Out of all the weight loss supplements available on the market, fat-burners have to rank as the most eye-catching. Often sold with the promise that they can drop pounds with minimal effort, these products tend to work by loading up the body with stimulants that force it to work even whilst resting. But is the weight loss worth the heart-pounding side effects?

Below we take an in-depth look into Jetfuel, to see whether this stimulant-based weight loss supplement is as effective as it seems.

Jetfuel Pros

  • Contains several effective ingredients

Jetfuel Overview

What You Need To Know About Jetfuel

Jetfuel is a weight loss supplement that mixes together dozens of stimulants ingredients, nootropics, and amino acids. It remains one of the cheaper weight loss supplement available to buy online, and comes in a jumbo-sized box packed with 120 capsules.

What Are The Side Effects Of Jetfuel?

This product contains a heavy mixture of stimulants, many of which combine to create pretty severe side effects. Click on the Side Effects tab for the full list!

Customers using this product should expect to experience jitters, heart palpitations, high blood pressure, headaches, irritability, and sleeplessness, especially if you are sensitive to stimulants.

How Much Does Jetfuel Cost?

The cheapest price we found available online was on Amazon, where a month’s supply costs just $18. In many other online stores (including the official GAT Sports website), the same pack tends to retail for around $25.

Our Verdict On Jetfuel

Products like Jetfuel are hard to review, as it remains impossible to know how well they work. The manufacturers have made every effort to confuse customers by flooding the Amazon review section with fake comments and hiding vital ingredient quantity information.

The unfortunate conclusion is that it’s hard to work out whether this extraordinarily-cheap product works. It certainly contains some effective ingredients, but also attempts to stuff dozens of them into each tiny capsule. It’s possible that the dosages are too small to be truly effective, which may be a blessing given the unpleasant nature of side effects caused by stimulant ingredients like these.

The price may be good, but this is ultimately a product that comes accompanied with too little information, too many potential side effects, and no money-back guarantee to protect purchases.

Overall, we do not recommend Jetfuel to our readers.

Jetfuel Key Features

Jetfuel is a weight loss supplement that claims to be appropriate for athletes, fitness enthusiasts, bodybuilders, and ordinary dieters. It works by providing customers with a significant burst of energy to support fat-burning thermogenesis, and to provide fuel for longer and more intense workouts.

Jetfuel Facts

  • Manufactured by GAT Sports
  • Contains 120 oil-infused capsules per bottle
  • Energy-boosting weight loss supplement

Jetfuel is manufactured by GAT Sport, a sports and nutraceutical company that was founded in 1997. GAT Sports appears to be a joint American-German initiative, and the company is mainly known for the many professional athletes it uses to promote its products. The company hit headlines when one of its flagship athletes, UFC fighter Jon Jones, was banned for using banned performance-enhancing drugs, which he later blamed on “tainted supplements”. Though they were likely not at fault, this forced the company to issue a statement that Jones’ rule-breaking was not committed whilst using one of their products. The company can be contacted via the contact form provided on their official website.

How to Take Jetfuel

The directions for use are as follows:

Take 1 serving (3 capsules) 1-2 times per day. Take 1 serving first thing in the morning. JETFUEL can be taken with or without food depending on your stomach sensitivity. If you are sensitive to caffeine, do not take within 6 hours of bedtime.

Jetfuel Concerns:

  • Ingredient quantities not listed on the packaging or on the sale website
  • Many of the positive customer reviews on Amazon appear to have been faked
  • No money-back guarantee

What Does Jetfuel Claim To Do?

Like many of the other fat-burning supplements out there, Jetfuel claims to help dieters metabolize fat more effectively, whilst also suppressing appetite and providing a sharp burst of energy. Some of the other ingredients included within the mix are said to improve mood and sharpen focus.

Does Jetfuel Work?

GAT Sports fail to disclose the ingredient quantities used in this product, which makes it impossible to estimate how well it works. In addition, many of the customer reviews posted on Amazon appear to have been outright faked.

This product contains many of the ingredients needed to provide a fat-burning, energy-boosting effect, and there are also some ingredients that could sharpen focus. However, without the right information, it’s not possible to know how well Jetfuel works.

What Are The Ingredients of Jetfuel?

The ingredients found in Jetfuel are listed below. Unfortunately, the manufacturers fail to disclose the ingredient quantities used in this product, which makes it impossible for customers to know whether each ingredient has been dosed correctly. The few quantities listed are correct for 3 capsules.

