- Very good serving sizes of key ingredients
- D-Aspartic Acid stacked with Red Ginseng should be a potent combination
- Side effect risks appear minimal
- 5,000IU of Vitamin D is an industry benchmark
- Fenugreek improves libido but not test!
- Could use an aromatase inhibitor
This is an excellent natural testosterone booster. There’s a reason that TestoFuel has remained one of the most popular and talked about bodybuilding supplements on the market today – it really works! The formula is comprised entirely of effective, proven natural ingredients. Together, they tackle multiple different problems – vitamin and mineral deficiencies, low LH production, and more. The end result is a stack capable of reliably and quickly raising your free serum testosterone levels, which means faster muscle gains, faster recovery, and increased strength. The addition of Fenugreek and Oyster Extract means that your hard training wont put a dent in your bedroom performance – a lovely bonus!
Our TestoFuel Review
TestoFuel is without doubt one of the most widely-used testosterone boosters in the world. It was launched a few years ago, but it has remained extremely popular since the first day it hit the shelves. This is enough to set it apart from most other testosterone boosters out there, the majority of which gain serious traction in their first few months and then swiftly disappear when people realize that they’re bogus. TestoFuel has definitely stood the test of time!
So why has it remained so popular among weightlifters and bodybuilders?
What does it claim to offer and how does it work?
TestoFuel is principally designed for use by young bodybuilders, fighters, physique competitors, and athletes of just about every kind.
According to the website, users of TestoFuel can expect the following core benefits within just a few weeks of starting to use the product:
- Enhanced muscle growth
- Faster recovery after training
- Rapid increase in strength
- Significantly increased libido
- Greater energy levels
- Improved mood
Obviously these benefits all result from one central promise of TestoFuel – a real increase in free serum testosterone levels.
If TestoFuel can really bring about a meaningful rise in test levels, then all of these benefits will follow (and many more besides).
So, does TestoFuel really work?
How does it compare to other products on the market today making the same claims?
Find out by reading our full TestoFuel review below. We’ll put the formula under our microscopes and see whether it really stands a chance of doing any of the things it says it can. We’ll talk about the side effects and health risks too. Have you used TestoFuel? How did you find it? Let us know in the comments!
TestoFuel Formula – Does It Deliver?
Let’s take a look under the hood and see if TestoFuel backs up all its big talk:
Right away, we can tell that this is a good quality testosterone booster.
We see a very good range of top quality ingredients.
There’s a good diversity of ingredients here; TestoFuel clearly targets several different pathways through which you can elevate serum testosterone levels. This is ideal, because few men can accurately identify the main cause of low testosterone – it’s always best to just hit them all at once!
The quality of the ingredients is also second to none.
There’s no waste here either. No fillers, no over-hyped garbage, and nothing dangerous. Every ingredient has a place, and they all have a real effect on testosterone levels, sleep quality, and libido.
There are some problems, however. We think there are some well-proven ingredients that could be included to make this supplement much better. For example, there’s no natural aromatase inhibitor. We also think the doses could be more generous in places.
Overall though, we see why TestoFuel has remained so popular among bodybuilders for all these years!
Let’s go through the main strengths of this stack, as well as the principal weaknesses.
- Solid dose of D-Aspartic Acid
- Good diversity of ingredients
- Extra focus on libido and energy
There’s a lot that we like about this testosterone booster. Without doubt the biggest strength is the good diversity of ingredients.
First of all, we have an excellent serving of D-Aspartic Acid (D-AA).
D-AA is probably the most reliable natural testosterone booster we know of. It works by stimulating the release of Luteinizing Hormone (LH) from the pituitary gland. When the Lyedig cells in your testes sense the presence of LH, they begin to create and release large quantities of testosterone. You can think of LH as the “trigger” for your body’s testosterone release system, and D-AA is the finger that pulls that trigger!
This is no doubt why D-AAA supplementation has been shown to have such a massive effect on serum LH and testosterone levels (ref).
