DSIP (Delta Sleep-Inducing Peptide)

Research profile · How we handle evidence

Delta Sleep-Inducing Peptide (DSIP). A naturally occurring neuropeptide originally pulled from rabbit brain back in 1977. Found in brain, pituitary, adrenal glands, and blood plasma. As the name suggests, it promotes slow-wave (delta) sleep - the deep restorative stuff. Also reduces stress hormones and has been researched for insomnia, pain management, and alcohol withdrawal.

Overview

DSIP is your body's natural sleep signal. It promotes deep delta sleep where most physical repair happens. Lowers cortisol and has mild pain-relieving properties. Used by researchers and biohackers for insomnia, stress, and improving sleep quality. Some report better mood and less anxiety. Not a sedative - you'll wake up feeling rested, not groggy.

pH & Mixing

3.6

Peptides reconstituted at very different pH levels can destabilize when combined in the same syringe, which lowers how much of the peptide your body actually absorbs. If you're unsure whether two peptides are close enough in pH, reconstitute and inject them separately.

A dedicated compatibility check between two specific peptides is coming to the Compare tool. This section covers this peptide's pH only.

Benefits

  • Promotes deep, restorative delta wave sleep
  • Reduces cortisol and stress hormones
  • Mild analgesic (pain-relieving) properties
  • May help with alcohol withdrawal symptoms
  • Non-sedating - improves sleep quality without morning grogginess
  • Potentially anti-tumor properties (limited evidence)

Side Effects

  • Generally well-tolerated
  • Mild dizziness in some users
  • Headache
  • Very short half-life limits duration of action

Contraindications

  • Pregnant or breastfeeding women
  • Individuals under 18 years old
  • Those with known allergies to peptide components
