Also known as: Delta Sleep-Inducing Peptide
DSIP (Delta Sleep-Inducing Peptide) is a small peptide made of 9 amino acids that acts in the brain. Scientists first found it in blood taken from the brains of sleeping rabbits. As its name says, it helps bring on deep, restful sleep (the delta-wave stage). It also affects stress, pain and hormone balance. People with sleep problems, jet lag or long-lasting stress use it.

In plain English
What does DSIP do?
DSIP is a small peptide studied for sleep. Research suggests it may help people fall asleep faster and get more deep, restful sleep.
What researchers study it for
- Deep sleep. It may boost the deep, restful stage of sleep.
- Falling asleep. It may shorten the time it takes to fall asleep.
- Jet lag and shift work. It is studied for helping the body adjust to new sleep times.
- Stress. It may lower cortisol, a stress hormone, and calm the body's stress response.
- Pain and mood. It may ease pain a little and may lift mood.
How it works, in everyday words
DSIP was first found in the blood of sleeping rabbits. No one knows exactly how it works yet. It seems to affect the brain's calming signals and the body clock that sets sleep times. It only stays in the body about 30 minutes, but its effect on sleep seems to last longer.
Good to know
- In studies it is injected under the skin once a day, about 30 minutes before bed.
- Its effects are subtle. They are easier to judge after 1 to 2 weeks of steady use.
- Decades of research include human studies. It is sold for research only and is not approved to treat people.

The Science Behind It
No one fully knows yet how DSIP works. It appears to affect GABA, a brain chemical that calms nerve cells. It may also help set the body clock (circadian rhythm). It seems to lower cortisol, a stress hormone. It also seems to boost deep-sleep brain waves (delta waves on an EEG test). It may ease pain and stress through its interaction with the HPA axis, the body's stress system.
