#1 From All Testofuel Review And Breakdown

Have you ever read a men’s magazine?
Flipping through the pages you will see all sorts of crazy testosterone supplements, each name sounding more like a dinosaur than the last.
Anovar, DBol, Velosoraptorvar.
Pretty much all of these testosterone boosters are synthetic, unnatural & possibly unsafe.
On the contrary, check out some natural testosterone boosters. For the most part they look ancient like your Grandma made them in her kitchen.
What if there was a badass testosterone booster that looked the part, worked and was still completely all natural.
Well there is.
There are a few actually.
But one of them is Testofuel, which is the focus of this article.
(Another one is tongkat ali extract – but we have a whole other article for that)
Testofuel is a new player on the testosterone boosting market. It looks the part, and has all the glamorous marketing that most test boosters do, but does it hold up to the hype?
This is what we intend to answer.
Are you ready?
I think that people get scared when they see a product with fancy marketing now-a-days, because there are a lot of scams out there. But you can’t judge a book by it’s cover.
First off, it’s important to note that Testofuel is 100% all natural. It is exactly as it’s name is branded, a fuel for testosterone.
But will this fuel take you cross country or leave you stranded in the middle of the dessert?
To determine that, first lets look at each ingredient of Testofuel and break it down one by one. Before we get into

Testofuel Ingredients Breakdown

Unlike other Testosterone boosters on the market, Testofuel is not packed large amounts of different ingredients to appeal to label readers.
It only contains essential ingredients that actually work.
Quality over quantity.
Here is a list of those ingredients for you, backed up with science.

TestoFuel Ingredients Overview

testofuel ingredients

Testofuel Ingredient #1: D-Aspartic Acid

testofuel reviews
D-aspartic acid is the newest hype in natural testosterone boosters.
It is a non essential amino acid that has several functions ranging from neurotransmission to being a natural testosterone booster.

How Does it Work?

The magic of d-aspatic acid is that it can boost your testosterone in multiple ways. First it signals the production of testosterone production in the testes. Second it acts on the purtiitary gland to signal the release of more testosterone. And last, it plays a huge role in the conversion of cholesterol to testosterone. And for anyone who knows anything about testosterone, it is literally made from cholesterol.
(BTW – Don’t be scared of eating cholesterol – Learn the truth)
Most studies suggest a serving of no more than 3000 mg per day. Testofuel contains a respectable 2300 mg per day.
1) A 2008 study looked at d-aspartic acid in mallards. After 60 minutes of d-aspartic acid supplementation, testosterone levels in the blood were significantly higher. After 120 minutes they rose even more. [1]
2) The same scientific team in study 1 gave D-Aspartic Acid to rats and humans for 12 days. At the end of the study, both the luteinizing hormones and testosterone levels were higher in rats and human by a whopping 42% average. [2]
3) Useful article: Don’t use d-aspartic acid until you read this

TestoFuel Ingredient #2: Magnesiumtestofuel reviews

Magnesium is a big player in the testosterone boosting game that almost nobody knows about.

How Does it Work?

And quite frankly, I didn’t until I was enlightened by an article by Andrew Best on how magnesium boosts testosterone levels.
The article is awesome, and it links to 3 studies that show how Magnesium supplementation significantly increases both free and total testosterone in men.
Don’t feel like reading? I’ll link to the studies below because I’m a nice guy.
Testofuel contains 200 mg of magnesium per serving.
1) A 4-week study [3] looked at the blood levels of both free and total testosterone in 3 groups of men. Group 1 was a group of sedentary men who took magnesium supplements (10mg per kg of body weight per day). Group 2 was a group of tae kwon do athletes. They also took magnesium supplements each day (10mg per kg of body weight per day) AND did tae kwon do exercises for between 1 hour 30 minutes and 2 hours each day. Group 3 was another group of tae kwon do athletes. They did the same tae kwon do exercises as group 2 (90-120 minutes per day) but took ZERO magnesium supplements.
The results were:
ALL 3 groups of men saw increases in their levels of both free and total testosterone after the study. The group which took magnesium AND did tae kwon do saw their testosterone levels increase the most. The group of sedentary men who sat around taking magnesium supplements still saw significant increases in testosterone.
2) A 7-week double blind study [4] showed that magnesium supplementation makes you stronger in at least 2 ways. One is from a direct increase in testosterone.
3) The third study [5] showed that higher levels of magnesium were associated with higher levels of testosterone (both free and total) and of insulin-like growth factor (IGF-1).

TestoFuel Ingredient #3: Vitamin D3testofuel reviews

Vitamin D is an essential nutrient that almost all Americans are chronically deficient in, due to too little exposure to sunlight and overuse of sunscreen.
Deficiency in vitamin D has been shown over and over to significantly lower free testosterone levels, along with a host of other ailments.
Testofuel contains 5,000 IU per serving which is a modest dose. This alone will help you feel better.

