DSIP
Mechanism.
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit brain in 1977. It was named for its ability to induce delta-wave (slow-wave) sleep in rabbits, though its sleep-promoting effects in humans have been inconsistent across studies. It has also been investigated for stress modulation, pain, and hormonal regulation.
Think of DSIP as a volume knob for your brain's stress and sleep systems — rather than targeting one specific pathway, it seems to gently turn down the stress signals and turn up the conditions that favor deep, restorative sleep.
