What is "thioproscaline"

Thioproscaline, or 3,5-di methoxy-4- propyl thio phenethylamine, is a lesser-known psychedelic drug. It is the 4- propyl thio analog of mescaline. Thioproscaline was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 20–25 mg, and the duration listed as 10–15 hours. Thioproscaline causes closed-eye visuals, slight open-eye visuals, and a body load. Very little data exists about the pharmacological properties, metabolism, and toxicity of thioproscaline.
