DSIP (delta sleep-inducing peptide) is a nine-amino-acid neuropeptide first isolated from rabbit cerebral venous blood during induced slow-wave sleep. It is the canonical tool compound in delta-wave and circadian research.
Reference data researchers look up before ordering dsip. Every lot ships with documentation matching the batch number printed on the vial.
Each dsip lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.
DSIP ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.
PX1 Research synthesizes and fills dsip in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Delta sleep-inducing peptide, named for the delta-wave sleep activity observed when it was first isolated.
Nine — it is one of the shortest neuropeptides in common research use.
Yes. Every dsip lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
