Overview
What is DSIP?
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide (~849 Da) that has been investigated for its effects on sleep architecture in controlled human studies. The compound has been explored in research examining sleep quality and neuroendocrine function.
Key Information
Primary Research Focus:
– Modulation of sleep architecture (total sleep time, awakenings, sleep latency)
– Effects on EEG patterns linked to slow-wave (delta) sleep
– Interactions with ACTH/cortisol dynamics and neuroendocrine pathways
Routes of Administration Studied:
– Intravenous (slow infusion) — most common in human literature
– Intranasal
– Subcutaneous (primarily animal models)
Dosing Protocol
Most-Studied Human Dose: Approximately 25 nmol/kg (≈21 µg/kg) per injection
Frequency: Once daily for 1–4 consecutive days (duration varied across studies)
Reconstitution Specifications:
– Use the full 3 mL (maximum vial capacity)
– Results in ~3.33 mg/mL concentration
– Each 1 unit on a 100-unit insulin syringe ≈ 33 µg DSIP
Dosage Table (Per Body Weight)
| Body Weight | Dosage (per injection) | Units (per injection) |

| 50 kg | ~1,061 µg (1.061 mg) | 32 units (0.32 mL) |
| 60 kg | ~1,273 µg (1.273 mg) | 38 units (0.38 mL) |
| 70 kg | ~1,485 µg (1.485 mg) | 45 units (0.45 mL) |
| 80 kg | ~1,698 µg (1.698 mg) | 51 units (0.51 mL) |
| 90 kg | ~1,910 µg (1.910 mg) | 57 units (0.57 mL) |
| 100 kg | ~2,122 µg (2.122 mg) | 64 units (0.64 mL) |
Reconstitution Instructions
Basic Steps:
1. Draw 3.0 mL bacteriostatic water with a sterile syringe
2. Inject slowly down the vial wall to minimize foaming (do not shake)
3. Gently swirl until dissolved and protect from light
4. Refrigerate the reconstituted solution at 2–8 °C
5. Avoid repeated freeze–thaw cycles
Storage Guidelines
Lyophilized Form:
– Store at ≤−20 °C in a dry, dark environment
– Minimize moisture exposure
Reconstituted Solution:
– Refrigerate at 2–8 °C
– Use aliquots to avoid repeated freeze–thaw cycles
– Protect from light and limit air exposure
Supplies Needed
Peptide Vial Planning:
– 1–4 doses ≈ 1 vial
– 5–8 doses ≈ 1–2 vials
– 9–12 doses ≈ 2 vials
Additional Materials:
– Insulin syringes (one per injection plus spares)
– Bacteriostatic water (1× 30 mL)
– Alcohol swabs (1 box)
Potential Effects & Safety Profile
Reported Research Outcomes:
Clinical trials documented variable findings. Some studies indicated improvements in sleep parameters, while others found limited clinical significance. “Overall tolerability was generally described as good in short-term studies.”
Notable Observations:
– Changes in total sleep time, sleep latency, awakenings, and sleep efficiency
– Possible short-term benefits with modest and inconsistent effects
– Few adverse effects reported in short-term use
– Limited rigorous long-term safety data
Injection Technique
General Guidelines:
– Clean vial stopper and skin with alcohol swab
– Use fine-gauge insulin syringes
– Inject slowly and rotate injection sites (abdomen, thigh)
– Dispose of sharps safely after each injection
– Maintain consistency in timing (daily at the same time) for standardized observations
Pharmacological Background
Blood-Brain Penetration:
Research in animal models has demonstrated that radiolabeled DSIP crosses the blood–brain barrier and blood-CSF barrier, supporting its potential central nervous system activity.
Mechanism of Interest:
The peptide has been explored for modulation of EEG patterns associated with deep sleep stages and potential interactions with stress-related neuroendocrine axes.
Lifestyle Considerations for Sleep Research
Supporting Factors:
– Maintain regular sleep/wake times and a dark, quiet sleep environment
– Limit stimulants late in the day and manage evening light exposure
– Support sleep quality with balanced nutrition, stress management, and regular physical activity (not close to bedtime)
Important Notes
– Use new, sterile syringes and rotate injection sites when applicable
– Document weight, dose (µg/kg), units, time of day, and observed sleep metrics
– Monitor for unexpected reactions and discontinue if adverse effects occur
– Discuss any concerns with a qualified healthcare professional
