Something to think about.

what I do with this product isn't for everyone. I suffer with a lot of pain and fatigue. I take a pure kick or a c 4. Drink mix. Mix then in a tall glass of ice water and my pain and fatigue are lowered enough, I can get up and do what I need to do. The cost is high, butits worth it for me.
