These have been a real asset to my workout regimen in the afternoon when I have worked all day and become tired. Not sure about the claim that they work all day, for me it wears off within an hour or two which is exactly what I wanted to do, but they do kick in very fast and my pills are almost a year old and they still work perfectly. Anyone buying pre-workout is literally throwing money away, these things are seven cents a pill where as pre-workout is about a dollar a serving and the only active ingredient in the pre-workout is caffeine. Not sure how it may affect other people because I take in zero caffeine other than these pills to make them more effective for my work out. I actually only take a half a pill which is 100 mg about four times a week.

This is a great caffeine product. After taking one pill in the afternoon I'm as good as new and able to function at work just like I just woke up. It has improved the quality of my life significantly for that I'm very appreciative.

I take one of these pills before I work out daily and these are my energy boost at the gym. No shakes or any other problems. I would definitely recommend these!
