Ouch. This SIXSTAR Testosterone Booster review is gonna hurt. But we know what it’s like to suffer the perils of low T-levels. Don’t be fooled by SIXSTAR’s high-end marketing – it’s all in the study of the ingredients and personal experience, which is all detailed right here in our SIXSTAR Testosterone Booster review (decent alternative included).

Some testosterone boosters can seemingly work miracles. I’ve been a big fan of them for several years now and am rarely without a bottle or two in my supplement cupboard. They have helped me to fully optimize my testosterone output, keeping me healthy and well. They are great.

Some are duds, however, without any clinical underpinning and with nothing much to back them up. When I first looked over the ingredients included in SIXSTAR Testosterone Booster, I had a sinking feeling. Was this going to be yet another poor-quality supplement trying to elbow its way into a relatively overpacked market?


Quick Verdict On SIXSTAR Testosterone Booster

Sadly, my gut instinct (and indeed, experience) was correct. SIXSTAR Testosterone Booster is a sub-par testosterone booster wildly outplayed by its competitors. I really wouldn’t bother with it.

The ingredients list is incredibly slim, with no real clinical guarantee of doing much at all. It’s a shame – I hate to see such poor-quality supplements hit the market. And the market is packed with so many high-quality testosterone boosters, like TestoPrime, for example, that there is simply no place for anything less.

If you’re looking for a decent testosterone booster, opt for TestoPrime, Prime Male, or Testogen. I’ve trialed them all and had much better results – most specifically from TestoPrime, where not only did I feel the improvements, but my blood work also proved its efficacy at optimizing my testosterone output. It’s worth the money and commitment. SIXSTAR is not.

What is SIXSTAR Testosterone Booster?

SIXSTAR Testosterone Booster Bottle

SIXSTAR Testosterone Booster is a testosterone booster marketed and sold by a company known as SIXSTAR Supplements.

While the company primarily focuses on pre- and post-workout supplements, such as hydration and protein shakes, as well as creatine products, they also offer SIXSTAR Testosterone Booster as a part of their lineup.

I’ve taken the time and commitment to put SIXSTAR’s ‘T-booster’ through a trial. But as a regular customer, I wouldn’t trouble yourself over it. It’s simply not worth your money, time, or faith.

Thankfully, the current testosterone booster market is in really good shape. There are some truly fantastic options out there, including the likes of TestoPrime, Prime Male, Testogen – any one of these will likely serve you well, as will some others.

I’ve personally used the three I’ve mentioned to fantastic effect (measurably so – I get my bloodwork taken regularly) over the years.

They can really help with various aspects related to optimal testosterone output, boosting output and giving various benefits such as increased strength, improved muscle mass, and enhanced libido… all things that SIXSTAR Testosterone Booster doesn’t manage.

When the ingredients are individually effective and well dosed, the supplement is generally a success. Many top-notch testosterone boosters contain scientifically backed ingredients, such as D-Aspartic Acid, Zinc, Tribulus Terrestris, and Fenugreek, among others. These ingredients have been proven to enhance testosterone levels naturally.

However, SIXSTAR Testosterone Booster’s formulation isn’t so great. In fact, as far as we can tell, it’s rubbish. The ingredients are ineffective and the formula itself is incredibly lean.

None of this is good enough.

What can it do for you?

A good testosterone booster can do lots.

Obviously, its main role will be to help optimize your testosterone output. This is crucial for men’s health. We all begin to lose testosterone after around the age of thirty, at a rate of about 1% year on year.

Testosterone is vital to our health – without good output, we can experience lethargy, lack of drive, atrophy, sexual dysfunction, poor body composition, poor bone density, depression, anxiety, and more.

I’ve been in this position, suffering from some of the above due in part to suboptimal testosterone output. Really, we’re looking at anything around the 25-30 nmol/L mark. Anything above 35 is considered unhealthily high, whilst anything below around 10 will require medical intervention. That gap – around the 10-25 mark – is where a good testosterone booster can come into play.

Unfortunately, that’s where my natural levels were. By using good testosterone boosters, I was able to get it up to the 28-32 mark pretty consistently, as shown by regular blood tests.

SIXSTAR Testosterone Booster won’t do this for you. Its formula has natural yet limited proven ingredients for testosterone production, while effective testosterone boosters include scientifically backed ingredients such as D-Aspartic Acid, zinc, Tribulus Terrestris, and fenugreek.

Another drawback of SIXSTAR Testosterone Booster is that it does not provide much information about potential side effects. Although the product is generally safe and there are no reports of recurring side effects in customer reviews, the lack of information is still concerning. If you have any concerns about potential side effects, you should consult your healthcare provider before using it.

Except… don’t. Just don’t use it. You’ll be better off in every way.

SIXSTAR Testosterone Booster ingredients

SIXSTAR Ingredients and Directions Label

Calcium is an absolutely essential mineral, but at 50 mg per serving, I’m not sure it’s vital here.

To give some perspective, according to the USDA, there’s 299 mg of calcium in a glass of milk. It’s also very unclear what the relationship is between calcium and testosterone, especially in untrained individuals.

Then you get rhodiola rosea, one of the better ingredients in SIXSTAR Testosterone Booster’s formula. You get 386 mg of the stuff, which may bring some benefits.

It’s an adaptogen, meaning that it may help your body to better deal with the negative effects of chronic stress. In turn, there is good evidence that lowering stress and the stress-hormone cortisol can increase total-T.

