Comparison table
| Attribute | 2C-B | Psilocybin |
|---|---|---|
| Full name | 4-Bromo-2,5-dimethoxyphenethylamine | Psilocybin (from psilocybin mushrooms) |
| Category | Psychedelics | Psychedelics |
| Status | Schedule I (research compound) | Schedule I (FDA Breakthrough Therapy for depression) |
| Mechanism | Activates serotonin 5-HT2A receptors. A phenethylamine rather than a tryptamine. | Converted in the body to psilocin, which activates serotonin 5-HT2A receptors in the brain. This temporarily loosens rigid thinking patterns and increases connectivity between brain networks. |
| Molecular weight | 260.16 g/mol | 284.25 g/mol |
| Half-life | ~2 hours | ~2-3 hours (psilocin) |
| Bioavailability | Oral | Oral |
| Typical dose | Varies by individual and setting | 10-30 mg in clinical trials |
| Frequency | Occasional | One to a few supervised sessions |
| Route | Oral | Oral, in a supervised therapeutic setting |
