About The Product

P6 Extreme Pump is Cellucors testosterone booster, released in 2017. It comes in 30 serving containers, with a serving size of 5 capsules per day - this is good, as itll keep your body topped up with key ingredients needed to boost test levels.

However, were unsure why Cellucor has tried to create a testosterone booster that delivers enhanced muscle pumps instead. This is a benefit that pre-workout supplements can deliver - so we prefer test boosters to contain more ingredients shown to raise your T levels.

After all, why else are you buying a testosterone booster for? Anyway, well tell you a bit about the company behind P6 Extreme Pump - for those that dont know.

Who are Cellucor?

Cellucor is a sports nutrition company thats owned by Nutrabolt, which is based in Texas (USA). This brand was created in 2002 and has since become a popular for many supplements - especially their whey protein series.

But were here to review their addition to the testosterone booster series - P6 Extreme Pump. So lets see what its all about below.

P6 Extreme Pump Ingredients Explained

As weve mentioned, we dont like that P6 Extreme Pumps ingredients have all been hidden inside a proprietary blend; this means youre not shown the exact dosage of each ingredient inside this testosterone booster (well expand on this below).


Proprietary blends are mixtures of numerous ingredients thatre only shown to you as 1 quantity. As you can see from the P6 Testosterone and Pump Blend on its ingredient list, the overall amount is 3,175mg - but youre not shown the dosages of each ingredient inside such as Diindolymethane.

This increases your risk of side effects, and also makes it uncertain whether this pre-workout will work. For this reason, we try to avoid any supplement that contains proprietary blends.

Not only that, we can see that Cellucor has left out most of the key test boosting ingredients shown to work. We prefer ingredients that are tried-and-tested, so this isnt a good thing for us.

But there are some positives; P6 Extreme Pump contains one key ingredient thats proven to work - Fenugreek.

Anyway, well take you through each ingredient inside this test booster - so you can see how effective it really is for yourself.

Heres Everything You Need To Know:


P6 Testosterone and Pump Blend (3,175mg)

As weve mentioned, this is the proprietary blend inside Cellucors P6 Extreme Pump. Remember that no-one knows the exact dosages of each ingredient inside this blend, as were not shown it on the ingredient list.

Ashwagandha Root Extract 

This is a herb thats been used in ayurvedic medicine for a long time, to boost general health. Although studies have shown that it has no effect on testosterone levels, its not completely useless…

Ashwagandha has shown to slightly improve your strength in the gym. And it doesnt cause any side effects; this means its not a key ingredient. but at least its not useless and doesnt cause any side effects.

Inositol-Stabilized Arginine Silicate 

Not much is known about this ingredient, and its actually a patented ingredient under the name of Nitrosigine.

In fact, the only studies we found conducted on this ingredient were paid for by the company who owns Nitrosigine - so we dont trust any of these results.

Until we see further evidence that it works (from a non-bias study), well consider this an unreliable ingredient.

Not only that, Inositol-Stabilized Arginine Silicate is believed to promote muscle pumps; this isnt a key reason why wed buy a testosterone booster supplement, so we dont think this ingredient is even needed here.

We still dont understand why Cellucor made a testosterone booster designed to also boost muscle pumps…especially when they couldve added nutrients proven to raise test levels instead.

Fenugreek Seed Extract 

Fenugreek Seed Extract is the best ingredient in P6 Extreme Pump; its proven to raise your testosterone levels and libido - these are exactly the benefits you want when buying a test booster supplement.

For this reason, were always happy to see Fenugreek Seed Extract on ingredient lists. In fact, our highest rated test boosters all contain this ingredient.

But theres a problem - its part of a proprietary blend. This means there might not be enough Fenugreek Seed Extract for it to work…

Ultimately, this is a great example of why proprietary blends are bad.

Ovine Placenta Powder 

Also known simply as Sheep Placenta, just knowing what this is puts us off from taking P6 Extreme Pump…

Basically, Sheep Platenta has been added into P6 Extreme Pump as its believed to regulate hormone levels and strengthen your immune system.

However, theres a reason why its not added into many test booster supplements - because it hasnt proven to work (meaning its an unreliable ingredient).


Agaricus Bisporus Fruit Extract

This is the first time weve seen this ingredient in a supplement before. Although its labelled as a fruit here, you know recognize it by its informal name - button mushrooms.

They can be a great addition to your dinner, and contain many vitamins to improve your general health. However, it hasnt proven to boost your testosterone levels - meaning its an ineffective ingredient in P6 Extreme Pump.

Stinging Nettle Root Extarct 

This is only other ingredient (alongside Fenugreek Seed Extract) thats shown to raise your testosterone levels. But you know the problem - its part of a proprietary blend…

If youve skipped the other parts of this review, basically there might not be enough Stinging Nettle Root Extract inside P6 Extreme Pump for it to work.

Eurycoma Longifolia Root Extract 

Also known as Tongkat Ali and LongJack, this is believed to boost your testosterone levels and strengthen your erections.

While it hasnt shown to affect you test levels, its shown promising results that suggest it might improve your erections. However, were still waiting for further evidence before were convinced it works.

For now, Eurycoma Longifolia Root Extract is an unreliable ingredient.


More commonly known as DIM, this has shown to stop testosterone converting into estrogen. However, no natural T-Boosters are strong enough to encourage your body to convert T into estrogen in the first place.

For this reason, companies often add DIM into their test boosters to fool you into thinking its more powerful. But dont be fooled.

Not only that, DIM has shown to actually promote the conversion of T into estrogen when consumed in large dosages - as its part of a proprietary blend, youre in danger of this happening.

Unfortunately, Cellucors gimmick has backfired massively here.

Side Effects

Theres 1 ingredient in P6 Extreme Pump that can cause side effects - DIM.

As weve mentioned, DIM can encourage your body to convert testosterone into estrogen when consumed in large amounts. For this reason, its the worst ingredient to add in a proprietary blend…but thats exactly what Cellucor has done here…

Heres the potential side effects from taking P6 Extreme Pump: 

  • Raised estrogen levels (DIM)

P6 Extreme Pump Review Conclusion

We werent sure why Cellucor made a testosterone booster designed to enhance muscle pumps. And after analyzing this testosterone booster, were not convinced its a good idea.

Basically, P6 Extreme Pump doesnt contain enough ingredients to be able to even boost your test levels (so its potentially a useless product).

Not only that, it definitely doesnt contain the right ingredients needed to enhance your muscle pumps - so Cellucor have failed in trying to do what they wanted to do.
