Can Kids eat...?
Kids have plenty of energy. We specialize in products that have caffeine and caffeine is not recommended for children. Always consult your physician.
How much caffeine is in...?
If if the manufacturer tells us, we try to list how much caffeine is in each product. If for some reason we don't have the caffeine content, you might want to try EnergyFiend.com. A more interesting way to measure caffeine content and effect can be found at Energy Fiend’s Death by Caffeine page or at Vroom Foods’ comparison chart.
How much sugar is in...?
We do not track how much sugar is in each product but we do try to list the ingredients in each product.
Why should I buy from you?

We plan to run lots of specials as well give-aways. So, yes, if we’re not giving away free samples today, we will soon!

Why don't you have more energy drinks?
We love and support all the other energy products out there. But if you can get it at any local grocery store or convenience store, we probably don’t carry it. But, hey, we love pretty much all the energy products out there. If we don’t carry it but your local store does, buy it there!
