My one experience with this compound was probably the worst body-load/unpleasant side affects from the 2c-x's I've tried (c,d,i,t-2). I took a bit too high of a dose for my first time, 12mg, but it was interesting and quite unique. Despite the side affects i found it useful, and it has potential in terms of getting something useful/learning from the experience.
The over-stimulation, muscle tension, gastric disturbance, and other side affects just kind of turned me off from it. If you do try it, start low, by low i mean under 10mg.
I plan on trying it again in the future, but for the moment its shelved in favor of novel 4-subb'd tryptamines. I do like how it feels less recreational/hollow, and more insightful than the other 2c-x's though. But i can get that from 2c-d or t-2 without so much side affects.
IMHO, its worth a try, some people love it, but its seems more volatile in how people react to it than the rest of the 2c gang. I agree with shulgin that its difficult, but worthwhile. People tend to underestimate how difficult going into their first experience though, at least i did 12mg caught me off guard. There's potential there though.
And finally, I've heard a few reports from nexians, and some other reports scattered on various sites that 5ht-3 antagonists help make it more bearable. So think lemon oil, ondanserton, ginger, etc.
Just be safe, i would say 20mg is a reckless first time dose assuming you plan on taking the whole capsule. Its far more potent than any of the other 2c-x's ime.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