How Does it Work?

Just by correcting a vitamin d deficiency you can lose fatigue, gain energy and mood back, and yes – increase your testosterone. (But it takes month’s for a deficiency to be corrected)
1) A study [6] showed that when they dosed one group of men with vitamin D, and another with placebo, showed a a significant increase in total testosterone levels (from 10.7 ± 3.9 nmol/l to 13.4 ± 4.7 nmol/l; p < 0.001), bioactive testosterone (from 5.21 ± 1.87 nmol/l to 6.25 ± 2.01 nmol/l; p = 0.001), and free testosterone levels (from 0.222 ± 0.080 nmol/l to 0.267 ± 0.087 nmol/l; p = 0.001) in the vitamin D supplemented group. Each man took 3,300 IU’s of vitamin D during the study. (That’s less than whats in Testofuel)

Testofuel Ingredient #4: Vitamin K2

How Does It Work?

I’ll be honest, I had no idea what Vitamin K did, so I had to look it up. But low and behold it has been shown to help maintain plasma and testes levels of testosterone. It also helps prevent calcification of arteries and other soft tissues.
Tasteful contains 180 mcg of Vitamin K
In a study [7], dietary vitamin K was shown to alleviate the reduction in testosterone production induced by lipopolysaccharide administration in rat testis. Basically, when you eat vitamin K, it effects the level of Vitamin K in your testes. Testicular vitamin K then helps maintain steady levels of testosterone.

Testofuel Ingredient #5: Vitamin B6

Vitamin B6 is essential for many functions in your body, one of which is testosterone production.

How Does It Work?

It helps stimulate androgen (a precursor to testosterone) receptors, which in turn up regulates the production of testosterone in your testes. On top of that, it may naturally suppress estrogen in your body.
Testofuel contains 5 mg of Vitamin B6 per serving (250% of your daily value)
In a study [8] male rats were put on a vitamin B6-free diet for 4 weeks, to cause a moderately severe degree of vitamin B6 depletion. The result was a significant reduction in the circulating concentration of testosterone in plasma in the rats.

Testofuel Ingredient #6: Zinctestofuel reviews

Zinc is a notorious testosterone booster, which is why ZMA’s are so popular in bodybuilding (That’s Zinc & Magnesium Aspartate).
Just taking Zinc alone is enough to boost your testosterone, and your sperm count. (50 other ways to boost our sperm count)
Testofuel contains 10 mg of Zinc per serving.
1) In this study [9], just supplementing with zinc for just six weeks was shown to boost testosterone levels.
2) Research [10] has also shown that restricting your zinc levels will significantly decrease your testosterone levels.

Testofuel Ingredient #7: Oyster Extract

testofuel reviews
Have you ever heard the cliche that eating oysters is going to make you have a wild night of sex?
Well they weren’t lying.
Oysters are one of the most notorious aphrodisiacs out there. (Here’s 20 more aphrodisiacs)

How Does It Work?

This is mainly because of the high amount of Zinc they contain (10X more than beef). Oysters also contain over 50 other trace elements needed by the body, including vitamins, amino acids, taurine, omega 3 & 6 fish oil and much more. All resulting in an increase in testosterone and a higher sex drive.
This is where the sex drive that our human guinea pig experienced comes from. (We’ll talk more about this later)
Testofuel contains 100 mg of oyster extract.

Testofuel Ingredient #8: Fenugreek

Fenugreek is an herb found as an ingredient in many curries. It is shown to boost your testosterone levels but more notably it has been shown to have a great effect on your sexual arousal and libido.
Testofuel contains 100 mg on Fenugreek.
1) One study [11] gave 60 healthy men either a placebo or a supplement containing fenugreek, and other minerals, everyday for 6 weeks. At the end of the study, men who took the fenugreek showed an improvement in several aspects of libido (such as sexual arousal and orgasm).
2) A small study [12] in The Journal of the International Society of Sports Nutrition showed that Fenugreek helped increase the testosterone levels in adult males.

Testofuel Ingredient #9: Siberian Ginseng testofuel reviews

Ginseng is a powerful herb and adaptogenic (helps your body adapt to stress) that is used all over the world.

How Does it Work?

It has been proven to increase your sex hormones which in turn increases your body’s production of testosterone.
Ginseng also raises the levels of adrenocorticotropic hormone (ACTH) and adrenaline. Low levels of ACTH and adrenaline have been correlated with lower testosterone levels.
Testofuel contains 100 mg of Siberian Ginseng
1) In this study [13], concentrated extract of Siberian Ginseng significantly increased mounting and pelvic thrusting frequency and numbers of intromission of male mice and increased serum testosterone concentration.
2) Siberian Ginseng also lowers the rise of stress hormones during physical stress, which is awesome. [14]
Every single ingredient in Testofuel has been proven to boost your testosterone on it’s own. So logic makes me believe that while used together, they will have a compounded effect.
Scientifically, there is no doubt that Testofuel will boost your testosterone levels.
But what did we think off paper?


