DSIP vs NA-Selank Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 →NA-Selank Amidate
NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.
Full details →Side-by-Side Comparison
| Aspect | DSIP | NA-Selank Amidate |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Same core mechanism as Selank - modulates BDNF, serotonin, and norepinephrine systems. The N-acetyl group improves membrane permeability while the amidate modification increases enzymatic stability. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. |
