Meccanismo d'azione
Kisspeptin-10
Kisspeptin-10 comprises the ten C-terminal amino acids sufficient for binding to the KISS1R receptor (also GPR54). KISS1R is a G-protein-coupled receptor expressed predominantly on GnRH neurons in the hypothalamus. Activation signals through the Gq/11-phospholipase C pathway to release gonadotropin-releasing hormone (GnRH), which in turn drives the pituitary to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Kisspeptin signaling is regarded as an indispensable trigger of puberty; inactivating mutations in KISS1R are associated with absent puberty (idiopathic hypogonadotropic hypogonadism). Beyond the reproductive axis, KISS1R expression is described in limbic brain regions, discussed as a possible mechanism for the effects on sexual and emotional processing observed in imaging studies.
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.

Frequently asked questions
- What is the difference between Kisspeptin-10 and Sekretin?
- Kisspeptin-10 is classified as "Ricerca (altro)", while Sekretin is classified as "Ricerca (altro)". Kisspeptin-10: Kisspeptin-10 is the shortest bioactive fragment (10 amino acids) of the endogenous neuropeptide kisspeptin, encoded by the KISS1 gene. It acts as an agonist at the KISS1R (GPR54) receptor and stimulates hypothalamic GnRH neurons, driving release of LH and FSH. Kisspeptin is a master switch of puberty and reproduction and is studied in humans, notably by the group of Waljit Dhillo (Imperial College London), in reproductive disorders and in sexual and emotional brain processing. It is not an approved drug. 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). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Kisspeptin-10 or Sekretin?
- The highest available evidence level is "RCT sull'uomo" for Kisspeptin-10 and "Studio sull'uomo" for Sekretin. 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 Kisspeptin-10 and Sekretin in Germany and the United States?
- Germania: Kisspeptin-10 — Non approvato, Sekretin — Su prescrizione. Stati Uniti: Kisspeptin-10 — Solo ricerca, Sekretin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
