Stacker 2 Original Review Energy Pills
You can see Stacker products all over the place. 
I have tried their caffinated mints, their amazing-tasting Stinger drinks & shots (small drinks), and now their pills (which I bought at Wal-Mart).
They work pretty well. I went through all 60 capsules and each time, the rush was quite good. I usually mix them with guarana pills or ephedrine pills, if I can find them. Sometimes I mix them with an energy drink too, just to get that extra “oomph”.
Stacker2 is a likable brand too. They do a good job getting their product to market.
These pills contain kola nut, yerba mate, caffeine, green tea, white willow bark, etc. It’s got a few other items that help with weight loss, so it’s marketed to be a weight loss formula.
