In this Six Star Testosterone booster review we are going to examine the ingredients in this product which comes from the huge company MuscleTech.


You are going to learn if Six Star testosterone booster is worth buying, if the ingredients are good and if it comes with any side effects.

Let’s get started:

Six Star Testosterone Booster Review

I want to kick off this Six Star Testosterone Booster review with a swift outline of this product.

Six Star is an offshoot of the supplement company, MuscleTech.

Chances are, you already know this firm. They make a fair amount of decent bodybuilding nutrition products.

Let me make this clear.

This is not a ‘here today, gone tomorrow’ company. 

These guys have pedigree in the supplements market, so for a start you know you are not going to be totally ripped off.

But, past glories do not mean every supplement is going to be amazing!

Six Star Testosterone Booster is designed with the serious bodybuilder in mind. They claim that this testosterone booster will:

  • Increase testosterone levels within 7 days
  • Improve testosterone to cortisol ratio
  • Enhance training
  • Boost athletic performance
  • Build muscle and drop fat
  • Improve libido
  • Raise muscle tone

How Does Six Star Testosterone Booster Work?

These are the biological processes behind the supplement, according to Six Star themselves.

Boosts Active (Free) Testosterone

Get this fact:

Most of the testosterone in your body is currently unusable.

Let me explain.

About 2% of your total testosterone is available, or ‘free’. It’s sitting there ready to build muscle, increase libido and improve strength.1

The rest?

Around 60% is tied to sex hormone binding globulin (SHBG) and the remainder handcuffed to albumin.

The 60% tied to SHBG is generally kept under lock and key and cannot be utilized by the body.

Six Star Testosterone Booster promises to release this bound testosterone. Raised levels of testosterone mean:

  • Improved muscle protein synthesis – your muscles will rebuild faster and stronger 2
  • Increased libido – as testosterone increases, your desire to hit the bedroom raises too 3
  • Improved nitric oxide production – nitric oxide opens up the blood vessels. This means more oxygen and nutrients reach the muscles. Not only does this help the muscles build, but the increased oxygen improves stamina and reduces lethargy 4 5

Improves Testosterone to Cortisol Ratio

Six Star claim that their testosterone booster ensures cortisol does not become the boss!

Let me explain why this is important.

Cortisol is the hormone which is released when we are under stress. It is the enemy of the bodybuilder.

This hormone has been proven to reduce testosterone levels. Hence it is important to ensure testosterone is always in control in the testosterone/cortisol ratio.6

If cortisol takes hold, it can push the body into a catabolic state.

Which means:

The muscles you worked so hard to build will begin to break down! 7

In summary:

Six Star Testosterone Booster aims to raise T-levels and keep cortisol in check.

Let’s see what the formulation contains to achieve these claims.

Six Star Testosterone Booster Ingredients

Broscience Six Star Testosterone Booster Review ingredients

Something I noticed straight away:

This product only has 4 ingredients. That is a very low count for any testosterone booster. But, if they are all powerful and proven T-boosters, it could still be a winning formula.

Here we go with the detail:


It’s no surprise what I am going to begin with!

Calcium is essential for strong bones. If you are seriously into lifting the heavy iron, you don’t want those arms giving way! 8

There has been some research that calcium can improve testosterone production in rats. In humans, there is little evidence that it has any effect.9

But get this:

Some studies have shown that calcium supplementation can increase levels of cortisol. This is the exact opposite of what Six Star Testosterone Booster aims to achieve!

And a final fact.

Nothing to do with T-boosters, but I think it’s interesting. Calcium is the most abundant metal in the human body! Amaze your friends with that one over a couple of cold ones!


Broscience Six Star Testosterone Booster Review rhodiola

A herb which has been proven to increase endurance. By improving oxygen uptake, it enables more O2 to be utilized by the muscles and improve stamina.10

But a couple of provisos to take into account:

  • The guys showing improved endurance in this trial consumed 1080 mg per day – Six Star Testosterone Booster contains 386 mg
  • The study also checked cortisol/testosterone ratios and reported no improvement at all

Ginkgo Biloba

Popular in Chinese medicine, this herb has been shown to improve blood circulation.11

In doing so, it could improve energy and stamina and also lead to some impressive erections.

Although some bad news:

Studies show that, despite traditional claims, this herb has no effect on testosterone levels.12

Boron Citrate

When researching for this Six Star Testosterone Booster review, one thing stood out.

The marketing makes a great deal of its ‘massive 100 mg Boron Citrate’ ingredient.

Let me put this into perspective:

Be careful when checking ingredients for boron. It is the ‘active boron’ level you should be looking for, in this case, 5mg. That’s the element that will make this difference.

Anyway, some good news!

Finally in this supplement, a real T-booster! Boron has been scientifically proven to raise free levels of testosterone in the human body!

It is a genuine ingredient that should be in any testosterone booster you buy! 13

Six Star Testosterone Booster Ingredients Breakdown

Broscience Six Star Testosterone Booster Review mix

When looking at the ingredients in this Six Star Testosterone Booster review, we really need to ask one simple question:

Do the ingredients stack up to a powerful T-boosting formula?

To make this easier, I have compiled a checklist below. These are the ingredients that you should look for in a really serious testosterone booster.

I have indicated how Six Star Testosterone Booster performs:

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

With just one tried and tested testosterone booster in the formulation, it’s a rather weak supplement.

Six Star Testosterone Booster Side Effects

Broscience Six Star Testosterone Booster Review side effects

I searched testimonials, including forums and the Six Star Testosterone Booster reddit, to see if I could locate any side effects.

To be honest, there were few reported. Although I did find some complaints of guys suffering from:

  • Migraine
  • Upset stomach
  • Diarrhea
  • Insomnia

In general terms, as it is a 100% natural product, there are no reasons to believe it would have any serious health implications.

In short, the Six Star Testosterone Booster Elite Series side effects are negligible.

Six Star Testosterone Booster Review Conclusion

Broscience Six Star Testosterone Booster Review not approved

If you recall the beginning of this Six Star Testosterone Booster review, I said we would investigate whether this was a keeper or to be resigned to the trash can.

Well, trash is probably too harsh.

I’ll tell you why.

This T-booster does contain Boron, a proven and effective testosterone boosting ingredient. That’s great to see.

There’s more.

Six Star, for a theoretical testosterone booster, is cheap.

But, they are the only Six Star Testosterone Booster benefits.

Listen to this:

I wouldn’t call Six Star a real testosterone booster. It’s basically a boron supplement. The other ingredients have little to no effect on testosterone at all. And I could see no evidence of any cortisol reducing effects.

You can buy boron supplements cheaper than Six Star.

Here’s the bottom line.

There are some powerful T-boosters on the market, with the same 5 mg boron level as Six Star Testosterone Booster. But, they are also packed full of other proven T-boosting ingredients!

Even if you bought Six Star testosterone booster, for real results you would need to take other supplements in addition!

That’s complicated and expensive!

My advice:

Look for a testosterone booster which contains the powerful ingredients I listed above, and you will reap those rewards fast!
