FGL vs DSIP
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 →DSIP
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
Full details →Side-by-Side Comparison
| Aspect | FGL | DSIP |
|---|---|---|
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. |
| Typical Dosage | Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established. | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. |
| Administration | Subcutaneous injection or intranasal administration. Research compound with limited human dosing data. | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. |
| Side Effects | Limited human data available. Animal studies show good tolerability. | May cause grogginess upon waking, vivid dreams, or temporary headaches. |
