So here's my report. It's a bit late, but it's better than nothing. 5-IT gave me the almost uncontrollable urge to constantly text all of my friends, so I've kept a pretty detailed log of the day
I was at an outdoor dance festival. It was mainly house and related genres. Usually not my cup of tea, but the 5-IT helped me with that. It was a beautiful day, the sun was out all day long and there was a very nice and friendly atmosphere around.
T+0:00: I Dropped my first 125mg 5-IT bomb at 2:00pm.
T+0:45: Starting to feel a bit floaty/feathery. As if I'm really light. The constant sun is a bit overwhelming at this point.
T+0:50: The euphoria shows it's face. I felt very happy, nice and warm. This feeling of well-being gradually got better and better over the next few hours and stayed with me for many hours more. Also, every now and then I had these nice tickelish rushes going through my body, as if a thousand tiny fingers tickled my body from top to bottom. Music sounds great. Dancing with my t-shirt off on a tiny beach.
T+1:20: Still coming up. Really starting to like this substance now. To me it feels a lot like mdma, but without the mindfog that mdma gives you. Crystal clear thoughts and (to me this is one of the most important plusses of this substance) normal or even slowed down perception of time. When I'm on Molly, the day/night just passes me by like a speeding train. On 5-IT, 15minutes could sometimes feel like 30minutes. Also becoming a lot more sociable.
T+2:30: Still coming up. The ever increasing euphoria and feelings of wellbeing are awesome. It just keeps getting better and better and better. Didn't really roll hard at this point, but felt incredibly nice.
T+3:30: Dropped another 60mg bomb somewhere around this time. I don't really know why, I think because I wanted to be on my plateau until the end of the day.
T+4:00: Some MDMA-like mind fog starts to form. Coordination start to become impaired as well, which had not been a problem all day. I start bumping into people and such.
T+4:45: The second bomb keeps coming up as well. Feelings of well-being still increasing.
T+5:00: Starting to get ridiculously horny

But no opportunity to do anything about it.
T+5:30: Keep texting my friends about how great this stuff is.
T+6:00: The muscles in my legs feel tired, but even this feeling is somehow nice.
T+8:30: Dropped another bomb 30 minutes ago. The MDMA-fog is starting to get even more apparent. The euphoria is subsiding a little as well. Some mild OEV's start presenting themselves. Probably because it's getting dark.
T+10:00: Festival is done, taking a bus home. Me and my girlfriend (who also had taken 5-IT) could not sleep the entire night. My GF told her entire lifestory in one go, probably took her about 2 hours or so.
I felt really crappy the day after, but that was probably due to exhaustion and lingering after-effects. At about 5:00pm I felt fine again. Next time I probably won't redose as much as I did, this seemed to only make my mind fogier. I love how 5-IT gets you this high of which I thought is incredibly similar to MDMA, but with a clear headspace. And long come-up is a big plus as well. Every 15 minutes you realize that you feel better than the 15 before. And it just keeps on building. Also, something that I should mention: wear sunglasses. Me and GF had our wordt terror-faces ever on this substance. Huge dilated pupils and eyes wide open. According to a lot of people we looked really creapy, sometimes even frightening, without our sunglasses. You can also expect a lot of bruxism. Had pretty sore jaws the two days after.
