I disagree totally.
I did 1gram of MDAT a few nights ago, and a few doses of naphyrone and half a g of what was "meant" to be 5-iai (but clearly was not).
The first 6-7 hours were amazing, just like oldskool messy beans - tingly spine, everything was hard to concentrate on, very active but not overwhelming and no harsh OTT heart rate. I would liken it to a combination of a strong MDA dose (or 5 or 6 oldskool pills), with a slight mescaline/2ce edge. Very impressive in my opinion. Best way to take IMHO is to tongue it, rub the crystals on your tongue till they dissolve slightly and wash it down.
In hindsight, the whole gram was a bit too much and lasted tooooo long, probably not helped by the naphyrone at the end, but I would highly recommend a 200mg oral dose.... took me back many years

)
A few follow up points....
It it was FAR FAR stronger than any MDAI experiance - I would not even place them on the same spectrum. Doing a gram in a short time not a good idea - and no it was not poor quality, it was as it should be- a light brown/fake tan coloured/somewhat transparent mostly very large crystalised compound with a slightly bitter-sweet almost ciitrusy alcohol taste. The only annoying aspect is that in high doses it's too trippy. I would not agree at all with the person who said about the "collapse threshold." However, I would say the compound (and appreciation of some of my comments) are probably for somewhat more experienced researchers. Possibly due to the high dose in one go, but I can understand how someone could become overwhelmed if had not experienced high doses of similarly available or now illegal compounds before. Best not to mix it with naphyrone though - it began to piss me off after about 40 hours whilst at work. The pleasant MDAT effects were still present but being extended and overshadowed. Also insufflicating is definately not the way to do with this, annoyingly as it is by far my most preferred method of research.... not because of the pain aspect at all with this - but the full effects of MDAT are far more prevalent and appreciable with oral methods.
Points worth mentioning..... at high doses easy to be drawn into the "mirror" syndrome just as with most of the 2C's. Not good on the stomach/digestive system - especially the day after. HIGHLY heightened sense of smell and to a lesser extent sound. Quite ludicrous tracers... and colour amplification especially with reds and greens. Very occasionally disturbingly dark visuals and nightmare stlye facial patterns, but easily dealt with if you don't concentrate on them for long (hence the 2ce reference.) And lastly, and quite bizarrely for ANY such compound of this style I have experienced before - a underlying but very noticeable sense of hunger throughout the experience once the full effects are upon you (quite like after a few hefty herbal fags!,) up but never actually being able to concentrate on it long enough to act upon it.
All in all - something very interesting. Got that very sensual MDMA feeling at peak.... Lots to think about - not much to worry about in terms of harm/OD/abuse I personally would say, especially with today's RC situation. For people new to such compounds I would imagine very enlightening compared to drone habituals etc and people experienced in the research of PURELY stims, but don't OVER estimate the dose for MDAT... you need a good whack of this stuff to really appreciate it and it's well worth it when you do.
Lastly... a few beers before hand a good idea but don't drink too much (alcohol) whilst on it.... nothing to do with dehydration issues although obviously keeping yourself watered is a fair idea; but it tends to dull out the effects. A few 5HTP before and after not a bad idea.
Hope this is of some use.
Peace.
