Beta-D (3,4,5-trimethoxy-β-dideuterophenethylamine) is a lesser-known psychedelic drug.

It is one of the few phenethylamines used as a recreational drug that is enriched in deuterium.

In his book PiHKAL, the dosage is listed as approximately 200–400 mg for the sulfate salt, and 178–356 mg for the hydrochloride salt.

It produces an increased appreciation of music and a strong connection with God.

[1] Very little data exists about the pharmacological properties, metabolism, and toxicity of Beta-D.
