DSIP vs Melatonin
A side-by-side research comparison of DSIP and Melatonin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | DSIP | Melatonin |
|---|---|---|
| Full name | Delta Sleep-Inducing Peptide | Melatonin (N-Acetyl-5-Methoxytryptamine) |
| Category | Sleep & Recovery | Sleep & Recovery |
| Status | Research compound | OTC supplement / hormone |
| Mechanism | Modulates GABAergic and glutamatergic neurotransmission in sleep nuclei. Enhances delta wave NREM sleep, normalizes circadian patterns, and reduces cortisol/CRH during sleep. | Produced by the pineal gland in response to darkness, melatonin binds MT1/MT2 receptors to promote sleep onset and shift circadian timing. It also acts as a direct free-radical scavenger and supports mitochondrial antioxidant defenses. |
| Molecular weight | 849 Da | 232.28 Da |
| Half-life | 7-8 minutes | ~40-60 minutes (immediate release) |
| Bioavailability | Low (rapid peptidase degradation) | Low and variable oral (~15%); sublingual improves onset |
| Typical dose | 100-300 mcg | 0.3-5 mg before bed |
| Frequency | Once, ~30-60 min before bed | Once nightly |
| Route | Subcutaneous injection | Oral or sublingual |