We think every single testosterone booster needs to contain plenty of D-AA. It is so cheap and readily available – and so damn effective – that leaving it out is never a good idea!
Each daily serving of TestoFuel contains 2,300mg of D-AA. This is all we need to stimulate the release of LH which then causes a release of testosterone from the testes. It is sufficient to see benefits without causing side effects; a serious selling point!
As D-Aspartic Acid is taking care of actually stimulating testosterone release from the testes, other ingredients in TestoFuel are preventing the decline in testosterone levels we usually see from intensive weight training.
We’re of course talking about the Zinc, Magnesium, and Vitamin D servings.
It might sound unbelievable, but we are convinced that deficiencies in zinc, magnesium and Vitamin D are the primary causes of low testosterone in young men today. Most of us work indoors, train indoors, and relax indoors. We eat a diet sparse in minerals like zinc and magnesium (unless your diet is all tree nuts, shellfish and broccoli).
Zinc has a profound effect on testosterone levels. Studies have shown that zinc supplementation is able to prevent a decline in testosterone levels in men subjected to intensive weight training. As the researchers in this study state: “Findings of our study demonstrate that exhaustion exercise led to a significant inhibition of both thyroid hormones and testosterone concentrations, but that 4-week zinc supplementation prevented this inhibition in wrestlers. In conclusion, physiological doses of zinc administration may benefit performance.”
Magnesium is absolutely vital for the proper synthesis of testosterone in humans. Lower magnesium levels correlate closely with lower testosterone levels. Conversely, higher magnesium levels usually correlate nicely with higher testosterone levels. This relationship has been observed in both sedentary and trained men, and it seems to be particularly pronounced in older men (ref).
Like both magnesium and zinc, serum Vitamin D levels are very closely correlated with free and total testosterone levels in humans (ref). Indeed, Vitamin D acts much more like a hormone in the body than a vitamin – it modulates various bodily functions, such as bone formation, calcium absorption, and obviously, testosterone regulation. And like zinc and magnesium, most people in the West are deficient in Vitamin D (especially in the winter months).
TestoFuel provides good doses of these essential nutrients. Most guys will benefit greatly from supplementing with these nutrients on a regular basis, especially if they are constantly doing heavy weight training.
It’s also worth mentioning the 100mg of Asian Red Ginseng.
Ginseng is a very hit-and-miss testosterone booster. Different types of ginseng seem to have different effects; some seem to reliably increase testosterone, others seem to do nothing at all.
It also seems to be quite inconsistent across populations; some people get a lot from it, other people seem to be non-responders.
However, robust clinical trials have shown that Asian red ginseng supplementation significantly increases free serum testosterone (as well as other male sex hormones). As you’ll see if you read the cited study, Asian Red Ginseng supplementation seems to reduce prolactin, which is the hormone that tells the body to produce breast milk. If you’re a guy, you definitely want this reduced!
That TestoFuel provides some Asian red Ginseng, and not another, less effective form of ginseng, is a major selling point. That said, we do think it could use more than 100mg. This brings us on to our problems with TestoFuel!
- Low doses in key areas
- No aromatase inhibitor
- Fenugreek boosts libido but not testosterone!
Despite the many strengths listed above, TestoFuel is not perfect. It is actually not market leading; we think there are better testosterone boosters out there. The thing that most clearly separates it from the best, in our opinion, is the lack of an aromatse inhibitor.
Top quality testosterone boosters today often contain a natural aromatase inhibitor.
There are a handful of substances which are able to reduce the action of the enzyme aromatase, which is responsible for the conversion of testosterone into estrogen. Your body likes to balance testosterone and estrogen – it doesn’t care about your gains, just about longevity and survival! By inhibiting aromatase, you slow down the rate of conversion of testosterone into estrogen, which means higher serum testosterone levels!
You will see some cutting-edge products which contain known aromatase inhibitors. The most common one used today is luteolin. We think this has the most solid scientific backing of all the supposed aromatase inhibitors.
