P6 Xtreme vs. P6 Ultimate

P6 Xtreme vs. P6 Ultimate

Sorry, peasants. The Cellucor kings have spoken.

And they demand payments up front — no loans or in-store credit.

If you’re wondering WTF we’re blabbering about, scroll down to Round 4 of this comparison review, then scroll back up here and say with us: WTF?!!?? At those prices, these testosterone boosters better come with a Rolls Royce and mail-order bride.

And if they don’t come with either, they better at least boost testosterone. That’s not too much to ask, right? Let’s read the remaining rounds to find out.

Round 1: Formulas

Proprietary blends. Ingredient brands. Sheep placenta.

These are definitely Cellucor P6 products. Let’s see which one’s the better (or if they’re essentially the same supplement), starting with:

P6 Xtreme: Brains, Brawn, and Balls

Cellucor P6 Xtreme takes an extremely layered approach towards advanced anabolic gains with its 5-in-1 proprietary blend. Those five layers being:

  1. Testosterone Boosters – Ashwagandha, Tribulus alatus, Ovine Placenta
  2. Focus and Mood Support – Alpha-GPC, Zembrin
  3. Estrogen Regulator – Agaricus bisporus (White Button Mushroom)
  4. DHT and Prostate Support – Saw Palmetto, Stinging Nettle
  5. Sexual Health and Energy – Tongkat Ali

Extremely layered, yet how extreme are the layers individually?

Mehhh, they’re aight. For an extreme testosterone booster, P6 Xtreme surprisingly misses out on many of the extreme testosterone booster ingredients, e.g., D-Aspartic Acid, Zinc, Mucuna pruriens… Ashwgandha may boost testosterone. Tongkat Ali may boost testosterone.

And that’s about it!

Adding Alpha-GPC and Zembrin notches in a nootropic angle to this formula, but even so …why not go for gold and give us the noots that actually benefit bodybuilders? E.g., Rhodiola, N-Acetyl-L-Tyrosine… By stretching in five different directions, P6 Xtreme achieves an impressive hybrid test booster design, but fails to reach far enough on any of those pathways.

P6 Ultimate: Performance and Pump

P6 Ultimate follows a fairly standard Cellucor P6 design, sharing roughly the same ingredients with P6 Xtreme: Ashwagandha, Ovine Placenta, Agaricus bisporus, Stinging Nettle, Tongkat Ali, Alpha-GPC, and Zembrin. Yet, P6 Ultimate takes it up a slight notch by also including the popular sex enhancing herb Fenugreek as well as the BIG List of T-Boosters topper Vitamin D.

In terms of formula design, P6 Ultimate takes a much tighter approach to male enhancement, trimming its hybrid levels down to three:

  1. Testosterone – Aswagandha, Fenugreek, Tongkat Ali, and more.
  2. Muscle Pumps – N.O. boosters Nitrosigine and Arginine.
  3. Cognition – via Alpha-GPC and Zembrin

The nitric oxide booster brands of L-arginine may elevate P6 Ultimate to bodybuilding PWO status, qualifying it as an effective pre-workout performance enhancer as well as a more long-term muscle recovery booster (via Fenugreek).

While P6 Ultimate doesn’t work as the most extreme or ultimate testosterone booster, it is more extreme and ultimate than P6 Xtreme, earning it the Round 1 win.

Round 1… P6 Ultimate Wins.

Round 2: Dosages

Another Cellucor standard: the proprietary blend.

And both P6 Xtreme and P6 Ultimate have it. Howeva…

P6 Xtreme only has one proprietary blend:

  • P6 Xtreme™ Blend – 2600 mg shared by nine ingredients, allowing for a potential average 288.9 mg per ingredient.

Whereas P6 Ultimate has two proprietary blends:

  • P6® Testosterone and Performance Blend – 2275 mg for seven ingredients, allowing for a potential average 325 mg per ingredient.
  • P6 Ultimate™ Cognitive and Pump Blend – 1225 mg for four ingredients, allowing for a potential average 306.3 mg per ingredient.

While taking the disappointing proprietary route, P6 Ultimate outperforms P6 Xtreme in Round 2 by doing two things: 1) showing two dosages for a little more transparency than P6 Xtreme’s one dosage, and 2) supplying more milligrams overall for a higher mg per ingredient average.

Thus, the Round 2 winna:

Round 2… P6 Ultimate Wins.

