About DSIP and Sleep Research

Sleep research tracks how the brain moves between sleep stages, usually by recording its electrical activity. Deep, slow-wave sleep appears as delta waves, which is where delta sleep-inducing peptide gets its name.

DSIP was isolated in the 1970s from the blood of rabbits in an electrically induced state of sleep. Later animal studies tested whether it changes sleep patterns, with inconsistent results, and its natural source and receptor are still unknown. Each product in this category is supplied for controlled laboratory research and educational investigation only.
