Beta-D, or 3,4,5-tri methoxy-beta-di deutero phenethylamine, is a lesser-known psychedelic drug. It is one of the few phenethylamines used as a recreational drug that is enriched in deuterium. Beta-D can be prepared as a sulfate salt or as a hydrochloride salt. It is the beta-dideutero analog of mescaline. Beta-D was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage is listed as approximately 200-400 mg for the sulfate salt, and 178-356 mg for the hydrochloride salt. Its effects last for 12 hours. Beta-D has a very rapid onset. It produces an increased appreciation of music and a strong connection with God. Very little data exists about the pharmacological properties, metabolism, and toxicity of Beta-D.
