What is DSIP? DSIP (Delta Sleep-Inducing Peptide) is a nine-amino-acid neuropeptide originally isolated in 1977 from the cerebral venous blood of rabbits during induced slow-wave sleep. It has been studied in laboratory models for its associations with delta-wave EEG activity, circadian regulation,...
