DSIP

Research & Reconstitution Information

DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide first isolated in the 1970s that has been studied in animal and early human research in connection with sleep-stage regulation (particularly slow-wave/delta sleep) and the hypothalamic-pituitary-adrenal (stress) axis. The evidence base is old, small and inconsistent: the one placebo-controlled human insomnia trial found only weak effects, and a separate human study found no measurable effect on stress-hormone response at all, contradicting earlier animal findings. A peer-reviewed review describes DSIP's biological role as still unresolved, without a confirmed receptor or gene. This is one of the more scientifically uncertain compounds in our catalogue, described honestly rather than oversold. Reconstitute with bacteriostatic water, swirl gently (do not shake), and store unreconstituted vials at 2-8°C short-term or -20°C for long-term storage. Refrigerate (2-8°C) once reconstituted. For laboratory research purposes only.

Certificate of Analysis

All products are independently tested by accredited third-party laboratories. Results confirm identity, purity, and potency.

How to Reconstitute

1. 1.Clean the vial top with an alcohol swab, then slowly release solvent along the inside wall of the vial — don't squirt directly onto the powder.
2. 2.Let it dissolve on its own for a few minutes. Swirl gently if needed — do not shake.
3. 3.Refrigerate (2-8°C) once reconstituted.
