SS-31 (Elamipretide) vs Noopept

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

Anti-Aging & Longevity
SS-31 (Elamipretide)
Cognitive Enhancement
Noopept
Summary
SS-31 (Elamipretide) is a synthetic mitochondria-targeting tetrapeptide that concentrates in the inner mitochondrial membrane and protects cardiolipin from oxidative damage. It is one of the most promising mitochondrial longevity compounds, studied in clinical trials for heart failure, renal disease, and age-associated mitochondrial dysfunction.
Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.

Key Benefits
  • Restores mitochondrial function and ATP production
  • Protects inner mitochondrial membrane cardiolipin
  • Reduces mitochondrial reactive oxygen species (ROS)
  • Improves exercise capacity and reduces fatigue
  • Cardioprotective — studied in heart failure trials
  • Renoprotective — reduces ischemic kidney injury
  • Anti-aging via mitochondrial preservation
  • Potential in neurodegenerative disease prevention
  • Enhances memory formation and recall
  • Improves learning speed and cognitive processing
  • Neuroprotective via BDNF/NGF upregulation
  • Anxiolytic at low-to-moderate doses
  • Improves verbal fluency and information processing
  • Antioxidant (reduces oxidative damage in neurons)
  • May improve cognitive symptoms of mild cognitive impairment
Side Effects
  • Injection site irritation
  • Nausea (rare)
  • Generally well-tolerated in clinical trials
  • Headaches (choline depletion — pair with choline source)
  • Irritability or anxiety at high doses
  • Overstimulation
  • Rare: brain fog with chronic use
