Carbetocin
Carbetocin is an oxytocin receptor agonist with prolonged duration. It triggers a sustained contraction of the uterus after birth, preventing atonic hemorrhage — unlike oxytocin, without a multi-hour infusion.
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 Carbetocin and Humanin?
- Carbetocin is classified as "Ricerca (altro)", while Humanin is classified as "Ricerca (altro)". Carbetocin: Carbetocin is a long-acting synthetic oxytocin analog (half-life ~40 minutes). It prevents postpartum hemorrhage as a single injection. Approved in Canada and the UK among others, 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, Carbetocin or Humanin?
- The highest available evidence level is "RCT sull'uomo" for Carbetocin and "Studio sull'uomo" 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 Carbetocin and Humanin in Germany and the United States?
- Germania: Carbetocin — Su prescrizione, Humanin — Non approvato. Stati Uniti: Carbetocin — Non approvato, Humanin — Solo ricerca. These are factual summaries with source and review date on the individual pages.
