Apigenin vs CPC-1598
A side-by-side research comparison of Apigenin and CPC-1598 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Apigenin | CPC-1598 |
|---|---|---|
| Full name | Apigenin (Flavone) | CPC-1598 (GABAergic Sleep Peptide Analog) |
| Category | Sleep & Recovery | Sleep & Recovery |
| Status | OTC supplement | Research compound |
| Mechanism | Binds benzodiazepine sites on GABA-A receptors for mild anxiolytic and sedative effects, and inhibits CD38, an NAD-consuming enzyme, thereby helping preserve cellular NAD+ levels. Also provides antioxidant and anti-inflammatory activity. | Selectively potentiates a3/a5-containing GABA-A subtypes in sleep-promoting VLPO neurons rather than broadly sedating. Promotes natural sleep onset without respiratory depression. |
| Molecular weight | 270.24 Da | ~650 Da |
| Half-life | ~5-10 hours | 3-5 hours |
| Bioavailability | Low; enhanced by fat and formulation | Moderate (SubQ) |
| Typical dose | 50 mg per day | 200-500 mcg |
| Frequency | Once daily (evening) | Once before bed |
| Route | Oral capsule | Subcutaneous |
