Werkingsmechanisme

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.

Semax

Semax is a tetracosactide fragment analog without hormonal activity at MC2R. Proposed mechanisms include elevation of BDNF and NGF in hippocampus and striatum (in animal models), modulation of dopamine metabolism, and neuroprotective effects via anti-apoptotic pathways. A clear primary receptor is not established.

Frequently asked questions

What is the difference between Nafarelin and Semax?: Nafarelin is classified as "Onderzoek (overig)", while Semax is classified as "Onderzoek (overig)". 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. Semax: Synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10). Approved in Russia for ischaemic stroke, cognitive function and ADHD in children. Western phase-3 trials absent. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Nafarelin or Semax?: The highest available evidence level is "Humane RCT" for Nafarelin and "Humane studie" for Semax. 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 Semax in Germany and the United States?: Duitsland: Nafarelin — Op recept, Semax — Niet goedgekeurd. Verenigde Staten: Nafarelin — Op recept, Semax — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
