Battle Fuel XT is a natural test booster from Musclepharm. It is designed to appeal to bodybuilders, offering a natural alternative, so they don’t have to resort to more dangerous performance enhancement.

Battle Fuel claims to use a four stage approach to boost the amount of testosterone in our system, giving us all the benefits that come with higher levels of test:

  • Increased muscle mass and strength
  • Better stamina
  • Higher energy and increased sex drive

This means 4 proprietary blends. Ordinarily we don’t like to see this ( ingredients should be named and dosed individually) but there’s enough here to catch the eye. Let’s get in to the all-important formula.

How Does Battle Fuel XT Work?

Before we hit the proprietary blends, there are a few ingredients given their own unique amounts, so let’s size them up first.

Vitamin D – This is a great choice. vitamin D levels have repeatedly been linked to testosterone. It is drawn mainly from exposure to sunlight, which is why our T drops in the winter. However, vitamin D only helps do this at dosages of around 3,300IUs (the Vitamin D Council recently recommended a daily intake of 5000IUs.) So the 600IUs present here simply isn’t going to get it done.

Magnesium – A lot of guys don’t appreciate that the overall T in their system doesn’t automatically equal what we have free to use. Up to 60% of your horomone can be tied up by Sex Hormone Binding Globulin, lying dormant in the body. Magnesium is one of the best natural ways to release this T, allowing more of it to fuel our physical performance. 225mg is a well-judged amount to  do this successfully.

Zinc – Yet another good choice here. Zinc is vital for the creation of luteinizing hormone which ihas a hand in how much testosterone is produced in our balls. This mineral is difficult to get enough of from diet, so supplementing is a good idea. Sadly with a small 4mg per serving, Battle Fuel isn’t nearly as strong in the zinc department as other brands. We would be looking for about 30mg ideally.

Now we come to the first ‘stage’ (blend) known as the Testosterone Amplifier. With a few notable exceptions, we don’t know the volume of each ingredient but the combined amount of all 4 stages is 6226mg

D-Aspartic Acid – Strong start. D-AA works on the central region of the brain promoting the release of hormones important for T, like luteinizing hormone, growth hormone and follicle stimulating hormone. Battle Fuel ignores the proprietary blends rules for D-AA and gives it its own dose. It’s easy to see why with a whopping 3000mg included. This is just about the biggest amount we’ve seen in a booster.

Mucuna Pruriens – Another solid pick. Mucuna pruriens have been shown to increase levels of our free testosterone and are a rich source of the amino acid L-Dopa (billed here as 50%). L-Dopa (also known as levodopa) is a widely known booster of T and Human Growth Hormone. Velvet bean as it’s also known is great for vutting cortisol too. Cortisol is a stress hormone as it produced if we are under pressure, blocking T. Thanks to it being part of a proprietary blend, there’s no way of telling how much is in Battle Fuel.

Asteracantha Longifolla Aquatic Extract – Probably the weakest link in this blend, this extract of a plant used in traditional Indian medicine hasn’t shown a whole lot of promise, but has displayed some ability to positively affect sex drive. Which, let’s face it, is always welcome and better than nothing.

Moving on to the second stage now, we come to the Testosterone Activator blend.

Acetyl-L-Carnitine – This is another ingredient that slightly misses the mark. Acetyl-L-Carnitine doesn’t help T but is great for fat loss because it aids transportation of long chain fatty acids to be burnt off for fuel. This also gives you more energy to play with. So Acetyl-L-Carnitine may help you build muscle through extra time in the gym. But that’s us being generous.

Anacyclus Pyrethrum – Anacyclus Pyrethrum has been shown to up levels of serum T and luteinizing hormone in rats. We’re still waiting for more human studies. However this ingredient is a pretty potent libido booster, with the effects lasting even several weeks after you’ve stpped taking it..

Curculigo Orchioides – Again, this ingredient’s inclusion in boosters stems mainly from research conducted on lab rats and even those aren’t terribly convincing. About as far as anyone is willing to go is to say that this component promotes ‘testosterone-like effects’ doubtless in reference to its more established sex drive enhancing qualities.

Level 3 is the Testosterone Muscle Growth Complex.

