I liked the OG version and figured Id give this a shot. Tried .5 tab last Friday then another half tab 3-4 hours later. Kicked pretty hard once the 2nd tab kicked in but not clean at all for me. Figured Id give it another shot today at 1 tab on empty stomach, OMG! My hands are shaking like crazy and heart is beating extremely hard and fast. I really don't like this. If you're looking for stimmed out of your mind and don't mind shaking like a leaf on a tree, go for it. This stuff is very potent but what you get feels like a very dirty stim affect. Im not very sensitive to stims either, nothing has hit me this hard before, and I don't mean that in a good way. After this, if I use again, it will only be a half a pill but I think Im done with this stuff. Too strong and not clean, so if you try it, be careful! Maybe its just me, but I typically have a regular effect to other stims I've used.
