The last couple of weeks, a good handful of experienced, wellinformed people have tasted the compound at different levels. It seems like 4,5 mg is about as high as most people like to go. In the area 4-4,5 mg, everyone have had a satisfying and fulfilling psychedelic experience.
I tasted 4,5 mg myself this weekend. It comes on much faster than DOB; a definate ~+1,5 after an hour. I would say the peak is about 3,5 hours after ingestion (when ingested in solution). I think the level of stimulation will prevent us from taking much higher doses than 4,5 mg. Not that it felt uncomfortable or dangerous at all, but a slight hypertension was noticed. Mentally, the trip is quite easy to manage. No real confusion, and if you feel like it, you can bring yourself "back to reality" without much effort.
The visuals are not really that impressive. As expected, much more like 2C-B or mescaline than acid. Beautiful and fun, but not overwhelming. The mind is racing in entertaining directions, and the experience is quite humorous to most test-pilots.
No adverse effects have been noticed the day after the trip. During the trip, some people get a slight bit of nausea, but the it seems like it is rarer (and less uncomfortable) on this compound than on 2C-B.
BTW, the yield from the 2,3 g of DMA was about 1,5 g. We don't know for sure yet, since only half of it has been purified.
