Fact Checked

This Testoboost review will lift the lid on this testosterone booster! It’s definitely essential reading if you are considering taking control of your T-levels.

Let me put this to you:

In life, hard work isn’t always enough. We push ourselves hard in the workplace, rack up the overtime and complete every project to the best of our ability. But still the promotion or salary raise doesn’t come.

You know exactly what I’m talking about, right?

It’s the same with our physical training. We put in the gym hours, eat healthily and watch the protein. But often we are not getting the results we deserve.

It appears there is an answer.

Testosterone boosters have been shown to take results to the absolute max! Guys taking these supplements have piled on muscle like beasts, seen 20-25% increases in their presses and have the stamina to power through the hardest of sessions.

But, there’s always a downside.

Testosterone boosters have flooded the market. The seriously powerful and effective supplements can become lost amongst the dross.

That’s why I’m here!

This Testoboost article will make clear whether this T-booster is on the top of the pile or can just be forgotten about. I will let you know its ingredients, its potency and answer the important question – does Testoboost work?

Let’s get this show on the road!

Warning! Dear Testoboost reader: Click here to see why this booster did NOT make it to the list of Top 5 Test Boosters.

Testoboost Review

Guys, I want to kick off with a bit of clarification.

Here’s why:

Testoboost is not the most original name for a testosterone booster. There are at least five other T-boosters with the same name on the market!

So, this Testoboost review is for the supplement made by Arazo Nutrition. But still, that involves some more complications!

Get this:

You may find an identical product, with the same Testoboost name, same ingredients and same packaging, marketed by Bioscience Nutrition. Only the manufacturer’s name is different

It appears that Bioscience recently changed its brand to Arazo, and there are still a lot of the old products kicking around.

Listen up:

Arazo Nutrition state on their official website that they have over 10 years’ experience in nutrition supplements. Although I was unable to find any evidence to verify this.

Testoboost is a supplement which claims to boost T-levels naturally through its safe ingredients. It promises it will:

  • Spike athletic performance
  • Raise testosterone levels
  • Increase stamina
  • Enhance libido and sex drive
  • Boost energy
  • Increase focus
  • Build muscle mass

To be fair, these are the usual claims of most testosterone boosters on the market. And, the serious players can achieve these results.

Later in this Testoboost review, we will see if this supplement is one of those players, or if it should just be confined to the bench.

Who Should Use Testoboost?

Broscience Testoboost review thumbs

It’s too early in this Testoboost review to say whether it is effective or not. It could be the case that, after reading this article, you decide it is not for you anyway!

But bear with me!

Before we get going, Testoboost is designed for guys who:

  • Have hit a plateau in muscle gain and need a kick-start
  • Through age or genetics, have found their T-levels dropping
  • Want the sex drive and libido of a horny rabbit
  • Require more stamina to knock out extra reps
  • Demand faster recovery time in order to hit the gym more often
  • Want to raise their game and lift the really heavy iron

If you are nodding your head while reading that list, then testosterone boosters could be your thing!

Who Should Not Use Testoboost?

I know what you’re thinking.

What guy doesn’t want all those amazing benefits?

Well, here’s the truth:

Testoboost, and testosterone boosters across the board, are not ideal for everyone. People who should not use Testoboost include:

  • Sex animals – if you are always ready to get down to some serious bedroom action and your erections are like concrete pillars, you probably have enough testosterone
  • Kids – T-boosters are products for the big boys, they should not be taken by guys under 18 years
  • Ladies – there are specific products designed with the female body in mind. Use those instead
  • Injection junkies – if sticking a hypodermic into your biceps is your thing, T-boosters are not for you. Unlike steroids, these supplements are safe and natural
  • Muscle dreamers – if you think you can get stacked just by swallowing a pill, forget it. T-boosters reward you tenfold for the work you put in. They are not a replacement for genuine gym work
  • New bros in the gym – just come to bodybuilding? Then welcome! But first, get to know the ropes. Learn the equipment, understand training and diet. Then think about supplementation.

