TOMSO
Overview
TOMSO, or 5-TOMSO, also known as 2-methoxy-4-methyl-5-methylsulfinylamphetamine, is a psychedelic drug of the phenethylamine and amphetamine families related to the DOx series. It is the analogue of DOM in which the methoxy group at the 5 position has been replaced with a sulfur-containing methylsulfinyl group.[1]
In his book PiHKAL (Phenethylamines I Have Known and Loved), Alexander Shulgin lists TOMSO's dose as >150 mg orally alone or 100 to 150 mg orally in combination with alcohol and its duration as 10 to 16 hours. TOMSO was reported to produce no or only threshold effects by itself at the assessed doses, but when alcohol was concomitantly ingested, clear hallucinogenic effects occurred. These effects included facial distortion and remarkable time dilation, among others. When combined with alcohol, "plus-two" and "plus-three" experiences occurred on the Shulgin Rating Scale.[1] WP
The chemical synthesis of TOMSO has been described.[1] WP
TOMSO was first described in the scientific literature by Alexander Shulgin and Peyton Jacob III in 1983. Subsequently, it was described in greater detail by Shulgin in PiHKAL in 1991.[1]

Harm reduction information
No harm reduction data is on file for this compound yet. That means no dose, timing or combination data from PsychonautWiki or TripSit. Please don't guess a dose from similar compounds. If you have taken it and feel unwell, contact emergency services or a poison control center.
Shulgin notes
These figures come from the Shulgins' own small trials, published decades ago. They are history, not a dosing guide: they were never checked the way a harm reduction dose table is, and batches, purity and people differ.
TOMSO dose is >150 mg alone or 100–150 mg with alcohol. WP
