At the Arnold Classic I got a free sample of Stimulant X from the Anabolic Extreme booth. I normally drink a cup of coffee or a sugar free redbull about a half hour before my workout. I took one capsule as directed and I have to say I got a huge energy increase. This was even better than the ephedra products i have taken before. I gave one capsule to a training buddy who is a caffiene addict. I advised him to take it in the morning but he insisted it couldn't phase him at 8:00 pm needless to say there was a voice mail from 5:00 am on my cell saying "man you were right!" So for anyone looking for an occasional pick me up to get through a long day I'd recommend it. I haven't searched for it's price yet but I can't imagine it costing more than your cup of coffee a day and especially not more than a red bull.

Just my experience with this product and attempt to help
