Ganirelix
Ganirelix competitively and reversibly binds the pituitary GnRH receptor, rapidly suppressing LH (and, less so, FSH) release — without the initial hormone 'flare' of GnRH agonists.
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 Ganirelix and Humanin?
- Ganirelix is classified as "Исследования (прочее)", while Humanin is classified as "Исследования (прочее)". Ganirelix: Ganirelix is a synthetic decapeptide and GnRH antagonist. In assisted reproduction (IVF) it prevents the premature LH surge during controlled ovarian stimulation. 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, Ganirelix or Humanin?
- The highest available evidence level is "РКИ на людях" for Ganirelix and "Исследование на людях" 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 Ganirelix and Humanin in Germany and the United States?
- Германия: Ganirelix — Рецептурный, Humanin — Не одобрено. США: Ganirelix — Рецептурный, Humanin — Только для исследований. These are factual summaries with source and review date on the individual pages.