  • Niacin (as Niacinamide) 25.5mg (128% DV): This vitamin is normally only useful in cases of deficiency, although very high doses (like that which is used in this product) have been associated with lowering cholesterol. Source
  • Vitamin B12 (as Cyanocobalamin) 360mcg (6000% DV): Vitamin B12 has several roles in the body, including helping to release energy from consumed food and keeping the nervous system healthy. It may be that a deficiency hinders weight loss. Source

JETFUEL Concentrated Thermogenic Blend 1036mg

  • Dimethylaminoethanol (DMAE) Bitartrate: This ingredient is marketed as a memory and mood enhancer, as it is a major chemical component of choline, and supplementation increases acetylcholine, a compound associated with memory. However, it is not known whether this applies when DMAE is used by cognitively-healthy people. Source
  • Caffeine Anhydrous: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive. Source
  • Guarana Seed Extract: This berry is naturally high in caffeine, and it is often an ingredient used in energy drinks and diet pills. Source
  • Medium Chain Triglycerides Complex (MCT) Oil Powder: Athletes sometimes use MCTs for nutritional support during training, as well as for decreasing body fat and increasing lean muscle mass. However, scientifically speaking, there is not enough evidence to say that MCTs are effective in decreasing fat mass or increasing muscle mass. Source
  • American Ginseng Root: This ingredient is often thought of as an adaptogen, helping to boost the immune system and improve general health. Studies, mostly in animals, have also suggested that it can lower blood sugar levels, reduce the severity of colds, aid relaxation, and enhance cognition. Source
  • Bitter Orange Fruit Etract (Advantra Z Citrus Aurantium 6% Synephrine): Bitter orange peel has been proven to raise the metabolism and aid weight loss. It contains numerous stimulant compounds, including synephrine. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it. Source
  • Yohimbe Bark Extract (8% Yohimbine): Some studies have noticed increased blood concentrations of free fatty acids in participants who use yohimbine 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. Source
  • Green Tea Leaf Extract: Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins and caffeine both increase energy expenditure by boosting the metabolism temporarily. However, the metabolic increase caused by green tea is limited. Source
  • Sodium Starch Glycolate (Explotab): This starchy mixture is designed to expand when it comes into contact with water. Source
  • Phosphatidyl Serine (from Soy Lecithin): Studies and the FDA claim that Phosphatidylserine may reduce the risk of cognitive dysfunction and dementia in the elderly. Source
  • Acetyl-L-Carnitine HCl: There is some evidence that supplementation of acetyl-l-carnitine can reduce body fat, although the strongest results were seen in the elderly. The ingredient also boosts energy levels, and is used to treat fatigue. Source
  • Rhodiola Root Extract: Rhodiola Rosea appears to improve endurance (as proven in rats), and it also appears to help stave off fatigue. It is not proven to work as a nootropic in non-fatigued consumers, but it does appear to provide limited cognitive benefits to consumers who are fatigued. Source
  • Hoodia Gordonii Stem Extract: This plant extract was eaten traditionally in the South African bush to stave off hunger. There is little clinical evidence to actually prove that it works as an appetite suppressant, and far more studies that show that the product is ineffective and unsafe, frequently causing a wide range of side effects. Source
  • c-Amp (Cyclic Adenosine 3-5 Monophosphate): Within the body, cAMP is known to affect numerous cellular processes, including the metabolism of carbohydrates and fats. It is not known whether supplementing it has the same effect. Source
  • E&Z Guggulsterones (GuggulEZ-100): In some studies, it has been suggested that guggul can reduce the impact of insulin resistance. However, these same studies claim that these effects are not the work of guggulsterones, which do not have the same effect.
  • Magnolia Bark Extract: Magnolia is sometimes used to treat anxiety, and one study suggested that it may have weight loss effects (as it may have reduced stress-induced eating). Source
  • L-Theanine: This amino acid is found in green tea and may increase feelings of relaxation without drowsiness. Source
  • 5-HTP (from Griffonia Seed Extract): 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood. Source
  • Black Pepper Fruit Extract (BioPerine) 5mg: This patented 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. Source

Does Jetfuel Have Any Side Effects?

With so many ingredients, it should be no wonder that Jetfuel is linked with so many potential side effects.

The combination of bitter orange peel, bioperine, and caffeine used by this product is known for its habit of causing side effects. Potential adverse effects include heart palpitations, high blood pressure, jitters, sleeplessness, headaches, and irritability. It’s worth taking these risks seriously – bitter orange peel has actually been linked with the onset of strokes and heart attacks in otherwise healthy patients.

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

In one study into Hoodia, participants reported a high number of side effects, which included headaches, nausea, vomiting, ‘odd skin sensations’, increased blood pressure, and increases in heart rate. There were also signs of liver damage in some of the participants.

The many remaining ingredients found in this product can also include other side effects, including constipation, depression, vivid dreams, schizophrenia symptoms, breast tenderness, vaginal bleeding, and more.

Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. If you are taking any medications or are unsure about the suitability of this supplement for you, consult your doctor before purchase.

Are There Any Customer Reviews For Jetfuel?

Many of the reviews posted to Amazon discussing Jetfuel are positive. However, we checked the reliability of these reviews with the review-checking service at FakeSpot, and unfortunately found that nearly half of the positive reviews are estimated to be fake. The opinions of those that remain appear to be split down the middle.

This is hands down the best thermogenic I’ve ever used. Curbs cravings, helps with my appetite, and doesn’t make me feel like my skin is going to crawl off.

This stuff seems pretty good…not sure why it makes me poop so much (sorry tmi) but I definitely can feel a difference.

I can honestly say I haven’t lost an ounce on this fat burner.

Not a fan- Minimal energy gain, no other noticeable side effects

Does Jetfuel Offer a Money-Back Guarantee?

GAT Sports do not offer a money-back guarantee to customers. Customers are able to return any product within 30 days, but will only receive a refund if their products are returned unused in a re-saleable condition.
