Nafarelin
Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
Bremelanotide
Bremelanotide is a cyclic peptide that binds non-selectively to melanocortin receptors (MC1R through MC5R) — with highest affinity at MC4R in the central nervous system. The precise role of MC4R activation in sexual behaviour is not fully understood; animal data show effects on hypothalamic circuits. Peripheral effects (blood pressure, hyperpigmentation) are attributed to MC1R/MC2R.

Frequently asked questions
- What is the difference between Nafarelin and Bremelanotide?
- Nafarelin is classified as "Исследования (прочее)", while Bremelanotide is classified as "Исследования (прочее)". Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. Bremelanotide: Synthetic cyclic heptapeptide acting as a non-selective melanocortin-receptor agonist. FDA-approved in 2019 as Vyleesi for hypoactive sexual desire disorder (HSDD) in pre-menopausal women. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Nafarelin or Bremelanotide?
- The highest available evidence level is "РКИ на людях" for Nafarelin and "РКИ на людях" for Bremelanotide. 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 Nafarelin and Bremelanotide in Germany and the United States?
- Германия: Nafarelin — Рецептурный, Bremelanotide — Не одобрено. США: Nafarelin — Рецептурный, Bremelanotide — Рецептурный. These are factual summaries with source and review date on the individual pages.
