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, Supplement Analyst breaks down the 11 Assault Pre Workout active ingredients and explains how they can take your workout to the next level.

Muscle Pharm Assault label
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.3

As an important part of connective tissues, vitamin C assists in wound healing and supports joint health. Vitamin C also contributes to improved absorption for other minerals such as iron.3

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.5

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 mcgVitamin B12 is an important nutrient that helps the body make red blood cells, DNA synthesis, and contributes to nerve functions.6

Vitamin B12 naturally occurs in meat and dairy products. 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.7

Creatine monohydrate is well-known for its strength-enhancing effects. According to a meta-analysis of clinical trials, creatine monohydrate is able to increase a 12% improvement in strength to 20%.7

When combined with a resistance training program, consuming creatine in doses of at least 3 grams can increase power output, strength, lean muscle mass and performance, particularly in anaerobic exercises.7

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.

In studies, beta alanine has been observed to increase muscular endurance in cardiovascular exercises by 60-240 seconds. Supplementing with beta-alanine can also improve lean muscle mass, and may have anti-aging properties.8

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

Additionally, its involved in metabolizing homocysteine, an amino acid which in high levels has been associated with atherosclerosis (hardening of the arteries), heart attack and stroke.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

In a 2012 study published in “Amino Acids,” researchers investigated the ergogenic benefits of taurine on running performance. The double-blind, randomized, crossover design gave participants 1 g of taurine two hours prior to a 3-km time trial run.11

1 g of taurine shown to improve time in 3km timed run. Assault Muscle Pharm pre workout contains 1 g of Taurine in each serving.
Supplementing with 1 gram of taurine (the same amount found in Assault Pre Workout) significantly improved athletes time by 1.7% in 3km timed run.

Volunteers who supplemented with taurine saw significant improvements in time it took to complete the timed runs. Heart rate, relative oxygen uptake and blood lactate did not appear to be affected. Although the mechanisms of action remains unknown, taurine demonstrates potential to positively influence exercise metabolism.11

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 mgCaffeine 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.

In clinical trials, caffeine has been shown to increase power output, delay fatigue and contribute to enhanced anaerobic cardiovascular capacity.  Caffeine also appears to increase the rate of metabolism and fat oxidation, which can both contribute to weight loss.13

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

Muscle Pharm Assault Caffeine

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

While the muscle pharm assault 50 servings is no longer available on the Muscle Pharm website, it can still be purchased online or from various supplement retailers. 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

Muscle Pharm Assault Side Effects

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.

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.
