Preworkout question

[usd610]

So i want to start supplementing preworkout. Used to take Jack3d a couple years back but havent been taking anything in the past couple years. What should I be looking for as far as ingredients? Im going to be buying all bulk powders to save some money, and right now all i can think to get is beta alanine and arginine.

Also I have heard that arganine needs to be combined with glutamine in order to produce an NO2 booster, is that true?

ive heard that arginine needs glutamie to convert to NO and citrulline, but its not quite true. glutamine simply helps arginine sythesis. what u need for argining synthesis is NADPH, water and oxygen.
