| Aspect | DSIP (Delta Sleep-Inducing Peptide) | Semax |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Enhances BDNF expression, modulates dopamine and serotonin systems, and provides neuroprotective effects. Increases attention, memory formation, and learning. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Intranasal: 200-600mcg 2-3 times daily. Higher doses (up to 1mg) used in clinical settings for stroke recovery. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Primarily administered intranasally. N-Acetyl Semax Amidate (NASA) is a modified version with enhanced stability and potency. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Generally well-tolerated. May cause mild irritability or hair shedding in some users. |
