What is Testofuel?

Testofuel is an over-the-counter testosterone-boosting supplement designed especially for males. It is marketed toward bodybuilders or men who are working on building lean muscle and shedding fat (in other words, cutting a great physique).

Instead of adding testosterone to the ingredients, Testofuel boosts natural testosterone release. By increasing natural testosterone levels and reducing estrogen, Testofuel aids muscle repair and growth while improving focus, mood, and libido.

About the brand

Testofuel is based in Leeds, UK, and is a sub-brand of the parent company Roar Ambition (who also makes Prime Male and Instant Knockout).

Roar Ambition stands for secure payments, no recurrent billing, and decent refund policies. We’re confident in the integrity and safety of the brand so far.

How Does Testofuel Work?

testofuel t-booster

Testofuel works by triggering the hormones and processes in the body that are responsible for testosterone production. Note that Testogen doesn’t include any testosterone.

In short, more testosterone means better muscle building, improved fat distribution (away from the breast and stomach area), a stronger libido, and a brighter mood.

Here’s how the key ingredients work:

  • D-Aspartic Acid and ginseng boost the luteinizing hormone, the hormone that triggers the testes to release testosterone
  • More testosterone means greater muscle gains and a leaner physique (when combined with working out and a clean diet)
  • Vitamin B6 helps to boost energy levels, increases testosterone, and reduces estrogen. This helps with effective workouts and helps to reduce and prevent fat around the torso
  • Magnesium supports restful sleep and muscle repair, helping your muscles fibers to repair bigger and stronger than before
  • Zinc, ginseng, and oyster extract support healthy erections and sexual health

Testofuel Real User Reviews

testofuel before after

The Testofuel website is filled with testimonials in video and image form. The before-and-after pictures are a testament to the effectiveness of Testofuel when given the time to work. You can see drastically different physiques showing more muscle and less fat around the middle.

The guys who gave Testofuel a fair shot (at least 2 months) found these results:

  • Stronger muscles and better lifting results in the gym
  • Reduced fat and more visible muscle tone
  • More confidence
  • Increased sex drive
  • No side effects

For example:

“I’ve had more than a few people at the gym ask if I was taking steroids; I personally wouldn’t take them, but feel like TestoFuel is the next best thing and without the risk of harmful side effects. I’ve also noticed an increase in my sex drive and a overall sense of well being”.

This customer found that their muscle tone grew and improved slowly but surely, with the added bonuses of a stronger libido and better mood.

“I’d be lying to you by saying you will put on 10kg in a couple of weeks and double your personal best on bench press because of one simple reason: they are not steroids. With that being said, they are the best natural supplements I have tried out so far, I went from 88kg to 93.5kg in 4 months… packing on muscle is a slow process (a bit faster at the very beginning though)…along with a good diet and regular training, TestoFuel made me gain 5kg in only 4 months! The increase in testosterone improved my libido and my mood”.

It’s clear that if you want to go from your current physique to a ripped, shredded muscle machine it takes more than a supplement. You need to follow a regular workout plan and eat a clean diet.

However, Testofuel can make sure that your efforts pay off in a visible and significant way, far more so than if you went without.

If you don’t work out and watch your diet, you could still benefit from better overall strength and endurance, better sex drive, and a more stable and bright mood.

How Do I Take Testofuel?

Take four capsules each day, with water.

There’s no need to cycle Testofuel (which is when you take breaks after extended usage) according to the official site.

Side Effects: Is Testofuel Safe For Everyone?

Testofuel uses all-natural ingredients that are considered safe for most people, therefore, the risk of side-effects is very low.

However, even the most gentle supplements can cause side-effects if you are allergic or are taking particular medications. It may also depend on age, weight, and other factors.

For example, vitamin D3 is considered generally safe, but high doses might cause side-effects such as nausea. In this respect, it’s crucial to follow the instructions and refrain from exceeding the recommended dosage.

The bottom line is that Testofuel is considered safe and will be very unlikely to cause side-effects. However, check with your doctor if you are:

  • Under 18

  • Are taking regular medications

We think Testofuel is worth giving a go, especially if you want to feel stronger, build more muscle, and get that youthful “pep” back.
