Механизм действия

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.

Selank

Selank is a glyproline-tuftsin analog. Proposed mechanisms include modulation of the GABAergic system, effects on serotonin bioavailability, and influence on enkephalinases. Animal studies show anxiolytic and neuroprotective markers; a clear receptor target is not established.

Frequently asked questions

What is the difference between Buserelin and Selank?: Buserelin is classified as "Исследования (прочее)", while Selank is classified as "Исследования (прочее)". 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. Selank: Synthetic heptapeptide derived from natural tuftsin. Approved as an anxiolytic (Selank) in Russia and some CIS states. Western phase-3 trials are absent; efficacy assessment relies on Russian research literature. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Buserelin or Selank?: The highest available evidence level is "РКИ на людях" for Buserelin and "Исследование на людях" for Selank. 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 Selank in Germany and the United States?: Германия: Buserelin — Рецептурный, Selank — Не одобрено. США: Buserelin — Не одобрено, Selank — Не одобрено. These are factual summaries with source and review date on the individual pages.