Our In House Testofuel Review

Breaking down ingredients is all well and good, and Testofuel looks great on paper. But this would be a horrible review if we didn’t actually use it and say what we thought.
So enter my human Guinea pig, Thomas Bandov:
testofuel review
Thomas is an experienced gym goer and an experience testosterone booster. He has used tongakt ali extract, Anovar and a punch of other high powered synthetic testosterone boosters. So if Testofuel did anything at all, he would feel it.

Testofuel results:

He felt it. He said he noticed a marked increase in his sex drive specifically and more energy and output in the gym. He was putting up more weight and feeling more powerful. If he didn’t feel it, regardless of how it looks on paper, this review wouldn’t see the light of day (like the dozens of other products we get sent every month).
Was it as powerful as the strong stuff? No.
But not everyone wants the strong stuff, which comes with a risk of Gyno, acne and all sorts of other stuff.
The way I see Testofuel is kind of like a multi-vitamin for your testosterone levels.
If you are doing everything right to increase your testosterone naturally, and eating a pro testosterone diet with adequate cholesterol, then Testofuel is going to help you convert your hard earned efforts in higher testosterone levels.

What We Recommend:

Listen, you are obviously reading this because you are interested in boosting your testosterone or taking Testofuel. Testofuel will boost your testosterone levels, and maybe even make you feel better overall, but it can be pricey for some.
If you are money conscious, just buy regular d-aspartic acid.
If your anal retentive, buy each active ingredient separate, take 9 pills a day and save $10.
If you want to try it, purchase the 3 month supply. Why? Because this is the only option that offers a 100% money back guarantee (-$35 Fee).
If you want to be an asshole purchase the 3 month supply, use it and get a refund even if it works. (Don’t do that)
They believe in their product, and after 90 days they expect you to be pleased or they will give you your money back. That’s their biggest upsell to me. Check out Testofuel.com to learn more and try it out.

    Hello, I was wondering about the pros and cons of taking a recommended dose of Siberian ginseng while taking test boosters (testofuel)? I would love to hear a reply back, thanks.

    1. yo

      yo yo. No cons only pros (unless you eat like a kilogram of the ginseng a day. Then you will get diharrea)

  2. Dale

    I can’t believe that Roar Ambition can have the top two testosterone boosters and the best fat burner (Instant Knock Out) on every site on Google, when no two sites can even agree on the top Preworkout. Scam

    1. Floyd

      I’m not sure about TestoFuel , but instant knockout most definitely works. I’ve used it for 2 months and I’m happy with it.
      But the thing you have to remember is , any fat burner you take has to be complemented with a proper diet and workouts. I’ve been doing both so I can’t say for sure that it’s the Instant Knockout alone that gives results , it could be just my workouts and diet , but the fact is , I have got results.

  3. Sean Russell

    Tried to email you Russell. Sorry for your experience, truly just doing the best we can here and our tests have shown benefit from testofuel. Not out here to scam guys. GL with future purchases.

    1. Brian

      I think something that needs to be mentioned is time on testo fuel and each body growth/adaptation type. I’ve been taking testo fuel and didn’t notice any results in the first 2 1/2 weeks. I stuck with it and by the middle of my second month, I noticed huge gains. I feel it just took time for my body chemistry to balance out with the added vitamins my body had been lacking.
      I read an article that in he early 1900’s testosterone in males started dropping in their 60’s. Currently researchers are saying it is now dropping in the late 30’s. Well, I’m 42 and felt tired all he time, my workouts were not the same as when I was in my 20’s-30’s. So, for me testofuel has helped with energy and my workouts are awesome.

  4. Silvan Popovic

    Anavar is not a test booster. It is suppressing the testesteron if taking at a higher dosage.

  5. stelios

    Hi there,
    Is there for an excess hair growth while using Testofuel?

  6. Josh

    I love TestoFuel, used it for a while and it really helped me get more muscle gain from my workouts and generally just have more energy. I really noticed the difference personally.

  7. jay

    im having to decide between testofuel and factor 2 if they are twins in the supplement market i will go by price but if one is better than the other id like to know before buying the weaker of the two

  8. cathal

    Just saw this product a few days ago and only learning about it. It sounds really good. Anybody from the Dublin area take take this product I would be keen to chat

  9. Sonu

    Can we use it in summer and with milk?

    1. James Hardie

      Yes to both

      1. Amarjit

        Thanks James

  10. Lee

    Yes, I agree TestoFuel is a top brand in the market. I get a lot of users asking for a good opinion on this testosterone booster.
