MUSCLEPHARM ASSAULT is a pre-workout amplifier that will help you take your workout and training to the a level you never thought you could achieve! Use ASSAULT pre-workout, or sip on it during the beginning of your routine. From the moment you take your first sip of Assault, you will feel its performance-boosting surge.

Assault is Musclepharm’s premier pre-workout supplement and is one of the most researched pre-workout on the market. Being athletes themselves, the developers of Assault wanted a product that would do more than provide serious muscle-building power. They wanted to have the safety bar set sky-high so other athletes know that helping their bodies with this supplement is not hurting them.

We are happy to announce that Assault is one of the only Pre-workout supplements available that achieved certifications from both NSF and Informed Choice as Banned Substance Free.

Con-Cret®: We were the first to offer this version of creatine in a pre-workout product.

Astragin®: A patented, clinically-studied ginseng extract, Astragin® helps the absorption of many different nutrients.

Cinnulin: Like Astragin®, Cinnulin helps support ABSORPTION, so the creatine, arginine, vitamins and other ingredients in Assault can power up your muscles.

BCAAs: Unlike “concentrated” formulas that hit hard, then leave you for dead… Assault is there from beginning to end. The BCAA in the formula is a patent-pending 3:1:2 ratio which is higher in leucine and valine than isoleucine. The addition of these amino acids assists in recovery and helps build lean muscle mass.

The Complete Package: 4g beta alanine, 5g of Con-Cret® & Creapure creatine, 1.5g citrulline malate, 6g BCAA, carbohydrates, vitamins, and our special High Performance Energy & Intensity Amplifier blend* – All of this IN EVERY SCOOP.

I like the green apple flavor but the main thing is that this stuff really does work. I can feel a difference in my workouts.

Nothing Like It!

Submitted by: Jason Sperry

I have noticed a big increase in my workout performance when taking Assault. I use to only take Protein after my workouts and now I see what all of the buzz is about for preworkout supplements.

I really like the taste of the blue raspberry. I really liked the initial boost that Assault provides. There are a few ingredients that I would like to see added to the formula but overall this is one of my favorite products to take before I work out.

This stuff increased my workouts by almost double. The increase in focus is great along with how much longer I can workout has been awesome.

This is great for before I lift but I still haven’t used it for my cardio workouts just trying to see how my body handles it. So far I would say this stuff is worth the money. I’ll post more when I am finished using the whole bottle.

I wanted to use this stuff before my football games to help increase energy during the games and help my muscles last to the end of the game.

Basically what I noticed when taking Assault before the games was an increase in energy and improved endurance but it also seems to make me a little to scattered. I felt like my focus was effected a little.

This stuff ROCKS! My energy increases a ton on this stuff and for me I would say that my focus was increased as well. My muscles seemed to last twice as long as they use to be able to when I didn’t use Assault. My mile time improved to a 6 minutes and 7 seconds down from 7 minutes and 25 seconds. Great Stuff!

Stomach Pain!

Submitted by: DBrinck

This stuff caused me to have bad stomach cramps during my workouts. I tried it three times and then quit after the third time I had bad stomach cramps.

Great PreWorkout!

Submitted by: Jake Hillman

Great Pre Workout, Good tasting flavor. I wish it didn’t take such a large scoop. Make sure to have a little something in your stomach, before you take this.
