thing is... with nitrix, its not really a Pre-No workout product, its more of an all day thing... and with me, my headaches lasted 3 weeks, after only 3 days of use. It sucked, during lifting, running, sex, anything really....
If i could figure out how to take nitrix and not have headaches i SOOO would...
its by far in my book the best damn supp, just because of the effects on your body all day long, hard, cut, vascular.... its a great product, beside the fact!
