Cellucor P6 Xtreme Ultimate Testosterone Formula Review

Cellucor P6 Xtreme Ultimate Testosterone Formula Review


We featured the sister product of this called the P6 3-in-1 back in April.

It did not fair particularly well due to there being a proprietary blend, tribulus and a number of rather unproven ingredients that will not assist in stimulating your body in to producing more testosterone.

Now this is called the ‘Xtreme Ultimate’, I am hoping the issues have been rectified and Cellucor took my previous points on board to produce a much better product.

In ture Cellucor spirit, this is one of many, very similar looking products that share many identical ingredients.

In terms of covering all bases and casting the net as wide as possible, I do not think Cellucor can be beaten.

The prices reflect this, too.

Cellucor P6 Xtreme Ultimate Testosterone Formula First Look:

As with all Cellucor products it looks fairly similar, to the point that it is quite annoying and you really have to double check which product you are buying.

It is a bit like choosing between the American Crew hair products, get it wrong whilst you are making a rushed decision and your hair will look all wet and shiny when you just wanted a matt finish.

However, confusions aside, both products do look of a good quality.

Ingredients: The Science


So where it stands out from the crowd in terms of packaging, it all sort of comes crashing down again and that’s from just a quick glance.

There’s actually less weight per serving that it’s sister product which doesn’t bode too well and once again we are faced with the unknown of a proprietary blend, this really pisses me off.

So as I have discussed many times before, a proprietary blend allows the manufacturer to only list what ingredient is present in the blend but not the actual amount, it is basically a farce that is widespread throughout the industry.

Ashwaganda – Studies have shown that treatment with Ashwagandha root extract resulted in a higher level of testosterone and a concomitant increase in serum levels of LH among infertile men having sub-optimal testosterone levels.

It’s difficult to see if the same result would be found with guys who do not have any fertility issues.

Ovine Placenta Powder – I cannot find any journals or scientific studies to prove that this will increase testosterone.

The only information which relates to testosterone was on websites advocating this product which seems a bit one sided.

Otherwise it seems if you are a well financed housewife there are plenty of London health clinics that will happily take many of your British pounds in exchange to rub a sheep placenta on your face.

 Agaricus Bisporus – White button mushrooms to you and me, these are seen to be a aromatase inhibitor, therefore they reduce the production of estrogen which can maintain a higher testosterone level.

If a man suffers from too much estrogen they can get bitch tits – puffy nipples.


Saw Palmetto – this fatty acid was long touted to help boost testosterone levels, but those claims turned out to be false.

It is effective in suppressing prostate growth though. So could help if you are taking steroids or Prohormones.


Nettle Root – Good for reducing inflammation and an enlarged prostate but has no effect on testosterone.


Tribulus – Once marveled, now known to have no effect on testosterone levels, by now supplement manufacturers should really let go.  Avoid like a medieval plague if you are looking for muscular gainz.


Longjack Extract – Eurycoma (Tongkat Ali, LongJack) is a pro-fertility agent and aphrodisiac that appears to have a large body of evidence supporting this role and some evidence suggesting it may be an anti-estrogen and pro-erectile agent.

However, there is a lack of evidence for testosterone boosting in humans, although some very limited evidence in animals.


Alpha GPC – Appears to have cognitive-enhancing properties (no human evidence exists to support this in otherwise-healthy youth, but it does have support in rodents) and attenuate the rate of cognitive decline in the elderly.

In regards to reducing the rate of cognitive decline, alpha-GPC at high doses (1,200 mg) does appear to be somewhat effective – we don’t know what is included here.


Zembrin (Sceletium tortuosum) – Initial tests cite that it’s possible in promoting a sense of wellbeing and relieving stress in healthy individuals and for treating clinical anxiety and depression.

This was based on 25mg being administered, again we are non the wiser to how much we are getting in this product.



4 pills per day – this amounts to 2600mg of ingredients daily which is short of our favorite booster, TestoFuel and it’s sister product.

4 pills per day is a great way to avoid peaks and troughs of the ingredients to take full effect.

However, instead of being equally spaced throughout the day Cellucor suggest have 2 tablets at once. Strange.


Oddly, this is a very similar product to P6 3-in-1 bar 3 ingredients, to add to that there is less weight in this product yet it is hailed as the Xtreme and Ultimate version, hmmmmm.

However, what we have here are 9 ingredients, two of which are being touted to help with mood and cognition, but we are not sure of the total of mg for each and that would seem to be an important factor from initial tests.

That leaves 7 ingredients to hit hard and get those testosterone levels jacked, however, you would be hard pressed to get any results from those.


Well a big, massive proprietary blend which isn’t quite as big as the proprietary blend in the other product.

In fact it is all pretty confusing; it’s sister product which isn’t as ‘extreme’ nor as ‘ultimate’ is doing a better job, although not a successful one, at being a testosterone booster. Not of it makes any fucking sense.

It is almost as if there is some sort of marketing graduate behind the whole scheme and we are all being duped by this spotty kid.

He probably didn’t even major in marketing either, probably something fluffy like music.

There is not one, solid, proven testosterone boosting ingredient present here and this isn’t a cheap, throw away product either.

Cellucor P6 Xtreme Ultimate Testosterone Formula Conclusion:

This really is nothing more that marketing smoke and mirrors.

This cannot even be called a testosterone booster.

There’s a mish mash of ingredients with the exact amounts of each cloaked by a proprietary blend, the actual blend weighs less than our #1 Testosterone booster and unlike TestoFuel not one ingredient is proven to help raise testosterone levels.

There are two ingredients that may help towards mood and cognitive function but at these doses it is unlikely to have any effect.

This product should be called the Xtremely Unlikely Testosterone Booster.
