To be honest I was skeptical To be honest I was skeptical, I've tried enough products to know they generally do not do what they say. If they they do help performance, there is something that makes them unpleasant, like caffine, flushed skin, tingling etc. But, after a nine mile run for distance and the next day an 5 mile run with hills, the product did exactly what it claimed - no quit. I ran with pleasure - not missing the normal low gut feeling of not wanting to keep running. I will be using these products this year for two Spartan Trifectas.

Tried tree different ignite energy… Tried tree different ignite energy drinks, all taste disgusting beyond belief I'm shocked it did not make me puke.

I have been using the product for about … I have been using the product for about three years now and love the product. Customer service is great as well. I had to update my info. and the website was going through some maintenance so I called Kill Cliff directly. Spoke with a gentleman in customer service, extremely nice and helpful. He took care of my issue right then and now I am expecting my order to ship out right away!

Tastes great - highly recommend! Tastes great - I love the Berry Punch & it does give me the extra endurance for my workouts, I’ve tried a variety of brands, found this brand through Tough Mudder. No jitteriness. Also being a Navy mom - I’m a huge fan of the concept it was created by a Navy Seal.

Is this coming from another planet? What takes so long???? I'm not rating the product, I'm rating the delivery process. I placed an order online on 4/24 and it is 5/3 and I have yet to receive the order. There is no tracking information either. This seems the be the norm when ordering from Kill Cliff. It takes almost a month for the product to arrive. That is beyond inefficient and entirely unacceptable.
