Histrelin
Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.
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 Histrelin and Triptorelin?
- Histrelin is classified as "Ricerca (altro)", while Triptorelin is classified as "Ricerca (altro)". Histrelin: Histrelin is a nonapeptide GnRH agonist delivered as a once-yearly implant. Approved for central precocious puberty in children (Supprelin LA) and advanced prostate cancer (Vantas). 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, Histrelin or Triptorelin?
- The highest available evidence level is "RCT sull'uomo" for Histrelin and "RCT sull'uomo" 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 Histrelin and Triptorelin in Germany and the United States?
- Germania: Histrelin — Su prescrizione, Triptorelin — Su prescrizione. Stati Uniti: Histrelin — Su prescrizione, Triptorelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
