Lanreotid
Lanreotide activates somatostatin receptors (chiefly SSTR2, additionally SSTR5), thereby suppressing the release of growth hormone, IGF-1 and various gastrointestinal and neuroendocrine hormones. It is metabolically far more stable than natural somatostatin.
Leuprorelin
Leuprorelin is a GnRH-receptor agonist. After binding to pituitary GnRH receptors, it first causes a transient surge in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release — the so-called flare. With continuous, non-pulsatile exposure the receptors are downregulated and desensitized, suppressing gonadotropin secretion and consequently lowering sex steroids (testosterone or estradiol) to low levels. This mechanism underlies the literature-described use in hormone-dependent conditions.

Frequently asked questions
- What is the difference between Lanreotid and Leuprorelin?
- Lanreotid is classified as "Исследования (прочее)", while Leuprorelin is classified as "Исследования (прочее)". Lanreotid: Lanreotide is a synthetic cyclic octapeptide analog of somatostatin. It binds preferentially to the somatostatin receptors SSTR2 and SSTR5 and is approved for treating acromegaly and certain neuroendocrine tumours. Leuprorelin: Leuprorelin (also leuprolide) is a synthetic nonapeptide analogue of gonadotropin-releasing hormone (GnRH/LHRH). It is an approved prescription medicine in several jurisdictions, including for advanced prostate cancer, endometriosis, uterine fibroids and central precocious puberty. This page neutrally summarizes the evidence base and legal status and is not a usage or dosing recommendation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Lanreotid or Leuprorelin?
- The highest available evidence level is "РКИ на людях" for Lanreotid and "РКИ на людях" for Leuprorelin. 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 Lanreotid and Leuprorelin in Germany and the United States?
- Германия: Lanreotid — Рецептурный, Leuprorelin — Рецептурный. США: Lanreotid — Рецептурный, Leuprorelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
