SS-31 (Elamipretide) vs KPV

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

SS-31 (Elamipretide)
Immune SupportRecovery & Repair
KPV
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.
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.
Half-Life
~2–5 hours
Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
Admin Route

500 mcg – 1 mg
Frequency
Daily to several times per week
Once to twice daily
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
  • 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
Side Effects
  • Injection site irritation
  • Nausea (rare)
  • Generally well-tolerated in clinical trials
  • Generally very well tolerated
