Werkingsmechanisme

Sekretin

Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

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 Sekretin and Semax?: Sekretin is classified as "Onderzoek (overig)", while Semax is classified as "Onderzoek (overig)". Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). 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, Sekretin or Semax?: The highest available evidence level is "Humane studie" for Sekretin 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 Sekretin and Semax in Germany and the United States?: Duitsland: Sekretin — Op recept, Semax — Niet goedgekeurd. Verenigde Staten: Sekretin — Op recept, Semax — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
