Leuphasyl vs SS-31 (Elamipretide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
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 | Leuphasyl | SS-31 (Elamipretide) |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | 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: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | 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 to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
