Last reviewed: April 28, 2026

A nonapeptide (9 amino acids) first isolated from rabbit cerebral venous blood in 1977. Originally studied for sleep-induction properties, it is now being investigated for opioid withdrawal and chronic insomnia.

Mechanism of Action

Modulates the sleep-wake cycle through interactions with opioid, serotonin, and other neurotransmitter systems. Reduces the activity of stress-response systems. Mechanism is not fully characterized, but effects appear to be on circadian regulation and stress adaptation.

Common Uses

  • Sleep quality improvement
  • Opioid withdrawal support
  • Stress and cortisol reduction
  • Chronic insomnia
  • Narcolepsy (investigational)

Known Risks

  • Limited human clinical data
  • Mechanism not fully understood
  • Potential interactions with opioid medications
  • Inconsistent results across studies
  • Long-term effects unknown
