Sleep & Circadian

DSIP

Also known as: Delta Sleep-Inducing Peptide, Emideltide

Delta sleep-inducing nonapeptide taken for sleep quality, dosed a few hours before bed on an empty stomach. Effect is inconsistent (human replication has largely failed) and the therapeutic window is narrow, so higher doses can backfire.
