We’ve been seeing advertisements for TestoFuel everywhere lately. It seems that every time we go online to read about bodybuilding, strongman, or pretty much anything strength/sports related, we see prompts for an in-depth TestoFuel review. So, after seeing people writing about this testosterone booster for the hundredth time, we decided to check it out for ourselves and to write our own TestoFuel review – done our way!
After all, we know that you can’t exactly trust the supplement reviews you read online. We’ve already written extensively about the many ways supplement manufacturers try to mislead you.
Who’s to say that all of the glowing TestoFuel reviews out there aren’t just plain wrong?
Maybe the reviewers don’t know how to approach supplementation correctly; maybe they don’t apply the scientific method properly; perhaps they don’t share your exact goals. There are many ways that a supplement review can be unhelpful – some deliberate, some accidental.
We’re going to try to avoid these pitfalls by giving you an objective TestoFuel review, written with your goals in mind (strength, athleticism, muscularity, vitality).
Below you will find everything you really need to know about this incredibly popular testosterone booster. We’ll tell you who makes it, what it does, and how it works. We’ll point out the biggest strengths, and the weak links in the armor.
As always, just let us know in the comments and we’ll get right back to you!
When you’re reviewing a supplement – any supplement – the most important thing to consider is the formula. This might sound obvious, but a lot of people actually just gloss over the formula. Instead, they focus on the manufacturer’s promises, they over-emphasize one (usually unproven) ingredients, and they get drawn in by the buzzwords.
But we know that the formula is everything. Either the ingredients are there to do the job, or they aren’t.
Simple as that!
So let’s take a closer look at TestoFuel’s formula to see what this testosterone booster really has to offer:
What Do We Think?
Overall, that is a surprisingly good formula.
We have to admit that when we first took a look at TestoFuel, we expected it to be a scam. Most testosterone boosters are total rip-offs. We’re especially skeptical of the ones you see exclusively advertised online.
Yet this formula really looks like ti has the potential to deliver on TestoFuel’s promises.
There’s a very good serving of D-Aspartic Acid; this amino acid acts on the hypothalamus-pituitary-gonadal axis, triggering the release of testosterone from the testes. We know this from peer-reviewed clinical trials.
There’s also a very large dose of Vitamin D3, and a healthy dose of K2. Most men in the West are deficient in one or both of these vitamins. This is especially true of people who live in northern America or northern Europe during the winter months, when a lack of sunlight means you quickly eat up your vitamin D stores. It’s also true of people who don’t eat foods rich in K2, like liver, egg yolks, dark meats, etc (so everyone basically).
Then backing these up we have a great combo of herbal extracts and vitamins to increase energy levels, ramp up sex drive, and improve athletic performance.
On the whole, not a bad testosterone booster at all! We’re now going to go through the two key ingredients in TestoFuel, highlighting their main function, and citing some evidence to support our claims.
Vitamin D3 – Everybody knows how important Vitamin D3 is for supporting healthy testosterone levels. Vitamin D3 levels are highly correlated with testosterone levels. Lower Vitamin D almost always means lower testosterone. Low testosterone usually coincides with low Vitamin D levels. This has been demonstrated in large, controlled clinical trials across numerous populations (source). Most guys today are deficient in Vitamin D; you all work in offices all day, and train indoors too. You probably only get about 20 minutes of sunlight per day. Not good enough! For most, supplementation can work wonders.
D-Aspartic Acid – This amino acid acts as a trigger for the pituitary gland to start releasing Luteinizing Hormone (LH). LH is the signal for the Leydig cells in your testes to start releasing more testosterone into the blood. So in effect, D-Aspartic Acid acts as an indirect trigger for the release of more testosterone from the testes. This is why hard, clinical trials have found D-Aspartic Acid supplementation to be so effective at raising testosterone levels (source).
Siberian Ginseng – This is probably one of the natural testosterone boosters that we’re most convinced about. Several studies have found that Siberian Ginseng supplementation leads to higher levels of pretty much every androgenic hormone, and a decrease in prolactin (source). Prolactin is the hormone that makes women produce breast milk. It decreases testosterone – lowering it is a major benefit to anyone looking to maximize muscularity and manliness.
The other ingredients, to our minds, are really more supporting ingredients. They absolutely have an effect, but they don’t pull the same weight as Ginseng and D-Aspartic Acid. They’re really here to juice up the two workhorses of the TestoFuel formula.
In that sense, we disagree with most TestoFuel reviews, like the one published by LIVE Magazine. These guys are right to highlight how much of an effect every ingredient in TestoFuel can have on testosterone levels (with the exception of Fenugreek – more on this in a bit). But we think they, and all the other major supplement review sites out there, over-estimate the relative importance of things like Oyster Extract and Vitamin K2.
Vitamin K2 does support healthy testosterone levels. However, you should really try to get more from your diet.
The same is true for Oyster Extract and Fenugreek. Both of these substances will help increase sexual appetite, but you should do your best to eat more seafood and maybe start adding Fenugreek to meals rather than paying for expensive supplements.
Is TestoFuel Safe?
In our opinion, this is a pretty darn safe testosterone booster.
The ingredients in TestoFuel aren’t known for their serious side effects. It uses extracts of herbs, shellfish concentrates, amino acids, minerals, and vitamins – all things you might regularly consume as part of your regular diet. We therefore doubt many of you are going to have a serious reaction to this stuff.
On top of that, every ingredient in TestoFuel has been tested both in vitro and in vivo, on rats and in humans. Each one has been found to be generally safe for regular human consumption, even in concentrated form.
The doses are all well within the normal ranges we expect from nutritional supplements.
To put it bluntly, TestoFuel looks perfectly safe for us.
That said, it’s important that you make sure you don’t have any allergies to the ingredients in TestoFuel, or any pre-existing medical conditions that make this testosterone booster dangerous for you. To get the best advice possible, we strongly advise you to talk to your family doctor!
