Assault - This has truly pushed me beyone my limits when it comes to the workouts. Pump's are crazy and I swear they last for hours. I mean, the guys that have tried it would have to agree that this is some great sh*t. Not only for the ingredients (cause that is key), but the taste! I'm almost to the end of my Assault, but you can bet your ass, that I'll be placing an order very soon!
