Mutant Stimutant Review

Mutant Stimutant

If you’ve already got the muscle, but it’s hibernating under a few too many layers of fat, Mutant Stimutant wants to make you a customer.

A supplement advertised to offer “freaky peeled-to-the-bone definition,” Mutant Stimutant is a fat burner meant for dedicated athletes and bodybuilders. With natural ingredients, Stimutant is said to give you the push you need to shed extra fat and improve body composition.

Is Stimutant really the best solution to your fat loss needs? I intend to find out by looking into this supplement further.

Who Makes Mutant Stimutant

One thing you always want to consider with a prospective supplement is who makes it. Learning about the manufacturers prepares you for what business practices to expect, and even gives you a clue about the quality of the company’s products.

The Mutant line is manufactured and sold by Fit Foods Ltd., a supplement company based in Port Coquitlam, British Columbia. One nice thing about dealing with international companies is that they usually tell us more about themselves than companies based in the U.S., and that’s certainly the case with Fit Foods.

Fit Foods was founded in 1996 by CEO Jim McMahon and now owns 7 brand names, including Mutant. Other popular brands include PVL Essentials, North Coast Naturals, and Whey 2Good. These supplement lines sell in more than 70 countries.

According to the company website, Fit Foods also runs events and programs designed to encourage positive eating behaviors and teach people about alternatives to fast food.

The Fit Foods manufacturing plant is licensed by Canada’s Natural Health Products (NHP) legislation, and has a license from the Canadian Food Inspection Agency (CFIA).

Another good thing about Canadian companies is that the CFIA inspects NHPs before they’re sold. This doesn’t guarantee effectiveness, but it does guarantee that supplements aren’t harmful. Conversely, in the U.S., the FDA only takes action against dangerous supplements after many complaints have been received.

Judging by the long and successful history of Fit Foods, I’d say this company is an honest, efficient, and safe one. However, I can’t yet say if their products are just as impressive. To judge that, we have to take a look at the Mutant Stimutant formula.

What’s in Stimutant?

Stimutant is sold in 2 formulas: a U.S. version and an international version. You can purchase either version, but you’ll need to go through another retailer as doesn’t sell U.S. versions to Canadians or vice versa.

The difference between each version is 5 ingredients. The U.S. version contains ingredients that can’t be sold in Canada and other parts of the world, so the international version substitutes these ingredients for others.

As you can imagine, there are benefits and drawbacks to each approach. The U.S. version is likely stronger, but is also more likely to cause side effects. Conversely, the international version is safer but may not perform as well.

I’ll go over the U.S. version in its entirety, and then highlight the changes in the international version. Each version is based on a 399 mg proprietary blend.

U.S. Version

Caffeine Anhydrous

The most common stimulant, caffeine anhydrous is caffeine with excess water removed to enhance potency. It improves metabolism and triggers fat burning by stimulating the central nervous system. This produces heat and speeds metabolic function to increase caloric expenditure. In a 1994 study, caffeine helped overweight and obese women decrease their BMI and improve their metabolism [1].

DiCaffeine Malate

Dicaffeine malate is caffeine fused with malic acid. This increases absorption, which speeds the rate at which dicaffeine malate takes effect. It also decreases side effects associated with caffeine.

Beta-Phenylethylamine (PEA)

Known as PEA, this ingredient is an organic compound that not only builds muscle but improves mood. PEA improves serotonin production, which decreases stress and anxiety. This ingredient is great for overweight people who struggle with feelings of depression and low self-esteem, but seems unnecessary in a fat-burning supplement for bodybuilders.


This ingredient is directly related to PEA. An alkaloid linked with PEA, hordenine is believed to trigger greater action in the central nervous system. However, there are no human trials verifying this effect. Animal studies also show an increase in blood pressure, which may be worrying.


Yohimbe is yet another powerful stimulant. It works much like caffeine anhydrous and dicaffeine malate, raising the body’s internal temperature and burning fat. In a 1991 study, subjects taking yohimbe lost an average 7.82 pounds [2].

Nicotinic Acid

A form of vitamin B3, nicotinic acid regulates fats and sugars in the body to maintain healthy cells. With more vitamin B3, your body should be better able to keep fat levels and cholesterol in check.


Piperine is the combination of black and white pepper. It primarily fights nausea and stomach pain. This may combat some side effects associated with other ingredients in Stimutant, but it doesn’t seem like a necessary extract to include.

International Version

Coffee Arabica Extract

The weight loss benefits associated with coffee are actually the same benefits associated with caffeine. As a stimulant, coffee increases the metabolic rate and accelerates fat burning. However, unlike your morning coffee, this extract doesn’t come with the unwanted calorie increase.

Green Coffee Bean

Green coffee contains 4 times more caffeine than coffee extracts like coffee. This makes its stimulant powers even stronger. In one study, green coffee helped test subjects lose an average of 17 pounds over 12 weeks [3].


A favorite of diabetics and dieters alike, grapefruit controls blood sugar levels and suppresses appetite. These effects were tested in a 2006 study in which subjects who ate half a grapefruit with each meal lost .3 more pounds than subjects who did not [4]. However, these results were very modest and barely statistically significant.

Theobroma Cacao

You know this ingredient better as cocoa. Cocoa contains several antioxidants that lower blood pressure and fight free radicals that cause disease and other health conditions. Cocoa also has weight loss properties. In a study involving rats, cocoa lowered body and fatty tissue weight in rats fed cocoa [5].

Sprouted Barley

While the other ingredients in Stimutant burn fat, barley suppresses appetite. The fiber in barley delays gastric emptying, which keeps you feeling full and less likely to overeat. This prevents you from undoing your good work by eating too much.

The international version, like the American version, also contains piperine and nicotinic acid.

These are powerful ingredients, and many are proven to trigger fat burning. However, with such a small proprietary blend, I’m not convinced they’re included in their proper doses. This could seriously compromise Stimutant’s effectiveness.

Can Stimutant Cause Side Effects?

As you can imagine, the U.S. version has a higher risk of side effects than does the international version. However, the side effects of each are similar.

Because each formula relies on stimulants, Stimutant could cause:

• Headache
• Stress/anxiety
• Nausea
• Vomiting
• Rapid or irregular heartbeat

These side effects are more likely and more likely to be severe in the U.S. version due to its inclusion of yohimbe. This ingredient is considered “possibly unsafe” by WebMD and is linked to reports of heart attack, seizure, and kidney failure.

The most common side effect, however, is anxiety. In fact, many scientists studying this condition give yohimbe to study subjects to induce anxiety.

If you are stimulant-sensitive, I’d recommend avoiding the U.S. version of Stimutant for these reasons.

How Much Does Stimutant Cost?

If you’re buying in the U.S., a 90-capsule bottle of Stimutant costs $49.99. Because each serving is just 1 capsule, this bottle lasts a month and a half. This is a pretty good deal for a muscle-building supplement.

The international version, however, may be more difficult to find. It looks like the product is sold out on, and none of the third-party retailers on the website sell Stimutant.

If you’re interested in the international version of Stimutant, you may want to contact Fit Foods and ask about its availability.

Should You Try Mutant Stimutant?

If you’re not sensitive to stimulants and can find a retailer for Mutant Stimutant, it might not be a bad choice. However, given the small size of the proprietary blend, I’m not sure this supplement delivers results as intense as those they describe. Keep that in mind when trying Mutant Stimutant.
