What You Need To Know About Nutrabolics Semtex

Nutrabolics Semtex is mainly a weight loss supplement that works by supporting several biological processes. It uses multi-phase fat loss technology to help you gain lean muscle mass. It is also supposed to reduce sugar cravings and hunger pangs, which in turn will help you perform better in the gym and lose weight more effectively. It uses mild stimulants, such as Teacrine to increase energy and offer nootropic benefits. It is quite similar to caffeine but works without making you deal with jitters or energy crashes. It also contains Dendrobium, which is also a nervous system stimulant, and helps improve your mood. Phenylethlamine is also known for its concentration and mood enhancing properties. Then, there is another stimulant called Theobromine. While you may feel alert and be able to perform better in the gym after taking Nutrabolics Semtex, you may end up experiencing several side effects too. For many people, Nutrabolics Semtex is too heavy in stimulants and is therefore not suitable for you.

What Are The Side Effects Of Nutrabolics Semtex?

Nutrabolics Semtex contains several stimulants, so it is quite natural to develop some side effects, such as increased heart rate, high blood pressure, restlessness, and insomnia. Refer to our “Side Effects” section to learn more.

How Much Does Nutrabolics Semtex Cost?

You have to pay $39.99 to get a pack of 90 capsules.

Our Verdict On Nutrabolics Semtex

Nutrabolics Semtex claims to increase energy and fat loss. It also supports better memory and cognitive function. It certainly includes some popular ingredients, but it seems that it relies heavily on stimulants. You get Dendrobium, caffeine, Theobromine, and Theacrine that stimulate your nervous system to increase energy. The truth is that these stimulants only mask the signs of fatigue, and you eventually end up dealing with a fatigued crash. The stimulants also increase your metabolism, but it may not lead to a significant weight loss. It contains diuretics that may reduce water weight, but that is not weight loss in the true sense. Moreover, the price of Nutrabolics Semtex is on the higher side, especially considering the fact that you can easily get these stimulants from other relatively cheaper supplements. Therefore, it is better to avoid putting your money on this supplement.

Overall, we do not recommend Nutrabolics Semtex to our readers.

Nutrabolics Semtex Review

Nutrabolics Semtex is advertised as a powerful weight loss supplement because it reduces your appetite, boosts your metabolism, and supports energy production. Many people also take it as a bodybuilding supplement mainly because it contains a number of stimulants. The problem is that taking a supplement loaded with stimulants can cause several side effects. Moreover, many of the ingredients found in Nutrabolics Semtex do not have enough scientific evidence for support.

First up, there is Teacrine in Nutrabolics Semtex. With properties similar to caffeine, it stimulates your central nervous system to promote alertness. You certainly get a good dose of Teacrine from Nutrabolics Semtex, but you may end up experiencing several side effects as well. Supplement manufacturers say that you are less likely to experience energy crashes with Teacrine, but not many studies are there to support this claim. It is also thought that Teacrine may help improve cognition and mental health, but again, studies are not there to support it. For instance:

  • One study in humans found that TheaTrim had no effect on two measures of cognition and working memory (Digit Symbol Substitution Test and Trail Making Test) when ingested immediately before the testing battery compared to both placebo and 150 mg caffeine controls (Source). TheaTrim is a proprietary blend of theacrine (amount unspecified due to its proprietary nature), 150 mg caffeine, white willow bark, S-Adenosyl Methionine, Rauwolfia vomitoria extract, citrus bioflavonoid complex, and vitamin B12. However, subjective reports of attentiveness, focus, and alertness trended toward statistical significant for the TheaTrim group (Source). These effects cannot be definitively attributed to theacrine, however, since the supplement did not contain pure theacrine alone, but a host of other ingredients.

Human studies have not found any significant effects either. For instance:

  • A proprietary blend of supplements containing both theacrine and caffeine may improve subjective feelings of grogginess. However, this putative effect cannot be attributed to theacrine alone since the blend contained a host of other supplements. Source

