humanin
Humanin is a 24-amino acid mitochondrial-derived peptide (MDP) that acts as a potent cytoprotective and neuroprotective factor. It works by inhibiting apoptosis through interactions with Bax and Bcl-2 proteins and by reducing oxidative stress and inflammation across multiple organ systems.
Lab Notes — Research Studies
01 Humanin Prevents Age-Related Cognitive Decline in Mice and is Associated with Improved Cognitive Age in Humans
This study found that humanin administration improves memory in aged mice and that higher naturally occurring levels in humans are associated with better cognitive aging.

⚗️ Effects
- Cognition: Highly effective at preserving memory and learning capabilities in aging populations
- Longevity: Strongly correlated with healthspan extension and preserved mitochondrial function
- Cardiovascular: Shows significant promise in protecting vascular endothelium and preventing atherosclerosis
- Animal Models: Exceptional results in rodents, though human clinical trial data for direct supplementation is still emerging
💉 Dosage & Administration
- HNG Analog: The potent derivative HNG is often preferred in research settings due to its 1000-fold higher activity than natural Humanin
- Frequency: Research protocols often utilize twice-weekly administration for healthspan maintenance
- Administration: Typically administered via subcutaneous injection in experimental settings for optimal bioavailability
- Biological Markers: Circulating levels naturally decline with age, making 'replacement' levels a target for longevity enthusiasts
⚠️ Side Effects
- Minimal Risks: Humanin is an endogenous peptide, and studies generally report an excellent safety profile with few side effects
- Injection Site Irritation: As with most peptide injections, localized redness or soreness may occur
- Potential Growth Interaction: High levels are found in centenarians, but its interaction with growth hormone pathways requires careful monitoring
- Theoretical Concerns: Long-term effects of chronic supra-physiological levels in humans remain largely unstudied
📦 Availability & Sourcing
- Research Chemicals: Primarily available through peptide supply companies for laboratory and research use
- Endogenous Boosting: Lifestyle factors like exercise and cold exposure are sometimes discussed as natural ways to support Humanin levels
- Regulatory Status: Not currently FDA-approved for human medical treatment, strictly classified as a research compound
