Mutant Mayhem Reviews

Mutant Mayhem

Pre-workout supplement Mutant Mayhem promises to help you “smash every weight in the gym” while enjoying a “killer instinct intensity.”

Sounds pretty exciting, but can Mutant Mayhem deliver or should it belong back on the shelf?

Is Mutant Pump Backed by a Trustworthy Manufacturer?

The Mutant brand is owned and manufactured by Fit Foods, a Canada-based limited liability company with more than 17 years in the business.[1]

Active in 70 countries around the world, Fit Foods produces and sells various products, as well as provides services for other companies. The company is established, easy to contact, and appears dependable.

What About the ingredients?

To help you perform in the gym and develop more muscle mass, Mutant Mayhem provides various vitamins and an enormous 18,000 mg proprietary blend. The eight most prevalent ingredients in the blend are:

Power Strength Complex (3400 mg)

Waxy maize starch is a corn starch found in many sport nutrition products. Many people believe this ingredient is digested and absorbed quickly, providing the body with rapid energy. However, clinical studies find that while waxy maize starch is absorbed rather quickly, its energy is not used until much later.[2]

In other words, waxy maize starch won’t provide energy until after the workout.

Creapure creatine monohydrate is a patented version of creatine. Many bodybuilders use creatine for better performance and better muscle development. Creatine is a natural substance that turns into creatine phosphate in the body. Creatine phosphate in turn helps produce adenosine triphosphate (ATP) which provides energy for muscle contractions.[3]

Various clinical studies have found that creatine does indeed boost athletic performance and builds lean muscle mass.[4]

L-arginine HCL is an amino acid that is a chemical precursor to nitric oxide. Nitric oxide is a vasodilator, meaning it improves cardiovascular functions and speeds blood and oxygen delivery to muscles.[5]

L-arginine also helps build proteins and speeds up lean muscle tissue development and repair.

Carnosyn beta-alanine is a patented form of beta-alanine, an amino acid that helps build proteins and lean muscle mass.[6]

Hyper-Stim Matrix (2,960 mg)

Micronized taurine is an ingredient often found in energy booster products. Taurine is an amino acid important to muscle growth and various brain functions. While it does help improve vasodilation, its effect on mental performance remains unclear. The micronized version of taurine speeds its absorption.[7]

Glucuronolactone is a naturally occurring ingredient often found in energy drinks with the belief that it works as a stimulant. However, there are no clinical studies supporting this belief.

Pyroglutamic acid is an amino acid that stimulates mental activity by facilitating transmissions between neurons. A clinical study also found that this ingredient helps protect neurons from injury.[8]

L-tyrosine is another amino acid important for brain stimulation. It helps build various neurotransmitters that facilitate nerve cell communication.[9] It is also helps produce hormones like adrenaline.

In all, these eight prominent ingredients are a mixed bag. While many ingredients, like creatine, are proven to boost energy, others’ effectiveness is doubtful.

Plus, these ingredients are included in one blend which makes it difficult to tell if the overall formula actually works.

Are There Side Effects?

Many of the ingredients in Mutant Mayhem can cause side effects if taken in high enough doses. Take the various amino acids that Mutant Mayhem contains, for an example. They can actually become toxic and cause damage to cells and organs.

Also, creatine can cause stomach pain, nausea, and muscle cramping. If taken in high doses, creatine can even damage the liver, kidneys, and the heart.

How Do You Take It?

Since Mutant Mayhem is a powder, mix one scoop with 8-12 ounces of cold water and drink it 10-15 minutes before training.

What About the Price?

Mutant Mayhem can be purchased online from various England and Canada-based vendors. The best prices we found include:

• TropicanaFitness.com: $42.36 for one tub
• TheSupplementStore.co.uk: $42.52 for one tub (720 grams)
• SupplementCentre.com: $37.83 for one tub

Is Mutant Mayhem Backed by a Guarantee?

Mutant Mayhem is not backed by a manufacturer guarantee. However, some of the listed vendors do provide limited guarantees on the products they sell.

Final Thoughts

Mutant Mayhem has an impressive list of ingredients but many of them are unproven. Given the questionable effectiveness of the product, possibility of side effects, and lack of guarantee, we cannot recommend Mutant Mayhem.

We suggest you try a different, more proven pre-workout supplement before trying Mutant Mayhem.

    Hi, first of all. Mutant mayhem gives you amazingly scary results. Almost like “Juicing”. I’ve tried it for about 2 weeks and i can feel my strength increasing tremendously. I bought and tried it without actual research. I’m now concerned over my fast increasing arm size and weight. I’ve been working-out almost 3 years this coming November and after trying this product, i really do see the big difference. I finally did some researching after 2 weeks and found out that this product is banned in some countries. This product is banned for all fitness model competitions and now i know why. Would really recommend people not to buy it as the risks might be great. Now i’m doubting myself as a 100% natty.
