DSIP

Delta Sleep-Inducing Peptide

Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu

human trialanimal study

A neuropeptide originally isolated from rabbit brain cerebral venous blood during induced sleep. DSIP modulates sleep architecture, stress responses, and pain perception. Despite its name, it doesn't directly induce sleep but rather normalises sleep patterns and improves sleep quality.

Modulates GABAergic and glutamatergic neurotransmission, affects hypothalamic-pituitary-adrenal axis to reduce cortisol, and influences serotonin and dopamine pathways. Promotes slow-wave (delta) sleep without sedation.

  • Sleep quality
  • Stress reduction
  • Pain management
  • Withdrawal support
  • Circadian rhythm regulation
  • · Mild headache
  • · Transient hypotension
  • · Morning grogginess (rare)
