P6 Black did not make it to the top 10 list of testosterone boosters : See complete list here


  • Contains many proven ingredients
  • Good dosage of Zinc
  • Missing some key ingredients
  • Contains proprietary blends
  • Expensive

In this P6 Black review, we’re going to find out if this testosterone booster contains good ingredients and if it really works.

Here’s the deal:

When it comes to testosterone boosters, most products simply aim to increase overall natural testosterone release in the body, which should then help you pack on more hard, lean muscle in the gym.

P6 Black by Cellucor approaches things from a different angle.

In addition to helping boost natural testosterone levels, this supplement also helps to increase your mental focus, drive, and determination as well.

How does it stack up? Let’s look at what you need to know


p6 black review

One glance at the label of P6 Black shows us that you are getting some vitamins and minerals, along with two different blends.

Let’s look at the checklist of ingredients of the best-proven testosterone boosting ingredients and see if P6 black contains them:

  • Check mark symbolD-Aspartic Acid
  • Check mark symbolZinc
  • Check mark symbolVitamin B6
  • Check mark symbolVitamin D-3
  • Check mark symbolMagnesium
  • X symbolFenugreek
  • X symbolAshwagandha
  • X symbolBoron
  • X symbolVitamin K-1
  • X symbolGinseng

P6 Black contains 5 out of the top 10 ingredients to look for in a testosterone booster.

While it’s great this company tells you how much of each of the first four nutrients you are taking in, the blends give you little information whatsoever as to dosages, so it gets very hard to know precisely how beneficial this product will really be.

On the vitamin D standpoint, you’ll be getting 833% of your total daily intake, which is a great start.

Vitamin D is a nutrient most people are not getting enough of in their daily diet and studies[1] do suggest that men who are low in vitamin D due to seasonal variations in sunlight may also suffer from low testosterone levels as well.

On top of that, you are getting the standard ZMA combination that so many testosterone boosters provide – zinc, magnesium, as well as vitamin B6.

The dosage of these nutrients is also right in line with what they should be for optimal effectiveness.

One thing to note here though is that studies[2] indicate that if you are eating a diet that is sufficient in zinc, you are likely to notice any additional benefit with this supplement, over and beyond what you are already getting through nutritional means.

Finally, also included is copper, at 100% of your total daily intake.

Moving on, you then get a Nootropic Testosterone Mix, which contains D-Aspartic acid, -Serine, Alpha GPC, as well as 3,3-Diindolymethane and Androstenolone.

Studies[3] have indicated that D-Aspartic acid is involved with the generation of steroid (testosterone) hormones in the body, therefore this could hold some promise at giving you additional results due to supplementation.

On top of that, you’ll get an androgen support matrix, which contains Zinc, Mucuna pruriens, Andrographis paniculata Aerial Parts, cholecalciferol, as well as copper.

Even though it’s a decent product it did not crack our top 10 list for the best testosterone boosters on the market. 


  • Vitamin D can help with the natural elevation in testosterone if you are already at a relatively low level.
  • Because of vitamin D, this can also provide bone-strengthening benefits
  • The ZMA combination is effective for increasing exercise performance and strength levels
  • Using this product will likely also have you sleeping better at night, thus experiencing higher levels of testosterone because of that as well
  • You should experience a slight mental edge while using this product, while also experiencing increased memory
  • May help to decrease the signs of aging thanks to the DHEA (androstenolone it contains)


  • The product comes with a proprietary blend, therefore it is really hard to figure out just how effective it will be
  • Many of the ingredients won’t do a lot more than just boosting libido levels and sexual performance
  • It is a high priced product, so not something for those on a budget
  • The product is missing a few key ingredients.
  • The capsule number per serving is quite high, especially beyond the first cycle, so for those who dislike swallowing pills, this can be a serious drawback.
  • It contains proprietary blends and is missing a few key ingredients and therefore it did not make it to the top 10 list for testosterone boosters.

 The Verdict – Does P6 Black work?

Overall, P6 Black is quite a pricey product.

It does offer some good ingredients however including the Vitamin D and ZMA blend, so if you are currently low in testosterone, you should see good improvements in that area.

If you already have relatively normal testosterone levels, however, you may not notice as dramatic of a difference.

Additionally, most men using this product will see libido and sexual performance support thanks to the various herbal ingredients added into the mix and you should notice some improvement with your focus when you are in the gym.

If you are interested in it for those reasons and have the money to spend, this can be a good option to help give you the added edge you are looking for.

If you are on a budget, however, consider simply purchasing vitamin D and then a ZMA product separately and you’ll still likely see good results.

Overall it’s a good product but we believe there are some better options available for a testosterone booster.
