Thanks to Adizzle1 for the sample packs. Took 1 pack ( 2 servings) at 6pm on my drive to the gym. By the time i got there (25 mins later), i was ready to hit the weights. Focus and pump were great, intensity was increased as well. This came on slow and steady and provided a nice rush throughout the entire workout. No inital cracked out feeling like jacked gave me. For the price, its def worth a try.
