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.
Terlipressin
Terlipressin is slowly converted in the body to lysine-vasopressin by cleavage of the three N-terminal glycyl residues (reservoir effect) and activates V1 receptors. The splanchnic vasoconstriction improves renal perfusion in hepatorenal syndrome.

Frequently asked questions
- What is the difference between Buserelin and Terlipressin?
- Buserelin is classified as "Research other", while Terlipressin 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. Terlipressin: Terlipressin is a 12-amino-acid vasopressin analog and prodrug of lysine-vasopressin. As a V1 receptor agonist it is vasoconstrictive and is approved for hepatorenal syndrome (FDA 2022, Terlivaz). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Buserelin or Terlipressin?
- The highest available evidence level is "Human RCT" for Buserelin and "Human RCT" for Terlipressin. 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 Terlipressin in Germany and the United States?
- Germany: Buserelin — Prescription, Terlipressin — Prescription. United States: Buserelin — Unapproved, Terlipressin — Prescription. These are factual summaries with source and review date on the individual pages.
