Delta sleep-inducing peptide (DSIP) is a small peptide investigated historically in sleep, neuroendocrine and stress-related research. Reviews of the literature describe a broad range of experimental observations but also substantial uncertainty around its natural role and biological activity.
Research areas
Sleep-related neurobiology.
Neuroendocrine signaling.
Circadian and stress-response research.
Evidence context
The evidence base is old, limited and inconsistent. DSIP should not be presented as an established treatment for sleep or other conditions.
For research purposes only. Not intended for human consumption, self-administration or use as a medicine.
