Delta Sleep-Inducing Peptide (DSIP) Nasal Spray is a synthetic peptide formulation studied for its potential involvement in sleep regulation and neuroendocrine function.

DSIP has been explored in research settings for its effects on circadian rhythm signaling, hypothalamic activity, and hormonal balance, including interactions with stress-related pathways.

The intranasal delivery format is intended for non-invasive administration in investigational contexts, particularly in studies focused on sleep biology, recovery mechanisms, and neurological homeostasis.
