Piperazines are like chemical versions of SPAM. Enough said.
There is a definite difference between MDA and MDMA, In my experiments back in the day, most people cannot tell the difference, but can be taught to tell the difference.....as noted, MDMA is transformed into MDA via a demthylation enzyme in the liver, ~ 7-10% of mdma is changed....so, as time goes by, one will find that the effects get more profound as one continues.
There is not a lot of literature available, even today, on the subtle shades of psychic states attained by what I have come to think of as 'Marathon sessions' on either of these compounds.
There IS a LOT more there than empty hallucinations, but I feel that
MDMA or MDA reveals more to a person if they are the type of person who already is at a certain level.......what I am trying to say is that for myself, I was already 'opened' by LSD and psilocybin by the time I got in the X game, and I found BOTH MDA and MDMA to be absoutely VISIONARY substances, but that may be my peculiar fate.
Shulgin doesn't elaborate on extended tours on either of these, but I have done both of them, separately and mixed, for days on end....
there is another 'vibe' you tune into, I guess, is a way of thinking about it.
When I do MDA, it is like getting ran over by a truck when it first comes on. The weight and gravity of it is immense.....it is, primarily an intoxication, a debilitating one. I once took 300 mg of MDA on an empty stomach, after fasting for about 30 hours. The MDA was ultra-pure, in a capsule....when it hit me, I couldn't stand up for two hours.
MDMA feels like an orgasm happening, to me, personally. It is the greatest feeling in the world....well, there are a few others right up there, but it is one of the best, surely.
One time, I was in a grocery store @ 8 am on a Sunday morning in a small country town in the deep south, I had been doing MDA since about three o'clock the previous day and I was pleasantly inebriated.
Colors were heightened, and I was immersed in my own little world.
I was pushing the cart down the aisle and saw a woman picking up a can. I noticed that she had an expression on her face, and without thinking about it I realized, 'she's worried'......I shook it off and moved on....I began noticing, as I moved throught the store, that I could glance at a person and get a 'read' on their emotional state instantly.
Of course, this is something we all do automatically anyway, but it was amplified almost to the degree of telepathy. I found facial features to be exaggerated and to posess too much information.
The last time I did MDA I got these huge, temple-like structures that went WAAAYYY up into the sky, and it had a very mescaline like aspect to it....I thought I was in the desert a couple of times....
but I was in my front yard.
