DSIP
Also known as: Delta sleep-inducing peptide
A brain peptide named for its link to delta waves, the slow brain waves that show up during the deepest stage of sleep.
- Full name
- Delta sleep-inducing peptide
- Type
- Brain peptide
- Category
- Sleep & restoration
- FDA status
- Not FDA-approved
Overview
What it is
DSIP stands for delta sleep-inducing peptide. Researchers first found it in brain tissue while studying how sleep is controlled, and named it for the slow delta waves seen in deep sleep.
DSIP was found in 1974, in blood taken from rabbits whose brains were being stimulated into sleep. Researchers named it for the slow delta waves they were seeing.
The name promised more than the research delivered. Human studies in the 1980s were small and gave mixed results, and interest largely faded.
It has never been established where DSIP comes from in the body or what its natural job is, which is unusual for a peptide this well known by name.
Benefits
What it supports
- Supports deep, restful sleep and a steadier sleep cycle
- Supports a calmer stress response through the body's main stress-hormone system
- Supports recovery from fatigue and heavy training loads
- Supports rest-and-restore goals alongside brain-focused peptides such as pinealon
Mechanism
How it works
1
Sleep runs in stages. Deep sleep, the stage tied to physical recovery, shows up on a brain recording as slow delta waves.
2
DSIP was named for its apparent link to that stage, though how it would produce the effect has never been pinned down.
3
It has also been studied in relation to the body's main stress-hormone system, the loop running from the brain to the adrenal glands. Stress and sleep are closely tied, so that connection is plausible.
4
The honest summary is that the biology is unsettled. It is named after an effect that later studies struggled to reproduce.

Regulatory & considerations
DSIP is not FDA-approved. That means the FDA has not reviewed it for safety or effectiveness for the uses described here. Human sleep studies are few, old, and small, so its effects are not well established.
Peptides in our shop are sourced from US-licensed manufacturers.
DSIP is not FDA-approved, and the human studies behind it are few, small, and decades old.
Poor sleep has many causes, and some of them are treatable conditions like sleep apnea. Those are worth ruling out before anything else.
The name describes what researchers hoped it did. Later studies had trouble confirming it.
