Humanin

Humanin (Peptide) Information



Humanin is a naturally occurring mitochondrial-derived peptide (MDP) composed of 24 amino acids. It is produced by mitochondria and has gained attention for its potential cytoprotective, neuroprotective, metabolic, and anti-aging properties. Research is ongoing, and most evidence comes from preclinical studies rather than large human clinical trials.



Potential Benefits



Brain & Nervous System



* May protect neurons from oxidative stress

* Investigated for potential roles in Alzheimer’s and other neurodegenerative diseases

* May support cognitive function and memory

* Helps reduce apoptosis (programmed cell death)



Metabolic Health



* May improve insulin sensitivity

* Supports healthy glucose metabolism

* Potential benefits in obesity and metabolic syndrome research



Cardiovascular Support



* May protect heart cells from ischemic injury

* Supports mitochondrial function

* May reduce oxidative damage in cardiovascular tissues



Healthy Aging



* Supports mitochondrial health

* May reduce cellular stress

* Investigated for longevity and age-related decline

* May help preserve cellular function over time



Muscle Recovery



* May help reduce oxidative stress after intense exercise

* Supports cellular energy production

* Potential role in improving recovery, though human data are limited



Mechanism of Action



Humanin interacts with several cellular signaling pathways involved in:



* Cell survival

* Anti-apoptotic activity

* Mitochondrial protection

* Reduction of oxidative stress

* Modulation of inflammatory signaling



Its primary role appears to be protecting cells from stress and maintaining mitochondrial function.



Suggested Clinical Administration



Humanin is generally administered by subcutaneous (SC) injection in research settings. Because it remains investigational, there is no standardized or approved dosing regimen for general clinical use.



Storage



* Store lyophilized peptide refrigerated (2–8°C / 36–46°F)

* After reconstitution, refrigerate

* Protect from light

* Avoid repeated freeze-thaw cycles



Possible Side Effects



Human data are limited, but reported or theoretical effects include:



* Injection site irritation

* Mild headache

* Temporary fatigue

* Nausea (uncommon)



Overall safety in long-term use has not been established.



Research Areas



Humanin is being investigated for:



* Alzheimer’s disease

* Parkinson’s disease

* Type 2 diabetes

* Cardiovascular disease

* Sarcopenia (age-related muscle loss)

* Healthy aging and longevity



Notes



* Humanin is not FDA-approved for anti-aging or performance enhancement.

* Most evidence comes from laboratory and animal studies, with limited human clinical research.

* It is considered an investigational peptide, and its long-term efficacy and safety remain under study.
