What is DSIP?
DSIP is a neuromodulatory peptide: instead of acting as a direct transmitter, it appears to modulate the activity of other brain systems. It was named for its relationship with the delta waves of deep sleep in the studies that described it.
Research context
The preclinical literature on DSIP has explored its relationship with sleep regulation, the stress response and certain neuroendocrine rhythms in animal models.
These findings belong to the field of research and do not constitute evidence of efficacy in humans. DSIP is offered for research use only.
