Werkingsmechanisme

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.

Vasopressin

Vasopressin binds V1 receptors (vasoconstriction, raising vascular resistance) and V2 receptors (renal water reabsorption via aquaporin channels). This raises blood pressure and acts antidiuretically. Desmopressin is the V2-selective synthetic analog.

Frequently asked questions

What is the difference between Selank and Vasopressin?: Selank is classified as "Onderzoek (overig)", while Vasopressin is classified as "Onderzoek (overig)". 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. Vasopressin: Vasopressin (arginine vasopressin, antidiuretic hormone/ADH) is a cyclic nonapeptide hormone that regulates water balance and vascular tone. As Vasostrict it is approved to raise blood pressure in vasodilatory shock. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Selank or Vasopressin?: The highest available evidence level is "Humane studie" for Selank and "Humane RCT" for Vasopressin. 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 Selank and Vasopressin in Germany and the United States?: Duitsland: Selank — Niet goedgekeurd, Vasopressin — Op recept. Verenigde Staten: Selank — Niet goedgekeurd, Vasopressin — Op recept. These are factual summaries with source and review date on the individual pages.
