Cellucor P6 PM Review

There’s nothing quite like a good natural T booster supporting your hormone output all day long. Well, except maybe a good natural T booster supporting your hormone output all night long. That’s quite like it to be fair.

Now, overnight testosterone boosting might not seem to make sense at first. It’s the main fuel of physical activity, so surely only cat burglars, bouncers, vampires and other denizens of the night would need their T flowing after hours?

NO. Increasingly research is demonstrating that hormones can really benefit from what you do later on. That’s why a lot of brands now offer a booster to take over on the nightshift. Cellucor P6 PMis one of those.

Cellucor P6 PM

P6 PM is designed to be stacked with one of Cellucor’s day time boosters and claims to provide T support and promote restful sleep. I go through periods where I struggle ro sleep myself and studies show that lack of shut eye severly impacts T and limits performance, so anything that may help, I’m willing to give the time of day (or night)

You’ll certainly be going into Cellucor P6 PM with your eyes shut on one level. That’s because the formula uses a proprietary blend. This is a loophole that means companies don’t have to give each ingredient’s dose. Just the names and and overall mix volume.

There really is no legit reason why you shouldn’t be given all the info, but sadly these blends are a still fact of life for some boosters and you just have to do the best you can with the facts your given. Let’s do that now.

How Does It Work?

At a Glance

  • ZMA combination to support T.
  • Tribulus to supposedly stimulate male hormone
  • Vitamin B6 to limit estrogen
  • L-Theanine, passionflower & Melatonin to promote relation and sleep.

We’ll check out all this in more detail after the scores

The Scores

The Scores

In fairness Cellucor P6 PM isn’t all bad. There are good amounts of important minerals like zinc and magnesium, with a solid amount of vitamin B6 to keep your estrogen in check.

Some of the ingredients to promote relaxation and better sleep have shown that they work in studies, but thanks to the proprietary blend we’ve no idea if they’re all here in active doses.

The biggest mistake P6 PM makes though is using Trib as its main T booster. Science blew claims about this stuff out the water decades ago and it’s ridiculous some brands have the nerve to try and charge serious cash for it. Speaking of which…


At around $40, Cellucor P6 PM is about mid range for a booster. But remember this is to be paired with a daytime option as well. If you are going to be doubling up your bill, we’d recommend you choose a more impressive candidate than this.

Most of what we’re sure is good about P6 PM is the ZMA content and you can pick up a purely ZMA supplement cheaper. The extras here need to be much more convincing to justify your hard earned cash.


Cellucor P6 are a well established name in the supplement game, so we’ve no worries about the safety of the product. That said there’s plenty about this booster that grinds our gears.

The proprietary blend for one. Sorry to keep going on about this, but there’s no reason to keep customers guessing on important info. It’s your money and more importantly, your body so you have a right to all the facts. As for still pushing trib, some brands really need to wake up and smell the coffee.


P6 PM scores pretty high on sites like Bodybuilding.com (albeit at the time of writing there were only 8 reviews. Most report improved rest and better physical performance).

The rest aspect sounds promising, but it’s difficult to tell how much this helps T. You’re going to notice those benefits during the day and if you’re taking another booster, how can you tell what P6 PM adds? A detailed testimonial section could’ve gone into these questions in detail but sadly we don’t have one.


Cellucor are a sports nutrition company who started in 2002 out of Bryan, Texas. Since that time they have released a vast range of supplements including testosterone boosters, pre and post workout aids, amino acids and protein products.

They have plenty of professional athletes carrying their flag and a solid fan base. We take issue with a few formula choices, as you’ve seen, but all in all, very strong.

How Do I Take It?

Users take 1 servings of 4 cap just before bed.

Under normal circumstances we’re no fan of single serve supplements. They just don’t sustain their effects as long as boosters that are regularly topped up. So chances are Cellucor P6 PM fails the Lionel Richie test (All Night Long) but since you’re sleeping there’s not a whole lot you can do.

Insomniacs or people who are up and down to the bathroom regularly you should aim for 3-4 servings, spaced out over a number of hours.

Any Cellucor P6 PM Side Effects?

None pf the ingredients here give us any cause for concern as far as side effects. We’ve had no reports from readers.

Where Can I Get It?

Cellucor P6 PM is available on Bodybuilding.com for $39.99 getting you a months supply.

Ingredients – In Detail



Zinc is a vitally important mineral for T and it’s not always easy to get enough of from diet alone. Essential building blocks like luteinizing, growth and folicle-stimulating hormones all rely on getting enough.

It is possible to get too much zinc however and while the 30mg in P6 PM will be fine, you should be careful if you’re pairing that up with another lot of zinc in a daytime booster. 40mg is most people’s upper limit.




Magnesium is a stand out choice because it is effective in reducing Sex Hormone Binding Globulin. This is a protein which attaches itself to T rendering it useless.

450mg is a solid amount and should get the job done.



Vitamin B6

Despite being called the female hormone, guys have levels of estrogen too. If those levels get too high then testosterone levels suffer, so estrogen reduction ingredients like vitamin B6 are useful.

B6 slows production of estrogen and reduces the influence of what’s already active in our system. 10.5mg is a strong amount to make a really difference.


Tribulus Terrestris

It was all going so well. We know Cellucor P6 PM is supposed to promote strong sleep, but the team must’ve been sleeping for decades if they think tribulus is still a good pick.

Trials of its influence on testosterone continue to show it does nothing except give a boost to your libido in massive amounts. We’re in to the 855mg proprietary blend now so we’ve no way of knowing how much is here, apart from to say too much. A waste.



An amino acid which promotes relaxation with out any actual sedation. Studies are mixed but even the most positive say you need about 200mg and we have no idea how much we’re getting again.



Very high levels of this have been known to make people drowsy and some studies have shown it can reduce the time it takes users to fall asleep, but results have been mixed.



A ‘downer’ neurotransmitter which helps the body slow down and achieve quality rest. The problem is GABA isn’t great for supplementation because it doesn’t cross the brain/blood barrier easily. To say for sure whether it’s of use here we’d have to know how much was on offer. It’s doubtful there’s enough,



Melatonin is the hormone your brain releases to slow the body down ready for sleep. It does this successfully and with no ill effects in dosages as low as 2mg, so even though there’s a question mark over how much P6 PM contains, there’s probably enough.


Anything Missing

The main T booster in this product is tribulus, which really has no credibility left as a natural test booster. D-Aspartic or vitamin D3 would’ve been much better choices.


P6 PM isn’t all bad. At the end of the day though (literally) any booster that makes Tribulus its MVP for T is never going to be close to your best option.

If you can afford to add a night booster to your supplement stack, you better believe there higher quality options out there. When we find them you’ll be the first to know. Watch this space.
