Overview
What Is DSIP?
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit brain tissue. It is studied for its effects on sleep architecture, stress response modulation, and endocrine regulation in preclinical research models.
Also known as Delta Sleep-Inducing Peptide, DSIP is supplied as a lyophilised research peptide for laboratory use only. Research suggests DSIP modulates slow-wave sleep patterns and normalises disturbed sleep architecture in animal models. Studies also examine effects on ACTH/cortisol rhythms, pain perception thresholds, and oxidative stress markers in various research contexts.
Mechanism
How DSIP Works — Research Mechanism
Research suggests DSIP modulates slow-wave sleep patterns and normalises disturbed sleep architecture in animal models. Studies also examine effects on ACTH/cortisol rhythms, pain perception thresholds, and oxidative stress markers in various research contexts.
- Primary research focus: sleep, nootropic, specialty
- Mechanism studied in published preclinical and clinical literature
- Third-party HPLC/MS identity verification on every EvoPeak batch
- Supplied strictly for laboratory research use
Research reference
DSIP Dosage — Published Research Protocols
The following reference points are drawn from published research literature. These figures are provided for research reference only and do not constitute dosing recommendations. DSIP is sold strictly for laboratory research use.
| Protocol tier | Published research detail |
|---|---|
| Research reference | Published literature varies by model and endpoint — consult primary sources for protocol-specific dosing in laboratory settings |
| Administration route | Subcutaneous injection is most common in published peptide research protocols |
| Frequency | Dosing frequency depends on compound half-life and research design — daily to weekly intervals reported in literature |
| Available vial sizes | 10 mg, 15 mg — select based on your laboratory protocol requirements |
| Titration | Many research protocols start at lower doses and escalate to assess receptor response and tolerability in models |
Research use only: FOR LABORATORY RESEARCH USE ONLY. Not for human consumption, injection, or therapeutic use. All products are sold strictly as research chemicals. By purchasing, you confirm you are 18+ and agree to use products solely for legitimate research purposes.
Safety research
DSIP Side Effects — Research Findings
Side effect profiles documented in published DSIP research depend on dose, route of administration, and model system. The following are commonly reported findings from research literature — not from personal use contexts.
- Mild nasal irritation when intranasal routes used in published Semax/Selank research
- Injection site reactions for subcutaneous administration routes
- Generally well-tolerated in nootropic peptide literature at research doses
- No significant dependence or withdrawal reported in animal model studies
Handling
Reconstituting DSIP
DSIP is supplied as a lyophilised powder and must be reconstituted before use in laboratory protocols. Use bacteriostatic water (0.9% benzyl alcohol) for multi-dose vials. Inject diluent slowly down the inside wall of the vial — do not shake vigorously.
Bacteriostatic water is available from EvoPeak. Store reconstituted peptide at 2–8°C and lyophilised powder at −20°C.

What is the DSIP dosage used in research?
Published research uses varying doses depending on the model and endpoint. EvoPeak supplies 10 mg and 15 mg vials. All dosage information is for research reference only and does not constitute recommendations.
What are the side effects of DSIP?
Side effect profiles in published research depend on dose, route, and model system. Consult primary literature for compound-specific findings. All information is drawn from research contexts, not personal use.
Can I buy DSIP in Australia?
Yes. EvoPeak supplies research-grade DSIP to Australian researchers with HPLC/MS verification, batch-specific COA documentation, and domestic shipping. Products are for laboratory research use only.
How do I get DSIP in Australia?
Order from the EvoPeak shop page, select your vial size, review the COA, and checkout with local Australian fulfilment.
How do I reconstitute DSIP?
DSIP is supplied as lyophilised powder. Reconstitute with bacteriostatic water, inject diluent slowly down the vial wall without shaking, and store at 2–8°C once reconstituted. Bacteriostatic water is available from EvoPeak.
What purity standard does EvoPeak DSIP meet?
