What It Is
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated in 1974. It was originally identified for its ability to induce slow-wave (delta) sleep. It has since been studied for its effects on stress, pain, hormone regulation, and longevity.
What It Does
DSIP improves sleep quality and duration, reduces stress and anxiety, normalizes cortisol and LH rhythms, reduces pain sensitivity, and has antioxidant effects. It is particularly useful for people with disrupted sleep patterns, high cortisol, or stress related health issues.
How It Works
DSIP modulates multiple neurotransmitter systems including GABA, glutamate, and serotonin. It normalizes the hypothalamic-pituitary axis, reducing dysregulated cortisol and LH patterns, and promotes slow-wave sleep stages, which are critical for growth hormone release, memory consolidation, and cellular repair.
Who Benefits Most
People with poor sleep quality or insomnia. People with high cortisol or HPA axis dysregulation. People with chronic stress or anxiety. Anyone looking to improve sleep architecture and recovery.