Unfortunately, TestoFuel doesn’t contain any of this incredible natural testosterone booster. If the primary cause of low testosterone for you is too much aromatase, then TestoFuel’s results are going to be limited!
Another notable absence from TestoFuel is anything to bind to Sex Hormone Binding Globulin.
Allow us to explain.
Sex Hormone Binding Globulin is a protein which binds to estrogen, DHT, and testosterone. Once it has bound to these proteins, they cannot act on their respective receptors. This means that testosterone cannot exert any kind of androgenic effect on the body.
To put that another way, SHBG renders testosterone useless.
That is why some cutting-edge testosterone boosters today provide substances which preferentially bind to SHBG. In doing so, they ‘take the bullet’ for testosterone as it were. The end result is more free testosterone, and by extension, increased strength, faster muscle gains, etc.
If you’re going to try to ramp up your body’s own production of testosterone, it’s really important that you also try to minimize aromatase activity and SHBG activity. Both of these will render excess testosterone effectively useless.
The fact that TestoFuel lacks these increasingly commonplace ingredients is a major issue. It is no doubt a result of the fact that TestoFuel was formulated a few years ago. It doesn’t make it a bad testosterone booster – it’s just that some products have a more rounded, comprehensive formula.
The final weakness of TestoFuel’s formula is the use of Fenugreek.
You’ll find a lot of stuff written about fenugreek online. 90% of the time, it’s all positive. There are lots of fitness and supplement review sites out there which claim that fenugreek is a potent testosterone booster. They say that it can raise free testosterone levels in men in just a few weeks. To back up these claims, you’ll often see them cite this study.
However, there’s a big problem here: that study found fenugreek to be INEFFECTIVE FOR RAISING TESTOSTERONE!
Rather, the researchers found that fenugreek increased sex drive without influencing hormonal parameters in any way.
The researchers in that study used what is supposedly the highest quality fenugreek extract available. They gave participants good doses too – 600mg per day! Yet there was still no effect on testosterone levels.
The fact that it increases libido is not a bad thing. If you’re hammering the iron 5 days per week, then chances are you’re feeling pretty exhausted by the time you get home. If you work a full-time job and have kids, then sex might be the last thing on your mind by the time you hit the sack. So having something to give your libido a boost is definitely a positive.
It’s just that it doesn’t increase sex drive by elevating testosterone levels, which is really what most people using TestoFuel will want.
So What Can It Do?
So we’ve been through the formula and highlighted all the main strengths and weaknesses.
But you might not really care about any of this.
At this point, some of you might be thinking: JUST TELL ME WHAT IT DOES!
In practical terms, we think most people using TestoFuel will experience the following benefits, provided they take the supplement consistently for a couple of weeks at least:
- A notable increase in lean muscle mass
- Faster recovery post-training
- Greater energy levels in the gym
- Increased libido
- Greater confidence and improved mood
If these are the kinds of things you’re looking for from a testosterone booster, then TestoFuel might be perfect for you.
User Reviews – What Are People Saying About TestoFuel?
Independent user reviews are always of limited value when trying to judge a supplement. We have no idea whether or not the people behind the reviews are genuine; we don’t know if they used the product properly; we don’t know what their diet was like; we don’t know what else they were using.
Basically, we don’t know a lot. There’s no guarantee that they were particularly scientific in their approach!
But, one thing user testimonials give us is an insight into how the product is supposed to work, what kind of benefits you can expect, and so on. An abundance of genuine reviews can sometimes tel us whether or not it is a total scam too, which is always useful.
So, let’s take a look at some user generated TestoFuel reviews. We’ll start with the most notable:
Here is a selection of TestoFuel user reviews taken at random from the website and YouTube:
As you can see, TestoFuel has at least given a few guys some really impressive results.
We can’t be certain that these guys weren’t using something else as well as TestoFuel of course.
Judging by some of these results, they could well be using steroids!
