Description
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide studied for its potential regulatory role in sleep architecture, particularly in promoting delta wave (slow-wave) sleep. It is a nonapeptide that has been observed to interact with various neuromodulatory and hormonal systems, and is commonly investigated in vitro for its influence on sleep cycles, stress modulation, cortisol regulation, and neuroendocrine balance. This 10mg lyophilized format is designed for research use in advanced neurobiology and sleep science applications.

DSIP is amazing! I had trouble falling asleep, but after using DSIP, I slept like a bear in hibernation. It’s so easy to use, just a quick spray under the tongue before bed. The value for money is unbeatable for the quality you get. Definitely recommend trying this product out!
