Product overview
Generic Peptides DSIP - 2 and 5 mg Research Vials
Generic Peptides DSIP is delta-sleep-inducing peptide, a nine amino acid neuropeptide supplied as a lyophilized research powder in 2 mg and 5 mg vials. The name comes from the way the material was first isolated: it was pulled out of the cerebral venous blood of sleeping rabbits in 1974, and early animal work showed slow-wave and spindle activity on the EEG after it was placed into the brain ventricles. It is studied today as a sleep-architecture research peptide rather than an approved drug, and it is explored alongside Selank and Semax.

Variant Comparison
Both vials hold the same nonapeptide; only the amount of powder differs.
| Variant | Dosage | Form and quantity | Best use |
|---|---|---|---|
| DSIP 2 mg | 2 mg | Vial | Short |
| DSIP 5 mg | 5 mg | Vial | Extended |
The 5 mg vial holds more material than the 2 mg vial and suits longer sampling runs, and the 5 mg size is also the one that carries a U.S. domestic option. For sleep-architecture work the pineal peptide Epitalon is a common companion, since the two are studied in the same circadian research setting.
How DSIP Works
The peptide is the nonapeptide WAGGDASGE, with a mass near 850 daltons, the formula C35H48N10O15 and the CAS number 62568-57-4. Descriptions of its action point to NMDA receptor signalling, and animal experiments injected into the brain ventricles produced spindle and delta EEG activity with reduced movement. Human data are thin: some small studies reported more slow-wave sleep and less REM, while others found no clear link, so the compound remains a research tool whose sleep effect is not settled.
Reconstitution & Storage
Add bacteriostatic water down the wall of the vial and swirl, do not shake. Divide the milligrams on the vial by the millilitres added to read mg per mL: a 2 mg vial with 2 mL gives 1 mg/mL, so 0.1 mL on a U-100 syringe reads 100 mcg. Keep the sealed powder at 2-8 C or -20 C, protected from light, and the mixed solution at 2-8 C in the short term.
Dosage & Administration
No human dose is stated here and the vial is not a medicine. DSIP is not an approved medicine in the United States or the European Union and has no human pharmacokinetic profile, so nothing on this page is a treatment protocol or a dosing guide.
For laboratory research only, not for human or veterinary use. Information provided is for educational purposes only and does not constitute medical advice. Consult a qualified healthcare professional before use. DSIP is supplied as a lyophilized powder and stays stable when the vial is kept cold, dry and out of light.

FAQ
Before you ask
Questions, answered
DSIP is delta-sleep-inducing peptide, the nonapeptide WAGGDASGE with a mass near 850 daltons, the formula C35H48N10O15 and the CAS number 62568-57-4. The name dates from 1974, when researchers isolated it from the cerebral venous blood of sleeping rabbits and found that it produced slow-wave and spindle EEG activity in test animals. It has no approved medical use.
The picture is mixed. Some small human reports describe more slow-wave sleep and less REM after DSIP, while other studies found no clear connection to sleep at all, and the reviews note that the evidence is inconsistent. Because no large controlled trial confirms an effect, the compound is best treated as a research material whose central action is not established rather than a working sleep agent.
There is no approved product, so no label-based safety profile exists. Reported observations include daytime drowsiness when material is given late, headache after injection and a groggy feeling the following morning. Injection-site reactions are common to the route. Because the central effect itself is unpredictable in the sources, no reliable statement about frequency or dose dependence can be made.
No human pharmacokinetic profile has been established. In laboratory conditions the peptide is broken down quickly by a specific aminopeptidase, with a reported in vitro half-life of about 15 minutes, and secondary sources place the range anywhere from a few minutes to 30 or 40 minutes. Those figures are not confirmed in humans, so they should be read as laboratory context only.
Add bacteriostatic water down the side of the vial and swirl, do not shake. Divide the milligrams on the vial by the millilitres added to read mg per mL: a 2 mg vial with 2 mL gives 1 mg/mL, so 0.1 mL on a U-100 syringe reads 100 mcg. Keep the sealed powder at 2-8 C or -20 C, protected from light, and the mixed solution at 2-8 C.
No. DSIP holds no approval from the FDA, the EMA or any other major regulator, and it is not listed as a medicine in those markets. Products sold under this name are research materials. The absence of approval is not a statement about safety or effect either way, it simply means no regulator has reviewed the compound for human use.
Both vial sizes are listed on this page as research material, with international checkout and a U.S. domestic option on the 5 mg vial. International shipping runs about 35 dollars with a transit window of four to ten days, the domestic route runs about 25 dollars over two to five days, and orders are handled within one to two business days. Stock and prices are shown in the options above.
