Where possible, most people should stick to the tan coloured stuff, tested with the Marquis. For those with the white crystals, let us know how it goes but don't expect much.
I had the white tiny crystal MDAI last night.
I read a lot about MDAI on this topic, so I know I didn't have to expect too much from this chemical being only a serotonine releaser.
It came from a very trusted vendor, one the "big 5" that gave me a 6-APB sample for free which I loved

But then after reading here that white crystal stuff ain't good (someone even tells it might be dimethocaine), I decided to take a very low dose of this compound (I never had MDAI before so I dont have anything to compare).
I took 120mg inside a capsule, then went out with 2 friends for a couple of beers.
At +40 my hands started shaking way too much.I coulddn't control that, I coudn't keep the glass in my hands w/out shaking or hold my cell phone with one hand. (I never get this on MDPV or MDMA, M1, MEPHEDRONE etc.).
My friends noticed it and I had to tell them I was on drugs cause they noticed I was anxious too, my heart was racing too much and I couldn't smile because I felt too much tension on my face.
Actually It was kind of scary, and I was worried. Anxiety might have been increased by the fact that I did not want them to notice.
I felt I have to drink to relax, so I had 2 vodka lemon in 20 minutes (I have a big tolerance for alcool though).
At +1h20 anxiety and shaking was all gone, my heart still beating fast but not annoying me. Mood elevation, nice to talk with friends and even nicer to go for a walk. Smiling a lot. Subtle sensation but I actually liked it. Face felt very warm.
At +2h I wished to redose but I didn't have MDAI with me so it just worn out... no come down, but actually I wasn't high really, just feeling good.
At +5h sleeped with no problems (50mg of Lormetazepam was taken, that's my prescription for sleep). But once fallen asleep I woke up many times, and I dreamt a lot, weird for me cause since I 've been on benzos (2 years) it's hard for me to dream.
Considerations:
I really don't know. Does this experience fit with someone having the tan stuff? I don't understand the shaking and the anxiety. It felt a little like a stimulant come down, while I was actually coming up from a serotonine releaser.

I might have underdosed. Sometimes I felt anxiety when I underdosed cathinones. I don't know. Any suggestions?
I was planning to IV MDAI (I have a needle fetish since I was an heroin+coke addict 4 years ago) but I want it to be pure stuff, I don't IV street drugs no more.
