Epitalon
Postulated mechanisms include modulation of gene expression in pinealocytes, telomerase activation (observed in cell culture studies) and influence on melatonin synthesis. A defined primary receptor is not established; the mechanistic basis rests on in-vitro and animal data from the Khavinson group.
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.

Frequently asked questions
- What is the difference between Epitalon and Kisspeptin-10?
- Epitalon is classified as "Ricerca (altro)", while Kisspeptin-10 is classified as "Ricerca (altro)". Epitalon: Synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the pineal extract epithalamin (V. Khavinson, St. Petersburg). Investigated in the Russian research and anti-ageing context; Western controlled trials are largely absent. No medicines approval in EU or US. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Epitalon or Kisspeptin-10?
- The highest available evidence level is "Studio sull'uomo" for Epitalon and "RCT sull'uomo" for Kisspeptin-10. 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 Epitalon and Kisspeptin-10 in Germany and the United States?
- Germania: Epitalon — Non approvato, Kisspeptin-10 — Non approvato. Stati Uniti: Epitalon — Non approvato, Kisspeptin-10 — Solo ricerca. These are factual summaries with source and review date on the individual pages.
