DSIP (Delta Sleep-Inducing Peptide)

Description

Pure Rawz DSIP is a neuropeptide, available as freeze-dried vials, a nasal spray and sublingual tablets. It’s tested to 99% purity or higher and sold strictly for lab research.

DSIP explained

Delta sleep-inducing peptide (DSIP) is a nine-amino-acid peptide first isolated from rabbit blood in 1977 by Schoenenberger and Monnier. It was named for its effect on slow-wave sleep in rabbits.

Its natural role is still unclear.

How it works

DSIP was found while looking for compounds that drive deep sleep. Researchers named it for the delta waves of slow-wave sleep it seemed to boost in rabbits.

Later work suggested its effects are broader and less specific: it affects stress hormone release, body temperature and pain signaling. No receptor has been identified, which is part of why it’s still an open research question.

What studies say about DSIP

Small human studies in the 1980s looked at sleep and withdrawal, with mixed results.

Animal studies report effects on stress hormones and body temperature.

Options and prices

Choose the option that fits your study:

• Peptide, 2mg: $29.99
• Peptide, 5mg: $59.99
• Nasal Spray, 50mcg per spray/5mg: $79.99
• Sublingual Tablets, 100mcg per tablet/50ct/5mg: $79.99

These vials are lyophilized powder. Mix them with bacteriostatic water when you’re ready to work with them, and keep unmixed vials cold until then.

The nasal spray comes ready to use in a metered bottle, so there’s nothing to mix. The size shows how much each spray delivers and the total in the bottle.

Sublingual tablets are pressed to dissolve under the tongue. Each one holds a fixed amount, printed in the size option, so there’s no measuring.

Study design notes

Researchers who work with peptides tend to order a small vial first to check solubility and handling, then move to larger sizes once the protocol is settled.

Keep a log of the batch number, the mixing date and the volume of water used. If results drift between runs, those three details are usually where the answer is.

A typical peptide study plan lists the model, the endpoints, the form you’ll use, and how long each vial will last once mixed. Writing that down first makes ordering simple, because it tells you the size and number of vials you need.

Mixing and concentration

The liquid you add sets the concentration. For a 2mg vial:

• 1mL of bacteriostatic water gives 2mg/mL
• 2mL of bacteriostatic water gives 1mg/mL

Add the water slowly along the inside of the vial and roll it gently until the powder dissolves. Shaking can damage peptide chains.

Purity and batch testing

Every batch is tested before it goes on sale. Identity is checked by mass spectrometry, and purity by HPLC, with a target of 99% or higher.

Each container is labeled with the product, the amount and the batch number. Email us that number and we’ll send the certificate of analysis for your batch.

Storage and shelf life

Freeze-dried vials keep best in the freezer, and a fridge is fine for a few weeks. Once reconstituted, keep it refrigerated and finish it within roughly 28 days. Keep nasal spray bottles in the fridge once opened, capped and upright.

Keep the container sealed at room temperature, away from heat, moisture and sunlight.

Write the date you opened or mixed it on the label, so anyone else in the lab knows how old it is.

Safe handling

Treat it as a lab chemical. Gloves and safety glasses are the minimum, and a clean, uncluttered workspace cuts down on mix-ups.

Store prepared solutions apart from untouched stock, and record who mixed what and when.

Supplies to have on hand

• Bacteriostatic Water for reconstitution, or Sterile Water if you’ll use the whole vial at once
• sterile insulin-type syringes or pipettes for measuring
• alcohol swabs for the vial stopper

DSIP questions

What forms does it come in?

Freeze-dried vials, a nasal spray and sublingual tablets. Pick the one you want from the dropdown on this page.

Is DSIP in stock?

Yes. It’s in stock and ships from our warehouse after your order clears.

Does it come with a certificate of analysis?

Yes. Every batch is tested, and we’ll email the certificate of analysis for your batch number on request.

Can it be used in people or animals?

No. It’s sold for laboratory research only and isn’t approved for human or veterinary use.

What do I mix it with?

Most labs use sterile bacteriostatic water. Add it slowly down the side of the vial and swirl gently until the powder dissolves. Don’t shake it.

How should I store it?

Follow the storage section above. In short: cold and dark for freeze-dried vials, room temperature and dry for capsules, tablets, powders and liquids, unless the label says otherwise.