Nutrabolics Semtex Facts

  • Natural ingredients
  • Improved focus

There is another stimulant found in Nutrabolics Semtex – it is called Dendrobium. It is mainly a nootropic and works by stimulating your central nervous system. It is also supposed to work in conjunction with phenylethylamine to improve mood and increase energy production. You get 600mg of Dendrobium from each serving of Nutrabolics Semtex, but the problem is that it does not really help with energy production but it only masks the signs of fatigue. You will feel alert for a short while but then eventually experience energy crash. It is worth mentioning that some bodybuilders take Dendrobium because it is supposed to work like a banned substance called DMAA. You should avoid DMAA because it constricts blood vessels and leads to problems like increased heart rate, high blood pressure, and an increased risk of heart attack. Therefore, it makes sense to avoid Dendrobium as well. If you are really interested in taking the risk, you need to ensure that you are taking enough of it on a daily basis. For instance, you get 600mg per serving, but you should be taking up to 6,000mg to see any effects. It is severely under-dosed in Nutrabolics Semtex, which is why you are not going to see any significant mood and energy enhancing benefits.

It is worth mentioning that some experts are of the view that because Dendrobium is a combination of several alkaloids, it is supposed to help you lose weight and cognitive benefits as well. Unfortunately, you will not find enough scientific evidence to support these claims. The presence of PEA or Phenylethylamine does not make Nutrabolics Semtex any better. PEA is supposed to increase energy production and improve mood by affecting neurotransmitters in the brain. Some studies show that it may help suppress appetite, but it is not going to lead to a significant reduction in weight. It may help reduce depression symptoms though. For instance:

  • A study published in the “Journal of Neuropsychiatry Clinical Neuroscience” in 1996 showed that phenylethylamine is effective in treating depression. The tolerance developed from amphetamine use, which leads to a need for increasing dosage, doesn’t occur with phenylethylamine. By stimulating the release of dopamine, PEA reduces appetite while improving mood.

How to Take Nutrabolics Semtex

Here is what the official site says about taking Nutrabolics Semtex:

  • Suggested Use Training Days: Take 1 serving (3 capsules) of SEMTEX™ within 1 hour of training. For best results, combine with a diet and exercise program
  • Suggested Use Non-Training Days: Take 1 serving (3 capsules) of SEMTEX™ in the morning with a meal
  • For best results, combine with a diet and exercise program

Nutrabolics Semtex also contains caffeine, which again, is a CNS stimulant. It is supposed to help with weight loss because it increases thermogenesis. It also stimulates your nervous system to keep you alert, which may help you handle your workouts with more intensity. Unfortunately, not many studies are there to confirm if caffeine will prove effective for everyone. The truth is that caffeine is actually a psycho-stimulant and works quite like cocaine, amphetamine, and other similar substances. The effects of caffeine are relatively milder as compared to other psycho-stimulants, but that does not make it any better.

You should also keep in mind that how you react to caffeine varies from person to person. Some people are more sensitive to caffeine and experience immediate effects, while others need to take large doses to notice any effects. Moreover, it may help only when you are already fatigued. For instance:

  • Caffeine ingestion, at 6mg/kg bodyweight, was able to slightly increase Reaction Time, Decision Time, and Movement Time when ingested in either fatigued or fully rested athletes. Source

The problem is that even when caffeine helps increase alertness and reaction time, the effects are not that significant.

  • Smith himself has examined the impact of caffeine on real-life work performance in two ways. The first was what Smith described as an “after-effect” technique, which involves obtaining both subjective and objective measurements both before and after work and using the difference between the before- and after-work measurements as an indicator of performance during the work period. So someone who had a very fatiguing work day would show a much larger after-effect of that day compared to someone who had a relatively light work day. Smith (2005) measured reported alertness and simple reaction time among 110 workers both before and after work and found that workers who had consumed caffeine during the day were more alert and had faster reaction times.

Similarly, some studies show caffeine may increase thermogenesis, but it is not going to lead to a significant reduction in weight.

Nutrabolics Semtex Concerns:

  • Under-dosed, ineffective ingredients
  • Not enough scientific evidence for support
  • Possible side effects
  • Not effective for most
  • Very expensive

After taking Nutrabolics Semtex, you may notice a slight reduction in body weight, but you have to understand that it is not fat loss. The supplement contains Theobromine, which acts as a diuretic. It means that it will help you lose water weight, but you will regain the weight once you return to your normal routine. It may help reduce your appetite, but that happens when you take larger doses. Since you already get a good dose of caffeine from Nutrabolics Semtex, mixing Theobromine could lead to serious side effects.

To enhance thermogenesis, Nutrabolics Semtex also contains cayenne pepper. Again, the effect of cayenne pepper is not going to be huge. It may increase your metabolism a little, but that is not going to translate into a significant reduction in weight.

