DSIP was isolated in 1977 by Schoenenberger and Monnier from the blood of rabbits during electrically induced sleep, and named for its apparent ability to promote delta (slow-wave) sleep when transferred to other animals. Nearly five decades later, its natural receptor and mechanism are still not fully established, which keeps it an open research question.
Early animal and small human studies reported changes in slow-wave sleep; later results were inconsistent across models.
Other work examined effects on stress hormones, body temperature regulation and antioxidant enzymes.
Honest caveat: the findings above come from published laboratory and preclinical research, or from clinical studies of the compound class. They describe what has been studied, not what this product will do.
| Size | Price (pre-order) | Per mg |
|---|---|---|
| 2 mg | $35.00 | $17.50 |

Store the lyophilized powder at −20 °C long term or 2–8 °C short term, protected from light and moisture. After reconstitution with bacteriostatic water, keep refrigerated and avoid repeated freeze-thaw cycles.
Tap a question to reveal the answer.
Delta sleep-inducing peptide, a nine-amino-acid peptide first isolated in 1977 and studied in sleep and neuroendocrine models.
No specific receptor has been conclusively identified, which is one reason DSIP remains an active research topic.
TrueLabs ships DSIP from inside Canada with tracking, usually in 2-4 business days, with a batch-specific third-party COA and no customs.
