Delta Sleep-Inducing Peptide
For educational and research purposes only. Not medical advice.
DSIP specifically promotes deep delta-wave sleep, the most restorative sleep phase. Studies show improved sleep architecture without next-day grogginess. Also shows stress-protective and analgesic properties. Limited but consistent clinical evidence.
Best Time
30-60 min before bed
Method
subcutaneous
Frequency
Before bed
Half-life
~15 minutes (but effects on sleep architecture last all night)
Cycle Length
2-4 weeks
Storage
Refrigerate at 2-8°C.
Published Dosing Ranges

DSIP promotes delta-wave sleep when GH secretion naturally peaks. Ipamorelin before bed amplifies the nocturnal GH pulse. Community-reported synergy for recovery and sleep quality.
communitySelank's anxiolytic GABA modulation combined with DSIP's delta-wave sleep promotion. Anxiety reduction during the day + restorative sleep at night for cognitive recovery.
communityDSIP is a sleep-promoting peptide; Semax is a stimulating nootropic. Not inherently conflicting — used at different times (Semax AM, DSIP PM) — but theoretical concern about opposing neurological effects.

Mechanism of Action
Modulates sleep architecture by promoting delta (deep) sleep stages. Acts on multiple systems including GABA, serotonin, and the hypothalamic-pituitary axis. Also has stress-protective and analgesic properties.
