A lesser-known psychedelic drug is 4-HO-MET (4-hydroxy-N-methyl-N-ethyltryptamine, or metocin, methylcybin, colour). It is both a structural and functional analog of psilocin and MET’s 4-hydroxyl analog. Alexander Shulgin first synthesized 4-HO-MET. The dosage is described as 10-20 mg in his book TiHKAL (Tryptamines I Have Known and Loved). 4-HO-MET creates psilocin-like color, tone, and shape distortion. There is very little evidence on 4-HO-pharmacological MET’s properties, metabolism, and toxicity. No cases of 4-HO-MET deaths have been reported, although people have reported taking doses of up to 150 mg, more than the order of magnitude above the effective dose.
