This pill is scaring me. They are promoting it BIG time in my area. The UFC promotes it like crazy and now MTV is airing commercials for it. They are really targeted teens and young adults that want a quick fix.
My own opinion is to always steer clear of these things. After all, they cost a lot and what happens when you stop taking them??
If someone is experiencing a lot of tiredness, there is usually something wrong. Maybe over training, under eating, lack of sleep. All problems that should be fixed themselves, not by taking a pill.
