DSIP
Also known as: Delta Sleep-Inducing Peptide
DSIP (Delta Sleep-Inducing Peptide) is a 9-amino-acid neuropeptide first isolated from the cerebral venous blood of sleeping rabbits. As its name suggests, it promotes the delta-wave (deep, restorative) phase of sleep and has additional effects on stress reduction, pain modulation, and hormonal balance. Used by individuals with sleep disturbances, jet lag, or chronic stress.

Half-Life
~30 minutes (but effects on sleep persist longer)
Common Dose
100–300 mcg per night
Route
Subcutaneous injection
Frequency
Once daily
Mechanism of Action
The exact mechanism is not fully understood, but DSIP appears to modulate GABAergic activity, influence circadian rhythm regulation, reduce cortisol secretion, and increase delta-wave EEG activity during sleep. It also has analgesic and stress-buffering effects via interaction with the HPA axis.
