DSIPEmerging / mixed evidence

Delta sleep-inducing peptide

An endogenous neuropeptide first characterised for inducing delta-wave (slow-wave) sleep, researched for sleep, stress and pain modulation, with mixed results.

⚙️ How it works

Acts as a neuromodulator rather than a direct sedative, appearing to normalise dysregulated sleep-wake cycles and increase delta-wave EEG activity. Proposed NMDA-receptor involvement and MAPK interaction; widely distributed in the hypothalamus and limbic system. Its precise receptor remains poorly defined.

🎯 What it's studied to help

Sleep40/100
May normalise sleep-wake cycles and increase delta-wave sleep; one study showed improved efficiency, but results are inconsistent.
Broad neuromodulatory/stress activity suggested, but human evidence is preliminary.
Stress-normalising effects are theorised to support recovery, with very limited data.
