What is Humanin?

A 24-amino-acid mitochondrial-derived peptide encoded in the MOTS-C gene and expressed in mitochondria. Functions as a neuroprotectant and metabolic regulator, supporting neuronal survival, insulin sensitivity, and mitochondrial function.

How it works

Humanin binds to the humanin receptor and activates pro-survival PI3K and MAPK pathways in neurons. It also supports ATP production and mitochondrial biogenesis.

Background & history

Identified in 2001 from supercentenarians' mitochondrial DNA. Initially studied for neurodegenerative disease neuroprotection; later investigated for metabolic aging.

What the research says

Preclinical studies (mostly in mice and cell culture) demonstrate humanin protects neurons against apoptosis and may improve insulin sensitivity and metabolic function. Some small human observational studies are emerging, but rigorous clinical trial data are absent. Mechanism is mechanistically sound but clinical translation is incomplete. Evidence for human efficacy remains speculative.

Reported effects

Dosing & administration (informational)

Mouse studies used 1-10 micrograms/kg; human dosing entirely unknown. No clinical dose-escalation studies conducted.

This is general research/context information, not medical advice or a recommended protocol.

Safety & side effects

Drug & supplement interactions

Who should avoid it

How it is commonly combined

Humanin combined with other mitochondrial-supportive or neuroprotective peptides is theoretical; no human safety data.

Legal & regulatory. Not FDA-approved for human use. Investigational peptide for age-related diseases and neuroprotection. Available for research purposes only. Not a dietary supplement or approved drug.

Quality & harm reduction

Lab testing & harm-reduction tools

If you are going to research a compound, verifying identity and purity is the single most protective step. Independent analytical testing and sterile-handling supplies reduce risk.

Frequently asked questions

Is Humanin approved for human use?

No. Humanin is an investigational peptide with no approved human clinical use. It is available for research only.

What is the difference between Humanin and MOTS-C?

Both are mitochondrial-derived peptides with similar functions. Humanin is a 24-amino-acid peptide; MOTS-C is distinct. Both appear to support metabolic and neuroprotective functions.

Can Humanin reverse aging?

There is no human evidence that humanin reverses aging. Preclinical studies show promise for metabolic and neuronal support, but translation to humans is speculative.

How is Humanin administered?

As a peptide, Humanin would require injection for systemic effects. Oral administration would not work due to digestion.

Is Humanin naturally produced in my body?

Yes. Humanin is encoded in mitochondrial DNA and produced at low levels. Restoration of declining levels is the therapeutic hypothesis, unproven in humans.
