Desmopressin
Desmopressin is a structurally modified analogue of the nine-residue peptide hormone vasopressin. Deamination at the N-terminus (1-deamino) and replacement of L-arginine by D-arginine at position 8 prolong the duration of action and render the compound largely selective for the vasopressin V2 receptor, while the V1-mediated vasoconstrictive effect is strongly reduced. Acting on V2 receptors in the renal collecting ducts, it promotes insertion of aquaporin-2 water channels into the apical membrane, increasing water reabsorption and reducing urine volume (antidiuretic effect). In addition, via V2 receptors on the vascular endothelium, desmopressin stimulates the release of von Willebrand factor and factor VIII from endothelial stores (Weibel-Palade bodies), improving primary haemostasis.
Triptorelin
Triptorelin binds with high affinity to the GnRH receptor in the pituitary. After initial stimulation of LH and FSH secretion (flare phase, about 1-2 weeks), receptor desensitisation follows with consecutive gonadotropin suppression. This results in a reversible chemical castration: in men testosterone, in women oestrogen suppression to the postmenopausal range.

Frequently asked questions
- What is the difference between Desmopressin and Triptorelin?
- Desmopressin is classified as "Research other", while Triptorelin is classified as "Research other". Desmopressin: Desmopressin (DDAVP) is a synthetic analogue of the endogenous hormone vasopressin (antidiuretic hormone, ADH). Deamination of the first amino acid and substitution of L-arginine with D-arginine give it selective activity at the V2 receptor with strongly reduced pressor (V1) activity. It has been approved for decades for indications including central diabetes insipidus, primary nocturnal enuresis, and bleeding tendency in von Willebrand disease type 1 and mild haemophilia A. The principal safety concern is hyponatremia or water intoxication. Triptorelin: Synthetic decapeptide GnRH agonist with increased affinity over native gonadotropin-releasing hormone. FDA- and EMA-approved since the 1980s for prostate cancer, endometriosis and precocious puberty. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Desmopressin or Triptorelin?
- The highest available evidence level is "Human RCT" for Desmopressin and "Human RCT" for Triptorelin. 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 Desmopressin and Triptorelin in Germany and the United States?
- Germany: Desmopressin — Prescription, Triptorelin — Prescription. United States: Desmopressin — Prescription, Triptorelin — Prescription. These are factual summaries with source and review date on the individual pages.
