Research Evidence Comparison# DSIP Research# DSIP research peaked in the 1980s-1990s and has largely stalled: Schneider-Helmert (1987) : Reported acute sleep-inducing effects of IV DSIP in normal subjects, with sleep increased 59% within a 130-minute observation window Schneider-Helmert & Schoenenberger (1992) : Double-blind study in chronic insomniacs showed DSIP improved sleep efficiency, but sample size was small 2024 fusion peptide study : Frontiers in Pharmacology published research on DSIP-BBB fusion peptides in insomnia mouse models, representing renewed interest in the peptide No Phase 2 or Phase 3 data : DSIP has never undergone modern regulatory-quality clinical trials Evidence level : Low -- small studies from the 1980s-1990s, no modern RCTs
