Механизм действия

Nafarelin

Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to 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 Nafarelin and Selank?: Nafarelin is classified as "Исследования (прочее)", while Selank is classified as "Исследования (прочее)". Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. 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, Nafarelin or Selank?: The highest available evidence level is "РКИ на людях" for Nafarelin 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 Nafarelin and Selank in Germany and the United States?: Германия: Nafarelin — Рецептурный, Selank — Не одобрено. США: Nafarelin — Рецептурный, Selank — Не одобрено. These are factual summaries with source and review date on the individual pages.
