- | Compound Class | Primary Mechanism | Slow-Wave Sleep Impact | REM Sleep Impact | Tolerance Development | Cortisol Suppression | Professional Assessment ||—|—|—|—|—|—|| DSIP (Delta Sleep-Inducing Peptide) | GABAergic modulation + HPA axis suppression | +20–35% increase | No suppression | None observed | Yes (28% evening reduction) | Addresses root hormonal and autonomic causes. Restores architecture rather than forcing unconsciousness || Benzodiazepines (e.g., temazepam) | Direct GABA-A receptor agonism | −30–50% reduction | −15–25% suppression | 14–21 days | No | Forces sedation but degrades restorative sleep quality. Tolerance is inevitable || Z-Drugs (e.g., zolpidem) | Selective GABA-A α1 subunit agonism | −20–40% reduction | Minimal suppression | 28–35 days | No | Faster tolerance than benzodiazepines but same architectural degradation || Melatonin | Circadian timing signal (MT1/MT2 receptors) | No direct effect | No suppression | None | No | Effective for circadian misalignment.
- The comparison makes the distinction clear: DSIP is the only compound in this table that increases slow-wave sleep, suppresses cortisol, and avoids tolerance. Benzodiazepines and Z-drugs trade immediate sedation for degraded sleep quality and dependence risk. Melatonin works beautifully for jet lag and shift work. But if your insomnia is cortisol-driven, melatonin won't touch it.
