JetFuel T-300 by GAT Testosterone Booster and Fat Burner Review

GAT has quickly become a big name in the supplement industry, and we have to admit – some of their products are really among the top in their category.

So for this reason, we were excited to test their brand new JetFuel T-300. Which is a testosterone booster with a secondary function of a fat burner.

Let’s take a look at its ingredients and side effects, to see whether this product lives up to GAT’s reputation.

Pros and Cons of JetFuel T-300 by GAT


  • Cayenne pepper is a great thermogenic
  • Ashwagandha helps combat stress


  • Missing Vitamin D3, D-Aspartic Acid, and Fenugreek; all of which boost testosterone
  • None of the ingredients have any significant impact on testosterone levels
  • Contains Yohimbe, Tribulus, and Bitter Orange Peel, known for their harmful side effects
  • Uses zinc with a poor bioavailability


Benefits that GAT claims for JetFuel T-300;

  • Boosts metabolism
  • Increases testosterone

Dosage | How To Use

You should take 3 capsules (1 serving) of JetFuel T-300 1-2 times per day.

We always recommend taking more daily servings, as that will help you keep your testosterone constantly elevated.

But first, we have to see the ingredients to determine whether they’re safe enough to be taken in higher dosages.


One of the most important things to look at when choosing a testosterone booster, is whether it contains any proprietary blend. With JetFuel T-300, we’re happy to report this isn’t the case. All of its ingredients and dosages are clearly shown for you to see.

Other things you should also check are whether the product contains any dangerous ingredients. Unfortunately, this is where JetFuel T-300 starts to raise some concerns. It uses Yohimbe Extract and Bitter Orange Peel, which, despite being natural, are banned in numerous countries due to their harmful side effects.

Ingredient Breakdown

Calcium Fructoborate

While its name sounds fancy, Calcium Fructoborate is just calcium mixed with fructose. It’s not necessarily a bad thing, but it’s not really beneficial either – it doesn’t affect your testosterone levels.

Tribulus Terrestris

Including Tribulus in a testosterone booster is a rookie mistake. It’s an ingredient thought to improve T-levels, which is why countless test boosters use it. But studies keep disputing these rumors, showing it has no real benefits on the male hormone.

But that’s not the worst thing about Tribulus. The main concern lies in its side effects; Tribulus Terrestris is linked to prostate enlargement in men. So unless you’re looking for a urology exam, avoid this ingredient like the plague.

Cayenne Pepper Extract

Cayenne Pepper is one of the best fat burning ingredients you’ll find on the market. It can raise your body temperature, making your metabolism work faster.

Ultimately, this leads to a number of effects; such as an increased heart rate and fat loss. It’s an ingredient that’s safe and it works – can’t argue against that.

Zinc Monothionine

Zinc can help you boost low testosterone if you’re deficient in it, and if you take it in the right supplemental form.

The most bioavailable form of zinc is aspartate. However, GAT have decided for zinc Monothionine in JetFuel T-300, which has a very poor absorption in your body. In other words, it’s useless when you take it orally.


If you’re looking to slightly burn fat, then caffeine is one of the best ingredients you’ll find. It boosts your energy, improves metabolism, and makes your body burn more fat. All of this makes it a good ingredient for someone looking for a fat burner.

However, since we’re reviewing a testosterone booster, this is a pointless nutrient in such product – just like Cayenne pepper. GAT could’ve put another ingredient that would boost your testosterone instead of caffeine here.

Bitter Orange Extract

Okay, now this is one of the worst and most dangerous ingredients in GAT’s JetFuel T-300. Although natural, Bitter Orange Extract has been banned in countries across the world due to its harmful side effects. Some of them include;

  • Heart Palptations
  • Excessive Sweating
  • Insomnia
  • High Blood Pressure

Due to its aggressive nature, we highly suggest staying away from Bitter Orange Extract as far as possible.


Yohimbe Extract is another dangerous ingredient in JetFuel T-300 by GAT. Just like Bitter Orange Peel, it’s disguised as an all-natural ingredient.

However, once you look at the side effects it causes to people, you realize just how dangerous it is. It’s very aggressive on your heart, which is why it’s been banned in numerous countries.

Definitely an ingredient to run away from!


People have commonly believed that Ashwagandha can raise testosterone levels. However, no study has shown this to be the case.

Ashwagandha has other uses, though. For starters, it boosts your immune system, lowers stress, and improves endurance in workouts. This makes it a great ingredient for athletes and anyone who wants to combat fatigue and stress.

Magnesium Aspartate

Magnesium Aspartate will help you with your cardiovascular and nerve health if you’re deficient in it, but don’t expect much in terms of boosting testosterone.

MCT Powder

Medium-Chain triglycerides are believed to help suppress appetite, which can be great in a fat burner.

But since JetFuel T-300 by GAT is mainly a T-booster, it’s a pointless ingredient.


Bioperine doesn’t have any benefits per se, but it does improve the effects of other nutrients in GAT JetFuel T-300.

It does this by increasing these ingredients’ bioavailability, improving their absorption in your body.

Explotab Sodium Starch Glycolate

There aren’t many studies behind Explotab Sodium Starch Glycolate. It’s thought to expand in your stomach when you ingest it, making it a good appetite suppressant.

But since there’s not much evidence behind this, we can’t say how effective this ingredient will really be.

A better alternative to this ingredient would be glucomannan, which has been proven to work and is safe.

What Others Say

JetFuel T-300 by GAT Testosterone Booster and Fat Burner Review

“I am a bikini competitor and did not sleep AT ALL due to the energy boost these pills gave me. It added stress and did not make me as lean as other products.” – Amazon Customer

“I took the product for 7 days as directed prior to a beach vacation. I work out regularly and eat healthily. I’ve only noticed a very small difference. I wasn’t expecting miracles but thought I would notice a bit more muscle definition.” – Amazon Customer

“It really didn’t do anything for me besides have a pain in my kidneys after taking them every day for 2 weeks. I suggest you drink ALOT of water.” – TC (Amazon Customer)

Side Effects

As we’ve already mentioned, Yohimbe Extract and Bitter Orange Peel are full of negative side effects.

Some of the more concerning ones include;

  • Irregular heartbeats
  • Raised blood pressure
  • Uncontrollable sweating
  • Breathing problems

There’s also a concern with Tribulus Terrestris, which has been linked to prostate aggravation in men. So in a nutshell, JetFuel T-300 by GAT contains some really dangerous ingredients.

Conclusion to JetFuel T-300 by GAT

Unfortunately, JetFuel T-300 by GAT is a product with too many downsides. While it has some good ingredients, like cayenne pepper, magnesium, and even ashwagandha. It also comes with a lot of dangerous ingredients, like Tribulus and Bitter Orange Peel.

Many of the beneficial ingredients are also underdosed, or come in poor forms. This all results in a below-average product with more shortcomings than benefits.
