Cetrorelix
Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.
Elamipretide
Elamipretide is a cell-permeable tetrapeptide with alternating aromatic and basic residues that selectively concentrates on cardiolipin — a phospholipid found almost exclusively in the inner mitochondrial membrane that is important for cristae curvature and the organisation of the respiratory-chain complexes. By binding cardiolipin, elamipretide is proposed to stabilise cristae architecture, support electron transport and ATP production, and reduce the formation of reactive oxygen species. These mechanistic models derive largely from cell and animal models and biophysical work; the extent to which they explain clinical efficacy in humans is, given the mixed trial results, a matter of ongoing research.

Frequently asked questions
- What is the difference between Cetrorelix and Elamipretide?
- Cetrorelix is classified as "Исследования (прочее)", while Elamipretide is classified as "Исследования (прочее)". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. Elamipretide: Elamipretide (SS-31, MTP-131, formerly Bendavia) is a synthetic, mitochondria-targeting tetrapeptide (sequence D-Arg-Dmt-Lys-Phe-NH2) that binds cardiolipin on the inner mitochondrial membrane and is proposed to stabilise cristae structure and support mitochondrial bioenergetics. It was investigated clinically by Stealth BioTherapeutics across several indications, including primary mitochondrial myopathy, Barth syndrome, heart failure, and dry age-related macular degeneration (geographic atrophy). The trial record is mixed, with several pivotal studies missing their primary endpoints. In September 2025 elamipretide (brand name Forzinity) received accelerated FDA approval in the United States solely for the ultra-rare Barth syndrome; for all other investigated indications it remains investigational and it is not approved as a medicine outside the United States. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cetrorelix or Elamipretide?
- The highest available evidence level is "РКИ на людях" for Cetrorelix and "РКИ на людях" for Elamipretide. 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 Cetrorelix and Elamipretide in Germany and the United States?
- Германия: Cetrorelix — Рецептурный, Elamipretide — Не одобрено. США: Cetrorelix — Рецептурный, Elamipretide — Рецептурный. These are factual summaries with source and review date on the individual pages.
