DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide studied for its interaction with hypothalamic neuromodulatory signaling — historically named for its association with delta-wave (deep) sleep in research models.
DSIP is studied in the context of sleep architecture, stress-response modulation, and neuroendocrine signaling. As with most research peptides, the human evidence is limited and it's sold for laboratory use only.
Cognitive/calming peptides like Selank are sometimes discussed adjacent to sleep for their anxiolytic profile, though their primary research focus differs.
DSIP ships lyophilized — see how to reconstitute peptides and peptide storage.
DSIP is usually sold in 5 mg vials. PepsTracker compares it across 26 vendors on cost-per-mg. Platinum Peptides carries DSIP, 15% off with pepstracker15.
