Prime Male vs Boost Ultimate

We’re on the hunt for a T booster for the mature market. Our Prime Male vs Boost Ultimate review gives us a look at two popular T boosters that might just be good news for the over 50’s.

As our T levels drop year on year from around the age of 30, it is important to find a supplement that works.

Some are more potent than others and we are putting two of the bigger brands to the sword. Only the best ingredients and dosage will suffice so let’s go through what we’re looking for:

  • More Strength
  • Enhanced Libido
  • Elevated Mood
  • Increased Energy

Of course, safety comes into it combine all this and you have an excellent T booster. Time to get to know the two products in front of us today.

Prime Male vs Boost Ultimate: Who Makes These Testosterone Boosters?

PropuraPrime Male Testosterone Booster Review

Here we have the team behind Prime Male.

They have years of experience to put behind their products and only use 100% natural ingredients.

We like a company to offer a money back guarantee. That’s what we are getting here which is good news for all.

If endorsements are anything to go by, then Prime Male have got it right. The Rocky legend Dolph Lundgren is an advocate. Whether you think he is a legend from the movie or not, the shape he is in these days is impressive.

There are loads of testimonials online of people that have tried Prime Male. There are plenty of before and after profiles out there for a supplement that has a loyal following.

Boost Ultimateboost-ultimate-review

The company uses the same name as the product for this US-based setup.

We like that they have 24/7 support. Although they say this is via email – how quickly they respond is the question. They also have a money back guarantee so a thumbs up for both in that respect.

A confusing statement is that they say using this product gives permanent results! Surely this is only the case for continued use?

Their aim seems to be increasing blood flow. This is good for sexual health but also good for the muscle as well.

They say this product gives you the following:

  • Testosterone
  • Energy
  • Desire
  • Workout Stamina

They have gained a fair bit of media coverage with Maxim and ebay two of their selected badges displayed on their site.

Time to see what goes into each product.

Prime Male vs Boost Ultimate Ingredients

This is how we will really separate the two products.

It’s a good start for Prime Male – no proprietary blends. The same can’t be said for Boost Ultimate though. Their blend means we cannot see all the dosages. How effective will each ingredient be? We will get what information we can.

Mutual Ingredients


A good start to proceedings.

Although this isn’t the flagship ingredient of either product it is still one we like to see.

A traditional and natural option, Ginseng is a wise choice when it comes to stress relief.

We all know stress is a killer of our T levels so anything that can bring this down is always going to be useful. Ginseng has other uses too – it is also good for reducing prolactin levels.

Studies have shown that high prolactin often equals low testosterone.

Boost Ultimate managed to keep this out of the proprietary blend, their dosage of 125 mg and Prime Males 120 mg makes it an even start.


This ingredient is becoming more popular in T boosters for a reason.

Nettle is a useful aromatase inhibitor that stops your body from turning testosterone into estrogen. This becomes more of a problem the older you get so you want plenty of ingredients that offer this.

It stops the Sex Hormone Binding Globulin from being as effective. This means your testosterone is not bound and therefore useless. As a result, it can be used in the body.

It is the beta-sitosterol in Stinging Nettle that is thought to help boost testosterone levels.

Prime Male have gone for an optimal 160 mg of this ingredient. The problem for Boost Ultimate is that they have included it in their proprietary blend.


A very effective mineral that boosts the benefits of other ingredients including the likes of Magnesium (which is only found in Prime Male of our two products today).

The final mutual ingredient and it is another that inhibits SHBG – like we said, more of these ingredients is fine by us. shows us how much free testosterone Boron can provide. Boron = more free T.

It is a good ingredient for the over 50’s as it is thought to be used for prostate health. Studies are still ongoing for this but it could be an added benefit.

An ingredient that also helps to build muscle. It’s not surprising Prime Male have dedicated 5 mg of space to it.

We have no idea how much Boost Ultimate have gone for as it is part of their proprietary blend once again.

Individual Ingredients

Prime Male

Vitamin D3

The sunshine vitamin is one of the best going.

It is thought that low levels of D3 are linked to low testosterone. This being the case, it is important to keep it topped up, a T booster being an excellent source if the other ingredients are beneficial.

Our bodies actually create their own D3 when our skin is exposed to direct sunlight. The problem is, many of us in the western world are deficient. Clearly, we aren’t getting the sunshine we need.

