Deep Sleep Stack

Sleep

Components

DSIPLimited evidence EpitalonLimited evidence GlycineModerate evidence

Rationale

A three-pronged sleep approach: DSIP (delta-sleep peptide, deep-sleep architecture), Epitalon (melatonin/circadian resynchronization), glycine (lower core temperature, faster sleep onset). The goal is quality, not sedation.

Evidence level

Glycine has small RCTs on sleep quality; DSIP and Epitalon have older Russian/European studies of mixed quality. The combination is untested.

Caution

DSIP effects are unpredictable (nothing for some, daytime sleepiness for others); do not combine with sedatives.
