- Mitochondrial-Derived Peptides (MOTS-c, Humanin)
- Activates PGC-1α and AMPK to drive biogenesis
- Nuclear gene transcription
- Rodent models show 30–65% metabolic improvements; human trials ongoing
- Effects persist 2–4 weeks post-administration
- Strongest mechanistic foundation. Directly encoded by mitochondrial genome
- SS Peptides (SS-31/Elamipretide)
- Stabilises cardiolipin to preserve cristae structure
- Inner membrane integrity
- Phase 2 human trials show 10–15% functional gains in mitochondrial disease patients
- Structural protection requires continued dosing
- Only class with completed human clinical trials for primary mitochondrial disorders
- Growth Hormone Secretagogues
- Elevates IGF-1 to enhance mitophagy and organelle turnover
- mTOR/AMPK signaling
- Indirect effects documented in longevity and metabolic studies; no mitochondria-specific trials
- Returns to baseline within 2–4 weeks of stopping
- Works through systemic hormonal shifts. Not mitochondria-specific but validated for metabolic health
- Thymic Peptides (Thymalin)
- Modulates immune cell mitochondrial dynamics
- T-cell energy metabolism
- Immunosenescence trials show extended lymphocyte lifespan
- Immune effects documented for 3–6 months
- Niche application. Relevant for immune aging, not general mitochondrial function
