Goserelin
As a GnRH agonist, goserelin binds to the GnRH receptors of the pituitary gland. Initial stimulation transiently raises luteinizing hormone (LH) and follicle-stimulating hormone (FSH). With continuous receptor occupancy, however, the receptors become desensitized and down-regulated, which reduces LH and FSH secretion and consequently the production of testosterone or estrogen. This mechanistic relationship is documented in the pharmacological literature.
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 Goserelin and Octreotide?
- Goserelin is classified as "Исследования (прочее)", while Octreotide is classified as "Исследования (прочее)". Goserelin: Goserelin is a synthetic decapeptide and an agonist of gonadotropin-releasing hormone (GnRH). The medical literature describes it as a hormonal agent that suppresses the release of sex hormones through sustained receptor stimulation. Regulatory-approved indications include prostate cancer, advanced breast cancer, endometriosis, and endometrial thinning, among others. 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, Goserelin or Octreotide?
- The highest available evidence level is "РКИ на людях" for Goserelin 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 Goserelin and Octreotide in Germany and the United States?
- Германия: Goserelin — Рецептурный, Octreotide — Рецептурный. США: Goserelin — Рецептурный, Octreotide — Рецептурный. These are factual summaries with source and review date on the individual pages.
