MusclePharm Assault Ingredients

With a focus on strength and explosive energy, Muscle Pharm Assault ingredients have been carefully chosen to enhance endurance and deliver sustained energy. With no proprietary blend, Better Health Organization breaks down the 11 Assault Pre Workout active ingredients and explains how they can take your workout to the next level.


With 3 grams of creatine, and 250 mg of caffeine anhydrous, MusclePharm Assault is designed to deliver explosive energy.

Vitamin C: 300 mg – A water-soluble vitamin, vitamin C is involved in protein metabolism, is an antioxidant and is critical for the biosynthesis of carnitine, collagen and select neurotransmitters.As an important part of connective tissues, vitamin C assists in wound healing and supports joint health.

Vitamin E: 40 IU –A collective name for eight different, naturally-occurring chemicals, Vitamin E contains antioxidant properties that protect the body cellular damage. Vitamin E also supports immune function and stops the damaging effects of reactive oxidative species (ROS) during fat oxidation.5

Vitamin B6: 20 mg –  Required for over 100 metabolism enzyme reactions, vitamin B6 is an essential, water-soluble nutrient important for overall health.In the body, vitamin B6 helps break down proteins, regulate blood sugar, make antibodies, maintain nerve function, and produce hemoglobin which carries oxygen to tissues.5

Vitamin B12: 50 mcg – Vitamin B12 is an important nutrient that helps the body make red blood cells, DNA synthesis, and contributes to nerve functions.A deficiency in vitamin B12 can lead to anemia, a form of chronic fatigue that can lead to weakness or cognitive difficulties and impair performance in the gym.6

Creatine Monohydrate: 3 g – One of the most popular supplement pre workout ingredients, Muscle Pharm Assault’s creatine monohydrate is a potent form of creatine often used in clinical trials. Creatine is a molecule that can quickly produce energy in the body during periods of stress.Creatine monohydrate is well-known for its strength-enhancing effects.

Did you Know: Carnosine levels are predominately determined by the availability of beta-alanine in the body.8

CarnoSyn Beta-Alanine: 1.75 g – A patented form of beta-alanine, Caronsyn is a modified version of the amino acid alanine. Beta-alanine acts as a precursor to carnosine, a molecule which acts as a buffer for lactic acid buildup in the muscles. Supplementing with beta-alanine can also improve lean muscle mass, and may have anti-aging properties8

Betaine Anhydrous: 1.5 g – Betaine anhydrous, also known as trimethylglycine (TMG), is a naturally occurring substance that’s involved in liver function, carnitine production and cellular reproduction.9

Taurine: 1 g –  Taurine is a naturally occurring amino sulfonic acid which helps the body maintain heart and blood health. It also has been shown to enhance fat oxidation during periods of exercise and contributes to antioxidant defense systems.10 During times of stress, the body makes use of large concentrations of taurine found in the skeletal muscles and brain.10

L-Glycine: 1 g – A nonessential amino acid, L-glycine is critical for the formation of creatine in the body, as well as constructing DNA and RNA.12 Glycine also functions as a neurotransmitter, regulates blood sugar levels, and controls the amount of glucose that’s delivered to skeletal muscles. Additionally, glycine is one of the main components of collagen, which is important for maintaining healthy tissues, ligaments, and skin.12

Caffeine Anhydrous: 250 mg – Caffeine is a widely-consumed stimulant known for its ergogenic (performance-enhancing) effects on the central nervous system.13 Caffeine anhydrous is a dehydrated form of caffeine considered by some to have more prominent effects.

Did you Know: Muscle Pharm Assault carries the Informed-Choice seal. Informed-Choice is a voluntary, quality assurance program for sports nutrition brands and manufacturers. A product bearing this symbol tells customers they are purchasing from a reputable supplement company that value safety and quality control.18

Acetyl-L-Carnitine: 250 mg – A derivative of the amino acid lysine, acetyl-L-carnitine is a compound know to help prevent aging and disease in mitochondria. As well, it can increase mitochondria’s ability to burn fat.14 Supplementing with acetyl-L-carnitine can improve mental alertness, chronic fatigue and preventing neurological degradation. Ongoing research is evaluating its effect on fat oxidation.14

Like many pre workout supplements, Muscle Pharm Pre Workout contains stimulants to delay fatigue and boost exercise endurance. In the Muscle Pharm Assault 30 servings container, each serving will contain 250 mg of caffeine. This is equivalent to approximately 2-3 cups of brewed coffee.15

It also contains a form of caffeine known as pterostilbene caffeine as part of their Energy & Nero Igniter blend. In this product, the amount of caffeine is unknown as it’s a part of a proprietary blend.16

Although Muscle Pharm Assault pre workout is banned-substance tested and bears the Informed-Choice certification, temporary Assault Pre Workout side effects may still occur.

Muscle Pharm Assault side effects

One of the most common muscle pharm assault side effects is a mild, temporary tingling sensation on the skin. This harmless side effect often occurs in doses of 800 mg of beta-alanine or more.

Creatine may cause stomach cramping in some users if it’s not taken with enough water. Nausea and diarrhea may occur when too much creatine is taken at once. To reduce these side effects, users can spread doses out or consume more water.

In the body, creatine helps retain water in muscles. This may lead to minor weight gain in some users. Regular exercise can help combat this side effect.

Assault preworkout contains caffeine, which stimulates the central nervous system to make users feel more alert and awake. In individuals that are sensitive to caffeine, increased jitteriness, nervousness, or irritability may occur.
