SNAP-8 vs SS-31 (Elamipretide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
SNAP-8
SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of wrinkles by modulating muscle contraction. It is often called 'topical Botox' though it works through a different mechanism.
Full details →SS-31 (Elamipretide)
SS-31, also known as Elamipretide or Bendavia, is a mitochondria-targeted tetrapeptide. It has been studied extensively for mitochondrial diseases, heart failure, and age-related decline in mitochondrial function.
Full details →Side-by-Side Comparison
| Aspect | SNAP-8 | SS-31 (Elamipretide) |
|---|---|---|
| Mechanism | Mimics the N-terminal end of SNAP-25, competing with native SNAP-25 for position in the SNARE complex. This reduces neurotransmitter release at the neuromuscular junction, decreasing muscle contraction. | 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 Dosage | Topical: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). | 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. |
| Administration | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
