DSIP

DSIP (Delta Sleep-Inducing Peptide)

Delta Sleep-Inducing Peptide, or DSIP, is a naturally-occurring peptide made of nine amino acids, isolated from the central nervous system of experimental models of electrically induced sleep. DSIP is posited to regulate the sleep cycle, as suggested by its name, but may also play a role in regulating various physiological processes. Suggested to induce delta sleep in test models, this neuropeptide also appears to impact electrophysiological activity and possibly regulate the neurotransmitter levels in the brain.⁽¹⁾

DSIP peptide was first characterized and examined from 1963 to 1977 and has since been widely studied by scientists.⁽²⁾ Initially regarded only for its potential as a sleep-including factor, DSIP was soon suggested to induce other potential actions, such as mitigating pain, sleep cycle regulation, and mitigating withdrawal.
