# Humanin

> Humanin is a short mitochondrial-derived peptide encoded within the mitochondrial 16S rRNA gene region, first identified through research on Alzheimer's-disease-resistant neurons. It has since been studied for broader roles in cellular stress resistance, metabolic regulation, and protection against oxidative damage. Research spans cell culture, animal models, and a smaller body of observational human studies correlating circulating humanin levels with age and disease states. It remains primarily a research compound, and synthetic humanin analogs used outside clinical trials are not regulated therapeutics.

## Mechanism of action

Humanin is proposed to bind cell-surface receptor complexes, including formyl peptide receptor-like 1, to activate intracellular survival signaling pathways such as STAT3 and AMPK. This signaling may help protect cells against apoptosis triggered by oxidative stress or beta-amyloid exposure. It has also been studied for potential roles in mitochondrial quality control and systemic metabolic regulation.

## Reported benefits

- Studied for potential neuroprotective effects against oxidative and beta-amyloid stress
- Explored for roles in mitochondrial and metabolic health
- May support cellular stress resistance in preclinical models
- Investigated as a biomarker and potential target in age-related research

## Reported side effects

- Limited human safety data
- Injection site irritation possible
- Theoretical concerns given its role in cell survival signaling and cancer biology
- Unknown long-term effects

## Common protocols

- Daily subcutaneous dosing in short research-style cycles

## Stacking notes

Sometimes discussed alongside other mitochondria-focused peptides such as SS-31; combination effects are not studied in humans
