TestoFuel Review – My Personal Results As A Nutrition Coach

by Joe Costello, CNC | Testosterone Boosters

My TestoFuel testosterone booster pills outside of the bottleThis TestoFuel review looks at one of the best testosterone boosting supplements in the industry. TestoFuel is a testosterone-boosting muscle builder that is made of all-natural ingredients. This product is manufactured by Peak Health Labs, Inc. and is packaged in 120 capsule bottles – a one-month supply.

TestoFuel enhances many of the male body’s working mechanisms, including the metabolism, protein synthesis and testosterone production as well as increasing the breakdown of fat, improving the mood, and increasing energy.

I am a Certified Nutrition Coach (CNC), and I have to say, my results were pretty great. I was really impressed with the benefits it produced for me in the gym specifically. I was able to lift more weight, my endurance was better, and I gained a lot of muscle. My personal experience with it did not give me a lot of results in terms of sex drive, but this stuff is great if your main goal is to build muscle.

See how TestoFuel ranks on our list of the top 10 testosterone boosters.

My Personal TestoFuel review: Is TestoFuel any good?

TestoFuel is undoubtedly one of the best testosterone supplements on the market. There are very few T Boosters that I would classify as elite, but this is one of them. I tend to be very picky with test boosters – they need the right ingredients, high potency, large dosages, etc.

TestoFuel is one of a select few that checks all of my boxes. Plus, I had an excellent personal experience with this test booster. I’ve tried a lot of them, and as a NASM certified nutrition coach, I can say this is easily one of the best I’ve ever had. I’d strongly recommend it!

Generally, with testosterone supplements, I expect to experience benefits in the gym or in the bedroom. With TestoFuel, I would say the vast majority of the results I got were in the gym. My strength was improved, I could lift more, I could do more reps, and I was just having better workouts the entire time I was taking it. It didn’t do a lot for me in the bedroom, but that’s not what I was looking for, so it’s all good.

If you’re looking for a testosterone booster that produces good results in the gym, I can confidently say after taking TestoFuel for 30 days that this is a solid choice. HOWEVER, the reason it is not my top ranked T booster is because it didn’t do anything for me in the bedroom. TestoGen is my top ranked option because it is the best personal results I have ever gotten from a test booster in BOTH the gym AND the bedroom. I like both of these supplements, but I’d give TestoGen the edge.

What does TestoFuel do?

Me holding my bottle of TestoFuelWhat does TestoFuel do for you? The extremely potent combination of natural herbs and powerful amino acids is designed to promote increased production of free testosterone in your body.

As a result, men can expect to experience a wide array of benefits related to athletic and sexual performance…we’ll talk more in depth about this later. My personal favorite benefit of TestoFuel is the way it made me feel in the gym. I took TestoFuel almost as a pre workout supplement and it did a lot for me in terms of energy, stamina, endurance, and ultimately muscle growth.

Natural testosterone boosters are supplements that are designed to support and boost testosterone levels in the body. While they may have some influence on testosterone production, it’s important to note that their effects can vary among individuals, and they are not a substitute for medical treatment (or testosterone replacement therapy) in cases of diagnosed testosterone deficiency, low testosterone, or erectile dysfunction. If you have been officially diagnosed with something like Low Testosterone (also referred to as Low T), always follow the instructions of your primary care physician.

Here are ways in which natural testosterone boosters may help boost testosterone levels and potentially stimulate muscle growth:

Nutrient Support

  • Zinc: A key mineral involved in testosterone synthesis. Natural testosterone boosters often contain zinc to support healthy testosterone levels. It is also believed to positively effect your LH (luteinizing hormone) levels. Luteinizing hormone is an important reproductive hormone produced in the pituitary gland, which means having optimal luteinizing hormone levels can enhance your reproductive health. Many people naturally have a zinc deficiency without knowing it. For these people, zinc supplementation can be especially helpful.
  • Vitamin D: Vitamin D is a fat soluble vitamin that is essential for testosterone production. Some individuals may have Vitamin D deficiencies, and Vitamin D supplementation is included in many testosterone boosters. In Testofuel specifically, Vitamin D is especially effective because it is combined with the naturally occurring amino acid D Aspartic Acid. I have found in my personal experience testing TestoFuel that the combination of DAA and vitamin D supplementation was able to effectively boost testosterone production. Just remember this phrase: Vitamin D is the key!
  • Vitamin B6: Vitamin B6 can produce a wide array of health benefits and has been known to work very well with Vitamin D. Combining Vitamin D and Vitamin B6 (like companies do with multivitamin supplements) can help your body more effectively build muscle. It may sound basic, but don’t sleep on vitamins! If you’re serious about getting muscle gains, you need sufficient amounts of Vitamin B6 and Vitamin D.
  • Vitamin K2: Vitamin K2 is crucial for bone health and skin health. If you are seeking muscle development, your bones need to be able to support that muscle development, and proper Vitamin K2 levels is an important aspect of that.

