Shulgin's TiHKAL synthesis #17.
4-HO-DIPT.

4-HYDROXY-N,N-DIISOPROPYL-TRYPTAMINE
DOSAGE : 15 - 20 mg, orally.
DURATION : 2 - 3 h.
COMMENTARY:I truly doubt that there is another psychedelic drug, anywhere, that can match this one for speed, for intensity, for brevity, and sensitive
to dose, at least one that is active orally. These reports have been taken from different experimenters, but they share some rather consistent features.
