Mechanism of Action
Acts on sleep neurochemistry and circadian rhythm. Influences GABA and serotonin signaling pathways. Modulates neuroendocrine function and cortisol regulation.
Clinical Use
Sleep optimization, circadian rhythm support. Integrative medicine. No approved indication.
Contraindications
Depression (may alter serotonin dynamics). Epilepsy. Caution with other sedatives.
Evidence Summary
Human studies from 1980s-90s with small sample sizes showing sleep quality improvement. No modern large-scale RCTs.
Key Studies

Evidence Gaps
Very limited modern clinical data. Studies from 1980s-90s with small sample sizes. No large-scale RCTs ever conducted.
Emerging Research
Renewed interest in peptide-based sleep optimization. Opioid withdrawal applications revisited.