The fact of the matter is that though several claims are associated with Nutrabolics Semtex, it is not going to prove effective for everyone. You will also have to be careful when taking it, because it is so loaded with stimulants that you may develop some serious side effects. Whether you need help increase alertness or you want something to increase energy to handle your workouts better, you should look for something that does not rely too much on stimulants. Nutrabolics Semtex is not the right choice here!

What Does Nutrabolics Semtex Claim To Do?

Nutrabolics Semtex claims to help you in various ways. Here are some of its claimed benefits:

  • Helps you lose weight effectively
  • Reduces body fat percentage
  • Supports thermogenesis for weight loss
  • Prevents sugar cravings and hunger pangs
  • Supports energy production
  • Increases focus, concentration, and cognition

Does Nutrabolics Semtex Work?

Nutrabolics Semtex claims to help you in many different ways – it lowers body fat percentage, it increases energy production, and it improves mood and concentration. Unfortunately, scientific studies do not support these claims associated with the ingredients found in Nutrabolics Semtex. The supplement contains a number of stimulants, but it is not a good idea to rely on stimulants to feel energized. By stimulating your nervous system, you may be able to handle a strenuous workout better, but you will end up dealing with jitters and energy crashes. Some of its ingredients may lead to an increase in metabolism, but the increase is not enough to cause a significant change in weight. The presence of caffeine, Dendrobium, and Theobromine may also cause several side effects. Therefore, it is a good idea to avoid going for the supplement in the first place. Look for something with scientifically proven fat burners and nootropic ingredients – Nutrabolics Semtex is not going to help!

What Are The Ingredients of Nutrabolics Semtex?

Nutrabolics Semtex is supposed to help you lose weight because it contains several popular ingredients. The problem is that some of its ingredients are under-dosed, while others have many potential side effects. It is a stimulant-based supplement, which is why it is not suitable for everyone. Here is what the official site says about different ingredients found in Nutrabolics Semtex:

  • Dendrobium 600mg: Acting as a central nervous system stimulant, this potent nootropic combines with Phenylethylamine (PEA) to provide a very smooth energy coupled with powerful mood enhancement capabilities.
  • Phenylethlamine 400mg: Increases focus, concentration, and enhances mood. This active ingredient helps to increase the process of lipolysis through stimulating the release of Catecholamine.
  • Caffeine Anhydrous 300mg: Has thermogenic properties that aid in the burning of fats. The presence of caffeine in the body leads to the increase of epinephrine and norepinephrine. These two hormones signal the body to dissolve fat so that it can be available as an energy source.
  • Theobromine 300mg: This active is a mild stimulant and diuretic which can aid in increasing insulin sensitivity. Theobromine also acts as a mood enhancer.
  • Cayenne Pepper 200mg: Increases metabolic rate and thermogenesis while helping to suppress appetite. Increases secretion of Catecholamine.
  • Theacrine (Teacrine®) 200mg: Enhances physical energy by causing adenosine signaling changes similar to caffeine with longer lasting results. It also acts as a dopamine antagonist by causing dopaminergic signaling, which enhances physical energy even further.
  • Piperine 10mg: Aids in decreasing the size of fat cells, improves cholesterol levels, suppresses leptin.

Does Nutrabolics Semtex Have Any Side Effects?

Nutrabolics Semtex contains quite a few ingredients, so it is possible to develop some side effects as well. The presence of caffeine makes it bad for people who cannot tolerate stimulants well. It may cause problems like increased heart rate, high blood pressure, restlessness, irritability, mood swings, and sleeplessness. Coupled with Teacrine, Theobromine, and phenylethylamine, caffeine can lead to some serious problems in some individuals. It is important to avoid taking this supplement if you have any underlying condition. You should stay away from Semtex if you are pregnant or breastfeeding.

Are There Any Customer Reviews For Nutrabolics Semtex?

Nutrabolics Semtex is supposed to help you lose weight and get lean muscle mass. However, it seems that it does not have many happy and satisfied customers. For instance:

I felt terrible after taking the supplement. I have tried caffeine in the past, but Nutrabolics Semtex was a bit too strong for me. I do not think it is a suitable choice for most people. Avoid it if you do not want to deal with side effects.

I have been taking the supplement for the last three weeks, but it has done nothing to increase my energy levels. It does suppress your appetite a little, but do not expect a significant reduction in weight though.
