I recently decided to try out ATP Extreme for a few days as my pre-workout supplement.  I also gave it to my training partner to take along aside with me.  I took my first dose of 4 caps about 30 minutes before the gym.  I remember shortly after pulling into the gym parking lot I was actually starting to “feel” it kicking in.  The best I can describe it as a “flushed” feeling, I can only imagine from the increased blood flow, nitric oxide / production effect. This translated in the gym as well. My training partner and myself both trained doing high volume shoulders this day and our pumps were truly intense!  Very rarely do my shoulders get so pumped up that I have to rest my arms on something elevated in-between sets.  I am a fan!
