DSIP
Delta Sleep-Inducing Peptide
Delta Sleep-Inducing Peptide (DSIP) is a nonapeptide first isolated from the cerebral venous blood of rabbits in a state of naturally occurring sleep. Research has examined its roles in sleep stage modulation, stress axis regulation, and nociception. For research use only — not for human consumption.
Third-Party Tested. Every Lot.
Every batch of DSIP undergoes independent HPLC and mass spectrometry analysis through an accredited third-party laboratory before it is released for sale. No exceptions. No internal-only certificates.
RP-HPLC Analysis
Every lot measured by reverse-phase HPLC. DSIP consistently achieves 99.0%+ purity across batches.
ESI Mass Spec
Electrospray ionization mass spectrometry confirms exact molecular weight and rules out structural isomers or impurities.
Lot-Specific CoA
Your Certificate of Analysis references your exact lot number with actual chromatogram data — not a generic template.
Theoretical Research Analysis
All research information below reflects published preclinical literature only. This product is not for human use, consumption, or clinical application of any kind.
DSIP research has evolved from sleep-promoting characterization into a broader neuroendocrine role. Studies document dose-dependent effects on slow-wave sleep architecture and pituitary hormone secretion.
