Meccanismo d'azione

Histrelin

Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.

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 Histrelin and Semax?: Histrelin is classified as "Ricerca (altro)", while Semax is classified as "Ricerca (altro)". Histrelin: Histrelin is a nonapeptide GnRH agonist delivered as a once-yearly implant. Approved for central precocious puberty in children (Supprelin LA) and advanced prostate cancer (Vantas). 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, Histrelin or Semax?: The highest available evidence level is "RCT sull'uomo" for Histrelin and "Studio sull'uomo" 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 Histrelin and Semax in Germany and the United States?: Germania: Histrelin — Su prescrizione, Semax — Non approvato. Stati Uniti: Histrelin — Su prescrizione, Semax — Non approvato. These are factual summaries with source and review date on the individual pages.
