DSIP
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
Mechanism of Action
Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties.
Dosage Overview
Dose Range
100 mcg – 300 mcg
Route
subcutaneous
Frequency
1x daily
Cycle Length
1–6 weeks
Reconstitution
Typical Dosage (Research)
Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically.
Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.
Considerations for Men & Women
Women: Delta sleep-inducing peptide may affect sleep architecture differently between sexes — women naturally have more slow-wave sleep. No established hormonal interactions. Avoid during pregnancy due to insufficient safety data.
Men: Same sleep-promoting research interest. Men may notice more pronounced slow-wave sleep improvement. No sex-specific dose adjustments.
Individual responses vary. These notes reflect general trends from research literature and are not medical advice.
