Meccanismo d'azione

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.

Terlipressin

Terlipressin is slowly converted in the body to lysine-vasopressin by cleavage of the three N-terminal glycyl residues (reservoir effect) and activates V1 receptors. The splanchnic vasoconstriction improves renal perfusion in hepatorenal syndrome.

Frequently asked questions

What is the difference between Semax and Terlipressin?: Semax is classified as "Ricerca (altro)", while Terlipressin is classified as "Ricerca (altro)". 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. Terlipressin: Terlipressin is a 12-amino-acid vasopressin analog and prodrug of lysine-vasopressin. As a V1 receptor agonist it is vasoconstrictive and is approved for hepatorenal syndrome (FDA 2022, Terlivaz). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Semax or Terlipressin?: The highest available evidence level is "Studio sull'uomo" for Semax and "RCT sull'uomo" for Terlipressin. 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 Semax and Terlipressin in Germany and the United States?: Germania: Semax — Non approvato, Terlipressin — Su prescrizione. Stati Uniti: Semax — Non approvato, Terlipressin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
