Yes, I have tried it before (and now).
I don't think smell is a reliable indicator of purity. have you tried it yet?
I know, but it just smells worse than the last time I had it, so I was assuming that's because there is some acetone and esters in it. It was much easier to drink what I had before because of the taste. So if you can get 99% definitely get it, otherwise you probably shouldn't bother.
It's very nice. You just have to make sure you don't have anything important to do the next day. I think I should reinforce something I said earlier. The drunk feeling lasts only a few hours, then you get this benzo feeling after that and into next day and it's strong. Felt like I took 3 xanaxs today. Can't really type or think too quickly. I took about 10ml last night and about 8ml the night before. To start off, I'd recommend 3-5ml and go from there. Do not drink it straight. I tried 1ml like that and felt like I had strep throat for a few hours. I also noticed it to be very "redose compulsive" I forgot what you call it. I was only planning on taking 3ml the second night, but I ended up slowly upping it to 10ml over a couple hours.
That reminds me, if I remember correctly, I poured some on a towel and inhaled it like ether (never had ether). wow. It felt like MXE or ketamine for maybe 10 minutes. I was stumbling around running into objects and not even giving a fuck. Probably not something I should look back on haha.
So yeah, like I said, get the 99%. If you can't, then definitely don't use it too often because whatever is in the impurities is nasty. The taste of this impure stuff is almost intolerable, even when diluted. If you're ever able to find cheap 3-methyl-3-pentanol, that's what you should get instead. According to my research it should be more potent and smell fruity. It's just hard to find and pretty expensive. It's essentially the same thing, just has the methyl replaced with an ethyl group on the one side.
Forgot to mention - Do not get 1-ethynylcyclohexanol or methylpentynol or anything else with a triple bond. The unsaturated molecules with the triple bonds are pretty bad for your liver. Completely depletes CYP450 which is an essential enzyme. You can get them, but don't take them very often or with anything else. That's why even though those are more potent, I, and most other experimenters, stick with 2-methyl-2-butanol.
