DSIP

DSIP, also published as Delta Sleep-Inducing Peptide, is catalogued here as: Nonapeptide neuropeptide. DSIP expands to Delta Sleep-Inducing Peptide, a nine-amino-acid neuropeptide name. The name itself does not establish an effect on human sleep. A small peptide named Delta Sleep-Inducing Peptide. Its connection to sleep research is the starting point; specific findings are still under review.

A reviewed evidence summary for DSIP is still in progress, so this page does not summarize study findings yet.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people. The reconstitution calculator converts vial content and diluent volume into concentration for laboratory preparation.
