DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide first isolated from rabbit cerebral venous blood during slow-wave (delta) sleep induction experiments by Monnier et al. in 1974. Its endogenous presence has since been confirmed in various tissues, including brain, pituitary, and peripheral blood.
In laboratory research, DSIP is studied for its interactions with CNS sleep-pathway signalling, particularly delta-wave induction mechanisms, as well as neuroendocrine axis modulation including stress hormone pathway interactions. Researchers investigate its binding characteristics in hypothalamic and limbic region cell models, and its effects on corticotropin and somatotropin release in controlled non-clinical assay systems.
DSIP is also used as a research tool in studies of oxidative stress and neuroprotection pathway modelling. Supplied as a lyophilised powder in a sterile sealed vial. Each batch is tested for identity, purity, and appearance before release.
All Mega Lab Peptides products are supplied strictly for laboratory research use. Not medications, supplements, foods, or cosmetics. Not for human or veterinary use. By purchasing you confirm you are a qualified researcher aged 18 or over.
Remove the vial from cold storage and allow it to reach room temperature before opening. This prevents condensation forming inside the vial and disturbing the lyophilised powder.
Always reconstitute with bacteriostatic water (BW). Avoid distilled or sterile water for long-term storage — BW contains 0.9% benzyl alcohol which preserves peptide stability and prevents microbial growth.
Insert the needle into the vial and allow BW to run slowly down the inside wall. Do not inject directly onto the lyophilised powder — the pressure can degrade the peptide structure.
Gently swirl the vial — never shake. Continue until the powder is fully dissolved and the solution is clear. Shaking introduces air bubbles and can cause aggregation.
Once reconstituted, store at 2–8°C and use within 30 days. Never freeze a reconstituted vial. Lyophilised (un-reconstituted) vials should be stored at –20°C, away from direct light.
