Tried it with a couple of friends in my flat, nice relaxed atmosphere. I'm a 5ft 10 male and weigh about 10 stone. Have experience with weed, MDMA, mephedrone, methylone, ketamine, MDAT, MDAi and salvia.
T + 0 - Bombed 0.05 after doing an allergy test and getting no reaction.
T + 45mins - Started to get threshold effects like something was about to happen or something would happen if I took more.
T + 1hr - The feeling subsided so I decided to up the dose and bombed 0.1.
T + 1hr 35mins - The previous feeling returned and gradually got a bit stronger over the next ten minutes. I felt a slight boost in happiness. No body buzz, just a very mild euphoric feeling in my head, like I had taken a very very very small dose of MDMA. Perhaps the feeling is similar to the first few minutes when MDMA starts to kick in, when you know that your about to feel very good.
T + 2hrs - Still had the same feeling, it had not increased. Still no body feel to it at all. No tingling or rushes. Just a very slight uplift in mood, similar but a little bit better then MDAT.
T + 2hrs 10mins - Wasn't sure if I still had the feeling or not, its so mild its very hard to tell. Snorted a 0.1 line. Smelled and tasted like sweet soap. Like some mixture of soap and candyfloss, which is interesting seeing as Donny said his smelled like mcat (note I have had plenty of experience with mcat and would definately definately know if it was mcat). The dripback was fine, literally very little taste.
T + 2hrs 15mins - The ever so slight uplift returned, but you have to really look for it. It made conversation a little more enjoyable, but not much more than being in a good mood would do. It literally is an artificial way of putting yourself in a good mood.
T + 3hrs 30mins - I got distracted by doing something else and completely forgot I was testing this new drug. Decided to try a much larger dose and see where that would take me and bombed 0.3.
T + 4hrs (approx) - The previous feeling came in waves, but wasn't really any stronger. Was just generally in a good mood and enjoyed conversation or doing other tasks like cooking hash fudge and watching family guy. You would be forgiven for forgetting that you were on a drug.
T + 4-5hrs - Was struggling to record time by this point, but not due to the drug. Was just being lazy. At some point in that hour we had a spliff, which felt a lot better than usual. It really brought out the 5-IAI and actually gave a slight rush. Those of us mcat lovers will remember how good smoking was on meph, similar sort of thiing on 5-IAI, but more noticable because your not so high in the first place. Didn't have a lot of the spliff but still felt pretty high, and it lasted for a good couple of hours. Certainly way longer then that amount would usually have.
T+ 6 hrs (approx) The weed wore off and I was completely at base line. The only side effects I felt was a slight awareness of my brain i.e. verging on a headache. Not painful, just aware that my brain was there.
Conclusion: Similar to MDAT and MDAi in that it just gives a very slight uplift. Didn't last very long, although it was kind of hard to tell how long it lasted because it was so mild. Worrying that Donny's smelled different to mine, even though mine was a very white powder which indeed looked very much like meph powder (I usually bought crystal). I don't know if this was truly 5-IAI but I can only give the experience of what I did take. Sorry, wish I could be more helpful. I woke up this morning with no hang over whatsoever. Slept for the usual 7-8 hrs and I feel fine.
