MOTS-c vs Spermidine

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

Anti-Aging & Longevity
MOTS-c
Anti-Aging & LongevityCognitive Enhancement
Spermidine
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.'
Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
Half-Life
Estimated 1–2 hours
~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
Admin Route
SubQ
Oral
Research
Typical Dose
5–15 mg
1–5 mg
Frequency
3–5 times per week
Once daily
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
  • Induces autophagy — cellular self-cleaning
  • Extends lifespan in yeast, flies, worms, and mice
  • Reduces cardiovascular aging and arterial stiffness
  • Reduces all-cause mortality (human epidemiological data)
  • Neuroprotective: reduces amyloid and tau pathology
  • Promotes hair growth (anagen phase activation)
  • Reduces age-related immune decline
  • Improves memory in aging models
Side Effects
  • Injection site irritation
  • Fatigue during initial adaptation
  • Unknown long-term profile (limited human data)
  • Generally very well tolerated
  • Rare: mild GI discomfort at high doses
  • May temporarily reduce some gut bacteria species
  • Rare: headache at initiation
