Histrelin
Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.
Octreotide
Octreotide is a cyclic octapeptide that selectively binds somatostatin-receptor subtypes SSTR2 and SSTR5. Via G-protein-coupled signalling, adenylyl cyclase is inhibited, reducing the secretion of multiple hormones (growth hormone, IGF-1, glucagon, insulin, VIP, serotonin). Structural stabilisation via a disulfide bridge and D-amino acids extends the half-life relative to natural somatostatin (minutes to several hours).

Frequently asked questions
- What is the difference between Histrelin and Octreotide?
- Histrelin is classified as "Исследования (прочее)", while Octreotide is classified as "Исследования (прочее)". 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). Octreotide: Synthetic octapeptide somatostatin analog with a longer half-life than endogenous somatostatin. FDA- and EMA-approved since the 1980s for acromegaly and neuroendocrine tumours. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Histrelin or Octreotide?
- The highest available evidence level is "РКИ на людях" for Histrelin and "РКИ на людях" for Octreotide. 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 Histrelin and Octreotide in Germany and the United States?
- Германия: Histrelin — Рецептурный, Octreotide — Рецептурный. США: Histrelin — Рецептурный, Octreotide — Рецептурный. These are factual summaries with source and review date on the individual pages.
