Naturally occurring nonapeptide first isolated in 1977. Characterized by delta-frequency EEG activity induction and studied for neuromodulatory properties across sleep regulation, stress response, and CNS signaling.
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated in 1977 by the research group of Dr. Marcel Monnier and Dr. Guido Schoenenberger at the University of Basel in Switzerland. The peptide was identified during electrophysiological experiments on rabbits in which cerebral venous blood from sleep-induced animals was infused into recipient subjects, where it produced a characteristic increase in delta-frequency electroencephalographic activity. DSIP has been studied in laboratory research for nearly five decades for its neuromodulatory properties, with documented investigation across sleep regulation, stress response, and central nervous system signaling.
Each vial contains 5 mg of DSIP supplied as a lyophilized white powder at ≥99% purity, with 10 vials per package. As a small nonapeptide, DSIP is highly soluble after reconstitution with bacteriostatic or sterile water. The compound is used in controlled laboratory settings investigating its broad-spectrum neuromodulatory effects.
