DSIP

Delta Sleep-Inducing Peptide — short nonapeptide isolated from rabbit cerebral blood during sleep.

DSIP was first isolated from the blood of sleeping rabbits — a naturally occurring signal tied to the deep, slow-wave stage of sleep. Rather than knocking you out like a sedative, it seems to nudge sleep architecture toward more restorative deep sleep and helps buffer the body against stress. Response is genuinely variable — some people find it transformative, others feel nothing — so it's worth a short trial to see which camp you fall in. It clears in minutes, but the downstream sleep effect carries through the night.

Dose

100–500 mcg subQ pre-bed.

Reconstitute

10 mg + 2 mL = 5 mg/mL. 4 units = 200 mcg.

Schedule

As-needed or 30-day sleep-reset blocks.

Half-life

~7 minutes (very short, but downstream sleep effects last hours).

Timing

30 minutes before sleep.

Risks

Very mild. Some users feel nothing.
