DSIP 15 mg
Also known as · Delta Sleep-Inducing Peptide
DSIP was isolated from the cerebral venous blood of sleeping rabbits in the 1970s by the Monnier / Schoenenberger group. One of the earliest discovered neuroactive peptides.

Research context
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide first isolated from the cerebral venous blood of rabbits during electrically induced delta sleep. Despite the name, its role in sleep regulation has not been consistently replicated and its mechanism of action remains incompletely characterised.
Used predominantly in preclinical neurophysiology research.
