I could be completely depressed and sleep deprived, drink a scoop of that, and the ONLY thing I'll want to do is get in a squat rack and put some heavy shit in the air.
The only reason I recommend that is it's the best pre-workout stimulant I've ever tried, and I've tried a few. YMMV but Jacked 3d with the DMAA ingredient is known in weightlifting circles as a miracle substance. Tear off the damn label if it bothers you.
@ceejayoz literature on creatine is pretty sound, unless your diet provides enough creatine, supplementation is beneficial. Here's a literature review: http://examine.com/supplements/Creatine/
The problem I have with that is then I'm dependent on a drug to get myself to workout. Anything like what you linked is most likely not good for you on a regular basis. My problem is my mindset, which will take time and effort.
My overall point is that while these "scientific" workouts are not the best way to workout, people should at least do something instead of nothing, similar to what DanielStraight said. Then if they truly want better results, they should follow routines like yours.
