany: Buserelin — Prescription, Enfuvirtid — Prescription. United States: Buserelin — Unapproved, Enfuvirtid — Prescription. These are factual summaries with source and review date on the individual pages.
