Positive impact

The main active ingredient in Assault is the caffeine content (200 mg per serving). Caffeine may be the most widely used stimulant in the world, for improving physical strength and endurance, also and systemic vasoconstrictor. Among other effects it accelerates fat burning.

The other stimulants ingredients are the B-vitamins and nitric oxide. B-vitamins assist with energy metabolism, DNA synthesis, the formation and repair of red blood cells. Nitric oxide is a molecule that our body produces to help all its cells communicate with each other by transmitting signals throughout the entire body, concretely in this case regulating blood pressure by dilating arteries. Nitric oxide increases blood flow and oxygen supply to skeletal muscles.

For other two important components, the creatine monohydrate and beta alanine in the supplement, researchers state that both require “loading periods” of ingestion over several weeks in order to provide the best effects. Creatine is a molecule in an energy system (creatine phosphate) that can rapidly produce energy (ATP) to support cellular function. It is an energy source for skeletal muscles. This is what causes strength increases after creatine supplementation.

Beta alanine is an amino acid that acts indirectly by creating carnosine. It is stored in the muscles and is used in high intensive training and muscle growth. High concentrations of carnosine helps to neutralize the effect of lactic acid and contributes to a higher quality and longer training.

Downsides of MusclePharm Assault Pre-Workout

  • Effective doses of creatine, beta alanine, and betaine anhydrous should be almost twice as big;
  • There’s no way you can double your serving to get an effective dose of ingredients mentioned above because that would give you an enormous amount of caffeine (400 mg);

Side effects

Bearing in mind that there are a large number of components in this mix, it should conduct a long-term and extensive research about side effects, which certainly exist if somebody goes too far with daily dose and continuous consumption. However, if you’re using the product exactly according to the manufacturer’s instructions on the package, you should not feel any unwanted side effects on a larger scale. This applies only to a perfectly healthy person.

Mild side effects like tingling/numbness in the face, lips, or extremities, jitters, cramps, headaches, flushed and red skin,
trouble sleeping, increased heart rate and blood pressure, dizziness, itching and anxiety are very likely to occur when using any supplement of this type.

Also, all pre-workout supplements on the market (regardless of the name and manufacturer) are highly addictive. Once you start taking pre-workouts, you will have difficulties training without them. Take this into account.

Suggested use (method of application)

The directions for MusclePharm’s Assault are fairly straightforward.

Mix one serving (1 scoop) of Assault in 8-12 fl. oz. of cold water and drink 20-30 minutes before training.

There is a warning saying not to exceed one serving per day.

Also, because of the caffeine content in this supplement, it is probably best not to consume it within about six hours of when you plan on going to sleep.
