What You Need To Know About Mutant Stimutant

We have mixed feelings about Mutant Stimutant. The customer reviews are generally positive, but there are some consumers who noticed no beneficial effects. Also, the manufacturer does not state the individual ingredient quantities, which makes it more difficult to establish the strength of the product and the likelihood of side effects occurring.

What Are The Side Effects Of Mutant Stimutant?

There are ingredients that could be effective at aiding weight loss, such as caffeine and Hordenine, but several of the ingredients, such as Yohimbe, often cause a range of side effects, some of which can be unpleasant. There is a huge list of restrictions on who should not use the product as well.

How Much Does Mutant Stimutant Cost?

Mutant Stimutant costs $29.99 when ordered from the official website.

Our Verdict On Mutant Stimutant

There is no money back guarantee offered by the manufacturers; their returns policy only covers unopened products for 15 days after the purchase date, which isn’t great. Plus there are a lot of side effects. So overall, we do not recommend Mutant Stimutant to our readers.

What Does Mutant Stimutant Claim To Do?

The manufacturers of Mutant Stimutant provide the following description of the benefits of the supplement:

  • Stimulates fat shredding
  • Ignites hellfire focus and intensity
  • Supports peeled-to-the-bone definition
  • Cranks you up higher and longer than ever!

Does Mutant Stimutant Work?

Some of the ingredients used in Mutant Stimutant could potentially aid weight loss, such as Caffeine and Hordenine. These work as stimulants, boosting the metabolism to burn extra calories and increase energy levels. Caffeine has a lot of clinical support, but its effects are considered ‘small but significant’. Hordenine is less well-studied on its own; it is found in Bitter Orange, and is a known stimulant, but studies tend to focus on other active compounds found in Bitter Orange that are not used in this supplement.

Hordenine and Yohimbe may aid weight loss, but they are also likely to cause side effects, some of which can be unpleasant and serious.

PEA appears to affect alertness, and to benefit mental function and mood in general.

The customer reviews for Mutant Stimutant are generally very positive, with only a few customers failing to notice any positive changes.

Overall, it does appear that Mutant Stimutant could aid weight loss by boosting the metabolism, but only if the consumer does not experience any of the numerous potential side effects that would stop them from taking the product.

What Are The Ingredients of Mutant Stimutant?

The ingredients used in Mutant Stimutant are detailed below. The individual ingredient quantities are not listed, as the product contains a proprietary formula. The quantities that are listed are per single capsule serving.

  • Niacin12 mg (60% RDA): Vitamin B3, or Niacin, is responsible for helping to produce energy from consumed food, as well as helping keep the nervous and digestive systems healthy. Niacin can be easily sourced in adequate amounts from a balanced diet. Persistent excessive consumption of niacin has been linked with increased rates of obesity in American Children.
  • Stimutant Proprietary Blend376 mg
    Dicaffeine Malate (99%):
    caffeine combined with Malic acid. Provides increased energy as well as increasing thermogenesis in the body.
  • Caffeine Anhydrous (99%): Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
  • Naringin (98%): A compound found in grapefruits that accounts for its bitter taste, it is known to extend the amount of time that caffeine remains in the body. This would make the effects of caffeine also last longer. Research also suggests that Naringin enhances lipid (fat) metabolism in the body, which again could have positive implications for dieters.
  • Beta-Phenylethylamine (98%): More commonly referred to as PEA. This ingredient is derived from the amino acid phenylalanine. It is thought to increase alertness, aid in concentration and focus, and may also enhance mood, which are all arguably traits that dieters need help with in succeeding with their weight loss attempts.
  • Hordenine HCL (98%): Hordenine is a known compound in Bitter Orange, and is thought to act as a stimulant to increase fat burning.
  • Yohimbe HCL (98%): Some studies have noticed increased blood concentrations of free fatty acids in participants who use yohimbe extract, suggesting increased rates of lipolysis. However, the Natural Medicines Comprehensive Database has stated that there is insufficient evidence to claim it aids in weight loss.
  • Nicotinic Acid (98%): Nicotinic Acid is more commonly known as Niacin. (See above.)
  • Piperine (95%): This Black pepper extract is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects.

Does Mutant Stimutant Have Any Side Effects?

The manufacturers have not listed the individual ingredient quantities used in the supplement, which makes it more difficult to establish how strong and effective Mutant Stimutant really is.

