DSIP

DSIP, or Delta Sleep-Inducing Peptide, is a synthetic nonapeptide historically investigated in laboratory and early clinical research involving sleep regulation, circadian biology, neurological signalling and physiological stress-response pathways.

Although some early studies reported changes in sleep quality and sleep-related measurements, later scientific reviews concluded that DSIP’s proposed role as a natural sleep-regulating factor remains uncertain and poorly established.

Storage

Store according to the conditions specified on the product label or certificate of analysis. Keep the container securely sealed and protected from excessive heat, moisture and direct sunlight.

Important Notice

DSIP is not an FDA-approved medicine and must not be promoted as a treatment for insomnia, anxiety, pain, withdrawal symptoms or another medical condition. The FDA has scheduled emideltide—another name used for DSIP-related substances—for discussion regarding potential use in pharmaceutical compounding on July 24, 2026. Consideration for a compounding list does not constitute FDA approval or confirmation of safety or effectiveness.