Now all that’s out of the way, let’s get down to business in this Testoboost review.

How Does Testoboost Work?

Broscience Testoboost review work

To write a detailed Testoboost review, I tried hard to find information on how this product works. Both the official Testoboost website and the Amazon page were examined, but with few results.

They do not indicate the biological functions of this booster.

It’s like this:

All the marketing blurb indicates is that, through its natural formula, Testoboost will raise T-levels. After that, it becomes very sketchy.

So, assuming that Testoboost does push your testosterone into overdrive, you can expect:

Improved Stamina and Energy Levels

Raising testosterone levels has the effect of boosting nitric oxide production.1

And that’s important.

Nitric oxide is a vasodilator, that is, it opens up the blood vessels. This means that more oxygen can reach the muscles, which is required for them to function.

More oxygen = more stamina and energy = more reps = larger muscles

Fuels Muscle Protein Synthesis

Broscience Testoboost review muscle

We all know the pain that follows a mammoth session!

In many ways, it’s satisfying. It means the muscles have been worked damn hard and the muscle fibers are damaged. And we know what that means!

They will rebuild larger and stronger.

The muscle strands are rebuilt through muscle protein synthesis; testosterone is essential for this process.

Studies have shown that the more testosterone there is in the body, the faster the protein synthesis occurs.2

Which means:

Muscle piles on faster than ever before!

Raises Libido and Improves Sperm

Since testosterone is the male sex hormone, it makes sense that it has an effect on the all-important bedroom action!

Listen to this:

In your teens, your testosterone levels were at their height. Trust me, they have dropped since then. But during that time, remember how you constantly had sex on your mind?

Well, that’s because of all the testosterone!

The higher the level of this hormone, the more you want to get down and dirty! 3

There’s more:

Through nitric oxide opening up the blood vessels as mentioned earlier in this Testoboost review, your erections will be awesome!

And still more!

The higher your T-levels, the greater your sperm count, semen volume and fertility! 4

The bottom line:

If testosterone is increased, it has astounding physiological benefits.

But does Testoboost have the ingredients to rocket T-levels? In the next section of this Testoboost review we will find out!

Testoboost Ingredients

This is where the truth comes out in this Testoboost review. Are the ingredients worthwhile and, most importantly, do they boost testosterone levels?


A great way to start off this ingredient examination.

In studies, magnesium has been shown to raise testosterone levels in healthy men, which is further enhanced through exercise.5

But caution:

These guys were receiving a dose of around 700 mg, Testoboost contains 200 mg, so will not be as effective.


The ingredients are getting better!

Zinc is one of the most powerful of the proven testosterone boosters, and is present in Testoboost at a healthy dosage too.

Supplementing with zinc will definitely improve T-levels.6

Tribulus Terrestris

Broscience Testoboost review tribulus

Oh, dear.

Things were going so well! Despite popular belief that tribulus can raise testosterone, this has only been shown to be the case in animals, not humans.7

What’s more, there is some evidence that it can enlarge the prostate.8


Found in honey, this extract was thought to inhibit aromatase – the enzyme which converts testosterone into estrogen.

If it worked, it would be beneficial in keeping T-levels at optimum. Unfortunately, research shows that it has little to no effect.9

Horny Goat Weed

This naughty sounding plant has positive effects as an aphrodisiac and blood flow enhancer. This may improve erectile function.10

It has no effect on testosterone levels.


Trials have proven that this plant, also known as Tongkat ali, can increase libido (in rats), improve blood flow and work as an antioxidant.11 12

It has been shown to increase testosterone in guys with hypogonadism, but just restores them to normal levels. There appears no evidence that it can raise T-levels in guys with naturally healthy balls.13

What’s more, the guys in the study had a dosage of 200 mg of Longjack. Testoboost has just 50 mg.

