What it is

The first mitochondrial-derived peptide (MDP) ever discovered, encoded within the MT-RNR2 gene (16S rRNA region) of the mitochondrial genome. Humanin was identified in 2001 through functional expression screening of a cDNA library from the surviving occipital lobe of an Alzheimer's disease patient. It operates through both intracellular mechanisms (binding pro-apoptotic BAX and tBID to block intrinsic apoptosis, sequestering IGFBP-3) and extracellular receptor-mediated signaling (CNTFR/WSX-1/gp130 trimeric receptor activating JAK2/STAT3, and FPRL1/FPR2 activating ERK1/2).

Studied in animal models across neurodegenerative, cardiovascular, metabolic, and retinal disease contexts. The S14G-Humanin (HNG) analog is approximately 1,000-fold more potent. No completed human clinical trials exist for this compound.

Published research

Humanin was independently discovered by three labs in 2001 — the Hashimoto/Nishimoto group (neuroprotection from Alzheimer's-related insults), the Reed lab (BAX binding), and the Cohen lab (IGFBP-3 interaction). Preclinical research spans neuroprotection against amyloid-beta and all tested familial AD mutants, cardiovascular protection (atherosclerosis, ischemia-reperfusion), central and peripheral insulin sensitization (Muzumdar et al., PLoS ONE 2009), retinal protection (AMD models), and aging biology (endogenous levels decline with age).

Pharmacokinetic studies in rodents show species-dependent half-life (~30 min mice, ~4 hours rats) with IGFBP-3 binding influencing clearance. No peer-reviewed human clinical trials have been completed as of March 2026. Dosing ranges used in community settings are extrapolated from animal data and are not clinically validated.

What the terms on this page mean9 terms
peptide
A short chain of amino acids, the building blocks of proteins.
receptor
A docking point on a cell. A molecule that fits it can switch a process on or off inside that cell.
animal model
A test in animals standing in for the human condition. Results often fail to carry over to people.
analog
A molecule built to copy a natural one with a deliberate change, usually to make it last longer or bind more tightly.
clinical trial
A study that tests something in people under a written plan, with results recorded.
preclinical
Laboratory and animal work done before any testing in people.
endogenous
Made by the body itself, rather than given from outside.
pharmacokinetics
How fast the body absorbs a substance, where it goes, and how it clears it out.
half-life
The time it takes for a drug's concentration in the blood to fall by half. It does not, by itself, determine a dosing schedule.

Compounding status

Not on either FDA list
FDA listing
Humanin appears on neither FDA's category 2 table nor its table of withdrawn nominations.
What that means
Absence from both lists is not permission to compound. Section 503A allows a bulk drug substance only where a USP or NF monograph exists, or the substance is a component of an FDA-approved drug product, or it appears on the 503A bulks list.

About this page

Reviewed 2026-08-11. This page reports what published studies and FDA documents say. It carries no dose, cycle length or stack, and it does not tell you whether a substance is appropriate for you. Side-effect reports circulating on forums are self-reported rather than measured, so they are not republished here.