But what this does tell us is that TestoFuel isn’t a total scam. It definitely gave these guys something; the transformations found by the dozen online and on the TestoFuel website are no joke!
How To Take TestoFuel
Getting the most out of TestoFuel requires you to use it properly.
By that, we mean using it consistently, on a daily basis, for several weeks.
That is how the ingredients in TestoFuel work best; they take time to build up in your system, and it takes a little longer after that for their effects to become noticeable.
Many people will fail to really get any good results from this or any other testosterone booster simply because they’re lazy, they don’t take it every day, or they don’t give it enough of a chance. There is a reason why the money back guarantee is 90 days and not 14 days!
So when should you take TestoFuel?
Pre-workout or post-workout? In the morning or at night?
To really get the best possible results, we recommend splitting up your daily dose of TestoFuel into 4 equal parts and consuming them at regular intervals throughout the day.
For example, your daily dosing schedule might look like this:
- First serving at 8am with breakfast
- Second serving at 1pm with lunch
- Third serving at 6pm before hitting the gym
- Final serving at 9pm post training
We recommend doing this for a number of reasons.
For one thing, it keeps you nice and topped up with active testosterone boosting agents all day long. Most of the ingredients in TestoFuel take a little while to really have a big impact on your test levels, but some do get to work right away. Splitting up your dose therefore prevents peaks and troughs in testosterone levels.
Another big consideration is side effects. If you take the full dose at once, any side effects you might experience will be more pronounced than if you’d split your daily serving into smaller doses. Side effects will be rare of course, and when they do occur, usually pretty mild. But it’s definitely worth taking the extra precaution of starting small and making sure you aren’t allergic or overly sensitive to anything before taking a full day’s dose all in one go!
TestoFuel Side Effects – Is It Safe?
By far and away the most important consideration for many of you is safety.
You probably came to this review looking for the answer to some very simple questions:
Will TestoFuel cause side effects?
What about long-term safety?
In our opinion, TestoFuel is highly unlikely to cause side effects in the vast majority of users.
It is made of all-natural ingredients which have been thoroughly tested in clinical trials and have been found to be both effective and safe for human consumption.
In studies carried out on the ingredients used in TestoFuel, there is never any mention of serious side effects. The only adverse effects we have ever come across with regards to these ingredients are things like digestive discomfort. Even then, occurrence is quite rare.
So long as you use TestoFuel as directed, and you don’t have any allergies or pre-existing conditions which make it unsuitable, you should be fine.
That said, it’s genuinely very important that you read the label carefully and make sure that you are not allergic or highly sensitive to any of the ingredients in TestoFuel. It is rare for someone to be adversely affected by the ingredients in this testosterone booster, but it is possible.
You need to talk to your doctor and ensure that TestoFuel is not going to interact badly with any medications you’re currently on, any other supplements you might be using, and so on.
You MUST be aware of the following things while reading our reviews:
- We are not doctors
- This isn’t medical advice
- We are simply presenting our opinion, based on our own research and experience
Your unique medical history is relevant to safety considerations. We don’t know you or your medical history. We are just presenting our opinion based on the average user, our experience, and our research. Just because TestoFuel looks safe for 99% of users doesn’t mean it will definitely be safe for you. You need to do your own research carefully and get proper advice from your regular family physician before continuing.
Pricing – How Much Does TestoFuel Cost?
In our opinion, TestoFuel is definitely worth the money.
The potential results from using this potent, reliable and seemingly very safe testosterone booster are well worth the very reasonable $65.00/month supply price tag.
That works out at about €45, or around £40.
So for each day that you are using TestoFuel – even when you take the most expensive purchase option – it works out at around $2.09 per day for a 31 day month.
Of course, this gets an awful lot cheaper when you buy multiple boxes at once. If you opt for the Ultimate Mass Gainer Package – where you get a 4 boxes plus a couple of eBooks – the price comes down to $48.75 per box.
