I have found mixed results. Look for damiana or horny goat weed in the ingredients. The ones that show the most promise in my opinion are Crunk, Cheetah, and 69. They have very different tastes though. These do seem to work a little but are not entirely effective.

Most of them rely on caffeine, sugar, and B vitamins to perk you up. The problem is that they wear off, after a while and you crash.
A better solution would be a good diet, exercise, and the proper amount of sleep. There are no quick fixes.
Oh, and yes, there are side effects from using them. Taking one particular vitamin in excess will cause your body to not absorb the other essential ones, resulting in a vitamin deficiency.
