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.
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 Gonadorelin and Triptorelin?
- Gonadorelin is classified as "Исследования (прочее)", while Triptorelin is classified as "Исследования (прочее)". 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. 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, Gonadorelin or Triptorelin?
- The highest available evidence level is "Исследование на людях" for Gonadorelin and "РКИ на людях" 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 Gonadorelin and Triptorelin in Germany and the United States?
- Германия: Gonadorelin — Рецептурный, Triptorelin — Рецептурный. США: Gonadorelin — Рецептурный, Triptorelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
