KPV vs SS-31 (Elamipretide)

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

SS-31 (Elamipretide)
Summary
KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
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.
Half-Life
Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
~2–5 hours

Key Benefits
  • Reduces intestinal inflammation (IBD, Crohn's, colitis)
  • Promotes gut mucosal healing and barrier integrity
  • Accelerates wound healing topically
  • Suppresses systemic inflammatory cytokines
  • Antimicrobial properties against pathogens
  • Reduces neuroinflammation when administered systemically
  • May improve symptoms of inflammatory skin conditions
  • 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
Side Effects
  • Generally very well tolerated
  • Mild injection site reactions (SC)
  • Rare: transient flushing
