DSIP — research data
Research-literature reference data, NOT patient instructions. Not for human use. Consult a licensed clinician for any human application.
Overview
About DSIP
Mechanism of action
Neuropeptide that crosses the blood-brain barrier; modulates GHRH, somatostatin, and LH secretion; reduces somatostatin activity; promotes slow-wave (delta) sleep.
Safety profile
Generally well-tolerated. Occasional headache, slight fatigue post-injection. Long-term data limited. · Benign profile: well-tolerated in human studies (incl. a 1991 double-blind insomnia trial), with no reported tolerance, dependence, or withdrawal. Endogenous nonapeptide; main limitation is thin/old data, not safety signals.

Studies & key findings
- Originally isolated from rabbit cerebral venous blood during slow-wave sleep (Monnier et al., 1977), DSIP is one of the first peptides identified as a sleep regulator.
- Beyond sleep induction, has demonstrated analgesic properties in chronic pain models, stress-protective effects, and benefit in alcohol and opiate withdrawal syndromes.