That works out at about $1.50 per daily serving.
For the potential gains you’re looking at, that is an ABSOLUTE BARGAIN!
Buying the 4-box option actually makes TestoFuel significantly cheaper than most other testosterone boosters on the market today. It certainly makes it cheaper than the current market leaders.
Money Back Guarantee
It’s also worth taking the money back guarantee into consideration.
TestoFuel comes backed by a 90-day money back guarantee. Users who are not satisfied with the product can return it within 90 days and receive a full refund (terms and conditions apply).
That is how confident Roar Ambition are about their product.
This really makes the ~$48 per month price tag seem even more reasonable!
TestoFuel Review Summary – A Top Notch Testosterone Booster
In our opinion, TestoFuel is a top quality testosterone booster.
Its ingredients are, on the whole, excellent.
Every ingredient has a place here. D-Aspartic Acid and Asian Red Ginseng are absolute staples in modern natural testosterone boosters for a reason – they are devastatingly effective. When used in combination, results are practically inevitable.
The healthy servings of key nutrients ensures that no deficiencies are going to hold you back.
Then to wrap it all up, you have a really nice libido booster to make sure that you can still satisfy your girlfriend after crushing it in the gym every night.
Are there better all-round testosterone boosters out there than TestoFuel?
Yes, we think so.
But this product is probably the best option for young guys who want some extra ‘juice’ in the gym and a little help keeping their girls happy in the bedroom. A great niche product, no doubt about that.
Who Sells TestoFuel?
TestoFuel is made and sold by Roar Ambition. These guys are very reputable supplement manufacturers. They’ve been around for a good few years now. Unlike many other new starters in the bodybuilding world, they’ve managed to stick around! They are based in the UK, although their products are manufactured and shipped worldwide.
Where To Buy TestoFuel
TestoFuel can only be bought directly from the manufacturer. We really respect this way of doing things. It guarantees quality control; third parties can ship faulty or damaged product, they can be late, or their customer service can be awful. There’s also the risk of over-charging. TestoFuel avoids all these problems by selling exclusively through their online store. You can pay in several different currencies, and they ship worldwide. So it doesn’t matter if you’re looking to buy TestoFuel in the UK, in Australia, or the US – you use the same website to buy!
Will TestoFuel Fail A Drugs Test?
No. There are no banned substances in TestoFuel at all. The product only contains natural ingredients that could reasonably be found in the human diet. There’s no synthetic pro-hormones, no stimulants, and nothing that could potentially even become a controlled substance. TestoFuel will not fail a drugs test, and it is future proof.
Can TestoFuel Cause Gyno?
The lack of an aromatase inhibitor might be a worry for some of you. It might seem like TestoFuel is liable to cause gyno. However, we think this is extremely unlikely. TestoFuel increases the body’s natural production of testosterone. This can lead to increased conversion into estrogen, but it is important to remember that TestoFuel is not an exogenous hormone – it isn’t steroids. Your body is not going to have a huge load of extra testosterone to rapidly convert to estrogen. Instead, it triggers a steady, gradual increase in testosterone production in the testes. There’s no sudden change in the body, so there’s no extreme reaction either.
If you do experience gyno while using TestoFuel, stop using it immediately and talk to a doctor. They’ll test your estrogen levels and see what can be done to keep your hormones in a healthy balance.
Can Females Use TestoFuel?
It should be theoretically safe for women to use TestoFuel. However, we don’t think they should if they really want to see results. We think the results they get are going to be significantly less impressive than those achieved by men who use this supplement.
TestoFuel has been specifically designed to take advantage of the testosterone production system in men. The way women produce testosterone is completely different to the way men produce this hormone. Some ingredients in TestoFuel have also been shown to decrease prolactin in men. To our knowledge, these ingredients have not been thoroughly tested in women, but playing around with prolactin is not a good idea if you plan on breast feeding any time soon.
Since the ingredients in TestoFuel are relatively untested in women, we advise serious caution!
