DSIP
Delta Sleep-Inducing Peptide
A neuropeptide designed to promote deep, restorative delta wave sleep.
DSIP is a naturally occurring nonapeptide found in the brain, hypothalamus, and pituitary gland. It was first isolated in the 1970s from rabbits in a state of deep sleep. Research focuses on its unique ability to modulate sleep architecture, particularly by increasing slow-wave (delta) sleep, which is critical for physical and mental restoration.
Key Benefits
Mechanism of Action
DSIP readily crosses the blood-brain barrier and exerts its effects by modulating various neurotransmitter systems. It influences serotonergic and GABAergic activity, both of which are central to sleep regulation. Its primary action is believed to be the promotion of delta wave activity in the brain's EEG, which corresponds to the deepest stage of non-REM sleep.
Dosing Guidelines
Typical Dose
25-100 mcg
Frequency
1x daily
Duration
4-8 weeks or as needed
Note: Administer via subcutaneous (SubQ) or intramuscular (IM) injection 30-60 minutes before bedtime. It is best to start at the low end of the dose range and titrate up to find the minimum effective dose.
