Product Information
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring peptide studied for its influence on sleep regulation and neuroendocrine function. It is commonly explored for its potential to promote deeper, more restorative sleep cycles while supporting overall neurological balance.
Beyond sleep, DSIP has been associated with broader benefits such as stress response modulation, mood support, and improved recovery through enhanced hormonal balance. It is also studied for its potential role in regulating cortisol levels, which may contribute to better sleep quality and reduced fatigue over time.
This peptide is often included in protocols focused on sleep optimization, mental recovery, and overall well-being. Supplied as a 15mg lyophilized powder, it ensures stability and precise reconstitution. At Peptides Costa Rica, DSIP is manufactured under strict quality standards to ensure purity, consistency, and reliability.

Common Questions
Frequently Asked Questions
What is DSIP and what is it studied for? +
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring 9-amino-acid neuropeptide studied in research models for its role in sleep regulation, neuroendocrine modulation, and stress response. The 15mg vial is supplied as lyophilized powder for research use only.
How much BAC water should I add to a 15mg DSIP vial? +
A common reconstitution for a 15mg vial is 1.5–3 mL of bacteriostatic water. Adding 3 mL gives 5 mg/mL (5,000 mcg/mL). DSIP is also soluble in 0.1% acetic acid if needed. Use the reconstitution calculator on this page to determine syringe units for your target dose.
How many doses does a 15mg DSIP vial provide? +
With 3 mL BAC water (5 mg/mL), the 15mg vial provides approximately 30 doses at 500 mcg per dose, or 60 doses at 250 mcg per dose. The large vial size makes DSIP cost-effective for longer research protocols.
Why is DSIP supplied in a 15mg vial rather than a smaller size? +
DSIP research protocols typically use it over extended periods, and the 15mg vial size provides a larger supply per order. The larger vial also offers a lower cost-per-dose compared to smaller sizes, making it practical for sustained research programs.
How should reconstituted DSIP be stored? +
After reconstitution, refrigerate at 2–8 °C and use within 28–30 days. The sealed lyophilized vial should be stored frozen at ≤ −20 °C, away from light. DSIP is soluble in water but sensitive to prolonged light exposure, so always protect it from direct light.
