Mechanism of action
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.
Histrelin
Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.

Frequently asked questions
- What is the difference between Enfuvirtid and Histrelin?
- Enfuvirtid is classified as "Research other", while Histrelin is classified as "Research other". 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. Histrelin: Histrelin is a nonapeptide GnRH agonist delivered as a once-yearly implant. Approved for central precocious puberty in children (Supprelin LA) and advanced prostate cancer (Vantas). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Enfuvirtid or Histrelin?
- The highest available evidence level is "Human RCT" for Enfuvirtid and "Human RCT" for Histrelin. 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 Enfuvirtid and Histrelin in Germany and the United States?
- Germany: Enfuvirtid — Prescription, Histrelin — Prescription. United States: Enfuvirtid — Prescription, Histrelin — Prescription. These are factual summaries with source and review date on the individual pages.
