DSIP

A short peptide studied for deep sleep and stress hormone balance.

What it is

DSIP is a nine amino acid peptide first isolated from rabbit brain during sleep research in the 1970s.

How it works

Research reports increased delta wave sleep, the deep stage tied to physical recovery, along with effects on cortisol and pain perception. The exact mechanism is still unclear.

What it is researched for

• Deep sleep quality
• Stress and cortisol rhythm
• Chronic pain research

Research status

Old research base, limited modern human trials. Research use only.

What to watch for

• Grogginess the next morning at higher doses
• Inconsistent user reports on effectiveness

Storage

Lyophilised powder keeps in the freezer or fridge, away from light. Once reconstituted with bacteriostatic water, keep it refrigerated and use it within about four weeks.

Common questions

Is it a sedative?

It is not described as sedating. Reports focus on sleep depth rather than falling asleep faster.

Can it be taken every night?

Most protocols cycle it a few nights a week to avoid diminishing returns.
