About P6 Extreme

If you’re looking to boost your testosterone levels without a prescription, Cellucor P6 Extreme claims to be a 3-in-1 supplement that increases your body’s natural testosterone production, inhibits estrogen formation, and minimizes DHT conversion. As a result, P6 Extreme is claimed to help increase your strength, lean muscle mass, libido, and energy levels.

But when it comes down to it, is P6 Extreme really a “next-level testosterone booster,” or is it just a waste of your money? We did some heavy lifting with the facts, and here’s what we learned.

Cellucor P6 Extreme Details

According to the P6 Extreme website, this testosterone-boosting supplement is claimed to be specifically formulated to optimize the conditions within your body to promote natural testosterone production. In fact, Cellucor’s P6 Extreme is claimed to be the “ultimate, legal route to supporting natural testosterone production.”

In order to accomplish these benefits, P6 Extreme is claimed to include the following ingredients:

  • Tribulus alatus extract 250mg
  • Proprietary P6 Extreme Blend 947mg
    • Ovine Placenta Powder
    • Black Cohosh extract
    • Beta Sitosterol
    • Wild Yam extract
    • Agaricus bisporus extract
    • Stinging Nettle extract
    • Bayberry extract
    • Salvia sclarea extract

Cellucor claims that you should take 2 capsules of P6 Extreme in the morning and another 2 in the evening, with or without food, with effects appearing after 5-7 days of continuous use. Once you begin taking the supplement, you can use it continuously for up to 8 weeks, at which point the manufacturer recommends taking a 4-week break. In addition, the company claims that P6 Extreme can be combined with other Cellucor products to enhance your overall results.

Important note: Cellucor produces P6 Extreme in a facility that may also process milk, eggs, soybeans, shellfish, fish, tree nuts, and peanuts, which could cause a problem if you have allergies to any of these items. P6 Extreme may also contain ingredients prohibited by some sports organizations, which could be of concern if you’re regularly tested for performance enhancing drugs (PEDs).

What Do Other Consumers Have to Say About P6 Extreme?

Overall, it appears that P6 Extreme has evenly mixed online reviews, with the most common compliments referencing increased lean muscle mass, no side effects, and boosted energy. However, some of the most common complaints reference almost the exact opposite, including failure to boost testosterone levels, high price, and unwanted side effects (headaches, light headed/dizziness, loss of appetite, etc.).

What’s the Bottom Line About Cellucor P6 Extreme?

As a man, you undoubtedly want to maximize your testosterone levels, whether you’re looking to boost results from your workouts or to replace testosterone lost as a result of the aging process. But is P6 Extreme the best way to accomplish this? Maybe, but consider the following:

Is P6 Extreme Effective?

First and foremost, while it’s true that any supplement will work better for some individuals than others, it’s important to note that there is very little clinical evidence showing that testosterone boosters work as well as advertised.

In fact, even in a detailed online review regarding P6 Extreme (see here) from a customer who experienced “positive changes,” their blood work indicated no changes in testosterone levels after 8 weeks of continuous use.

Mixed Online Reviews

As we mentioned above, based on the hundreds of online customer reviews for Cellucor P6 Extreme, it almost seems like a toss of the coin as to whether or not you’ll experience any benefits from the supplement. On top of this, you could experience unwanted side effects such as headaches, light headed/dizziness, loss of appetite, and more.

High Price

Even among testosterone boosters as a whole, P6 Extreme comes with a fairly hefty price tag, which when you consider that it may not work, might turn out to be an expensive experiment.

Bottom Line: Overall, Cellucor P6 Extreme may help if your primary goal is to lean up, although there are many other supplements/dietary changes that can help you accomplish the same results at a much lower price. However, if you’re expecting to experience a measurable increase in testosterone levels, you might end up disappointed. Whichever option you choose, be sure to check with your physician beforehand.

    Works for me

    • NYC,
    • Nov 14, 2014

    I started taking this product and within 2 weeks time definitely noticed a difference I was able to increase my workouts and have no tiredness after the fact. I then was involved in a bicycle accident where I was hit by a vehicle that took off. I had some pretty severe damages road rash broken bone in my back and a pretty badly twisted left arm and I truly believe that the fact that I was taking the supplement up until that accident help me in my recovery. The best thing I've noticed about this product is during the time of my recovery I was eating a lot of very unhealthy comfort food and expected to gain weight because not only was I not working out but I was eating a lot of junk food and much to my surprise I did not gain any weight and I actually lost a couple pounds I highly recommend this product to anybody over the age of 35. I myself am 48 and definitely feel the difference from taking this product.

    Bottom Line: Yes, I would recommend this to a friend