Saw Palmetto

Broscience Testoboost review saw

Extracts from this plant have been shown to reduce prostate size which can improve erection dysfunction issues.14

There is little proof that it can positively affect T-levels.

Hawthorn Berries

I have nothing against helping the heart! Hawthorn berries promote a healthy cardiovascular system.

But I am unsure why they are included in this supplement, after all it is a testosterone booster, not a heart booster.

Cissus Quadrangularis

From traditional Indian medicine, this ingredient is used to help heal fractured bones and improve overall skeletal health.

While both of these attributes are worthwhile, it does nothing to boost testosterone. 16

Testoboost Ingredients Breakdown

So far, the Testoboost ingredients appear quite underwhelming in this Testoboost review.

Now let me give you some advice!

I have put together a list of the most powerful and proven T-boosting ingredients and enhancers. These are the elements you should be looking for in a serious testosterone booster.

This is how Testoboost compares:

  • ✘D-aspartic acid
  • ✘Vitamin D-3
  • ✘Fenugreek
  • ✓Zinc
  • ✘Vitamin B6
  • ✘Vitamin B2
  • ✘Vitamin B5
  • ✘Selenium
  • ✘Ginseng
  • ✘Boron
  • ✘Bioperine

See the top rated testosterone booster that contains all these ingredients.

With just one tick on the list, Testoboost does not perform well.

Testoboost maximum strength seems to lie in its power as a male sexual enhancement pill, rather than a T-booster.

And even then, it’s a poor libido supplement.

Testoboost Side Effects

Broscience Testoboost review side effects

In general, it appears that Testoboost is a product with very few side effects.

This is not surprising, as all the ingredients are FDA approved and 100% natural.

But be aware, some guys have reported:

  • Stomach cramps
  • Migraines
  • Nausea
  • Diarrhea

Testoboost Before After Results

For this Testoboost review, I have already examined the ingredients and was not too impressed.

But, maybe I am not giving the product the credit its due!

This T-booster promised results of muscle gain, increased energy and more focus. This is what guys have been experiencing:

my energy level when working out has increased significantly”

Sam Stephens

“I have experienced noticeable gains in muscle mass and strength”

Sam Mounsey

“I have more energy, sleep better and lost more weight

Michael W

“Skip this one, did not do ANYTHING it claims.”


“did not see any improvement after 1 month. waste of money.”


“Had no noticeable effect of any kind. Waste of money.”

Kyan An

Hardly unanimous approval is it?

Where to Buy Testoboost?

Testoboost is available from the official Arazo Nutrition website and also through the Testoboost Amazon page.

Testoboost Review Conclusion

To be honest,

I am disappointed.

As seen in this Testoboost review, the ingredients are not great.

Ok, there is magnesium and the really powerful zinc ingredients included. Both of which can raise T-levels.

But that’s it!

The rest are either unproven or just blood flow and libido enhancers. It’s a rather unimpressive formula.

But credit where it is due:

According to the testimonials, it appears to work for some guys. I have to say – after examining the formulation – I don’t know how, but still that’s what they are indicating.

But then, as many guys, if not more, are saying it is totally ineffective.

The bottom line.

Find yourself a proven testosterone booster that not only contains zinc like Testoboost, but the majority of the other key T-boosting ingredients I mentioned earlier.

That way you will definitely see the results that you deserve!

Testoboost Review FAQ

“How to Take Testoboost?”

Take 3 capsules per day before bedtime, with 8 oz of water.

The Testoboost price is the same on both Amazon and the official website.

One bottle of Testoboost (90 capsules) costs $23.95.

Although a few Testoboost side effects have been reported by users, as a natural supplement it is unlikely to cause health issues.

Some guys say yes, more say no. In my opinion, with just one serious T-booster in the formulation, I struggle to see how it can be truly effective.

“Is There a Money Back Guarantee?”

They do offer a 100% money back guarantee, but it is unclear whether this is for unopened or opened products.

A few guys saw increases in strength after a couple of weeks. More guys experienced no results after months of taking the product.
