Side-by-Side Comparison

AspectSelankSS-31 (Elamipretide)
MechanismModulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties.Concentrates in the inner mitochondrial membrane where it binds to cardiolipin, stabilizing electron transport chain function, reducing reactive oxygen species, and improving ATP production efficiency.
Typical DosageIntranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily.Clinical trials have used IV infusions of 0.25mg/kg for acute conditions. Subcutaneous dosing protocols for research use typically range from 1-5mg daily.
AdministrationMost commonly administered intranasally for cognitive effects. Can also be injected subcutaneously.Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions.
Side EffectsGenerally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use.Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache.
