Product Works for me

I've put it through the wringer

It has become my endurance training fuel for events over 2 hours. I have tried other products and have settled on this. I had been a Hammer Perpetum user and for some reason my stomach started to react after five years. Made the switch and now days of 2-4 hours on the bike are full of energy. The test will be can it be consumed over a 5-12 hour day, multiple discipline day. Also works for BC skiing/long hard days.

My go to energy drink

I've put it through the wringer

I stumbled across this product at my local bike shop prior to doing a 40 mile ride (my 1st 40 miler). I am diabetic and always concerned that I'd be on a long ride and my glucose levels would tank leaving me in a very bad situation - if you are diabetic then you know what I mean (similar to bonking as the term is used in cycling) but probably a bit more serious. Because of the diabetes, I would not take my medicine before my rides (I typically ride very early mornings) because of my concern of low levels, but with this product, I no longer have those concerns. I wanted something light (don't like heavy meals when riding, don't like milky type drinks or overly sweet tasting drinks when riding either) that would keep me going once I got out on the road and this was just the ticket. I use it as a supplement to my one pack of oatmeal meal before a ride along with a honey stinger organic waffle and banana; it keeps the energy levels up and includes ingredients to keep your electrolytes in order, too - not too bad, huh. During those long rides is a time when I as a diabetic welcome loads of carbs and bit of caffeine don't hurt either. It mixes well and the taste is very very light, too; I like the tropical fruit flavor. At first I thought it was something wrong because the taste was so light, but later read that that's how it is. I carry 2 water bottles on all my rides and this energy drink will definitely be one of the two drinks that go with me on my rides. Before buying a jug, you can try one of the single packs to see if you like it and which flavor you like best; they actually taste pretty good. I would not recommend this to those that are couch potatoes though, especially diabetic couch potatoes.
