Description
Our DSIP 5mg vial holds 5mg of lyophilized DSIP, a neuropeptide, tested by HPLC-MS. It’s for in-vitro and lab research only.
The current batch tested at 7.5mg per vial, above the 5mg on the label.
About DSIP (delta sleep-inducing peptide)
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 DSIP acts in the lab
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 the research says 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.

DSIP 5mg vs related compounds
DSIP 5mg is easier to place once you see it next to the compounds it’s usually compared with. DSIP is a nine-amino-acid peptide first isolated from rabbits in deep sleep. The others:
- N-Acetyl Semax Amidate is Semax with protective caps on both ends, linked to BDNF in rodent work
- N-Acetyl Selank Amidate is capped Selank, studied for anxiety through the GABA system
- PE-22-28 is a short spadin analog that blocks the TREK-1 potassium channel
These are short neuropeptides studied for focus, anxiety, sleep and mood, and each works through a different system in the brain. See them all on our nootropic peptides page.
DSIP 5mg reconstitution and concentration
The amount of liquid you add sets the concentration. For a vial holding 5mg:
- 1mL of bacteriostatic water gives 5mg/mL
- 2mL of bacteriostatic water gives 2.5mg/mL
- 3mL of bacteriostatic water gives 1.67mg/mL
Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.
Most labs use sterile bacteriostatic water, which has 0.9% benzyl alcohol to keep the vial clean between draws. Warm the sealed vial to room temperature, add the water slowly along the glass wall and swirl gently until it’s clear. Never shake it.
Storing DSIP 5mg
Store sealed vials of DSIP 5mg in the freezer at -20°C, out of direct light. Mixed solution goes in the fridge at 2 to 8°C and should be used within 28 days.
Let a frozen vial warm up to room temperature before you open it. Cold glass pulls moisture out of the air, and that moisture is what degrades dry peptide.
DSIP 5mg purity and lab testing
Every batch of DSIP 5mg is checked by HPLC-MS. HPLC separates the sample and measures how much of it is the target compound, and mass spectrometry confirms the molecular weight, so one test covers both purity and identity. DSIP 5mg tests at over 99% purity.
After freeze-drying, each vial is vacuum-sealed. Keeping air and moisture out is what lets lyophilized peptide stay stable for months in a freezer.
Write the batch number from the label into your lab notes. If a result looks odd later, you can tie it back to the exact batch you used.