Round 3: Ingredient Quality

In this reviews, Cellucor tends to make up for its Round 2 sins in the third round: Ingredient Quality — by supplying generally premium, powerful ingredient options. In both supplements, we’re seeing branded Ashwgandha (Adaptatest for P6 Xtreme, KSM-66 for P6 Ultimate), AlphaSize branded Alpha-GPC, Zembrin, and LJ100 branded Tongkat Ali.

Even the non-branded ingredients are looking pretty solid in both formulas as well. P6 Xtreme does something particularly impressive by opting for the Tribulus alatus form over the far more common Tribulus terrestris species — the latter doesn’t seem to boost testosterone whereas the former might do so.

The capsules could be cleaner in both supplements, yet we’re not concerned with any major side effects or red flag results. Both Cellucor products are generally natural and safe.

All-in-all, the P6 Xtreme vs. P6 Ultimate comparison review hits a solid equilibrium in this round. Props to Cellucor.

Round 3… Tied.

Round 4: Price

P6 Xtreme VS. P6 Ultimate
1 Bottle (30-day supply) $169.99 1 Bottle (30-day supply) $159.99
Price Per Capsule $1.42 Price Per Capsule $1.07
Price Per Serving $5.67 Price Per Serving $5.33

Both Cellucor supplements reach equilibrium in Round 4 as well, this time not to the customer’s benefit but to Cellucor’s. Holy f*ckin’ snikeys.

Round 4… Cellucor Wins.


Cellucor customer reviews tend to be a little wonky, due to the manufacturer’s immense popularity. For either supplement, the customers either love or hate the results. Here at Best5, we’ve landed somewhere in the middle on each product.

Why? Because we’re anti-conformist AF.

No — because these supplements simultaneously impress with their design, yet disappoint with their ingredient choices. The effort ranking these supplements somewhere in the middle of our 5-star ratings.

However, what we can’t get over are their prices. Who wants to buy a $150+ supplement every single month?? Especially in the 2017 market, which holds much better testosterone boosters for much less.

Not to attack you Cellucor fans. You do you. But while you’re doing you, do P6 Ultimate, too. It’s better than P6 Xtreme, and slightly less expensive.

In the P6 Xtreme vs. P6 Ultimate fight, the winner by Majority Decision is…



Res-Q Natural Male Testosterone Review – Natural Libido Pumps Crammed in Unnatural Tablets

Res-Q Natural Male Testosterone Support has come to the… REESSSCUUUEEE… ( ͡º ͜ʖ ͡º) Very punny, friend-O. But seriously, what’s up with this supplement? If the implication is that Res-Q has come to rescue low testosterone levels through natural testosterone supplement, we have to wonder how Res-Q plans on doing this with its ho-hum selection of ingredients…. [Read More]

P6 Black vs. P6 Ultimate

P6 Black and P6 Ultimate share the same Cellucor series of testosterone boosters. But if P6 Ultimate is truly the ultimate P6 test product, is there any real comparison? There better be: P6 Ultimate is one of the most expensive testosterone booster supplements on the shelves in 2017, counting nearer to the $200 mark than $100…. [Read More]

Prime Male vs. Super Male Vitality

What’s more important to you here: Boosting testosterone or disrupting the globalist agenda? The question is a trick: Testosterone disrupts the globalist agenda. And we’ll be God damned if we’re about to let a bunch of elitist, gender-bending lizard-people from on-high poison our masculinity with their emasculating estrogen mimickers. So, the real question is which… [Read More]

Prime Male vs. P6 Ultimate

In the jungle, the mighty jungle… The lion doesn’t sleep. The lion benches presses 315 lb, squats ass to the grass, and soothes its muscles in a post-workout ice bath whilst re-reading a Prime Male serving of Hemingway. Or at least that’s the usual daily schedule of the lion. Today, the lion’s plans are disrupted… [Read More]

Super Male Vitality vs. AnthroPlex

Do you want super enhanced male vitality? Or do you want …human parts… ? With Super Male Vitality, the bio-benefits are advertised in the name: this is a supplement designed to enhance your male powers and manly quality of life. With AnthroPlex, which etymologically translates to “having human parts or units,” the point of this product is somewhat… [Read More]

AnthroPlex Review – The Companion Capsules to Super Male Vitality

Anthro – “human” Plex – “having parts or units” Meaning this supplement translates to “having human parts or units.” This is nonsense. Nipples are technically anthroplex by this literal translation. And there’s a reason we don’t see people swarming to the stores for nipple supplements. Okay, bad analogy. But you get it. Anthroplex might be a confusing name… [Read More]
