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.
Humanin
Humanin arises from a short open reading frame within the 16S rRNA region of the mitochondrial genome (MT-RNR2) — it is therefore not encoded by nuclear DNA. Mechanistically, preclinical work describes a cytoprotective, anti-apoptotic effect via multiple pathways: an extracellular interaction with a trimeric receptor complex of gp130, CNTFR and WSX-1 with downstream activation of JAK2/STAT3 signalling, as well as intracellular interactions including inhibition of the pro-apoptotic protein BAX (and of tBID), binding to IGFBP-3 with modulation of the IGF-1 axis, and interaction with FPRL1/FPRL2 receptors. These models derive predominantly from cell culture and rodents; the extent to which they reflect human physiology after administration of exogenous synthetic humanin is not established by controlled human trials.

Frequently asked questions
- What is the difference between Elamipretide and Humanin?
- Elamipretide is classified as "Onderzoek (overig)", while Humanin is classified as "Onderzoek (overig)". 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. Humanin: Humanin is a 24-amino-acid mitochondrial-encoded peptide (mitochondrial-derived peptide, MDP) whose open reading frame lies within the 16S rRNA region (gene MT-RNR2) of mitochondrial DNA. It is considered the founding member of the MDP family and was discovered in 2001 by the Hashimoto/Nishimoto group while searching for neuroprotective factors in the brain of an Alzheimer's patient. In basic research (including the laboratory of Pinchas Cohen) humanin is described as a cytoprotective, anti-apoptotic peptide and is studied in the contexts of Alzheimer's/neuroprotection, metabolism/insulin action and aging. The evidence comes almost entirely from cell and animal models and from observations of endogenous levels in humans; controlled human trials of exogenous humanin as a therapeutic are lacking. It is not approved as a medicine anywhere and is traded on the grey market as a research chemical. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Elamipretide or Humanin?
- The highest available evidence level is "Humane RCT" for Elamipretide and "Humane studie" for Humanin. 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 Elamipretide and Humanin in Germany and the United States?
- Duitsland: Elamipretide — Niet goedgekeurd, Humanin — Niet goedgekeurd. Verenigde Staten: Elamipretide — Op recept, Humanin — Alleen onderzoek. These are factual summaries with source and review date on the individual pages.
