I did a Google search and read that "Lost 10" was the strongest retail brand. Blue can, tastes like bubble gum.[xx(] I like Rockstar in the blue can the best. It’s strong and has a berry flavor. I don’t know why someone doesn’t just market a bottle of effervecent pills you just add to "any" drink to make it an energy drink! I can see the Oxy Clean guy now- "We all love energy drinks", "We don’t all love the taste", "And we certainly don’t love the price!"-Introducing new (insert product name here). Being a pill i think the FDA would be involved etc, so in the trash with my Subway scented air fresheners.[:D]
