TestoFuel vs Weider Prime Testosterone Support

A battle of two popular T boosters, but which of our TestoFuel vs Weider Prime Testosterone Support supplements deserves their following?

Weider Prime have built theirs from what appears to be mostly Amazon sales. TestoFuel has a lot of online testimonials to support their cause.

Either way, we will soon find out if either has been getting away with an inferior product and relying on their packaging and marketing or if they are the real deal.

We are looking for the following:

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

Anything less than this won’t do. As the latin goes Nil Satis Nisi Optimum ”Nothing but the best is good enough”.  Words to chose your T booster by.

Firstly, let’s get to know the teams behind the products a little.

TestoFuel vs Weider Prime Testosterone Support: Who Makes These T Boosters?

Roar AmbitionTestoFuel Review

Here we have the UK based company behind TestoFuel.

They ship directly from both the UK and the USA and there are a ton of positive before and after profiles being posted all the time.

People seem to be happy with the results. Roar Ambition also has a generous money back guarantee. Customer service doesn’t end there. They also check and amend their ingredients and dosages regularly. This ensures the customer is getting the best version possible.

Making their products to FDA and GMP regulations they have some quality endorsements.

Former Mr. Universe Robby Robinson puts his name to TestoFuel. The guy is in his 70’s and in unbelievable shape!

They also make a fat burner called Instant Knockout. This is endorsed by UFC fighter Diego Sanchez who uses it to make weight before a bout.

Weider Primeweider-prime

This is the US-based company behind our second product.

Their website is pretty vague, to be honest. It seems to be a sales page for this product and we cannot see that they offer anything else.

This is typical of products that often do well on Amazon! It seems as though it is named after the founder of Mr. Olympia, Joe Weider. We can’t confirm if this is true and their site doesn’t really go into it.

There is a bit of a Weider Prime Testosterone Support bodybuilding scene so we will find out if this is deserved or not.

The site does say there is a money back guarantee, but it doesn’t provide details.

They do say this product helps with:

  • Support Healthy T levels
  • Improved Cardiovascular Performance
  • Improved Lean Body Mass

Time to see if the ingredients back this up.

TestoFuel vs Weider Prime Testosterone Support Ingredients

The good news is that neither product uses proprietary blends. This means all the dosages are revealed.

The suggested serving is definitely better with TestoFuel. They advise taking 1 capsule 3-4 times a day. This will really spread out the T boosting benefits to ensure you are constantly topped up.

In comparison to this, Weider Prime advise taking 2 capsules a day.

Let’s see what they have for us.

Mutual Ingredients

Vitamin D3

They have both started with what we believe to be among the best T booster ingredients going.

Low levels of D3 are often linked to low testosterone so keeping it topped up is important. Our bodies actually create their own when our skin is exposed to direct sunlight.

The problem is, we obviously aren’t getting enough sun as so many of us are deficient. This makes supplementing D3 all the more important.

TestoFuel have given us a massive and optimal 5,000 IU. This will really get your T on the rise.

Weider Prime have only included 400 IU. This is a tiny amount considering the lower optimal dosage is over 3,000 IU!

Vitamin B6

Another excellent inclusion.

B6 is good for stimulating androgen receptors.

You need plenty of ingredients that inhibit the Sex Hormone Binding Globulin. Here is just one of many good ones. This means it stops your body from binding your T and making it unavailable for use. Freeing up T so it can thrive and get to work in the body.

It can even support your immune system and help your body to break down proteins.

We cannot store B6 so keeping it topped up is important.

The dosages of 5 mg in TestoFuel and 10 mg in Weider Prime will have a similar effect.


Another top ingredient.

Zinc is one of the most important T boosters because our bodies cannot create more testosterone without it.

It stimulates the luteinizing hormone. This communicates with the testes to create and release more testosterone. Not done there, Zinc is also good for ensuring our bodies do not deplete T levels so much during an intense workout.

Such a good ingredient gets the dosage it deserves form both. The 15 mg in Weider Prime is an optimal amount. As is the 10 mg in TestoFuel, this is especially the case because they also include Oyster Extract. This is high in Zinc, making the levels in TestoFuel optimal.

Individual Ingredients


Vitamin K2

A sensible and useful idea when supplementing Vitamin D3.

This is because K2 stops the possible calcification of the arteries when taking Vitamin D3. It is also useful as Examine.com advise taking both together actually increases the effects of each.

This is a good trait and shows that TestoFuel has been well thought out. The dosage of 180 mcg will give you the above effect.


Once again, top T booster.

Another that inhibits the SHBG (we mentioned you want more of these!).

According to The Journal of Pharmaceutical and Biomedical Analysis, men with more magnesium in their blood tend to have higher levels of free T.

A good ingredient then. Magnesium also helps the body cope with the effects of oxidative stress. This is caused by exercise and aging.

For you to really get any benefit, you will need at least 100 mg. Testofuel is giving us 200 mg which is another optimal amount.

D-Aspartic Acid

Good for increasing the level of the Human Growth Hormone.

Also, it is a proven fast-acting T booster. Those words should be music to your ears. One study showed that DAA increased T levels by 50% in under 2 weeks!

