It`s rather nice actually and I wouldnt say its a stim at all because it doesnt make me talkative or keep me awake. Like a head stone or mellow coke feeling and great for a midweek binge where you dont want to be too out of it. A bit like dmc with no negs (doesnt keep you awake).
Nothing remarkable but as I said great for a buzz when you need to get to bed early with no hassles.
I went through 200mg in 4 hours so it IS fiendish as I usually dont go through any more than 100mg of anything midweek. I mean anything in the 50-250mg range.
Lasts about the same as coke hitwise.
