Quickstart Highlights

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (9 amino acids) first isolated from rabbit brain tissue and studied for its proposed effects on sleep architecture and stress modulation[1][2]. This educational page outlines a once-daily subcutaneous approach with a dilution chosen so doses land on easy-to-read insulin-syringe marks. DSIP is an unapproved research chemical — never approved by the FDA or EMA for any indication; human evidence is limited and dated, with no standardized dosing established. Presented for research and educational use only.

Add 3.0 mL bacteriostatic water to one 5 mg vial → ~1.67 mg/mL (1,667 mcg/mL), a practical dilution for accurate dosing.
100–300 mcg once daily with gradual titration; advanced use up to 500 mcg.
At ~1.67 mg/mL, 1 unit = 0.01 mL ≈ 16.7 mcg on a U-100 insulin syringe.
Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and avoid freeze–thaw cycles.
Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.

Dosing & Reconstitution Guide

A single practical dilution with accurate once-daily dosing, step by step

Standard / Gradual Approach (3 mL = ~1.67 mg/mL)

Phase / Week(s)	Daily Dose (mcg)	Volume (U-100 units / mL)
Week 1	100 mcg (1× daily)	6 units (0.06 mL)
Week 2	150 mcg (1× daily)	9 units (0.09 mL)
Week 3	200 mcg (1× daily)	12 units (0.12 mL)
Weeks 4–8	250–300 mcg (1× daily)	15–18 units (0.15–0.18 mL)

Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 mcg/mL).
Typical daily range: 100–300 mcg once daily with gradual titration; advanced use up to 500 mcg.
Easy measuring: At ~1.67 mg/mL, 1 unit = 0.01 mL ≈ 16.7 mcg on a U-100 syringe.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and avoid freeze–thaw cycles.
Frequency: one subcutaneous injection each day, typically in the evening before bedtime, titrating up gradually as tolerated[5][6]. Advanced users may extend toward a ceiling of 500 mcg (30 units, 0.30 mL). These figures come from limited reference literature, not from approved human dosing.

Reconstitution Steps

Draw 3.0 mL of bacteriostatic water into a sterile syringe.

Release it slowly down the vial’s inner wall to limit foaming.
Swirl or roll gently until fully dissolved — don’t shake.
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
For low-volume doses (≤10 units / ≤0.10 mL in Weeks 1–2), a 30- or 50-unit insulin syringe improves readability. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.

12 weeks at ~300 mcg/day: ~5–6 vials
Per week: 7 syringes (1/day)
8 weeks: ~56 syringes
12 weeks: ~84 syringes
Use ~3.0 mL per 5 mg vial for reconstitution.
3 vials (9 mL): 1 bottle
5 vials (15 mL): 2 bottles
6 vials (18 mL): 2 bottles
One for the vial stopper + one for the injection site each day.
Per week: 14 swabs (2/day)
8 weeks: ~112 swabs → 2 boxes
12 weeks: ~168 swabs → 2 boxes

Protocol Overview

A concise summary of the once-daily regimen, drawn from the limited reference literature.

▪Goal: Studied for its proposed support of slow-wave (delta) sleep and stress/neuroendocrine modulation — effects described in research but not established in approved clinical use[3][4].
▪Schedule: Daily subcutaneous injections for 4–8 weeks, optionally extended to ~12 weeks with periodic breaks.
▪Dose Range: 100–300 mcg daily with gradual titration; advanced up to 500 mcg.
▪Reconstitution: 3.0 mL bacteriostatic water per 5 mg vial gives ~1.67 mg/mL for accurate unit measurements.
▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and avoid repeated freeze–thaw.

Dosing Protocol

A suggested daily titration approach based on common reference doses.

