CPC-1598 vs DSIP
A side-by-side research comparison of CPC-1598 and DSIP across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | CPC-1598 | DSIP |
|---|---|---|
| Full name | CPC-1598 (GABAergic Sleep Peptide Analog) | Delta Sleep-Inducing Peptide |
| Category | Sleep & Recovery | Sleep & Recovery |
| Status | Research compound | Research compound |
| Mechanism | Selectively potentiates a3/a5-containing GABA-A subtypes in sleep-promoting VLPO neurons rather than broadly sedating. Promotes natural sleep onset without respiratory depression. | Modulates GABAergic and glutamatergic neurotransmission in sleep nuclei. Enhances delta wave NREM sleep, normalizes circadian patterns, and reduces cortisol/CRH during sleep. |
| Molecular weight | ~650 Da | 849 Da |
| Half-life | 3-5 hours | 7-8 minutes |
| Bioavailability | Moderate (SubQ) | Low (rapid peptidase degradation) |
| Typical dose | 200-500 mcg | 100-300 mcg |
| Frequency | Once before bed | Once, ~30-60 min before bed |
| Route | Subcutaneous | Subcutaneous injection |
