Atomic Tabs is not a pre-workout. It is simply an
energy chew, similar to
energy shots (like
5 hour energy), only better.
There's no creatine, arganine, etc. type stuff in
Atomic Tabs, just some B Vitamins,
Caffeine, Taurine, Beta Alanine and Glucuronolactone.
You can use it as a pre-workout however. I do.
Remember also that Power Chews' serving size is 4 tablets.
Atomic Tabs is 1 tablet.
