MOTS-c vs Thymalin

Side-by-side comparison of key properties, dosing, and research.

Thymalin
Summary
MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
Thymalin is a polypeptide complex isolated from calf thymus glands (developed by the Russian Gerontology Institute), shown to restore immune function, extend lifespan, and reverse thymic involution. Clinical studies demonstrate improved immune parameters and up to 40% reduction in mortality in elderly patients.

Key Benefits
  • Improves insulin sensitivity and glucose metabolism
  • Enhances exercise capacity and endurance
  • Reduces age-related metabolic decline
  • Activates AMPK — the master metabolic regulator
  • Promotes fat oxidation
  • Anti-inflammatory effects
  • May extend healthspan via mitochondrial optimization
  • Increases energy and reduces fatigue
  • Restores thymic function and T-cell immunity
  • Extends healthy lifespan (documented in long-term studies)
  • Reduces infectious disease incidence in elderly
  • Normalizes immune parameters in immunodeficiency
  • Anti-tumor immune surveillance
  • Improves vaccine response in elderly
  • Reduces cardiovascular mortality (40% in landmark Russian study)
  • Normalizes neuroendocrine function
Side Effects
  • Injection site irritation
  • Fatigue during initial adaptation
  • Unknown long-term profile (limited human data)
  • Very well tolerated in decades of Russian clinical use
  • Mild injection site reactions
  • Rare: mild allergic reaction (natural extract)
  • Transient flu-like symptoms on initiation (immune activation)
