A lot of our clients ask us for advice on how to boost active free testosterone levels. In some cases, this is to counter the effects of natural aging.

But performance athletes and bodybuilders are the more common types of clients with such requests.

And let me be clear: I’m not talking about some illegal or banned hormone drugs.

Natural testosterone boosters like Six Star are perfectly legitimate products that may help you get more out of your exercise program.

However, a lot of these supplements are not all that effective, so we went and did some research and testing to put together this Six Star Testosterone Booster review.

What Is Six Star Testosterone Booster?

six star testosterone booster product

Six Star Testosterone Booster is a natural dietary supplement that claims to increase the body’s natural testosterone production.

This should not be mistaken for medical hormone treatment.

It’s a way to encourage how your body makes testosterone. Studies have shown that certain ingredients stimulate testosterone production, especially in men.

Six Star delivers a simple pill that claims to be formulated with a precise dosage shown in the next section.

The company claims that this formula has been proven through a human clinical study that lasted 7 weeks.

You should experience strength gains and also enhanced performance levels if you believe the statements on the label.

 

What I would say is that you shouldn’t interpret this as being some sort of magic pill. If your diet isn’t supporting your training routine, and your workouts aren’t designed for gains, then no amount of these pills will help you bulk up.

Six Star is one of the leading supplement companies in America, and we have recommended several of their products in the past.

But we had to get some input from a nutritionist before we could do the same for this one.

Six Star Testosterone Booster Ingredients

ingredients

First of all, let me start by saying that I like that the unique plant-based blend shown on the nutrition label is not hidden behind a proprietary blend.

It’s very common these days and makes our research difficult because we struggle to figure out if they are included in a high enough dose to have any effect.

We asked one of our nutritionist friends to review each of the contents and give us some feedback on whether there are studies to back up the claims.

1 - Boron Citrate

Boron Citrate

The key ingredient in Six Star is boron, which is shown to be a useful trace mineral for regulating sex hormones [1].

Athletes may also be interested to know that boron has been tied to improving bone growth and maintenance, which could become more important as athletes grow older.

But what about the dose of the mineral?

We found one study that looked at the effect of supplementing 6 mg per day in healthy male adults [2]. This study noted a 30% increase in the body’s testosterone production, which sounds promising.

What I would say, though, is that the available amount of boron in SixStar is slightly lower at 5 mg per day, so it may not give you that level of boost.

Testogen, another test booster we reviewed, also has this ingredient.

“A daily dosage of 2.5 to 6 milligrams of boron has been administered in most studies for osteoarthritis and strength conditioning.”

2 - Rhodiola Extract

This is a surprisingly interesting ingredient.

One study did some extensive testing on performance levels in athletes in a double-blind placebo trial [3]. The interesting thing wasn’t a boosted testosterone production within the body.

It seems to have a more important benefit.

The study showed that the peak testosterone to cortisol ratio was leveled in the group that received the supplement.

Why is this ratio important?

An imbalance in this ratio towards cortisol is one of the main factors that might make you feel tired and fatigued.

This may affect both physical and mental endurance, but the ratio after an intense workout is what could end up limiting your training and muscle bulking.

“Rhodiola Rosea is a herb in the Rhodiola genera (Crassulaceae family) which has traditional usage as an anti-fatigue agent and adaptogen compound. Its main chemicals that are thought to be responsible for its effects are rosavin and salidroside.”

3 - Ginkgo Extract

Ginkgo Extract

This is something that you’ll regularly find in health food stores, and apparently, it has been used for centuries for male fertility.

That’s probably why you’ll find a lot of articles about its apparent impact on testosterone production.

But, we did find several reports that made reference to no increased free and total testosterone levels during clinical trials [4].

Those trials also used doses that were ten times stronger than what Six Star is providing, so we’re a bit skeptical about it.

It seems to be included because it’s so common in the herbal community. But we generally prefer seeing some scientific evidence as well.

Let us also just list out the non-active ingredients that make up the pills:

  1. Microcrystalline Cellulose
  2. Dicalcium Phosphate
  3. Stearic Acid
  4. Croscarmellose Sodium Coating
  1. Crospovidone
  2. Silicon Dioxide
  3. Magnesium Stearate

They have no real impact on your body and are just part of the binding material to deliver the active ingredients into your stomach.

Convenient Pills

variety of medicine

The majority of supplements these days come as a powder that you either mix into a shake or add to food.

The advantage is that it is absorbed a lot faster in your stomach. But this isn’t always that convenient.

Timing plays a role in supplements. And you don’t want to try and mix up a shake during your commute or at work.

These Six Star testosterone boosters are provided in a convenient pill form so you could just bring them with you in a bag or backpack.

