FGL vs MOTS-c
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.

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.
Full details →Side-by-Side Comparison
| Aspect | FGL | MOTS-c |
|---|---|---|
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis. |
| Typical Dosage | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. |
| Administration | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. |
| Side Effects | Limited human data available. Animal studies show good tolerability. | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. |
