Beatrice, MDO-D, MDOM, or 4-methyl-2,5-dimethoxymethamphetamine, is a lesser-known psychedelic drug. It is an analog of Methamphetamine and a homolog of DOM. Beatrice was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 30 mg, and the duration listed as 6–10 hours. Beatrice produces a vague feeling of openness and receptiveness, and causes a stimulative effect. It also causes diarrhea. Very little data exists about the pharmacological properties, metabolism, and toxicity of Beatrice.