Herbal & Natural Ingredients

There are many natural ingredients and herbs within Testofuel that can help increase testosterone production. We will get into the full list of natural ingredients later, but here are some of the most important ones…

  • Tribulus Terrestris: Claimed to enhance testosterone production.
  • Ashwagandha: Associated with improved fertility, increased testosterone levels, and elevated energy levels.
  • Fenugreek: Studies have shown that it may be effective at boosting testosterone levels when combined with resistance training.

DHEA Supplementation

Dehydroepiandrosterone (DHEA) is a hormone that serves as a precursor to testosterone and therefore may boost testosterone levels. Some natural testosterone boosters include DHEA to potentially raise testosterone levels. Testofuel does not contain DHEA, but as a nutrition coach, I personally don’t see this ingredient as a necessity if your goal is just to increase testosterone levels and boost muscle growth.

Lifestyle Support

Natural testosterone boosters often emphasize healthy lifestyle habits known to support testosterone production. This may include recommendations for regular exercise, stress management, and adequate sleep. All of these things can help contribute to natural testosterone production, more efficient muscle growth, and higher energy levels in general.

Anti-Estrogenic Effects

DIM (Diindolylmethane): A compound found in cruciferous vegetables, DIM may have anti-estrogenic effects, helping to balance estrogen and testosterone levels. All of the best natural testosterone boosters contain estrogen blockers. Estrogen blockers are the key to ensuring that testosterone levels remain high while estrogen levels also stay low simultaneously.

Increased Protein Synthesis

Elevated testosterone levels can support protein synthesis, which is crucial for muscle growth and repair. This process is essentially how lean muscle mass is created, so if you can take a supplement that aids with protein synthesis, you could naturally increase your muscle mass.

Reduced Muscle Protein Breakdown

Testosterone may help inhibit muscle protein breakdown, contributing to a more favorable environment for muscle growth. If you want to build lean muscle mass, it’s important to make sure your muscles are well fed with protein. Protein is essential for muscle growth, so if you can reduce the rate at which it is broken down, you are effectively promoting muscle growth within your body.

TestoFuel ingredients list

Here are the primary ingredients in TestoFuel:

D-Aspartic Acid

Testofuel ingredients and supplement factsD-Aspartic Acid is the most important core ingredient of any and all testosterone boosting supplements in my opinion. Clinical studies have shown it has tremendous potential with regard to short term testosterone increase. This essential amino acid is an absolute game changer, and we love that TestoFuel provides such a large dosage.


Ginseng is an ancient asian herb that has been used for ages to boost libido and enhance sexual health in men. As one of the most tried and true libido boosters available, it’s a great addition to the TestoFuel formula. It’s also believed to help increase nitric oxide levels, which can produce an array of additional benefits.


Fenugreek is a natural herb that has been extensively researched with regard to its testosterone enhancing and sexual health benefits. Studies have shown that men who regularly supplement with Fenugreek report significant sexual improvements over relatively short periods of time.

Oyster Extract

Oyster Extract is considered an aphrodisiac because some clinical trials have shown that it may potentially be able to help your body produce testosterone. If oyster extract truly can trigger natural testosterone production within the body as many researchers believe, it would be a game changing ingredient. From the clinical studies on oyster extract I have read, researchers actually seem to believe that oyster extract helps produce testosterone because it naturally contains a high amount of the next ingredient we are going to talk about: Zinc.


Zinc is perhaps the single most popular test boosting ingredient on the market. This trace mineral can be found in almost every testosterone supplement we have reviewed on our site, and for good reason. There is plenty of evidence that suggests it may positively effect libido while simultaneously boosting testosterone production. The clinical studies are certainly very promising.


Magnesium is an essential mineral that evidence based clinical studies have shown can produce a long list of benefits related to bone health, joint health, and even muscle health. Magnesium supplementation is key if you are seeking proper muscle development. Increased muscle mass means your body is going to need more magnesium, and supplementing with it is a great way to give yourself a boost.

TestoFuel pros and cons

Here are the benefits and side effects of TestoFuel testosterone booster.

TestoFuel benefits

The wide array of commonly reported TestoFuel health benefits include better sex drive, improved athletic performance, increased muscle mass, and higher energy levels. The extremely potent formula of this natural testosterone booster (and specifically the large dosage of D Aspartic Acid in TestoFuel) is what allows it to boost testosterone levels effectively. Without the dosages being high enough, you simply can’t expect to get h health benefits, but that is not the case with TestoFuel, so no worries there.

TestoFuel’s muscle building ability comes from its potential to boost testosterone production. High levels of testosterone increase the digestion and absorption of food (inclusive of proteins), which, in turn, leads to the growth of muscle fibers. Combined with a diet that includes a lot of lean protein, TestoFuel could be a dramatic muscle-building tool.

