DSIP (5mg)

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.
