Much better sleep!

Definitely noticed an uptick in restorative sleep. Getting out of bed is much easier now. It doesn't make you sleepy unless you take too much. It just makes your circadian rhythm better and improves sleep quality.

DSIP

Didn't notice anything major until a week or two into it when sleep pattern started becoming more regular and better quality. Don't get the afternoon crash anymore. This was the only thing that changed over that time so it must be the cause.

View Certificate of Analysis
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.
