DSIP is a nonapeptide historically studied in EEG delta-wave and sleep-research animal models. Full Kiwi Peps DSIP peptide research profile inside.
The DSIP peptide (Delta Sleep-Inducing Peptide) is a synthetic nonapeptide originally isolated from rabbit cerebral venous blood during EEG delta-wave induction studies. Its endogenous receptor remains debated in the published literature — most references treat DSIP as a neuromodulator rather than a classical receptor agonist. It has an extensive Eastern-European and Russian-language research history in sleep and neuroendocrine animal models.

DSIP peptide FAQ
What is the DSIP peptide?
DSIP is a synthetic 9-residue peptide (WAGGDASGE) originally isolated from rabbit cerebral venous blood in EEG delta-wave induction studies, cited as a neuromodulator in published sleep-research literature.
Does DSIP have a defined receptor?
The endogenous receptor remains debated in published literature. Most references treat DSIP as a modulator rather than a classical receptor agonist.
Where can New Zealand researchers buy DSIP?
Kiwi Peps supplies DSIP at ≥98% HPLC purity with third-party COA and same-day domestic dispatch. Research use only.