Suma Extract – Suma feels like a good choice because it has various elements which act as the building blocks for T synthesis. These include B vitamins, vitamin K2, zinc, magnesium, ecdysteroids, saponins, and steroidal glycosides. It also helps nitric oxide levels in the body, improving blood flow and increasing energy.

Maca 4:1 – Maca can help levels of nitric oxide in the body, stimulating blood flow and aiding erections for sufferers of erectile dysfunction.

Propionyl Carnitine – Another ingredient with all its standout qualities focused on sex drive and erection strength. No direct boost to T, so very much secondary benefits.

The last stage is the Anti-Aromatase and Estrogen Suppression Matrix. Estrogen is the female hormone which we all have amounts of in our system. It exists in direct competition with testosterone, meaning that when one is high the other is low.

DIM – Found in broccoli and kale and other green leafy vegetables, Di-Indoly Methane as it is technically known has shown some real promise in clinical trials as far as the effective suppression of estrogen. There’s not quite enough evidence out there just yet for us to fully endorse as a nailed on anti-aromatase option, but it looks to be headed in the right direction.

Indole-3 Carbinol – Indole-3 Carbinol is converted to DIM when it is digested so see above.

How Do I Take It?

Users should take 2 servings of 4 capsules a day. That’s 8 capsules in total, which is a lot. Even customers who really rate Battle Fuel XT complained this was high in reviews.

As few as 4 capsules over the course of a day can be effective. Battle Fuel also recommends you take the this for 8 weeks then rest for 4 or 5 days.

Alongside the high volume of capsules that need to be consumed, this could be quite daunting for newcomers to boosters. We also have our doubts about instructions to ‘cycle’ a natural test booster. These types of recommendation tend to eminate from the marketing department rather than the lab.

Side Effects

We wouldn’t normally link this formula with side effects. However they do warn you to stop taking this product if you start having cramps and diarrhoea. Which kind of implies it’s not out of the question.

It (should) go without saying that if you have any reactions like this you should stop taking it. You should also consult your doctor first if on any prescription.

Where Can I Get Battle Fuel XT

Customers can find Battle Fuel XT from most online retailers. Selling around the mid to high $30 mark in the U.S and £20 region in the U.K.


Battle Fuel XT

Ingredients (8/10) – There are some really good T. D-Aspartic Acid at 3000mg is great. Battle Fuel also deserves credit for including an anti-estrogen profile. Though a few ingredients which still have a question mark over them and a couple are under dosed. Somewhere around 2000mg of D-AA would’ve probably have done, freeing up space to strengthen the vitamin D and zinc. However, nothing here is useless and choices which aren’t directly boosting your T usually have other uses, such as helping  libido.

Price (5/10) – The price we feel could be better. It’s not the most expensive booster on the market, and most of the formula is solid, but there are only 20 servings in a pack. Battle Fuel recommend it is taken every day for two months, that’s 60 days right there which means 3 purchases. At upwards of $30 that’s going to add up quickly. Would be lower ideally.

Testimonials (6/10) – There aren’t testimonials on the Musclepharm website so mainly you have to rely on reviews left by customers. We can understand why they’d feel confident doing this, the feedback is overwhelmingly positive, but these reviews often don’t go into the level of detail you’d want from a specific testimonials section of a website.

Trustworthiness (9/10) – No problems here. Musclepharm’s products are produced in the U.S and so subject to all the quality controls which come with that. We couldn’t find any big customer service scandals either. The only reason we haven’t awarded full marks is the proprietary blends confusing dosing.

Company 10/10 – Musclepharm is an well-established and respected company whose founders include former American Football player Brad Pyatt. They are very involved with the mixed martial arts scene and have a stable of athletes carrying the banner for them. Among them, Tiger Woods. Also the face (and the everything else) of bodybuilding, Arnold Schwarzenegger, who launched his own line of supplements with them.


This is a really good product. And as we hate proprietary blends it takes a lot for us to say that.

Some stand out T boosters and good estrogen blockers from a professional and trustworthy company.

However for the sort of money being asked we feel there are other options out there whose ingredient profile is a little more even quality wise and don’t require 8 capsules a day or cycling.
