I don't know about the Mystic but Foxy is pretty cool. It is a funny combination of acid, rolling, being way high and generally fucked. I did a fairly high dose this past weekend and has a mental trip with soft loops and waves of thinking. The visuals are minimal but very effective. Everything stayed the same but looked not quite right. Everything is just a little funny looking. Dimensions and shadows are enhanced. While on foxy, you look pretty normal and coherent. The body buzz is very intense though. Two other people that tried it this weekend couldn't take it. One said he'd rather have an awful acid trip. I had about as much fun as I do when I roll. You can sense vibrations all around you… kind of like when your foot has fallen asleep and is waking up, or like you are moving over cylinders of static. It can vary. It's very hard to describe it all but is rather something you just have to try. Of the six people that tripped this weekend, two of them said they would never do it again and four of us loved it.
