- DSIP
- GABAergic modulation at VLPO; CRF antagonism in PVN
- Increases delta power density 14–19% without altering total sleep time
- ~30 minutes (central clearance)
- Minimal. No receptor downregulation observed in rodent models
- Best for sleep architecture optimization in stress-reactive phenotypes; not a first-line sleep aid
- Epitalon
- Telomerase activation; pineal gland function restoration
- Indirect. Normalizes circadian melatonin secretion, which stabilizes NREM cycling
- 6–8 hours
- None documented
- Addresses age-related sleep fragmentation; mechanism is upstream of DSIP's direct delta modulation
- Selank
- Anxiolytic via serotonergic and GABAergic pathways
- Minimal direct effect on delta waves; improves sleep quality by reducing pre-sleep anxiety
- 20–30 minutes
- Low. No withdrawal or rebound anxiety
- Complementary to DSIP; targets sleep latency and anxiety-driven wakefulness rather than delta depth
- Melatonin
- Chronobiotic. Regulates SCN circadian timing
- Stabilizes sleep-wake timing but doesn't increase delta power
- 20–50 minutes
- None
- Timing tool, not a delta wave enhancer; works synergistically with DSIP in circadian misalignment cases
