Product Description

DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide originally discovered in the cerebrospinal fluid of sleep-deprived animals. This naturally occurring peptide sequence has attracted significant research attention for its sleep-promoting properties and potential neuromodulatory effects. DSIP is valued by researchers investigating sleep architecture, circadian regulation, and natural sleep-inducing mechanisms.

Expert Insight

“DSIP's discovery through natural sleep physiology makes it a uniquely credible tool for sleep research. Unlike pharmaceutical sleep aids, DSIP mimics endogenous sleep-promoting pathways, offering researchers a physiologically-grounded approach to investigating sleep architecture and circadian processes.”

Research Pairing Suggestions

+Epithalon

Researchers studying circadian and sleep-related physiology commonly pair these because DSIP is a sleep-inducing peptide while Epithalon supports circadian rhythm regulation, creating complementary sleep-wake cycle research.

View
+Selank

This pairing addresses both sleep quality and emotional regulation in research—DSIP promotes sleep initiation while Selank offers anxiolytic and mood-supporting effects for holistic neurophysiology investigation.

View
+Melatonin

Both target circadian and sleep pathways through different mechanisms—DSIP acts as an endogenous sleep signaler while exogenous Melatonin augments circadian phase control, useful in sleep architecture studies.

Research Literature — DSIP

The following is a summary of published research literature. This information is provided for educational reference only and does not constitute medical advice or research amount guidance.

Research Amounts in Literature

In published studies, researchers have administered DSIP at doses of 25–100 µg/kg or approximately 100–300 µg per administration in human research settings.

Frequency Protocols in Research

Published literature on DSIP reports once-daily evening administration protocols, typically administered 30–60 minutes before the sleep period, over 5–14 day cycles.

Reconstitution Concentrations in Research

Published literature reports reconstitution of 10 mg vials in 3–5 mL bacteriostatic water, yielding concentrations of 2–3.3 mg/mL. Higher water volumes improve precision for the small µg-level doses used in sleep research.

Typical Syringe Ranges in Research

At 2 mg/mL (5 mL water), a 200 µg dose equals 10 units (0.1 mL). Typical research administration volumes range from 5–15 units.
