About This Compound

DSIP (delta sleep-inducing peptide) is a nonapeptide first isolated from rabbit cerebral venous blood during induced sleep. Research has examined its effect on delta-wave sleep architecture, and separately its interaction with stress-response and neuroendocrine systems.

Naturally occurring nonapeptide first isolated from rabbit brain in 1977.
