Although this stuff is expensive it is by far the best arginine supplement I have ever taken. I started to take 2 grams before and after workouts but then decided to start taking just 3 grams 1 hour to 30minutes before and none after. It worked from the very first dose. My viens have never been as pronounced as when I took this stuff and I have tryed no-explode,nitrix,no2,and several other no2 products. If you want a better no2 product give this stuff a try. |
