Buy DSIP (Delta Sleep-Inducing Peptide) in Canada
DSIP is named for what it did in the first experiments. In 1977 a Swiss team described a nine-amino-acid peptide that strengthened delta waves, the slow brain rhythm of deep sleep, in their laboratory recordings, and that effect gave it its name. We stock DSIP, and this guide covers what it is, what the research looks at and how to buy DSIP Canada-wide.

What DSIP is
DSIP stands for Delta Sleep-Inducing Peptide, and almost everyone uses the four letters. It is a neuropeptide, a short chain of nine amino acids. Schoenenberger and Monnier published its sequence in the Proceedings of the National Academy of Sciences in 1977, and a synthetic copy of the peptide reproduced the delta-wave effect in their EEG recordings.
DSIP today is made synthetically rather than extracted, and it dissolves readily in bacteriostatic water to a clear, colourless solution. You will see it written as DSIP, DSIP peptide or delta sleep-inducing peptide, and all three refer to the same compound. Our shop lists it under the full name, and the product page sets out its sizes and research areas.
What the research covers
About fifty years of published work on DSIP, much of it early-stage laboratory research, falls into four main areas. They line up with the research areas listed on our product page.
- Sleep architecture. The original work measured delta-wave activity on EEG, and sleep is still the area most closely tied to the name.
- Daily rhythm. A 1994 study measured DSIP in the blood every half hour for a full day and found a daily rhythm in its levels that closely tracked body temperature, which brings it into circadian-rhythm research.
- The stress response. A large body of laboratory work has looked at DSIP in stress models, including emotional stress, cold exposure and low oxygen.
- Neuroendocrine signalling. DSIP-like material has been found in the brain and the pituitary gland, and researchers have studied how it relates to stress hormones such as corticotropin.
In our shop DSIP is listed under recovery research, and you will also find it in the cognitive, energy and longevity collections.
Related peptides in rhythm and stress research
Two other peptides we stock are studied in neighbouring areas, and we cover each one in its own article.
- Epitalon: a four-amino-acid peptide modelled on a pineal gland extract, studied in melatonin and circadian-rhythm research.
- Selank: a seven-amino-acid peptide built on tuftsin, studied in stress-response and anxiety research, and stocked as a vial or a nasal spray.
DSIP shares the daily-rhythm theme with Epitalon and the stress-response theme with Selank, so the three make a natural set to read together.
DSIP format and specification
- Nine amino acids. The sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with the molecular formula C35H48N10O15 and a molecular weight of 848.8 g/mol.
- A lyophilised powder. DSIP ships freeze-dried, the form that keeps a peptide stable through shipping and storage until it is reconstituted.
- Cold, dry storage. Unopened vials store well cold, dry and away from light, and a reconstituted vial is kept refrigerated.
Where to buy DSIP Canada-wide
We stock DSIP in Canada, price it in Canadian dollars and ship it across the country.
- One vial or a pack of ten. The pack of ten works out cheaper per vial than buying single vials, which suits longer research series.
- Lab reports. Certificates of analysis from independent laboratories are published for each compound on our lab reports page, with purity above 99 percent.
- Bacteriostatic water on the same order. We also stock bacteriostatic water for reconstitution, so it can be added at the same time as the peptide.
- Tracked, discreet delivery. Orders go out by tracked Canada Post in discreet packaging, and the vial arrives sealed and ready for storage.
- Questions are welcome. A real person on our team answers email about DSIP or an order at [email protected].

Frequently asked questions
What does DSIP stand for?
Delta Sleep-Inducing Peptide. The name comes from the delta-wave, or deep-sleep, activity recorded in the laboratory experiments that first identified it in the 1970s.
Is DSIP a peptide or a hormone?
DSIP is classed as a neuropeptide: nine amino acids long, with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. Research has also looked at how it relates to stress and pituitary hormones, which is why it appears in neuroendocrine studies.
How is DSIP supplied?
As a lyophilised powder in a sealed vial, the form that keeps it stable in transit and in cold storage. For laboratory handling it is reconstituted with bacteriostatic water, and our guide to DSIP reconstitution has the details.
Can you buy DSIP in Canada?
Yes, as a research material from Canadian peptide suppliers. Vistara Labs stocks DSIP as a single vial or a pack of ten, with bacteriostatic water available on the same order. Every order ships from within Canada, so there is no customs step.
