DSIP (Delta Sleep-Inducing Peptide) 10mg
Delta sleep-inducing peptide (DSIP) is a nonapeptide first isolated from the cerebral venous blood of rabbits during electrically induced sleep in 1977 by Schoenenberger and Monnier. Its sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. Its name reflects early rabbit EEG observations; the cited 2006 review describes its natural occurrence and biological activity as unresolved. Supplied strictly for in-vitro research and laboratory use only. Not for human or animal use.

Mechanism of Action
The precise receptor target of DSIP remains under investigation. Schoenenberger and Monnier reported enhanced delta and spindle EEG patterns after intraventricular infusion of synthetic DSIP in rabbits. Kovalzon and Strekalova's 2006 review describes the sleep-factor hypothesis as poorly documented and reports that DSIP itself did not promote slow-wave sleep in their cited rabbit and rat experiments.
