F-2, or 6-(2-amino propyl)-5-methoxy-2-methyl-2,3-dihydrobenzofuran, is a lesser-known psychedelic drug. F-2 was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 15 mg, and the duration unknown. F-2 produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of F-2.
