Bottom line

Read Off Label grades DSIP (delta sleep-inducing peptide) as C+ (5.7/10) based on weak evidence, variable benefit magnitude, and a low-risk safety profile.

First characterized Monnier 1977.

Typical use: 100-500 mcg subQ at night (anecdotal) — Research peptide.

What this is

First characterized Monnier 1977. Despite the name, not reliably sleep-inducing in controlled studies. Popular in peptide community for sleep/recovery; evidence is thin. Short plasma half-life.

Mechanism

Nonapeptide isolated from rabbit brain dialysate during delta sleep; proposed sleep modulatory and stress-protective effects; mechanism unclear

Dose & route

100-500 mcg subQ at night (anecdotal)
