Механизм действия

Cetrorelix

Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.

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 Cetrorelix and Selank?: Cetrorelix is classified as "Исследования (прочее)", while Selank is classified as "Исследования (прочее)". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. 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, Cetrorelix or Selank?: The highest available evidence level is "РКИ на людях" for Cetrorelix 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 Cetrorelix and Selank in Germany and the United States?: Германия: Cetrorelix — Рецептурный, Selank — Не одобрено. США: Cetrorelix — Рецептурный, Selank — Не одобрено. These are factual summaries with source and review date on the individual pages.