Testosterone is the hormone that is most attributed to masculinity in men, although women have low levels of this hormone. Adequate levels of testosterone increase and maintain a high sex drive in men. High sex drive enables men to achieve and maintain strong erections during intercourse and significantly contributes to a higher quality of life. Here is a brief list of the benefits of the increased testosterone production Testofuel can potentially provide…

  • Increase muscle gains and enhance muscle development
  • Reduce body fat if combined with regular exercise and a healthy diet
  • Provide your body with more energy (and more energy leads to better workouts)
  • Enhanced muscle recovery
  • More free testosterone
  • May help relieve some symptoms of Low Testosterone

TestoFuel side effects

If you examine the supplement facts panel (SFP), you will see that all of the ingredients are 100% natural. Therefore, it is highly unlikely that the user would experience any significant or dramatic side effects. The whole point of a completely natural testosterone booster is to avoid side effects…

With that being said, some people can have a strange reaction to supplements that boost testosterone production. Some of the side effects TestoFuel could cause include headaches, upset stomach, and anxiety. Again, these aren’t very likely, but they have been reported. In my opinion, it’s possible that an effective testosterone boosting supplement like TestoFuel could cause some anxiety in the beginning just because of how powerful it is. Also, if you have any allergic reactions to the ingredients, that’s a whole different story, which is why you should always consult your doctor before starting a new supplement.

TestoFuel complaints & praise (TestoFuel reviews from real users)

TestoFuel does not currently have a lot of user reviews available on Amazon or any other reliable website, but almost every single third party review is positive. While we couldn’t find a lot of TestoFuel reviews submitted by users, luckily for you, I have personally tried this stuff…so, I’ll give you my review.

As a guy who is super into fitness and bodybuilding, I personally test many of the supplements I review. Testosterone boosters are one of my favorite types of supplements to experiment with. I’ve tried quite a few, and I have to say, TestoFuel was one of my all-time favorites.

TestoFuel contains a huge dosage of D-Aspartic Acid (DAA) at 2,300 MG per serving, and DAA is the primary active testosterone boosting ingredient when it comes to short term results. In other words, if you can feel the effects right away after taking a serving, it’s likely a result of the DAA.

Suffice it to say, this giant dosage of DAA certainly did not disappoint. TestoFuel kicks in fast and hard, and the short term results were amazing. I only bought one bottle and took it for 30 days, but I wish I bought more so I could experience and talk about the longer term results.

In the short term I had great performance enhancement in the gym, amazing pumps, great energy, and better endurance. The effects were lasting as well since the DAA dosage is so large, and the rest of the formula is complementary to it. In other words, I did not feel as if I was building up a tolerance.

I can definitely see myself buying TestoFuel again in the future, and it is one of my top recommended test boosters without a doubt. In terms of other testosterone boosters I have tried, the only other one I liked better than TestoFuel was called Testogen. I had my T levels tested when I took each one, and Testogen produced more testosterone for me than TestoFuel did. I still had more testosterone in my body after taking TestoFuel, but the change in my levels was not as significant as it was with Testogen. I also had more significant muscle gain when I used Testogen, which was my whole goal to begin with.

Is TestoFuel worth it? My TestoFuel review conclusion

All things considered, we can say without hesitation that this is one of the best test supplements available. The ingredient panel is very impressive, the dosages are large, the overall potency is super high, and our own staff has personally had great results with it including myself. If you are looking to boost your free testosterone levels without having to to testosterone therapy, this is a good option in my personal option as a Nutrition Coach.

TestoFuel is one of our top recommended T Boosters, and it’s likely going to stay in our top five for a long time unless they change the formula. There are very few competing supplements that come even close to this one. With that being said, our top ranked testosterone booster is pretty significantly more potent than this one, and I did find in my personal experience that Testogen (the top ranked best testosterone booster) did more effectively boost my free testosterone levels in a more significant way than TestoFuel.

I had my free testosterone levels (also known as serum testosterone levels) tested before and after I took each one of these supplements, so I can pretty definitively say that Testogen is the more effective testosterone booster (at least for me personally). If you enjoyed my TestoFuel review, you’re going to love my Testogen review! You can read that one here: Testogen Review



Is TestoFuel safe?

We believe TestoFuel is safe for two reasons…1) the formuls is 100% natural, and 2) our own staff tested it and had great results with it. Generally, natural testosterone boosters can be considered safe as long as they don’t contain any sketchy ingredients. There’s nothing in this formula that I find troubling, and there are a bunch of great ingredients that are believed to promote healthy testosterone levels, so I don’t see anything to worry about here. However, I am not a doctor and you should always consult your primary care physician with this question, especially if you have been officially diagnosed with a testosterone deficiency or a zinc deficiency.

How long does TestoFuel take to kick in?

Due to the enormous dosage of D-Aspartic Acid, it should kick in pretty soon after your first serving. It appears most people report experiencing results within a couple days of starting it, and results tend to only improve over longer periods of use. That was the case for me personally as well.

How should I take TestoFuel?

TestoFuel should be taken exactly as per the instructions on the bottle. Make sure to take your dosage every day. Don’t skip dosages! Also, try taking it prior to your daily workout. I found that it enhanced my exercise performance when I took Testofuel before going to the gym, so I’d recommend trying that method out.

What is the daily dosage?

The manufacturer recommends taking 4 capsules daily. When it comes to supplements related to sport and health science in general, it’s very important to adhere to the directions on the label. That’s what I did, and I had pretty great results. With dietary supplements in general, you should really never deviate from what the label tells you to do. You don’t want to risk taking too much and getting side effects as a result.
