Jun 8, 2009 7:11 pm: Out of NOExplode, Superpump 250, Black Powder, and NANOVapor this is really the best preworkout that i have used. The Jar might seem small, but it contains 45 servings which is about the same as any other jar. It tastes pretty good. There it mixes pretty well, although there is a little precipitate at the bottom. So far i have used 1.5-2 scoops and worked out like a crazy. If i did not put a time limit on my workout, i would be lifting for like 8 hours. It is pretty cheap, and definately worth getting.
