Description
DSIP 5mg from Polaris Peptides is a lyophilised research peptide with over 99% purity confirmed by HPLC-MS. DSIP is a neuropeptide (also known as Delta Sleep-Inducing Peptide), supplied vacuum-sealed and sold strictly for laboratory research.
At $40.00 this vial works out to $8.00 per milligram.
What Is DSIP 5mg?
DSIP (delta sleep-inducing peptide) is a nine-amino-acid neuropeptide first isolated in 1977 from the blood of rabbits in induced sleep. It was named for its reported ability to increase delta-wave (deep) sleep in animal studies.
Since then, researchers have studied DSIP for its effects on sleep architecture, stress hormone release and pain. Its exact receptor is still not identified, which keeps it an open question in sleep research. This batch was tested at 7.5mg per vial against a 5mg label.

DSIP Research Areas
Published studies on DSIP cover several areas. The list below summarises the main ones so you can see where it fits your work.
- Sleep architecture: delta-wave sleep and sleep-stage patterns.
- Stress hormones: ACTH and cortisol regulation.
- Pain modulation: analgesic effects in animal models.
- Circadian rhythm: interaction with daily biological cycles.
Storing and Handling DSIP 5mg
Store unopened vials at −20 °C, where the dry powder stays stable for long periods. Before reconstitution, let the vial reach room temperature to stop condensation forming inside. Add bacteriostatic water or another lab-grade solvent slowly down the side of the vial and swirl gently rather than shaking. Once reconstituted, keep it at 2–8 °C and complete your work within 28 days.
Why Order DSIP From Polaris Peptides
Every batch of DSIP we sell is checked by HPLC-MS for identity and purity before it is listed. Vials are vacuum-sealed to keep moisture out and labelled with the exact amount. If you are comparing suppliers, ask for the batch analysis and check it against the label. That is the standard we hold ourselves to.
How DSIP 5mg Is Tested
We use two methods together. High-performance liquid chromatography (HPLC) separates the contents of a sample so we can see how much of it is the target compound and how much is anything else, such as truncated sequences or leftover synthesis reagents. Mass spectrometry (MS) then weighs the molecules, which confirms that the main peak really is DSIP and not a look-alike. A result above 99% on both counts is what earns a batch a place in our catalogue. Lots that fall short are not sold.
