In this TestoFuel review I discuss some concerns over the ingredients in this testosterone booster.
You will probably not get this information on any other review site because TestoFuel (and Prime Male) have an incredibly successful affiliate program ran by StackedBrands.com which pays very lucrative commissions for each sale.
This is why you will often see both these products ranked #1 and #2 on most review websites.
That does not inherently mean these are bad products by any means. Many great nutritional companies offer affiliate sales programs.
StackedBrands.com is just the most successful one I know of so they get the most attention.

What I Like About TestoFuel
Testofuel does have a few really strong points to be said about it.
⇒ Strong Vitamin and Mineral Support with ZMA
They do a great job with their vitamin and mineral support and have strong doses of scientifically proven ingredients including vitamin D.
I wish they would have included boron as it is one of the most powerful testosterone boosting minerals on the planet but you do get a strong dose of the ZMA complex which is great.
⇒ Strong Doses Overall
I don’t like their choice of herbal ingredients but they do give strong doses on everything with the exception of fenugreek and panax ginseng.
⇒ Made in the USA in an FDA and GMP Certified Facility
With so many supplement companies trying to cut corners and save costs everywhere they can, it’s always great to see TestoFuel come through with the FDA and GMP certified facilities.
What I Am 50/50 On
Panax ginseng is great to supplement with for boosting testosterone levels.
However, 100 mg is a low dose and if this extract was standardized to 30% ginsenosides it wouldn’t be “too bad”.
But they don’t tell what the ginsenosides is at which probably means it is not standardized and that could render such a low dose effectively useless.
What I Don’t Like About TestoFuel
Case studies are often misrepresented by supplement companies and those touting D-Aspartic Acid are most certainly playing with smoke and mirrors.
In human studies, D-Aspartic Acid has been shown to boost testosterone in infertile men within the first 6 – 12 days. However, after just 1 month, their testosterone levels decreased back to baseline.
In other words, unless you are an infertile man and looking for a very temporary boost, it’s probably not going to do much for you.
In fact, one study actually showed it may decrease testosterone. (study)
Fenugreek is used to treat menopausal symptoms, induce childbirth, and increase the supply of breast milk in lactating mothers.
So why is it in so many testosterone boosters on the market today?
Because of a patented extraction method called “Testofen” which used “in-house” studies to try and validate it as a miracle testosterone booster.
Interestingly, Nugenix which helped push Testofen into the limelight by running a series of extremely costly ads, doesn’t even use that extraction method in their own Ultimate Testosterone product, opting instead for regular Fenugreek Extract.
We have yet to find a non-sponsored study on either Fenugreek or Testofen showing any improvement in testosterone levels but there are a lot of studies showing no increase.
Even if you are a fan of fenugreek though, 100 mg is simply not enough to make a difference.
⇒ Vitamin K2
This is a pretty unique ingredient to see in a testosterone booster and because of that it looks both cool and important on the label.
However, it is simply unproven in humans.
Your body can convert K1 which is plentiful in leafy greens, into K2 and a lot of people do not eat enough greens to get sufficient amounts of K2 after the conversion process.
So the immediate conclusion some people come to is that they must need to supplement with it.
I’m not suggesting that supplementing with K2 is bad, it’s just that no human studies have shown a boost in testosterone production.
There has been a test on rats showing an increase but the amount taken in the study would be at an unsafe dose when given to humans.
Until a test shows some kind of testosterone increase in humans, there is just no reason to think there it would be effective.
You can read about eating oysters and boosting testosterone in the link above and I think eating oysters is a good idea.
So why is it under the do not like column?
The single biggest benefit you will get from oysters or its extract is Zinc! Even according to TestoFuels own blog post about it they only talk about getting zinc.
That’s all fine and dandy but there is already zinc in the formulation so there was simply no reason to include oyster extract in the formulation other than its a bit unique so it looks cool on the label.
⇒ Dye is Listed In TestoFuel’s Ingredients
FD&C Red #40 is listed in the ingredients.
At best food dyes have no positive benefit for your health. At worst, according to Consumer watchdog CSPI they can cause a wide range of health issues such as hyperactivity, allergic reactions and cancer.
The only reason to dye a capsule is to try and make it look cool.
Does Testofuel Work?
I completely disagree with TestoFuel’s choices of herbal testosterone boosters overall and at $65 for a bottle it’s very expensive.
They do give big discounts if you buy 3 bottles at a time including a 4th bottle for free but that will still run you close to $200.
If you really want to supplement with DAA and Fenugreek (which I advise against) than I would suggest you take a look at my Evl Test Review.
I believe it to be a far superior product and it is far cheaper.
Where to Buy TestoFuel?
As far as I know the only place you can buy it is directly from their website.
Force X7 by Alpha Wolf Nutrition is the only multi-ingredient, natural T booster iTestosterone recommends.
Featuring KSM-66, Shilajit and Longjack which all made our natural testosterone supplements that really work list.