▪Start: Begin at 100 mcg once daily; increase by ~50 mcg every 1–2 weeks as tolerated.
▪Target: Reach about 250–300 mcg daily by Weeks 4–8.
▪Frequency: Once per day subcutaneously, typically before bedtime.
▪Cycle Length: Typically 4–8 weeks; optional extension to 12 weeks with periodic breaks.
▪Timing: Evening administration preferred; rotate injection sites systematically.

Storage Instructions

Correct storage is what preserves the peptide’s stability and activity.

▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[7].
▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 4 weeks; avoid freeze–thaw, as freezing can denature peptides[8].
▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
▪Freeze–thaw: Avoid repeated freeze–thaw cycles of the reconstituted solution.

Important Notes

Practical points that keep daily administration safe and consistent.

▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[9].
▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
▪Regulatory note: DSIP is not approved by the FDA or EMA for any indication — it is an unapproved research chemical with no established safety profile[6].

How This Works

DSIP (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) is a naturally occurring nonapeptide (9 amino acids) first characterized in 1977 as a sleep-modulating factor isolated from rabbit brain[1].

No definitive receptor or pathway has been mapped for DSIP. Mechanistic studies propose that it may influence sleep through interactions with GABAergic and opioid systems, but these neurotransmitter interactions remain unconfirmed[10]. Some research describes increased delta-wave (slow-wave) sleep duration without major changes to REM architecture[3].
Beyond sleep, DSIP has been studied for proposed stress-protective and adaptogenic properties, potentially through modulation of the hypothalamic-pituitary-adrenal (cortisol/ACTH) axis[4][11]. These remain proposed effects, not confirmed clinical outcomes.
Important caveat: human evidence for DSIP is limited and dated, and decades of study never reached regulatory approval. Effects on sleep, stress, recovery, or longevity should be read as studied or proposed, not proven.
DSIP is not an approved medicine. It is an unapproved research chemical presented here for research and educational purposes only.

Lifestyle Factors

Complementary habits that may support sleep and stress goals alongside the protocol.

▪Sleep schedule: Keep consistent sleep-wake times to reinforce your circadian rhythm.
▪Light & stimulants: Limit blue-light exposure and stimulants (caffeine, nicotine) in the hours before bed.
▪Environment: Create a cool, dark, quiet sleep environment.
▪Activity: Incorporate regular physical activity, ideally earlier in the day.
▪Stress: Manage stress through relaxation techniques such as meditation and deep breathing.

Potential Benefits & Side Effects

Observations from limited and dated preclinical and clinical literature; nothing here is established or approved, and individual results vary.

▪Slow-wave sleep: Some studies report deeper slow-wave sleep and improved subjective sleep quality[3][5].
▪Stress modulation: Research suggests proposed stress-protective and anxiolytic-like effects[4][11].
▪Tolerance: Some studies indicate DSIP does not appear to induce pharmacological tolerance with continued use[2].
▪Note: These effects are not proven — human evidence is limited and dated, with no standardized dosing or approved use.
▪Injection-site reactions: Occasional mild redness, tenderness or soreness may occur with subcutaneous administration; rotating sites helps.
▪Limited safety data: Long-term human safety data is limited; periodic breaks are recommended as a precaution[6].
▪Unapproved: DSIP is not approved by the FDA or EMA and is for research use only — not for human consumption.

Injection Technique

General subcutaneous technique, following established clinical best-practice guidance[12][13].

▪Wash your hands well with soap and water.
▪Wipe the vial stopper with an alcohol swab and let it air-dry.
▪Choose a site (abdomen at least 2 inches from the navel, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[13].
▪Draw the intended dose, then check for air bubbles and push any out.
▪Pinch a skinfold at the chosen site between thumb and forefinger.
▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[12].
▪Skip aspiration for subcutaneous shots — it isn’t needed[12].
▪Press the plunger slowly and steadily until it’s fully down.
▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
▪Return the reconstituted vial to the fridge right away.
▪Rotate the injection site each day to prevent irritation and lipohypertrophy[9].
▪Watch the site for excess redness, swelling, or signs of infection.
