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.
Sekretin
Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

Frequently asked questions
- What is the difference between Buserelin and Sekretin?
- Buserelin is classified as "Research other", while Sekretin 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. Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Buserelin or Sekretin?
- The highest available evidence level is "Human RCT" for Buserelin and "Human trial" for Sekretin. 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 Sekretin in Germany and the United States?
- Germany: Buserelin — Prescription, Sekretin — Prescription. United States: Buserelin — Unapproved, Sekretin — Prescription. These are factual summaries with source and review date on the individual pages.
