Here's my 2 cents:
I took 30mg measured on a 0.001g scale lined it up and snorted. After 10 minutes or so I started to notice the firstr effects, namely mild aggitation, no noticable peripheral effects which was odd as I felt like my body was flooding with epinepherine (sp? [adrenaline]) but heart rate, body temperature etc stayed steady. I felt slightly jumpy and generally uncomfortable.
My vision was affected slightly, walls warped slightly and dimensions seemed deeper i.e close things seemed very close while things that were further away seemed a long way from me.
After 45 minutes to an hour nothing had really changed, the effects were waring off slowly and gently.
I lined up another dose of approx 60mg. After 10-15 minutes I felt happy, not euphoric but in a good mood. The aggitation turned slightly into anxiety but it never got too heavy.
The effects lasted approx 1 hour until the peak slowly reduced.
The morning after, I felt slight nausea although less than would occur with alcohol.
With this experience, I was not impressed, from what I've read, the dosages required vary so much from person to person and the environment the user is in at the time.
I will give this subastance another chance at a house party to see if envronment improves the effects.
My experience, while at times uncomfortable, never reached a point where I wanted to abort.
I hope the above info is interesting to anyone planning on researching this substance. I do NOT recommend that anyone takes the high dosages that I took. Start low and work your way up slowly. I am what Alexander Shulgin would call a "Hard Head" and generally need higher doses than other people to get the same effects (this is not said in a bragging way, I wish I was not a "Hard Head", it would save me a lot of money!)
Euphoria - 5/10
Anxiety - 3/10
Overall - 4/10
I will update after the party situation to see if the effects improve at all.
EDIT:
The substance received was a very fine powder of a similar consistancy to white flour. It was white with a very slight yellow tint making the powder slightly beige. There is very little odour and at the dosages taken, there is an unpleasant bitter taste but it is not overbearingly strong.
