# Longevity Peptides

Peptides researched in the context of aging and lifespan extension.

### Epithalon

Low Evidence 

A tetrapeptide studied for its potential to activate telomerase and influence biological aging markers.

### Humanin

Low Evidence 

An endogenous mitochondrial-derived peptide studied for neuroprotection, cellular stress resistance, and longevity, whose blood levels fall with age and are elevated in centenarians.

### Klotho (Alpha-Klotho)

Low Evidence 

A naturally occurring longevity hormone (secreted alpha-klotho) being studied for cognition and brain aging; a single low-dose injection improved memory in aged monkeys, and a first-in-human Phase 1 trial in older adults is underway.

### SS-31

High Evidence 

A mitochondria-targeted peptide FDA-approved as FORZINITY (elamipretide) for Barth syndrome in September 2025 — the first FDA-approved mitochondrial-targeted therapeutic.
