The Rush is what I am familiar with. I haven't actually opened my formula for the designed results in the Prevail. I am familiar with the Rush. I dropped the Cognition and bonus Triumph, and will test the response of the standard prevail. I am curious to know the difference between the two products. Rush and Prevail. One is geared for a change in mindfulness. One is geared for overall workout results. I will keep you posted as to the overall gratification while working with the product. I look forward to serving you a response as soon as possible. Rush just jams! Flat out! Later guys. You're the best. Keep up the good work. Thank you for the encouragement on Fathers Day. A beautiful occasion.