Another ingredient that will stimulate the luteinizing hormone. So far, TestoFuel have proven they will get your T on the rise!

The dosage of 2,300 mg is a great amount.

Siberian Ginseng

A traditional ingredient that we like. Anything natural that can help you to cope with stress is always going to be good news for T.

We’re not a fan of studies that aren’t on humans but there is a study that shows how rats with 5% Panax Ginseng in their diet for 60 days have shown significantly increased blood testosterone levels.

This has some potential as well as being a proven T booster. It will also enhance your libido. This is an important trait for this type of product.

It has also been shown to keep prolactin levels down. Since people with higher prolactin often have lower T levels, this is a good thing.

The 100 mg is another excellent boost.

Oyster Extract

Having touched on this earlier, you already know that it is important because of its Zinc content.

On top of this, it has multiple trace elements that have various benefits for the body.

Weider Prime Testosterone Support

Vitamin B12

It is mostly found in nootropic supplements and pre-workouts but it can help with sperm production so the sexual aid side of it means it’s not a terrible inclusion.

There isn’t a lot of notable research for it though and the ingredient itself isn’t known as being reliable.

It is helpful for influencing how we use food for energy. This is why it is often in pre-workouts and why Weider Prime promised more energy probably.

However, in terms of boosting T, it’s not the best. The lack of studies makes it a difficult ingredient to find an optimal dosage for. Most supplements tend to include similar dosages to the 120 mcg we have in Weider Prime.


A very important nutrient for the body but why has it been included here?

There is a study that suggests that calcium can be useful. When tested on a group that supplemented it compared to a group that did not whilst taking part in resistance training, the free testosterone levels of those that did supplement calcium rose.

There are some that suggest it could support muscle growth.

You get it from many different foods and it’s not the greatest ingredient for a T booster. The 35 mg should be a bit of a top up.


Exmaine.com advise that this is an essential mineral, it is described as being used for insulin sensitivity.

This is good for your T which is affected when insulin levels fluctuate. Examine do go on to say that supplementing more chromium than the body needs does not produce reliable results.

It has been linked to weight loss and is found in a variety of foods including meats, whole grain foods, and vegetables.

We’re not convinced though.


Mostly found in Broccoli, this is an ingredient that comes with a bit of controversy.

You will see it included because it can reduce estrogen levels and is an aromatase inhibitor. Anything that stops your T from being converted into estrogen is good, right?

Well, there are many studies that show it can actually increase estrogen levels. Obviously, this is the opposite of what we want. As the studies are still conflicted and uncertain, we advise you stay clear of it until there is more concrete support.

The 50 mg dosage appears to be a standard dosage for supplementation.

Ashwagandha Extract

Another ingredient good for helping your body deal with the effects of stress.

It is another found in nootropics for the same reason.

It has also been shown to help with sperm support.

Let’s look at what it might also be good for – although might is like a dirty word at CLM!

It might be useful for increasing muscle strength. Sure, the potential for your gains but we want the facts of course.

It could also be good for reducing inflammation which will aid cardiovascular health. Some are even researching it as an athletic support.

After all this, it doesn’t actually increase T levels though. At 675 mg it is taking up a lot of room for an ingredient that won’t raise your T levels.

Cordyceps Extract

A fungus that really needs further studies to back it up.

However, it might help with reducing the effects of oxidative stress again. Never a bad thing and the anti-aging properties would be good if there was more evidence to support this.

It could even be a libido enhancer. The thing is, there are a lot of proven aphrodisiacs on the market so the space would be better spent on one of those.

Another ingredient that won’t reliably get your T on the rise.

Since the recommended dosages start at around 1,000 mg, the 390 mg here will not do very much anyway.


An ingredient you will often see in supplements.

It brings out the best in the other ingredients, enhancing their capabilities.

This is only good if the other ingredients are good. Since Weider Prime is a mixed bag, the results of Piperine will be the same. Derived from black pepper, it is a decent ingredient.

TestoFuel vs Weider Prime Testosterone Support Side Effects

The good news is that there does not appear to be anything too surprising in this product that would concern us.

The dosages and ingredients in TestoFuel are all natural and optimal. Obviously if DIM was to increase your estrogen levels you wouldn’t be happy with Weider Prime but it should be ok going by the dosage.

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

(Clean Lean Machine tip: Take advantage of their free 1 month supply when you order 3 boxes whilst the offer is still available!)

There was only one impressive T booster of the two and that is TestoFuel.

It has all the ingredients you want in a T booster, and at optimal dosages. This makes it among the most effective we have seen. If you want more T, TestoFuel is the product you’re looking for.

What really stood out is how poor a product can be and still sell well on Amazon.

Thankfully for you, we are here to tear apart the weak products that rely on their packaging and marketing.

Proven T boosters are what we are interested in.

Weider Prime was a let down because it severely underdosed Vitamin D3, and included too many unproven ingredients.

It was good that it had a couple of good T boosters, but there was too much filler.

To wrap up our TestoFuel vs Weider Prime Testosterone Support review, the better product always stands out in the end. This time, it was TestoFuel.
