A side-by-side research comparison of DPT and MDMA across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | DPT | MDMA |
|---|---|---|
| Full name | N,N-Dipropyltryptamine | 3,4-Methylenedioxymethamphetamine |
| Category | Psychedelics | Psychedelics |
| Status | Schedule I (research compound) | Schedule I (FDA Breakthrough Therapy for PTSD) |

| Molecular weight | 244.38 g/mol | 193.25 g/mol |
| Half-life | Short | ~7-9 hours |

| Frequency | Occasional | A small number of monthly sessions |
| Route | Oral | Oral, in a supervised therapeutic setting |
