TestoFuel vs Animal Stak

A battle of the big guns, but who has the most effective weapon here. Here we have two of the best testosterone boosters in terms of popularity, but which will be the most effective? TestoFuel vs Animal Stak promises to be a good stand off.

With so many testosterone boosters on the market it is a bit of a minefield, but if you fail to do your research the effects could blow up in your face and leave you wishing you had read the label.

That is where we at CLM come in, we help you to stay away from anything that is potentially dangerous or ineffective. Basically, we don’t want you to waste your money or put your health at risk.

So, for either of these two T boosters to be recommended by us they must pass a few tests, starting with the basics. A good testosterone booster therefore should:

  • Increase T levels
  • Enhance Strength
  • Get You Those Big Muscle Pumps
  • Be Safe
  • Increase Energy

Time to see which of these two today can do all of these, starting with getting to know the companies a bit better.

TestoFuel vs Animal Stak – Who Makes These Products?

Roar Ambition

Testosterone Booster - TestoFuel box bottle

The people behind TestoFuel are Roar Ambition, a supplement company who has a great reputation.

Not only do they have a generous money back guarantee (they obviously back their product), but they also review their ingredients list and amend their supplement often to ensure their customers are getting the best possible product at that time.

We also like their endorsements. None other than former Mr. Universe Robby Robinson puts his name to this product and the fact that he looks the way he does in his 70’s shows the quality of TestoFuel.

They are also the people behind the popular fat burner Instant Knockout. This is endorsed by UFC fighter Diego Sanchez who uses it to make weight before a bout.

With such good names using these products, it does bode well.

Universal Nutrition

The people that make Animal Stak are Universal Nutrition and they have a legacy in the bodybuilding and supplements industry that goes way back to the 70’s.

Their extensive range of products means you can pick up just about anything from their website including pre workouts and plenty of merchandise. They seem to pride themselves on making some really potent products but we will analyze if this is actually a good thing or if it can land you in trouble.

With a super macho website that isn’t the easiest to navigate you can find what you are looking for after a while.

TestoFuel vs Animal Stak Ingredients

This is where we can really tell if either of these T boosters is worth your time.

From the off, we can see one major disappointment in that Animal Stak uses many proprietary blends. One makes things difficult but to have several is just a nightmare.

It is difficult to tell if a product is ineffective or even dangerous since the dosages are not revealed.

We will crack on and see what we can find out still.

TestoFuel vs Animal Stak Mutual Ingredients


A top testosterone booster, in fact, your body cannot create more testosterone without it.

It is great for many reasons which is why it is such an important ingredient. It can prohibit prolactin which is good news for your T levels and it is also known to stop your body from using up Testosterone during a workout.

The dosage of 10 mg in TestoFuel is more than enough to benefit your testosterone levels. Animal Stak has included 30 mg. This might seem better but if your daily intake is over 40 mg then you run the risk of potential side effects.testofuel-vs-animal-stak

Since it is found in many everyday foods from red meat, dairy and seafood this is quite a high dosage from Animal Stak, meaning TestoFuel seems safer from the start.

Vitamin B6

Low levels of Vitamin B6 in your body are often linked to low testosterone, so supplementing Vitamin B6 is a wise choice.

It is thought to be good for blocking testosterone binding cell receptors, freeing up more testosterone for your body to use.

The 5 mg in TestoFuel and 10.5 mg in Animal Stak will both do a job here.


If you are athletic then you will feel the benefits for your T more than those who are not. But magnesium still has an effect for those who are not as athletic, however.

It inhibits the Sex Hormone Binding Globulin – this protein strips your T of its potency so less of it in your body is a good thing.

TestoFuel have included 200 mg and Animal Stak 450 mg. Since the recommended daily allowance is around 400 mg a day, Animal Staks dosage is a bit high for us.

TestoFuel vs Animal Stak Individual Ingredients


Vitamin D3

A great inclusion here as this is one of the top testosterone boosters around. Low levels of D3 = low testosterone and it might be more important than ever to supplement this ingredient since many of us are deficient in it.

We create our own D3 through our skin’s exposure to direct sunlight, we obviously aren’t getting enough rays to be deficient.

There is an optimal dosage of 5,000 IU included in TestoFuel.

D-Aspartic Acid

Another key testosterone boosting ingredient, TestoFuel have done their research here as this ingredient stimulates your brain into releasing the luteinizing hormone. From here it communicates with the testes to create and release more testosterone.

It has a famous reputation and countless studies to vouch for its effectiveness.

The 2,300 mg included in TestoFuel is well within the 2-3,000 mg needed for an optimal dosage.

Animal Stak

Stinging Nettle

About time this pesky leaf did something good in return for the times it made us itch as kids! Well, this is actually a decent ingredient as it is another that stops SHBG, this, in turn, prevents estrogen levels from increasing which means your body’s testosterone can thrive.

We say this is an excellent ingredient, yet we have no idea if the dosage is optimal or completely ineffective since it is part of one of the proprietary blends within Animal Stak.


The problem with this ingredient is it can put you at risk of developing unwanted side effects such as gastrointestinal upset if the dosage is too high.

It is thought to be good for those big muscle pumps but there is the risk of the side effects that put us off. Especially since it is part of a proprietary blend – we have no idea how much of this there is in Animal Stak!

TestoFuel vs Animal Stak Side Effects

This is one of the best things about TestoFuel because they only use 100% natural ingredients at optimal dosages, you are only at risk of side effects if you have an allergy to the Oyster Extract in this product.

Animal Stak, however, contains Arginine which can potentially cause a gastrointestinal upset as well as diarrhea, (see examine.com)  not what you want from a supplement!

For us the real quality testosterone booster was TestoFuel.

Any supplement that is 100% safe to use is off to a great start and 95% of supplements fall at this hurdle.

The fact is you don’t have to compromise and can find some great supplements that won’t cause you harm. On top of this TestoFuel is really effective thanks to the many optimal dosages that are carefully thought through and not often seen, to be honest.

Animal Stak has some decent ingredients and we can see why with their eye-catching packaging and marketing, they do so well in terms of numbers.

The problem lies in the proprietary blends really with Animal Stak, any product that doesn’t reveal the dosages has the potential to be harmful and cause side effects, especially if the ingredients aren’t all good ones.

The other problem is the potential of side effects from Arginine, look out for this ingredient if you are continuing your search for a testosterone booster.

There are some top ingredients in TestoFuel that really make it one of the best out there which is why we have no problem with recommending it.
