What is DSIP (Delta Sleep-Inducing Peptide)?
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide first isolated from rabbit cerebral venous blood in 1974. As its name suggests, it promotes delta (slow-wave) sleep — the deepest, most restorative stage of sleep. DSIP is widely distributed throughout the brain and peripheral organs and is thought to have a broad regulatory role in neuroendocrine function. Research has shown it to modulate cortisol, somatostatin, and LH levels, while also demonstrating analgesic (pain-reducing), antioxidant, and anti-stress effects. It may also have applications in treating withdrawal symptoms from alcohol and opioids.

Common Stacks
DSIP (Delta Sleep-Inducing Peptide) is frequently combined with the following peptides for synergistic effects. Click any peptide to compare profiles before deciding.
DSIP promotes deep sleep while Ipamorelin maximises the GH pulse that naturally occurs during sleep - synergistic for recovery.
Both influence the pineal gland and circadian rhythm - together they are used for sleep restoration and anti-aging protocols.
Side Effects & Risks
Adverse effects reported in the research literature. All data sourced from preclinical and clinical study reports.
Dosing Data from the Literature
Doses referenced below are sourced from published preclinical and clinical studies. Use the peptide dose calculator to convert these values to injection volume.
Typical research dosing: 100–250 mcg subcutaneously, administered 30–60 minutes before desired sleep. Some protocols use 500 mcg to 1 mg for more pronounced effects. Cycles of 5–7 days followed by breaks are recommended.
Administration in Research Settings
Standard reconstitution and administration methodology for laboratory research use.
Reconstitute with bacteriostatic water. Inject subcutaneously 30–60 minutes before bedtime. Start with lower doses to assess sensitivity. Avoid combining with sedatives or alcohol. Short cycles help prevent receptor desensitization.
