DSIP — 10mg protocol. Edit the doses below for the 10mg vial.

Quickstart Highlights

DSIP dosage protocols can help promote deep, restorative delta-wave sleep and support healthy stress response. Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide (9 amino acids) first isolated from rabbit brain for its ability to enhance slow-wave sleep[1]. Research indicates DSIP may improve sleep quality, normalize sleep architecture, reduce stress-related cortisol patterns, and support mood stabilization without next-day grogginess[2][3]. This educational protocol presents a once-daily subcutaneous evening approach using a practical dilution for clear insulin-syringe measurements.

  • Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration.
  • Typical daily range: 100–300 mcg once daily in the evening (gradual titration).
  • Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U-100 insulin syringe.
  • Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Dosing & Reconstitution Guide

Phase Dose Units (per injection)
Week 1 100 mcg 3 units (0.03 mL)
Week 2 150 mcg 5 units (0.05 mL)
Week 3 200 mcg 6 units (0.06 mL)
Weeks 4–8 250–300 mcg 8–9 units (0.08–0.09 mL)


Frequency: Inject once daily subcutaneously in the evening, approximately 30–60 minutes before bedtime[4]. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.

Reconstitution Steps

  1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl/roll until dissolved (do not shake).
  4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–12 week nightly protocol with gradual titration.

  • Peptide Vials (DSIP, 10 mg each):
    • 8 weeks ≈ 1 vial (10 mg supports ~33–100 doses at 100–300 mcg)
    • 12 weeks ≈ 2 vials
  • Insulin Syringes (30- or 50-unit recommended for small volumes):
    • Per week: 7 syringes (1/day)
    • 8 weeks: 56 syringes
    • 12 weeks: 84 syringes
  • Bacteriostatic Water (10 mL bottles): Use 3.0 mL per vial for reconstitution.
    • 8 weeks (1 vial): 3 mL → 1 × 10 mL bottle
    • 12 weeks (2 vials): 6 mL → 1 × 10 mL bottle
  • Alcohol Swabs: One for the vial stopper + one for the injection site each day.
    • Per week: 14 swabs (2/day)
    • 8 weeks: 112 swabs → recommend 2 × 100-count boxes
    • 12 weeks: 168 swabs → recommend 2 × 100-count boxes

Protocol Overview

Protocol Overview

Concise summary of the once-daily evening regimen.

  • Goal: Support improved sleep quality, enhanced delta-wave (slow-wave) sleep, and stress modulation over time[2][3].
  • Schedule: Daily subcutaneous injections in the evening for 8–12 weeks.
  • Dose Range: 100–300 mcg daily with gradual titration.
  • Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.

Dosing Protocol

Suggested nightly titration approach.

  • Start: 100 mcg nightly; increase by ~50 mcg every 1–2 weeks as tolerated.
  • Target: 250–300 mcg nightly by Weeks 4–8.
  • Frequency: Once per day (subcutaneous), 30–60 minutes before bedtime.
  • Cycle Length: 8–12 weeks; consider a break after the cycle.
  • Timing: Evening dosing to align with natural sleep onset; rotate injection sites.

Storage Instructions

Proper storage preserves peptide quality.

  • Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions; minimize moisture exposure[5].
  • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); prepare aliquots if needed and avoid freeze–thaw.
  • Allow vials to reach room temperature before opening to reduce condensation uptake.

How It Works

DSIP (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) was first characterized in 1977 as a sleep-modulating factor isolated from rabbit brain[1]. Mechanistic studies suggest DSIP may influence sleep by modulating GABAergic transmission and interacting with opioid receptor systems[10]. Research indicates it can increase delta-wave (slow-wave) sleep duration without significantly altering REM sleep architecture[3]. Beyond sleep, DSIP has demonstrated stress-protective and adaptogenic properties in various models, potentially through modulation of the hypothalamic-pituitary-adrenal axis[4][11].

Important Notes

Practical considerations for consistency and safety.

  • Use new sterile insulin syringes; dispose in a sharps container.
  • Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation[6].
  • Inject slowly; wait a few seconds before withdrawing the needle.
  • Document daily dose and site rotation to maintain consistency.
  • Avoid other sedatives during DSIP use to clearly evaluate its effects on sleep.

Potential Benefits & Side Effects

Observations from preclinical and clinical literature.

  • Supports improved sleep quality and increased slow-wave (delta) sleep duration[2][3].
  • May help normalize disrupted sleep patterns in chronic insomnia[3].
  • Shows potential for stress reduction and mood support through HPA axis modulation[8][9].
  • Remarkably safe profile: animal studies found no lethal dose even at extremely high doses; human studies report only mild, transient side effects (occasional headache or nausea)[1][8].
  • Occasional mild injection-site reactions (redness/itch) may occur with subcutaneous administration.

Lifestyle Factors

Complementary strategies for best outcomes.

  • Maintain consistent sleep-wake schedules to reinforce circadian rhythm.
  • Limit caffeine and screen exposure in the evening hours.
  • Create a dark, cool sleep environment to support natural melatonin production.
  • Prioritize stress management techniques and regular physical activity during daytime hours.
