Buserelin
Buserelin is a potent GnRH agonist: after an initial stimulatory surge ('flare'), continuous receptor occupancy causes downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
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 Buserelin and Humanin?
- Buserelin is classified as "Onderzoek (overig)", while Humanin is classified as "Onderzoek (overig)". Buserelin: Buserelin is a synthetic GnRH agonist (including as a nasal spray). It is used in endometriosis, hormone-dependent prostate cancer and assisted reproduction; approved in Europe (Suprefact), not in the US. 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, Buserelin or Humanin?
- The highest available evidence level is "Humane RCT" for Buserelin 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 Buserelin and Humanin in Germany and the United States?
- Duitsland: Buserelin — Op recept, Humanin — Niet goedgekeurd. Verenigde Staten: Buserelin — Niet goedgekeurd, Humanin — Alleen onderzoek. These are factual summaries with source and review date on the individual pages.
