5-MeO-pyr-T, or 5-methoxy-N,N-tetramethylenetryptamine, is a lesser-known psychedelic drug. It is the 5-methoxy analog of pyr-T. 5-MeO-pyr-T was first synthesized by Alexander Shulgin. In his book TiHKAL (Tryptamines I Have Known and Loved), neither the dosage nor the duration are known. 5-MeO-pyr-T causes tinnitus, vomiting, and a 5-MeO-DMT-like rushing sensation. At the highest dosage reported in TiHKAL, the subject describes awakening from an apparent fugue state in which they were wandering the streets, with complete amnesia upon awakening of what they had been doing. This suggests that 5-MeO-pyr-T could cause potentially hazardous random behavior at high doses. Very little data exists about the pharmacological properties, metabolism, and toxicity of 5-MeO-pyr-T.
