FGL vs Pinealon
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 →Pinealon
Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies.
Full details →Side-by-Side Comparison
| Aspect | FGL | Pinealon |
|---|---|---|
| Dose Range | 500 mcg–1 mg | 5 mg–10 mg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 4–8 weeks | 1–2 weeks |
| Route | intranasal | subcutaneous |
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | Penetrates cell membranes and interacts with DNA to regulate gene expression related to neuronal survival and function. May support pineal gland function and melatonin production. |
| Typical Dosage | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. | Typical dosing: 10-20mg daily, taken in divided doses. Often used in cycles of 10-20 days. |
| Administration | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. | Can be taken orally (capsules) or sublingually. Best absorbed on an empty stomach. Often combined with other neuroprotective peptides. |
| Side Effects | Limited human data available. Animal studies show good tolerability. | Generally well-tolerated. Limited reported side effects. May affect sleep patterns initially. |
