DSIP Delta Sleep-Inducing Peptide

For in vitro research use only. DSIP is not for human or veterinary consumption, diagnosis, treatment, or prevention of any condition.

DSIP is a short neuropeptide (a type of small protein used for signalling between brain cells) made up of just 9 amino acids. It was first isolated from rabbit blood during deep sleep. Animal studies have investigated how it interacts with the structure of sleep — particularly the deep, slow-wave stages — and how it affects the body's stress-response systems.

Research overview

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide — a small protein that carries signals between brain cells — consisting of just 9 amino acids (the building blocks of proteins). It was first isolated from the blood of rabbits observed during deep sleep states. Animal studies have investigated its effects on sleep architecture, particularly slow-wave and delta sleep stages (the deepest phases of sleep, associated with physical recovery and memory). Research has also looked at how it interacts with the body's stress-response axis — the hormonal system that controls how the body reacts to stress. Researchers study DSIP as a naturally occurring signal that may be involved in sleep regulation and hormonal balance. For research use only. Not for human or veterinary consumption.
