I know one guy that's on NOxplode and he swears by it. He's a big guy, but he didn't get big on that stuff, he started taking it after he got big. He's been on it for about 8 months and his bodyweight hasn't moved more than 5lbs and his lifts are pretty much stagnant, he added about 10 lbs to bench. So I'd say that from the scientific aspect and from this guys experience that NO2 isn't really worth it.
Load up a barbell with alot of weight, put it on your shoulders and stand there for a bit....and that my friends is a cheap man's NOxplode
