Research Background

First isolated from rabbit cerebral venous blood in 1977, DSIP is an amphiphilic peptide capable of crossing the blood-brain barrier. It is distinctive because it does not act as a sedative but rather modulates the sleep-wake cycle towards restorative slow-wave sleep. Beyond sleep, it is extensively researched for its antioxidant properties and its ability to normalize hormonal responses to acute stress.
