What is DSIP?
DSIP (delta sleep-inducing peptide) is a naturally occurring nonapeptide, first isolated in the 1970s from the cerebral venous blood of rabbits in slow-wave sleep — which is where its name comes from. Despite five decades of study its receptor has never been definitively identified, which is itself part of why it remains a research subject.
It is supplied as a lyophilized powder at 10 mg. See the reconstitution guide and the reconstitution calculator for preparation.
Research context
DSIP is a reference compound in neuromodulation and sleep-architecture research. Models investigate its interactions with neuroendocrine and stress-response systems, including proposed modulation of corticosteroid signalling and neurotransmitter pathways relevant to sleep-cycle study designs.
The circadian and neuroendocrine angle places it near Epithalon, whose parent extract is pineal in origin, and alongside the neuroactive peptides Semax and Selank in stress-response designs.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and mass-spectrometry identity. See how to read a certificate of analysis and what a purity figure actually means; our process is described on the Research and Quality page.
Handling and storage
Kept cold and away from light while lyophilized; refrigerated once reconstituted and used within a shorter window. The storage guide covers both states, and bacteriostatic vs. sterile water explains why bacteriostatic water suits a multi-draw vial.
