Met-Glu-His-Phe-Pro-Gly-ProWerkingsmechanisme
Pasireotid
Pasireotide binds more broadly than older somatostatin analogs (SSTR1/2/3/5) with particularly high affinity for SSTR5. This suppresses, among others, ACTH release in Cushing's disease and GH release in acromegaly.
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 Pasireotid and Semax?
- Pasireotid is classified as "Onderzoek (overig)", while Semax is classified as "Onderzoek (overig)". Pasireotid: Pasireotide is a multireceptor somatostatin analog binding to four of the five somatostatin receptors (especially SSTR5). It is approved for Cushing's disease and acromegaly. 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, Pasireotid or Semax?
- The highest available evidence level is "Humane RCT" for Pasireotid 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 Pasireotid and Semax in Germany and the United States?
- Duitsland: Pasireotid — Op recept, Semax — Niet goedgekeurd. Verenigde Staten: Pasireotid — Op recept, Semax — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