These Six Star testosterone boosters are provided in a convenient pill form so you could just bring them with you in a bag or backpack.

The recommendation is to take one caplet with a glass of water two times a day. It should be safe to take 7 days a week, and the advice from the manufacturer is to continue using it for one month to allow the effects to build up.

Pros And Cons

six star testosterone booster product

We teamed up with a few clients to test out the claims. There seemed to be a mixed opinion in the online reviews, and with the feedback from our nutritionist, we weren’t too convinced that it might help maintain peak testosterone levels.

During the test phase, we had our clients get their T count measured, and we took a close look at training capacity, endurance, and the impact on muscle mass.

The test results showed a slight increase in T count, but nothing close to what some clinical trials have achieved. It was more at the high end of the normal range for men.

The training results also seemed to suggest that it didn’t end up creating enough testosterone for muscle growth. At least not in a significant way.

Pros
  • The ingredients are generally classed as safe to use
  • Reasonably priced in the bulk order bottle
  • Some reports of improved training performance
Cons
  • Doesn’t contain estrogen blocking ingredients
  • Some users found the pills difficult to swallow
  • Seems to lack more proven ingredients

 

The other negatives were the lack of estrogen blockers. But since it wasn’t overly potent on the T count side, that might not be a real issue.

Also, if you struggle swallowing tablets, then you may need to break these in half as a few people mentioned that they tend to get stuck.

So far, our conclusion wasn’t overly positive.

Side Effects

side effect

The contents of this product are generally classed as safe. That means that they aren’t commonly found to cause allergies or intolerances.

We didn’t encounter any immediate negative effects based on the feedback we got from clients and our own experience.

What I mean is cramps and bloating as soon as the pills hit your stomach.

However, we did find a couple of online reviews where people didn’t seem to react that well over a couple of weeks.

Those side effects could be the result of sudden fluctuations or too many highs and lows.

In some cases, this could result in some acne outbreaks, especially if you’re susceptible to outbreaks anyway.

But we also found that some people got quite irritable and anxious.

If you ever find such negative effects, then make sure you stop taking the pills immediately and possibly talk to your doctor as well.

Where To Buy

Six Star testosterone

We always advise going directly to the manufacturer or Amazon when it comes to ordering any kind of supplements.

There have been too many reports of fake supplements on many different marketplaces. And you don’t want to take pills that could end up doing harm.

Amazon is usually a good place to get the larger bottles of 90 pills, which might be good value when they are on offer.

User Reviews

user review

So our own test results weren’t great. But we understand that this was quite a small test group, and some more research was needed.

To do this, we always look at online user reviews on Amazon and user groups to check if we can find similar results in larger groups.

Here are four review summaries that seem to reflect what a lot of people are saying.

This was one of the reviews where someone seemed to have a negative reaction within ten days. Jason had sudden mood swings and felt constantly irritable even when taking a lower dose.

 

-Jason from Ontario

Jo had positive things to say and had been through several cycles. He did find that his body didn’t trigger the same T count after about five weeks, which is why he took regular breaks.

 

-Jo from Fargo

Steve was also having good results when it came to increased stamina and endurance. He also didn’t think he was as tired and exhausted after a trip to the gym.

 

-Steve from Seattle

Jose had some blood tests done before and after taking the pills for three weeks. When his results came back that it didn’t seem to increase active free testosterone levels, he switched to a different product.

FAQ

How Long Can You Take Six Star Testosterone Booster?

You can take Six Star Testosterone Booster indefinitely if you don’t develop any side effects. However, your body may become used to the ingredients and not respond as effectively. That’s why it’s always good to plan regular off-cycles.

Does Six Star Testosterone Booster Have an Estrogen Blocker?

No, it doesn’t have an estrogen blocker. This may be an issue for some high performance athletes and bodybuilders. There are some other supplements that could solve this problem, but it might be best to get advice from a nutritionist.

How Long Does It Take for Six Star Testosterone Booster to Work?

It takes about a week for Six Star Testosterone Booster to work. Some reports say that an increased T count was measured earlier, but most of these natural supplements are designed to create a gradual boost rather than a sudden spike.

Is Six Star Testosterone Natural?

Yes, Six Star Testosterone is natural, and the herbal ingredients are generally classified as safe. The contents are also plant-based, which would make them suitable for vegans and vegetarians.

Should You Buy Six Star Testosterone Booster?

Our conclusion at the office has been that we won’t be recommending it to our clients, based on our test results and the mixed reviews we’ve read online.

It’s an affordable product, but if you’re looking for results, then it’s generally best to spend a little extra and get a product with a proven track record.

We have seen much better results with a product called TestoFuel. Our professional bodybuilders and athletes have seen measured increases in T count, and the muscle mass impact has looked positive as well.
