MusclePharm's Assault is one of the more popular pre-workout supplements on the market. I have used it for about a month, and overall I really like it. It contains many ingredients that help build muscle, increase performance, and gives a nice steady flow of energy through the entire workout. I definitely notice increased focus as well. I have yet to try all of the flavors, but the raspberry lemonade has great taste. I would recommend for those people looking to make each workout a lot more intense. From your first dose onward, feel a performance-boosting power surge that will power your entire workout, from stretching through to your final set.