An ingredient as significant as this gets the dosage it deserves. 5,000 IU being a big an optimal amount from Prime Male.

Vitamin K2

A smart inclusion.

What taking extra D3 you want to combine it with K2 to prevent the calcification of arteries.

On top of this, advises that taking the two together increases the effects of each.

Also, K2 is the version of the K Vitamin that is absorbed the fastest.

45 mcg is a good amount.

Vitamin B6

We want more ingredients that stimulate androgen receptors, that’s just what we get here.

This encourages your testes to create and then release more T.

Studies have also shown that it is good at reducing the level of estrogen you have in your body. And yes, it is another ingredient that stops SHBG from being as effective.

It has even been found to be good at reducing the levels of estrogen in the body.

A good ingredient for many reasons and one that will free up more testosterone. The dosage of 7.5 mg is another optimal one.


We mentioned that Prime Male has included this, and you will be glad that they did.

Magnesium is good for inhibiting SHBG, Prime Male are really trying to free up your testosterone.

It has been shown that men with more magnesium in their blood, usually have higher levels of free T (see The Journal of Pharmaceutical and Biomedical Analysis).

Another proven ingredient backed by studies and human trials. This is what you want to see.


About as good as it gets, it might be the best ingredient in the whole Prime Male vs Boost Ultimate review.

Zinc is so important here, our bodies cannot create more testosterone without it. It even stimulates the luteinizing hormone. This communicates with the testes to create and release more T. Yes, another ingredient that has this great trait.

Zinc even stops our bodies from depleting T so quickly during an intense workout. Saving more for later.

The dosage of 30 mg is a great amount.

D-Aspartic Acid

A very good inclusion from Prime Male, this is one of the excellent ingredients we have come to expect in the better supplements.

It increases the amount of the Human Growth Hormone there is in your body but also acts fast. There are studies that have shown DAA to increase testosterone levels by 50% in under 2 weeks!

Another ingredient that stimulates the luteinizing hormone it also ensures you put the protein in your body to good use. That’s right, using them for gains.

The 1,600 mg is another optimal dosage.


Another very effective T booster.

Luteolin is found in Citrus fruits and lowers estrogen. It actually encourages your body to create more androgen, this means more T!

An effective ingredient is given 60 mg in Prime Male.

Mucuna Pruriens

Lowering prolactin and estrogen, Mucuna Pruriens is a very effective ingredient. discusses how it works against prolactins suppressive effect on libido and testosterone.

This is what we want to see and a good inclusion in our Prime Male vs Boost Ultimate.

For the mature male, the libido enhancing attribute will also be beneficial. At 300 mg, you are getting a good amount once again.


An ingredient that does not directly boost your T.

Nonetheless an effective one. This is because it actually enhances the good attributes of the other ingredients. Since Prime Male is full of proven T boosters, this is a clever inclusion.

10 mg is all you need for a boost.

Boost Ultimate

Tongkat Ali

Sometimes known as Longjack it is thought to be an effective libido enhancer.

According to it is an aphrodisiac and there is a lot of evidence to support this. It actually says there is a lack of evidence in terms of testosterone boosting but might be an effective anti-estrogen ingredient.

Sexual health is important so it is a good ingredient for a T booster. It might even help with sperm production. There is further evidence needed for this though.

It might even be able to help battle stress but again, this requires more research.

200 mg is thought to be the minimum you need. Since we are getting 400 mg in Boost Ultimate, they have got it right.


We’re a fan of the traditional ingredients and this is another.

It has similar attributes to Tongkat Ali in that it is another ingredient through to be an aphrodisiac. It could also be good for stamina.

Another possibility is that it is anti-inflammatory when it comes to stress. This is good for battling the after-effects of stress, but not stress itself.

You need a big amount for the benefits to be really felt. Anything above 1,500 mg really. We are only getting 250 mg in Boost Ultimate so it is severely underdosed.


This is an amino acid.

It is a good idea and for the mature market it becomes more important the older we get.

Many believe it is good for delivering your T. Enhanced blood flow helps to get testosterone around your system.

This is good for muscle building and it is even good for protein synthesis.

An effective choice for making muscle as well as sexual health.

It is thought that 3,000 – 6,000 mg is the required amount. Boost Ultimate is only providing 250 mg so another underdosed ingredient.

Boost Ultimate Proprietary Blend

The remaining ingredients are all part of the 745 mg proprietary blend in Boost Ultimate.


