Energy drinks or their equivalent have been around since the beginning of wrestling. Anyone remember the honey shot or other things that you would do to increase energy? If used in moderation and along with proper nutrition I don't think they hurt any more than a candy bar and soda, except they have more vitamin and nutritional benefit. I know I swear by Advocares’ Spark, enough so that I purchased a dealership just to purchase for me and my family to get a discount. I have sold to a few individuals when they ask, but usually at my cost, not at profit. I also agree with the mental focus being important and helping. Does this one product or method work with everyone? Of course not. Nevertheless, for us, Spark gives a spark. It is kind of amazing though that people talk about caffeine and let their kids drink soda all day at a tournament. The truth is that caffeine on it’s own is a depressant and there is a comedown after usage. The use of the product has to coincide with appropriate timing or the effects can be detrimental.
