Vasospan is a nitrix oxide product from Neogenix. Many of their products are very expensive, so when I got the chance to log one of them I was excited. I took it during my cutting cycle in hopes of reducing body fat would increase vascularity and pumps. This product contains an advanced form of arginine, l-ornithine, and l-norvaline to create a powerful trio. You take 4 tablets two times during the day spaced out about 6 oz. I liked taking my first serving twenty to thirty minutes before a workout. During the workout, I would notice my veins popping like never before. My power went up on incline bench and I was able to do 4 more reps with dumbbells even though I was losing weight. The veins came back at night and I looked so ripped. I can't compare this to PlasmaJet because I took Plasmajet with some other stuff and the emphasis was on getting stronger. A whole bottle provides 30 days, but you probably could get away with just taking it on workout days to get a little boost. Solid product!
