DSIP 5mg

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide that was first isolated from the cerebral venous blood of sleeping rabbits in the 1970s. This small, nonapeptide is primarily known for its role in regulating sleep cycles, particularly promoting deep, restorative slow-wave sleep (delta sleep). DSIP is found in various tissues, including the brain and hypothalamus, and has been extensively studied for its potential influence on stress adaptation, pain modulation, and neuroprotection. While naturally present in minute amounts, synthetic forms are used in research and some clinical settings to mimic the body's own peptide.
