Delta Sleep-Inducing Peptide (DSIP)

DSIP works by increasing growth hormone and lowering cortisol and somatostatin. This helps patients fall asleep and stay asleep.

DSIP (Delta Sleep-Inducing peptide) is a neuromodulator and natural sleep-promoting nonapeptide with many other physiologic functions. It is predominately found in the brain and easily passes the blood-brain barrier. It has been used for the treatment of poor sleep, pain conditions, stress-related symptoms, low testosterone (via stimulation of LH), and even sometimes as an antioxidant and anti-cancer protein. It exhibits a pronounced stress protective action and decreases stress-induced metabolic and functional disorders in human and animal organisms exposed to a variety of stresses. In humans, DSIP is shown to directly impact the secretion of adrenocorticotropic hormone (ACTH), luteinizing hormone (LH) and growth hormone (GH). It may also play a role in the regulation of circadian rhythms.
