Our TestoFuel review aims to find out if this popular Testosterone Booster actually can help boost your hormone levels. 

Testosterone is the key male sex hormone, playing a major role in muscle growth, fat loss and optimal health.

As you get older, your testosterone levels decrease, resulting in a lower libido, loss of muscle, increased abdominal fat, lack of focus and numerous other issues.

Testosterone Boosters are natural supplements that can increase your testosterone levels without the need to use gels or syringes. They work by directly affecting Testosterone (or related hormones), but they can also be effective by preventing Testosterone from being converted into Estrogen.

TestoFuel is definitely one of the most popular Testosterone Boosters we’ve come across and numerous online reviews & testimonials back up the effectiveness of the supplement.

In this TestoFuel review we’ll take a closer look at the ingredients, expected benefits and cost to see if it really can live up to the hype.

Benefits of TestoFuel

Given the quality of ingredients in TestoFuel, here are the benefits you could expect to see/feel:

  • Build muscle
  • Increased libido
  • Lower body fat
  • Enhanced mood
  • Better sexual performance

Build Muscle

Scientists suggest that testosterone increases muscle mass by elevating muscle protein synthesis. This means that by boosting testosterone to their optimal levels, Testofuel can help enhanced your muscle building capabilities.

Enhanced Mood

Men with lower Testosterone levels are often lacking in confidence, likely due to other effects of low Testosterone like reduced muscle mass, increase body fat etc.

An increase in Testosterone can help enhance your physique and sex life, which should result in an improved mood.

Lower Body Fat

Increase Testosterone levels can positively impact your body composition.

Firstly, by prompting an increase in lean mass, users should experience an elevated metabolic rate at rest. This is because muscle contributes more toward your TDEE than body fat at approximately 20% compared to 5%.

What’s more, testosterone should help to regulate body fat. Several studies have linked low testosterone levels with obesity, which men become more vulnerable to as they age.

Increased Libido

As we touched on earlier, Testosterone is they key hormone when it comes to your libido and sexual performance. That’s because areas of the brain are linked to sexual desire. When triggered by the male sex hormone, receptors in the brain increase the desire to have sex as well as encouraging the penis to produce an erection.

When Testosterone levels are low, it can impact your desire to have sex. This means it can also affect the ability to achieve and/or maintain a satisfying erection as well as there being risk of infertility.

    Is TestoFuel safe?

    TestoFuel features a completely natural formula. Each of its suggested serving sizes have been created in accordance with scientific guidelines, which means they should not pose an unnecessary risk or dangerous side effects.

    TestoFuel is also free from proprietary blends, meaning there are no hidden fillers/ingredients and you know exactly how much of each ingredient you’re getting.

    TestoFuel Review of ingredients

    TestoFuel contains nine natural ingredients. Having taken a closer look at the ingredients, we believe that each ingredient and their dosage are based on scientific research. The are no superfluous ingredients in this mix.

    Testosterone Boosters are for men of all ages, although generally 30+ years old and TestoFuel definitely seems to be aimed at the younger men in that bracket. Whilst Testosterone Boosters for older men may be heavily focused on Testosterone to help improve libido & sexual performance, TestoFuel also has one eye on improving physique.

    To see how TestoFuel does this, lets take a look at the key components:

    Vitamin D3

    Vitamin D3 is fundamental for optimizing testosterone. Our body also naturally creates it when we come into contact with sunlight.

    What TestoFuel have done well is include a generous 5000 IU of D3 in one serving. According to studies, 3,332 IU of this ingredient is needed to significantly raise testosterone, so they’ve definitely making sure you’re not lacking in D3.

    Vitamin K2

    Traditionally found in red meat, egg yolks, and liver, K2 jumpstarts hormone release. Also known as ‘menaquinone’, this vitamin works hand in hand with D3 to increase testosterone production.

    The addition of K2 is definitely a bonus, as one study showed 5 weeks of supplementation led to a 70% increase in circulating testosterone.

    Vitamin B6

    B vitamins are widely used for general wellbeing, keeping our eyes, hair, skin, and liver healthy. Plus, B6 especially helps the blood transport oxygen, playing a big part in energy upkeep.

    B6 also reduces estrogen build up in men, allowing testosterone to work unrestricted.

    Magnesium

    Without Magnesium our bodies wouldn’t function, that’s why you’ll see it included in numerous supplements. It’s involved in over 600 bodily reactions including protein formation, energy creation, muscle movements and regulation of the central nervous system.

    However, the inclusion of magnesium also reinforces TestoFuel’s testosterone-boosting claims. Studies have shown it has a positive influence on anabolic hormonal status in men.

    Zinc

    Like magnesium, zinc is considered to be an essential nutrient. Your body needs it for many functions including immune function, growth and development, protein synthesis and gene expression.

    As a result, zinc deficiencies cause androgen receptors to become inefficient. This makes healthy zinc levels vital for optimized hormone balance, especially testosterone.

    D-Aspartic Acid (DAA)

    DAA is known to boost parts of the brain that regulate luteinizing hormone release. Once triggered, luteinizing hormone travels from the pituitary gland and tells the testes to produce testosterone.

    One study showed 90 days of DAA supplementation saw an average increase in testosterone levels of 30-40%. Not only that, but further research into the amino acid indicates it can be used to treat infertile men, as well as athletes looking to increase strength and muscle mass. 

     

    How to take TestoFuel

    The creators of TestoFuel have advised that you take 4 capsules throughout the day to achieve the best results.

    We recommend taking TestoFuel using this pattern:

    • First capsule with breakfast
    • Second capsule at lunch
    • Third capsule between lunch and dinner with a snack
    • Fourth capsule in the evening with either dinner or a snack 

    We would advise following the creator’s guidelines and the pattern above should help your body absorb the nutrients throughout the day. We wouldn’t advise straying from the guidelines as you may see reduce effects or increased risk of side effects.

    How much TestoFuel cost?

    A complete container of TestoFuel contains 120 capsules, which amounts to 30 days’ worth – based on taking 4 capsules per day.

    An individual bottle of TestoFuel will set you back $65/£39 but as it can take some time for supplements to have an effect on your body, we’d advise going for the 2 bottles or 3 bottles option – if you do opt for the 3 bottles, you’ll get a 4th bottle for free and you’ll qualify for the money back guarantee.

    Conclusion

    One thing we’ll always put a focus on in these reviews is ingredients, and once again Roar Ambition have been completely transparent and have listed all their ingredients without a proprietary blend – a big thumbs up from us.

    As a result of seeing exactly what you’re putting in your body (and it being all natural), this is a safe Testosterone Booster to take.

    At $65, TestoFuel is more expensive than some of its competitors but you get what you pay for. Of course, you can opt for the cheaper options that are out there, but you won’t get the same results that you’d see with TestoFuel – therefore we think the extra cost is worth taking the hit on.

    If you’re looking for a Testosterone Booster that not only boosts your mood/libido but can help you improve your physique then we wouldn’t put you off purchasing this supplement.
