1,3,5-Trimethoxyamphetamine or TMA-6 is psychedelic amphetamine. It is most closely related to mescaline, found in peyote, but has an alpha-methyl increasing potency and duration and a rearrangement of the methoxy groups on the ring.
It is a long-lived psychedelic with a duration between 12 and 16 hours taken orally, according to Shulgin. This is as expected due to the metabolic blockade provided by the ring substitutions and the a-methyl group. The oral dose is supposedly between 30 and 60 mg. Vaporised doses are typically 50-75% lower.
I returned one balmy afternoon to find a had some spare time and decided to attempt vaporising it. Vaporising allows superb dose control because of its fast onset, so you can easily decide when you have reached an acceptable level of intensity. It also offers a reduction in duration compared to oral of between /3 and 1/4. Substances with a longer duration are typically reduced less.
It is a beige-yellow solid. I had previously attempted and a/b extraction but this failed to remove the discolouration. there is a faint but pleasant essential oil type smell to it, perhaps from the alkene or aldehyde. the melting point is quoted as being high and this is corroborated by the fact that it takes a while to begin evaporating and burns slightly.
I loaded 26mg of the freebase into the vaporiser dissolved in 40% ethanol. I vape everything over about 20 minutes, noting that the larger breaths are quite unpleasant. I reach perhaps a 3/10, and although music sounds better there is no mood lift and no other strong effects. I load another 7mg and after trying for a bit decide I don’t really like it and wish I hadn’t bothered. My vision is almost cloudy, in a hard to describe manner.
I decide to re-read what Shulgin had to say on the matter. Upon remembering his experiences were high positive I am reassured that mine can be the same and I begin to enter a new frame full of cheer – the ever present importance of set and setting!
I move into some mild nausea which is not helped by eating, moving or being still. It is quite mild and easily ignored as I enjoy listening to music and going about my afternoon it fades to nothing within a few hours.
I have a think about where I am after about 2 hours and decide that I was probably more like a 4 before and am only now at a 3. The experience remains very pleasant, winding down very slowly. After 9 hours I am still around 2/10 and decide to have some weed to sleep. This brings on mild but colourful visuals and I am soon able to sleep.
Overall the experience was very pleasant and I am very keen to go again when I have the time for a 12 hour trip. Highly recommended.
