Protocol

50-100mcg SubQ or intranasal before bed. Some use up to 250mcg.

Time to effects

EARLY: 1-3 nights

FULL: 2-4 weeks

Night 1-3: Improved sleep onset and depth. Many notice better sleep quality from the first dose.

Week 1-2: Normalised sleep architecture. More consistent deep sleep. Less nighttime waking.

Week 2-4: Cumulative effects — improved daytime energy from better sleep. Stress recovery improved.

Effects on sleep are felt quickly. Unlike sedatives, DSIP improves sleep QUALITY rather than just knocking you out. Minimum commitment: 2 weeks.

Recommended vial
  • 5mg vials

At 100mcg/night = 50 days ⚠️ exceeds 3-4 wk shelf life. At 250mcg/night = 20 days ✓. Use higher dosing. 10mg = much worse.
