What we know so far

No independent test of PureRawz's DSIP yet

DSIP generally tests around 98.3% purity across 4 independent certificates — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
Price sits within the normal range for DSIP — no cheap-fake red flag.

How to verify this yourself

To verify before you buy: ask PureRawz for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

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.

Understand this compound

What is DSIP?

Limited human dataa.k.a. Delta Sleep-Inducing Peptide

The '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.

SleepCognitive & mood

⚠

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.

The lab evidence

What we could verify

Each row is a separate question with its own answer — one green row never vouches for the rest.

Identity

Unknown

No independent test on record for this listing.

Measured purity

Unknown

No independent purity measurement on record.

Batch traceability

Unknown

No batch on this listing matches an independent record.

Sterility

Not tested

A purity certificate doesn't measure this — no such test on record.

Dose accuracy

Unknown

Not something VialGrade measures — no test on record.

These certificates are for DSIP across every maker VialGrade tracks — not necessarily PureRawz’s own stock. This listing’s specific evidence is the matrix above.

Independent testing

Independent lab tests on record for DSIP

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.

Nothing to verify

No test for this vendor — but DSIP is independently characterized

This vendor doesn't advertise independent testing, and we hold no COA tied to PureRawz specifically. We do hold 4 independent certificates for DSIP (median 98.3% purity) from other makers — real market context for what this compound tests at, though not proof of this vendor's product.

US legal status

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.
