TestoFuel vs P6 Black: Who Makes These Testosterone Boosters?

Roar AmbitionTestoFuel Review

These are the guys behind TestoFuel and they have one of the better reputations and for good reason.

Whilst they are not the only company in the world to offer a money back guarantee, they have many other positive attributes going for them. They also review and update their products regularly ensuring that the customer is getting the best quality version with the most up to date dosages and ingredients.

If that wasn’t enough they also have some excellent celebrity endorsements. None other than former Mr. Universe Robby Robinson uses TestoFuel – check the guy out he’s in his 70’s!!

On top of that, Roar Ambition’s fat burner Instant Knockout is used and endorsed by UFC fighter Diego Sanchez as he and other fighters used in when making weight.

Their products are all made from 100% natural ingredients so they are a safe bet when it comes to supplements.


The people that make P6 Black are Cellucor and they seem to enjoy trying their hand at innovative supplements.

This T booster, for example, has the bonus of offering a nootropic element, an interesting combination and we will dig deeper to see if it works.

They have a vast range of products that include everything from their own merchandise and clothing to pre-workouts and weight loss supplements.

Their slogan shows they have thought their marketing strategy through and the ‘better is never enough’ that you see on their site is something we like the sound of.

They have their own sponsors including the athlete Craig Capurso amongst others.

Again they have a 100% satisfaction guarantee so another company that is confident enough in their own product to back it.

TestoFuel vs P6 Black Ingredients

This is where it gets interesting and today is even more so. Because there are a lot of the same ingredient on show from both companies, looks like optimal dosages might decide this one.

This is arguably the most important part – even if you have an impressive ingredient profile, it is still only as good as the amount of each one you use.

The problem we have here is P6 black does have some of its ingredients as part of proprietary blends. This means we cannot see what the dosages are of some of the ingredients, instead, the overall blend dosage is given. This makes it difficult to see just how effective an ingredient is and is something we don’t like to see form a supplement.

Let’s take a closer look then at what goes into these products.

TestoFuel vs P6 Black Mutual Ingredients

Vitamin D3

Yot boosters, best testosterone ingredients, vitamin d3ur body is capable of producing this hormone itself but deficiencies in the modern body mean it is necessary to supplement.

You produce it by exposing your skin to the suns rays, this is when your body turns the rays into D3 – the deficiency is because we are not getting enough sun!

This is especially a shame since the benefits to T levels are great for your free testosterone, as well as your energy levels.

How about the optimal dosage then? Many studies point to around the 3300IU mark is a good amount and TestoFuel contains a giant 5,000 IU. With P6 Black having 3332IU it is also an optimal dosage so this is a close start.


Testosterone cannot function without this important mineral. It is even good for you workout as it prevents your body from depleting the level of testosterone in your body whilst training and can reduce prolactin levels.

A word of caution though – although most people are deficient in it, you don’t want to supplement too much of it. Zinc is found in a lot of foods such as red meat and dairy and the 10 mg in TestoFuel is a sensible boost. Also bear in mind they include Oyster Extract which is high in Zinc. The 30 mg in P6 Black therefore makes this an even one.

D-Aspartic Acid

Great for those big muscle gains in the gym this is a top ingredient for any testosterone booster. It tells the tests to produce and release more testosterone by stimulating the luteinizing hormone.

Anything between 2-3,000 is about right in terms of optimal dosages. The 2,300 in TestoFuel makes for good reading and it is another top T booster ingredient dosed correctly.

We cannot say the same for P6 Black since their DAA is included in a proprietary blend. Because the blend is a total of 2,105 mg and includes multiple ingredients, we think it is safe to say it is not optimally dosed.

As a result, TestoFuel pulls away even further.

TestoFuel vs P6 Black Individual Ingredients


Asian Red Panax Ginseng

There are many studies to back up the T boosting qualities of this ingredient. It even has benefits for your libido and focus so it could be considered to be TestoFuels own Nootropic enhancer.


It is more and more obvious that TestoFuel is an extremely well-researched supplement as this is another great testosterone boosting ingredient.

Also a great libido enhancer, this herb is another ingredient that can boost the release of the luteinizing hormone.

P6 Black


This is often referred to as dehydroepiandrosterone but we prefer it when people just call it DHEA!

It doesn’t exactly have completely positive backing, there are some studies to show it can boost your testosterone, but at the same time is banned from being used within many athletic organizations such as the NCAA.

Alpha GPC

Found in the nootropic section on the label, it is thought to slow down the cognitive decline that usually occurs in your later years it is also thought to aid the performance of athletes.

Since it is part of the blend, we have no idea what the dosage is.

TestoFuel vs P6 Black Side Effects

Well, the good news for one of our testosterone boosters here is that their product is made from 100% natural ingredients that are all optimally dosed, that’s TestoFuel.

Roar Ambition seem to make it their mission to create proven supplements that are safe for use.

Whilst, for the most part, P6 Black is a safe T booster, the Zinc is what worries us a little. If you have too much Zinc in your diet you run the risk of the side effects which can be nausea, diarrhea, itching, headaches and more.

The proprietary blend is another concern, there are other ingredients within the blend that could be dosed high and therefore could come with their own side effects.

TestoFuel vs P6 Black Conclusion

Winner: TestoFuel

Testosterone Booster - TestoFuel box bottle

Well it looked like it could be close in the beginning and although they had some pretty similar ingredients, there was only one product here that included optimal dosages and other great ingredients as well and that’s TestoFuel.

The blend of great dosages and the natural ingredients make it the ultimate T booster in our opinion. Having tested and reviewed 100s of supplements this is amongst the best testosterone boosters around.

P6 Black was up against it when we saw the proprietary blends. The fact that they also include an ingredient banned by some athletic committees makes it a supplement that we find hard to back despite the fact they had some great ingredients, above all it must be safe.

That’s another reason we like TestoFuel, they stay away from blends and make the user able to see exactly how much of each of their ingredients are in each serving. Roar Ambition get it right every time, as their other credible supplements make clear.