Mostly used for medicinal purposes but also as a flavoring agent in soft drinks and many foods.

WebMD advises that some supplements out there claim that chemicals (sterols) in this ingredient can be converted to anabolic steroids like testosterone. However, this is actually a false claim.

A bad ingredient to include that has no apparent use and also part of the proprietary blend.

Pumpkin Seed Powder

A variant of Cucurbita Pepo most of what you read about it seems to show it is used for prostate disorders.

Could be worse though, it is a source of Vitamin B6. You have already read about the benefits of this ingredient including its use for stimulating androgen receptors. Getting your testes to create more T is what we need.

Still, as it is in the proprietary blend, we have no way of telling if the dosage is optimal or not.

Muira Puama

Hard to get excited about ingredients that are unproven.

It is derived from the wood and root of its plant. It might be an aphrodisiac and is usually used for treating erectile dysfunction. However, WebMD says the chemicals in this ingredient have no known effects on the body.

They go on to say that there is insufficient evidence to back its claims of being useful for sexual disorders.

Most likely a waste of space.

Oat Straw

An ingredient most commonly found in a nootropic.

Oat Straw is thought to benefit cognition. Yes, this is great for mental performance but that’s not what we are after here.

To be honest, there isn’t a lot of evidence to show it is effective although it might be good for working against the effects of stress.

Some sources say it is an aphrodisiac that’s probably why they have included it but again, it’s unproven.

Anything unproven is no good to use and we’re seeing too many from this supplement. The Prime Male vs Boost Ultimate as a whole could do without them. Going by the total blend amount, the dosage is no use either.

Cayenne Pepper

Another ingredient that is a bit out of place.

A lot of fat burners include this as it is an effective appetite suppressant.

It is thought to also be good for blood flow. This will particularly help anyone with erectile dysfunction so we can see why it has been included.

There is some loose backing for it being an aphrodisiac but we don’t believe this to be true.

Either way, with no dosage it is hard to see if it will have any benefit.

Astragalus say that in terms of muscle protein synthesis and testosterone,  it is an unexplored ingredient. This means that there aren’t enough studies to get behind it.

The same page also says that many of the studies have been conducted when Astragalus has been injected into the subject. Oral consumption needs more study,

As of yet, no one has studied it to see if it effective for testosterone boosting. That says all we need to know.

Catuaba Bark Powder

Catuaba Bark Powder is thought to show promise for protecting the brain cells in animal trials. According to WebMD it is often used to heighten sexual arousal as well as treat sexual performance problems. However, there is insufficient evidence to support this.

We are seeing a constant theme of unproven and understudied ingredients. This brings the legitimacy of the supplement as a whole into question.

Hopefully, we will see more ingredients with human trials coming up.


A very popular tret and one that has been used for its numerous health benefits for ages.

There is a problem though. It has been found to be detrimental to testosterone levels. This is by some studies that have shown it to have the potential to increase cortisol levels.

Stress is all around bad news for your T. Anything that increases its effects is a bad ingredient.

It could even interrupt testosterone synthesis.

The glycyrrhizin in Licorice is what makes it have the negative effects.

Tribulus Terrestris

Once heralded as the next big T booster, studies since have not been kind.

Still widely found in testosterone boosters as it has been shown to be an effective libido enhancer. says it has been shown to be a good libido enhancer. However, the same resource comments on its limited use for power output and testosterone enhancement (which it has repeatedly failed to do).

More libido enhancing, but not a lot else.


Ok, Orchic Substance is made from Cattle testicles.

WebMD says that whilst marketers imply that orchic extracts are a good source of testosterone, there is currently no actual evidence to support this claim.

Strange then that this would be included. With no proven use and no dosage, it is another pointless ingredient, only a little gross as well.

Oyster Extract

Finally, another decent ingredient.

We like Oyster Extract as it is high in Zinc.

Like we mentioned earlier, Zinc is vital for increasing T.

You need to know how much you’re getting so you can see if you are going to get an effective amount of Zinc. With it being in the proprietary blend, we have no way of telling.

Prime Male vs Boost Ultimate Side Effects

The good news is that neither product contains anything to be concerned about.

In Boost Ultimate, the proprietary blend would usually be a worry. Since the ingredients seem fine and the dosages can’t be that high, it is more likely that everything is underdosed anyway.

As always, if you have allergies, check the label.
