NOX3 is a good product at a great price. If your looking to get pumped up, it will surely work for you!

Ive been on nox3 for over a week now and havent felt any of the normal pump one would expect from even your average no2 product. it suggests taking 6 pills a day and ive tryed as many as nine on work out days but have remained very unimpressed.  
 

This stuff isnt that bad taste pretty good not horrible. Def. feel a rush in the gym... workouts are longer....not sure if the pumps are as huge as NO2 ... your heart may rush while taking this.. i know mine does...its like you cant catch up to your breathe. think that a good hour wait before going to the gym is needed...

I have tried several NO2 type supplements and it usually took until the second bottle to really start feeling the pumps of these products. I have always trusted Universal for my Aminos so I wanted to try this. I was not disapointed. Right off the bat on back day I had one of the best pumps in my lats and it is hard for me to achieve this in my back. The next day was arms and I felt like my biceps were going to explode. What an awesom feeling I had. I felt like I stayed pumped for hours too. Not only do I think this NO product is better than the leading brands but it is cheaper too. You have got to try this and see for yourself. The biggest catch is timing in your diet. Make sure you are timing your protein and carbs at the right time for taking any L-arginine product. Other wise I believe it will not work with anything.Get that right and you will be having great pumps. If you need any help on when to take this come read this thread.  
 
Good luck.
