DSIP — Delta Sleep Inducing Peptide
DSIP (Delta Sleep Inducing Peptide) is a naturally occurring nonapeptide (9 amino acids) first isolated from rabbit brain tissue in 1977. It is one of the earliest identified sleep-related neuropeptides.
Research Background:
DSIP has been investigated in neuroendocrine research for its interactions with sleep architecture, stress-related hormone signalling, and circadian rhythm pathways. The peptide crosses the blood-brain barrier, which is notable for its molecular size.
Published research has examined DSIP in sleep physiology models, cortisol regulation studies, and neuroendocrine signalling assays. The compound has been the subject of research for over four decades.

Frequently asked questions
Peptides are sold as research compounds for laboratory and research purposes and do not require a prescription. You can order freely.
Lyophilized peptides should be stored at -20°C or lower for long-term storage. For optimal preservation, store at -80°C if available. Keep peptides in their original sealed vials away from light, moisture, and temperature fluctuations.
Important tips:
- Allow vials to reach room temperature in a desiccator before opening to prevent moisture absorption
- Avoid repeated freeze-thaw cycles - only remove from freezer when ready to use
- Store in airtight containers with desiccant packs to prevent moisture exposure
- Keep away from direct light - use amber vials or wrap in aluminum foil
- Properly stored lyophilized peptides can remain stable for 2-4 years
Once reconstituted with bacteriostatic water, peptides should be stored at 2-8°C (refrigerator) and used within 2-4 weeks for optimal potency. Some peptides may remain stable for up to 8 weeks when properly refrigerated.
Storage guidelines for reconstituted peptides:
- Refrigerator storage (2-8°C): 2-4 weeks recommended maximum
- Freezer storage (-20°C): Possible but not recommended due to freeze-thaw damage
- Peptides containing Met, Cys, or Trp have shorter shelf life due to oxidation
- Peptides containing Asn, Gln are more prone to degradation in solution
- Create multiple aliquots to avoid repeated freeze-thaw cycles if freezing is necessary
Note: We recommend using reconstituted peptides within 2 weeks when possible, as potency gradually decreases over time.
Always use bacteriostatic water (BAC water) containing 0.9% benzyl alcohol for reconstituting peptides intended for multiple doses. Bacteriostatic water prevents bacterial growth and maintains sterility over several weeks of use.
Water types comparison:
- Bacteriostatic Water (RECOMMENDED): Contains 0.9% benzyl alcohol preservative, multi-use safe, prevents contamination, stable for 28 days after first puncture
- Sterile Water: No preservative, single-use only, risk of contamination with multiple punctures, not recommended for peptides
- Tap Water (NEVER USE): Contains impurities, minerals, chlorine, bacteria - will destroy peptides and cause contamination
- Distilled/Boiled Water (NOT RECOMMENDED): Not sterile, lacks antimicrobial properties, risk of bacterial growth
Use this simple formula to calculate dosage:
Concentration = Total mg in vial ÷ Total ml of water added
Example calculation:
- You have: 5mg BPC-157 vial
- You add: 2ml bacteriostatic water
- Concentration: 5mg ÷ 2ml = 2.5mg/ml
- If your dose is 250mcg (0.25mg): 0.25mg ÷ 2.5mg/ml = 0.1ml (10 units on insulin syringe)
Common reconstitution volumes:
- 2mg vial + 2ml water = 1mg/ml concentration
- 5mg vial + 2ml water = 2.5mg/ml concentration
- 10mg vial + 2ml water = 5mg/ml concentration
Tip: Use our online peptide calculators or create a dosing chart when you reconstitute to avoid calculation errors.
