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.
Gonadorelin
Gonadorelin acts as an agonist at the GnRH receptor on the gonadotroph cells of the pituitary and triggers release of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The temporal pattern of receptor exposure is decisive: pulsatile administration mimics the natural hypothalamic secretory rhythm and sustains LH/FSH release, whereas continuous exposure leads to receptor internalisation and desensitisation with subsequent paradoxical suppression of gonadotropins. The latter principle is exploited therapeutically by longer-acting GnRH agonists.

Frequently asked questions
- What is the difference between Desmopressin and Gonadorelin?
- Desmopressin is classified as "Ricerca (altro)", while Gonadorelin is classified as "Ricerca (altro)". 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. Gonadorelin: Gonadorelin is the synthetic decapeptide with an amino-acid sequence identical to endogenous gonadotropin-releasing hormone (GnRH/LHRH). Historically approved in several countries for diagnostic testing of pituitary function and for fertility indications (pump systems). A defining feature is the opposite effect of pulsatile versus continuous administration: pulsatile stimulates, continuous leads to receptor desensitisation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Desmopressin or Gonadorelin?
- The highest available evidence level is "RCT sull'uomo" for Desmopressin and "Studio sull'uomo" for Gonadorelin. 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 Gonadorelin in Germany and the United States?
- Germania: Desmopressin — Su prescrizione, Gonadorelin — Su prescrizione. Stati Uniti: Desmopressin — Su prescrizione, Gonadorelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