This product contains several stimulant ingredients that have been proven to increase the body’s metabolic rate and therefore burn more calories. Hordenine is a stimulant ingredient that could increase energy levels (both physically and mentally) as well as increasing the consumer’s metabolic rate. Caffeine has similar effects, but is generally much less potent, with results from clinical trials being considered as ‘small but significant’.

Yohimbe could also potentially aid weight loss, although the supporting clinical evidence is more mixed. The ingredient can also cause a large range of side effects.

Piperine increases the absorption of caffeine and other compounds from the digestive tract into the bloodstream; this effectively makes the doses used higher, but can increase the chances of side effects occurring and increase the chances of accidental overdose from prescription medication.

Naringin is thought to increase lipolysis (one type of fat burning) in the body. It also extends the amount of time that caffeine stays in the bloodstream before being broken down. This makes it even more important to avoid taking the product in the evening, as it could cause sleep disturbances due to the continued effects of caffeine.

Does Mutant Stimutant Have Any Side Effects?

There are numerous ingredients used in Mutant Stimutant that could cause side effects. As the manufacturers have not provided the individual ingredient quantities used in the supplement, it is difficult to establish the likelihood of any side effects occurring.

Naringin is typically extracted from grapefruit and could potentially interfere with the absorption of medications, which increases the chances of accidental overdose. Naringin also delays the breakdown of caffeine in the bloodstream, extending the effects of the stimulant ingredient.

Significant quantities of caffeine can cause side effects such as headaches, increased urination, dehydration, jitteriness, increased heart rate, increased blood pressure, heart palpitations and problems sleeping. Consumers should avoid other sources of caffeine whilst taking this supplement to avoid increasing the chances of side effects developing. Consumers should also stay hydrated by drinking plenty of water throughout the day, and should not taking this product in the late afternoon or evening. These measures will minimise the chances of side effects occurring.

Piperine can increase the absorption of caffeine and other stimulants, increasing their effectiveness, but also making side effects more likely. Piperine can also affect the absorption of other medications, increasing the chances of accidental overdose.

Yohimbe can cause a wide range of side effects, including stomach upset, excitation, tremor, sleep problems, anxiety or agitation, high blood pressure, a racing heartbeat, dizziness, stomach problems, drooling, sinus pain, irritability, headache, frequent urination, bloating, rash, nausea, and vomiting. High doses can cause more severe effects.

Hordenine is a stimulant, and so is not suitable for use by those who have heart conditions or elevated blood pressure levels. Stimulants can raise blood pressure, increase heart rate, cause heart palpitations and interfere with sleeping patterns.

Are There Any Customer Reviews For Mutant Stimutant?

There are numerous customer reviews for Mutant Stimutant on, one of the third party retailers who sells this supplement.

WOW. From first pill my body take fire….It gives a lot of energy a lot of sweat at all exercises. ATTENTION: Do not take 3 hours before sleep because u don’t sleep, don’t take it with black coffee at the same hour and don’t take more than 1 at same time u see your breath like cut.. EXCELLENT PRODUCT.

Great product. I use it mainly to get my engine going when I do my morning fasted cardio. This isn’t a super hard hitting stim but it gives you a good push of sustained energy over a period of time. I love it for what I use it for and recommend this product to friends and family!

Very good product. As I am not using regularly caffeine, it would give me great energy and focus throughout the whole workout, helping me reduce the breaks between sets and going higher with the weights. Using it during the summer will make you look like you took a shower while you are working out. It will make you soaking wet, melting over and over. But if there is any place that is ok to be filthy and dirty is in the gym, so you will be in the right place. I also felt like the coiffein levels were a bit too high for me, I was working out at 6pm, so I took a tablet around 5pm, and had insomnias until 2am, not very good if you have to wake up at 8am next day.

It worked the first 2 times I used it giving me more energy, but I lost weight the same as I normally would waste of my 40 dollars if your looking for something to help u lose don’t take this.

I took 1 pill 20 minutes before gym felt nothing, took the 2nd pill total time about 35 mins after first one and still didn’t get hardly anything, I do have a high tolerance to pre workouts and fat burners but expected more … a lot more for now 6/10 – I did have some energy but nothing that can’t be obtained by slamming a monster zero or redbull zero on empty stomach I do LOVE their protein though.

Very disappointed, I’ve been taking these for about 3 weeks now and honestly have no energy boost whatsoever. I use them in the mornings and right before work and nothing, I’m tired all day and wasted $40. Save your money and buy some caffeine pills!
