FGL vs SS-31 (Elamipretide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
FGL
FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.
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 | FGL | SS-31 (Elamipretide) |
|---|---|---|
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | 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 | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. | 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 | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Limited human data available. Animal studies show good tolerability. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
