This chiznit is INSANE. I am in no way stim sensitive. I was doing 4 scoops a day of alpha mine no problem. I literally cannot handle one tab of this stuff. Cannot believe the harshness of the onset, and I love the way it tapers off with zero crash... I've gone down to a half tab a day, sometimes I'll take the other half part way thru the day but that almost hits as hard as just popping the full pill in the morning. Great freaking job formulating this stuff. I was playing with it last week, but I'm starting my cut for a December vacation to Jamaica, and I'll update for the actual effects of fat loss.
