ATHLETIC PERFORMANCE with and edge! Designed for the modern-day athlete, Assault is GREAT-TASTING, ENERGY-ENHANCING pre-workout supplement that helps you push past your PERFORMANCE limits! Featuring proven, researched ingredients for STRENGTH and POWER output as well as improved ENDURANCE and recovery time. Take your game to the next level with Assault! CARNOSYN BETA-ALANINE – is a leading ingredient in sports nutrition formulations included to support an increase in muscle carnosine (a molecule that helps buffer acid in muscle) and athletic performance. Beta-alanine has been shown to enhance muscular endurance, as well as improve moderate to high-intensity cardiovascular exercise performance CREATINE MONOHYDRATE – one of the most popular and studied ingredients used by athletes looking to build lean muscle mass, maximize performance and increase strength BETAINE ANHYDROUS – occurs naturally in the body, and can also be found in foods such as spinach and beets. Some research suggests that betaine might improve certain aspects of exercise performance TAURINE – found in large amounts in the brain, retina, and heart. Taurine is an antioxidant and may assist with reducing inflammation, as well as promoting normal heart function. L-GLYCINE – the smallest amino acid in size, but has many powerful effects on the body and is involved in a variety of biochemical reactions CAFFEINE – has been shown to increase energy and endurance, decrease fatigue, and improve focus. Many athletes have benefited from the effects of caffeine and use regularly both in their training and competition ACETYL-L-CARNITINE – an amino acid the body uses to turn fat into energy. It is not normally considered an essential nutrient because the body can manufacture all it needs. However, supplemental carnitine may improve the ability of certain tissues to produce energy VITAMIN B6 & B12 – each fill many different roles that support your body’s metabolism and help it produce essential substances, such as neurotransmitters and red blood cells SUGGESTED USE: Mix one serving (1 scoop) of Assault in 8 – 12 Fl. Oz. of cold water and drink 20-30 minutes before training. Do not exceed one serving per day.

Great product +for those who like a cleaner Pre-workout at a reasonable price.

As a 25 who frequents the gym and has tried the second generation of MP Assualt and this one. I am a bit indifferent about this.

One of the best pre workouts I have ever taken!

I’ve tried a lot of pre workouts over the years and in my complete and honest opinion, assault black has been one of the best. There’s no proprietary blends so you know exactly what you’re getting. The pump matrix is spot on and there’s just enough beta alanine for some of those nice tingles. I highly recommend this to anyone who needs a nice pre workout.

Great Pump! Great Taste! No Bad Crash or Feeling.

Just finished up using the last of my MusclePharm Assault Black Pre-workout today and I must say.. this has been a good preworkout for me. It is a great pump especially for those morning and evening workouts! I have noticed a consistent energy level throughout the whole time in the gym. I also don’t remember any bad comedowns or crashes. Pretty much this gives you the energy to workout to a very satisfying feeling then providing you the drive to finish your day strong. Very good product. A+ Rating!

It’s good as a pre workout supplement

It’s good as a pre workout supplement, but not perfect. It definitely gives me a boost, but sometimes it gives me a bloaty feeling, which is not what you want during HIIT. Also, don’t use this if your workout will be less than an hour, or for light workouts, or else you will keep feeling it after you are done. I notice if I don’t work out hard enough I get a tingly, prickly feeling everywhere. So only take it for intense or 1 hour + workouts.

good energy decent pump

Works well,

Good stuff… start with a lower serving size and work up.

34 yrs old; been working out for 14 years. Took all kinds of pre workouts throughout the years from the original Vapor Nano to todays stuff. This is legit. If you can handle your pre-workouts this stuff is for you. For the hardcore guys you are probably going to stack this with stuff anyways; but this was would be a good one because of the ingredients. This one doesn’t mess around. I went to order more assault pre-workout or whatever it is called and this came up under similar products. Glad I tried it. A little goes a long way. Sometimes I don’t even take a full scoop and I get a good wakeup workout. Great pump too!

I’ve been very happy with Muschle Pharm products but this is the first time I used this pre-workout. The taste is great and the consistency isn’t too powdery. It dissolves easily unlike some other preworkout I’ve used. For me it really gives me an even energy level over my entire workout. Some other preworkouts hit he fast at the beginning but then I end up sluggish at the end of the workout, but I’m sure this all depends on the person. For the price I would definitely suggest trying this.

I fell like I get tons of energy after taking this pre work out. I go longer in the gym without feeling jittery. It does give you that prickly/ itchy feeling but that is when I know its kicking in.

Good, but not great. Great source of energy and extra motivation for the workouts after a long day. Decent amount of stim. If you don’t like the feeling of beta alanine, I wouldn’t recommend this product. 4 stars because of the reasonable price. GNC or other retailers will charge you double for similar quality.
