Glepaglutide
As a GLP-2 receptor agonist, glepaglutide has a trophic effect on the intestinal mucosa, enlarging the absorptive surface and thereby improving intestinal uptake of nutrients and fluid.
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 Glepaglutide and Kisspeptin-10?
- Glepaglutide is classified as "Research other", while Kisspeptin-10 is classified as "Research other". Glepaglutide: Glepaglutide is a long-acting GLP-2 analogue (Zealand Pharma) intended to reduce the need for parenteral support in short bowel syndrome. 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, Glepaglutide or Kisspeptin-10?
- The highest available evidence level is "Human RCT" for Glepaglutide and "Human RCT" 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 Glepaglutide and Kisspeptin-10 in Germany and the United States?
- Germany: Glepaglutide — Unapproved, Kisspeptin-10 — Unapproved. United States: Glepaglutide — Unapproved, Kisspeptin-10 — Research only. These are factual summaries with source and review date on the individual pages.
