Question 1

What is DSIP?

Accepted Answer

Delta sleep-inducing peptide, a nine-amino-acid neuromodulator isolated in 1977 from the cerebral venous blood of rabbits during slow-wave sleep.

Question 2

Does it work like a sedative?

Accepted Answer

No. The literature describes it as shifting the distribution of sleep stages rather than inducing sleep, which is a different kind of effect.

Question 3

What receptor does it bind?

Accepted Answer

None has been identified, despite nearly fifty years of study. That gap is one of the more notable features of the DSIP literature.

Question 4

How good is the human evidence?

Accepted Answer

Consistent in direction but limited: small, mostly older studies, largely uncontrolled. The preclinical work is stronger.

Question 5

Does it reach the brain?

Accepted Answer

Published work reports that it crosses the blood–brain barrier, which is itself unexplained since it carries no recognised transport motif.

Question 6

What documentation comes with it?

Accepted Answer

A batch certificate of analysis with HPLC purity, linked on this page and verifiable on the testing laboratory's site.
