What is DSIP?

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.

DSIP in published research

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

Animal studies report effects on stress hormones and body temperature.

The full list of DSIP papers is on PubMed, and most abstracts are free to read.

DSIP mechanism of action

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.

DSIP 5mg reconstitution and storage

With 5mg in the vial, common water volumes work out like this:

• 1mL of water: 5mg per mL
• 2mL of water: 2.5mg per mL
• 3mL of water: 1.67mg per mL

Let the vial warm to room temperature first. Run the water slowly down the side of the glass, then swirl or roll it until the powder is gone. Don’t shake it; foam is a sign of damaged peptide.

Before mixing, keep it at -20°C and out of the light. After mixing, the fridge at 2 to 8°C, and use it within about four weeks.

Planning a study with DSIP 5mg

Count the total milligrams across every group and time point, and round up. Running out halfway and switching lots adds a variable you didn’t plan for.

DSIP compared with similar peptides

DSIP is a nine-amino-acid peptide first isolated from rabbits in deep sleep. If you’re choosing between options, these are the usual alternatives:

• Semax is built on a fragment of ACTH and linked to BDNF in rodent studies
• N-Acetyl Semax is Semax with protective groups on both ends so it lasts longer in solution
• Selank is built on tuftsin and studied for anxiety through the GABA system
• N-Acetyl Selank is Selank with protective groups on both ends
• PE-22-28 is a short spadin analog that blocks the TREK-1 potassium channel

These reach the brain through different systems: BDNF, GABA, sleep regulation and a potassium channel. All of them are on our nootropic peptides page.

Often ordered with DSIP 5mg

• Semax 25mg, an ACTH(4-10) analog
• N-Acetyl Semax 25mg, a capped Semax analog
• N-Acetyl Selank 10mg, a capped Selank analog
• Pinealon 20mg, a bioregulator peptide
