Understand this compound
What is DSIP?
Limited human dataa.k.a. Delta Sleep-Inducing PeptideThe 'deep-sleep' molecule, first found in the blood of sleeping rabbits. Studied — with mixed results — for whether it nudges the brain toward restful sleep and dampens stress hormones.
Good to know: Human studies are small, decades old, and mostly used intravenous administration rather than how it is commonly sold today, with inconsistent conclusions about clinical benefit.
How does DSIP work?
The science
A nonapeptide originally isolated from rabbit cerebral venous blood during slow-wave sleep, proposed to modulate sleep-wake regulation and dampen HPA-axis stress reactivity (ACTH/cortisol responses) rather than act as a classic sedative.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is DSIP researched for?
Studied for insomnia and stress-related sleep disturbance.
- SleepStudied in sleep-cycle and stress-recovery research.
- Cognitive & moodStudied in memory, focus, mood, and neuroprotection research.
How far has the research gone?
Limited human data — several small human studies (mostly intravenous) from the 1980s-90s show mixed results, with some finding modest sleep benefits and others finding effects too weak to be clinically meaningful.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.

Every DSIP listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 38 are here: the last 6 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Independent testing
DSIP — independent lab tests
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
How does this data get here?
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
What a certificate does & doesn’t prove
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.

What the research says
Scientific evidence & regulatory status
What the published literature actually shows about DSIP — separate from any vendor’s marketing. Each finding links to its paper. This is education, not medical or dosing advice.
Regulatory status
No FDA-approved drug
Not FDA-approved. FDA placed emideltide — its formal name for DSIP — in category 2 (significant safety risks) for pharmacy compounding, citing an absence of safety information; the nomination was later withdrawn. FDA reviewed it again in July 2026 and concluded the evidence weighs against adding it to the compounding list.
Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
Research notes aren’t product proof
Research summaries describe published literature and market data only. They do not establish the identity, quality, safety, or legal status of any listed physical product.
