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.

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.
- 01
Remove the vial and bacteriostatic water (BAC) from refrigeration; let them reach room temp for 5 minutes.
- 02
Wipe both vial stoppers with an alcohol swab.
- 03
Draw 2 ml of BAC water into a sterile syringe (typical for the 5 mg vial).
- 04
Inject slowly down the side of the vial, do NOT spray directly onto the peptide powder.
- 05
Swirl gently in a circular motion until dissolved (~30 s), do not shake.
- 06
Wait for the solution to become clear. If sediment or discoloration appears, discard it.
- 07
Label the vial with reconstitution date and concentration.
- 08
Store at 2–8 °C, protected from light. Inspect visually before each use.
