Research brief · Cognitive
DSIP
Nonapeptide studied in sleep, stress and circadian research models.
Class
Nonapeptide
Half-life
~7 min (systemic)
Studied in
Sleep architecture, stress and circadian research models.
What it is
DSIP is a naturally occurring nonapeptide originally isolated from rabbit cerebral venous blood. Research focuses on delta-wave EEG modulation, stress-axis effects and circadian biology.
Mechanism studied
Modulates EEG delta-wave activity and stress-response peptide release.
Research notes
- Very short systemic half-life — typically delivered as a research tool compound.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
