The first time I tried this product someone gave me a sample pack, I held on to it for over a week until I remembered I had it and tried it and to my surprise, I went 2 hours extra/over my normal time of working out! The feeling was super good too. I finally bought a full size container and I'm enjoying it!
This stuff keeps you pumpin' and ready for hours, that's why it is a very valuable product for weight lifters, especially if/when you work during the day; I'd advise you to take it moments before clockin' out!

Good stuff
No such thing as too much good stuff. My workouts were starting to drag as my trainer added more strength and cardio intervals to my routine. What was taking 90 minutes off Nitraflex takes me 60 minutes on Nitraflex.

Love it !
This product is awesome. I have tried similar products from other companies and some some success and some not so much but GAT seems to price their items fairly and every product from GAT that I've tried has been outstanding ! !

Good stuff
I was building a tolerance with C4 so I decided to cycle onto this. The first time taking this I took a full scoop, I could feel the intensity of the 300mg of caffeine almost right away, I had a killer workout. The next time I only took 3/4 of a scoop, which turned out to be just perfect for me (6'00" @ 185lbs).

Overall, this is a good Pre-workout drink, gives you great energy and pump. It has a good taste. No itchy affects. You can feel the testosterone boosts after only a couple of day of use.

There was only 2 major side effects that I found that kept me from giving this 5 stars. First, I found myself struggling to fall asleep at night when I would take this at around noon that day, due to the large amounts of caffeine per serving (325mg). Second, it gives me acne. It will probably effect everyone different, but those were mine.
