WHAT IS DSIP (DELTA SLEEP INDUCING PEPTIDE)?

Detailed overview

DSIP is a 9-aa peptide first isolated from rabbit brain; human studies report anxiolytic and stress-tolerance effects, with mixed evidence for sleep induction.

Sleep quality

Deep-sleep (N3) phases lengthen, critical for GH release and memory consolidation. The cortisol rhythm normalizes: evening levels drop, morning rise returns. Sleep onset is faster, waking is more rested. GABAergic and serotonergic modulation reduces anxiety, dreams can become more vivid. Over time, symptoms of chronic sleep debt (memory, mood, immunity) improve. Best paired with an afternoon / evening dose.

Research indications

Investigated uses and mechanisms

Sleep architecture

Lengthens deep-sleep phases; refines REM distribution.

Stress / HPA axis

Cortisol rhythm normalizes; evening relaxation supported.

Reconstitution

How to prepare, step by step

Important

Sterile technique required. Use bacteriostatic water (BAC) only. Never distilled or tap water.

  1. 01

    Remove the vial and bacteriostatic water (BAC) from refrigeration; let them reach room temp for 5 minutes.

  2. 02

    Wipe both vial stoppers with an alcohol swab.

  3. 03

    Draw 2 ml of BAC water into a sterile syringe (typical for the 5 mg vial).

  4. 04

    Inject slowly down the side of the vial, do NOT spray directly onto the peptide powder.

  5. 05

    Swirl gently in a circular motion until dissolved (~30 s), do not shake.

  6. 06

    Wait for the solution to become clear. If sediment or discoloration appears, discard it.

  7. 07

    Label the vial with reconstitution date and concentration.

  8. 08

    Store at 2–8 °C, protected from light. Inspect visually before each use.

Quality indicators

How to recognize a pure peptide

Purity markers

3

  • Clear oil

    Clear or slightly yellow (MCT/sesame/castor oil), particle-free.

  • Vial integrity

    Glass intact, rubber stopper undamaged, aluminum crimp tight.

  • Label + COA

    Manufacturer + LOT + expiry legible; independent HPLC analysis on active content.

Use caution

1

  • BA/BB carrier blend

    Excessive benzyl alcohol (>3%) raises PIP risk; verify with UGL manufacturers.

Do not use

2

  • Cloudiness / sediment

    Floating particles, cloudiness, or sediment = HARD NO.

  • Damaged glass / stopper

    Cracked vial or loose stopper, sterility compromised.

Interactions & stacks

What to combine and what to avoid

Selank

Synergistic

Tuftsin analog, anxiolytic nootropic

Adalank (NA Selank Amidate)

Synergistic

Stabilised Selank, anxiolytic + nootropic

Magnesium

Synergistic

GABA support + deeper sleep.

Vitamin C / Zinc / B-complex

Synergistic

Supports collagen synthesis and antioxidant capacity.

Melatonin

Compatible

Different mechanism, combinable.

Caffeine

Requires timing

Compatible with morning dosing; avoid late-day stacking.

NSAIDs (Ibuprofen, ASA)

Use caution

Long-term concurrent use may blunt regenerative effects.

Alcohol

Avoid

Reduces recovery and increases side-effect risk.
