DSIP (5mg)

Delta-Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide extensively studied for its role in chronobiology. DSIP has demonstrated the ability to induce deep delta-wave sleep and stabilize circadian rhythms in both animal models and human clinical trials. It functions as a sophisticated neuromodulator that crosses the blood-brain barrier to reduce basal corticotropin levels, stimulate growth hormone release, and mitigate the physiological markers of acute stress—making it a primary candidate for research into sleep architecture, HPA-axis regulation, and neuroprotection.