However, ashwagandha would be a better pick, here. The only rhodiola-testosterone study that’s easily accessible saw a really weak correlation between testosterone increases and rhodiola rosea.

You get 5 mg of sodium with SIXSTAR Testosterone Booster… for some reason. Really, though, it is also an essential component of healthy muscle contraction and relaxation. Its deficiency can also lead to issues like nausea, headache, and vomiting.

However, in this day and age, who is sodium deficient? We mostly eat too much salt, not too little. Also, the recommended daily value of sodium is 2,300 mg per day. 5 mg is nothing.

Ginkgo may have some uses, of course. It has been shown to be able to bolster testosterone in petri dishes. However, this doesn’t translate to human subjects – there is no real proven correlation between ginkgo supplementation and testosterone production. The two most cited studies of Ginkgo on testosterone are generally considered sub-par in the scientific community.

Finally (and note, it’s way too early for me to be saying finally – this list is bafflingly short!), you get 100 mg of boron citrate with each SIXSTAR Testosterone Booster serving. Boron may work as an inhibitor for sex hormone-binding globulin (SHBG), a protein known to diminish testosterone levels by binding itself to free testosterone.

Boron supplementation has been shown to reduce SHBG concentration by up to 9%. The same study that found this (a 2011 study by Reza Naghii et al.) showed a 28% increase in testosterone levels in participants after just a week of supplementation with 10 mg of boron each day.

And there ends our list, premature and underwhelming. It’s too short, missing out plenty that could actually work – where on Earth is zinc, one of the most important minerals needed for optimizing testosterone output? I don’t know what they were thinking when they came up with this list of odd choices and odd dosages. No wonder I didn’t feel the same effects from using it.


TestoPrime Ingredients label

Don’t buy SIXSTAR Testosterone Booster. As we’ve seen and as I experienced, it’s a waste of time and money. And, frankly, it’s just a little bit weird.

There is a lot to choose from on the modern testosterone supplement market. I’ve had good success with a few, over the years, including the ever-fantastic TestoPrime.

It’s made, as are all testosterone boosters, specifically to help men optimize their testosterone levels and improve their overall wellbeing.

With TestoPrime, you will see improvements across several areas when using it, all stemming from improved testosterone output – this includes the likes of improved muscle mass, strength, libido, energy levels, mood, and overall vitality.

Everything that SIXSTAR Testosterone Booster cannot do for you.

TestoPrime boasts a unique yet sensible blend of natural ingredients, all included at clinically effective dosages, all representing a truly comprehensive approach to male health.

These ingredients include the likes of D-Aspartic, panax ginseng, ashwagandha extract, fenugreek, and vitamin D.

D-Aspartic acid has been shown to have a significant impact on testosterone production. It works by stimulating the release of luteinizing hormone (LH), which, in turn, signals the testes to produce more testosterone. Meanwhile, panax ginseng is known for its adaptogenic properties, and has been shown to enhance testosterone levels, reduce stress, improve energy, and support overall wellbeing.

Ashwagandha, one of my personal favorite ingredients, works in a similar way. It has long been associated with stress reduction and increased vitality. As a potent adaptogen, ashwagandha extract can help reduce cortisol levels, which can inhibit testosterone production.

Fenugreek has a long history of use in traditional medicine for its potential benefits in improving libido and supporting healthy testosterone levels, whilst vitamin D is essential for overall health and has been linked to testosterone optimization. It plays a role in regulating testosterone production and maintaining healthy levels of the hormone.

This is far from an exhaustive rundown – TestoPrime’s formula includes a lot more, all of it delivered in using clinically effective dosages. Many products on the market may include these ingredients, but they often use lower dosages that may not deliver the desired results.

TestoPrime ensures potency and effectiveness by providing optimal amounts of each ingredient, backed by scientific research. This attention to dosages ensures that users can experience noticeable improvements in testosterone levels, energy, strength, and overall wellbeing.

Furthermore, TestoPrime takes a holistic approach to male health. It recognizes that testosterone optimization is just one aspect of a man’s wellbeing. The formula includes ingredients that address various other factors related to male health, such as stress reduction, metabolism enhancement, and overall vitality.

I value it very highly. It’s not the only testosterone booster I would recommend; indeed, I’ve had fantastic results with several, including the likes of Testogen and Prime Male. But it is nuts and bolts good – it does everything you want it to do with a high degree of reliability and quality.

With supplements like TestoPrime out there, I have no idea how SIXSTAR could ever expect their ‘T Booster’ to fly.


Please don’t go with SIXSTAR Testosterone Booster. It’s a complete and utter dud.

The formula is kind of nonsensical. It has no unity to it, no drive, no coherence. Most of the ingredients don’t work. Everything is dosed pretty oddly, with either far too little or far too much, despite clear data showing even a casual researcher how much of any given thing should be in there. Goodness knows what the team who came up with it were thinking.

This all looks bad. It looks worse in context, though, because honestly, the modern supplement market is really, really rich in testosterone boosting supplements that do a fantastic job.

I use them a lot myself, with products like TestoPrime, Prime Male, and Testogen making it into my supplement routine on a pretty much constant cycle. Any would do you well, though TestoPrime is perhaps the best for a straightforward, no-nonsense approach. As above, it’s a solid formula, giving you everything you need – well laid out, well dosed, with no boloney.

Buy it, experience it, feel good whilst taking it. Don’t bother with SIXSTAR. They’re almost obnoxiously bad at what they do.
