Game Changing Kill Cliff has made a huge change in the level of training I am able to accomplish with my Jiu Jitsu and SOFLETE workouts. When protein, BCAA’s, and mobility workouts aren’t enough for recovery which is more often than not I supplement my diet with Kill Cliffs. I’ve had every flavor of recovery and love them all! Not to mention that it also helps my wife with her arthritis!

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.

Awesome Company! I accidentally purchased as a guest instead of my account, so I was unable to check on the status. I contacted support and received a prompt and friendly response. As well due to a high demand at the time of my purchase they changed the sale date of the product (which didn’t bother me anyways) so that it will have a longer shelf life once shipped.

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.

Re-Occuring Order and Grease on the cans. I love the product and have a small re-occuring order. I tried to alter and add product and was told I had to add a second order because the new on-line system would not allow me to change my re-occuring order? Seems odd. Secondly my add order this month came and all the cans had grease on the exterior. Each can had to be cleaned before the product could be drank.
