Pre Workout Beast Review

Pre Workout Beast Review


It had promise with Beta Alanine and Caffeine


7.5 Grams isn't enough to drown a nat, let alone get decent dosages


Yep, it's cheap. 

For a reason.


Tastes ok, not much to say about the feel. 


  • It's Cheap
  • It Has Got Caffeine
  • Tastes Ok


  • Under dosed on nearly every ingredient 
  • 2 Scoops Are Needed To Even Try And Hit Recommended Dosages

A product that is marketed to the masses and designed to sell in bulk at a low price. Not worth the tub it comes in to be honest. 

Note: This has been re-branded to Pre Workout Demon (It looks to be the same product)

When it comes to supplements, a lot can be said for positioning and marketing, especially when it comes to something as varied and open to different opinions as pre workout, today we look at one of Amazons best selling pre workouts, well best selling in 'Taurine Nutritional Supplements', but more on that later. Welcome to the Pre Workout Beast Review. 

As with other supplements that we have recently reviewed, this particular pre workout from a company called 'Demon Labz' (that's with a Z so you know they are legit) goes for bold, in your face wording and lettering, designed to entice you into their world. 

Pre Workout Beast Review

Maybe unicorns will re-appear when these are mixed? 

But moving away from the fact it's the number one in a category on Amazon, they heavily promote it via Amazons adverts and that fact it has a mysterious company name behind it, is this stuff actually any good? I guess I should crack on. 

Ingredients - What's Inside?

This might be one of the shortest lists I have ever had to create, and unlike other's that have stuck to simple and proven ingredients, this might not be a good thing. 

For this pre workout, you are going to get, 7 core ingredients, smooshed into 7.5 gram servings. Or if you can handle 'HIGH STRENGTH' you can have 15.3grams. 

Can you see where this is going?

If anyone can correctly guess what I am going to say before reading the next part, you can have a free tub of this stuff courtesy of me. 

Just plaster a few posts on Instagram and tag me, I will happily oblige. 

Right,  let's take a look at this massive list of properly dosed ingredients. 

Creatine Monohydrate

You know a review and an ingredients list is going to be good, when the one ingredient they throw at you, with the highest dosages, is an ingredient that needs time to properly 'soak' into the system before it becomes fully effective. 

And then under-dose it. 

Maybe I will take the Robert Downey Jr Gif and place it here again.

You will want to be taking around 5grams of creatine a day (as a standalone's cheap). It will help with recovery, protien synthesis and even support bigger lifts, but having 1.5grams in a pre workout will basically do nothing. 


Dextrose Monohydrate

It's time to start replacing your electrolytes that you might have lost from screaming at your Amazon account for wasting your money. 

You will notice products that aim to 'hydrate' you will contain Dextrose Monohydrate as it can be a useful product to help you restore blood glucose levels and even provide some quick and easy calories. 

Will it help in a pre workout, debatable. 


Beta Alanine has been linked to removing lactic acid, as well as extending how long it takes for you to become exhausted.  

I usually tell people that they will get the feeling of being touched by 1000's of tiny ants when they take Beta-Alanine for the first time, don't worry with this one. 

3.2 Grams is your optimal dose. You get 1/3 of that in this thing.


The theory behind having L-Glutamine is that it may help with aiding in the rebuilding of muscles after serious stress. 

But there has been zero proof that it can be useful for athletes to supplement this while training.

If you have a serious illness or potentially IBS, then grab some, the doctor will probably even encourage you to have some, but if you are an average gym rat, then currently there is no medical study that supports the fact it will help you. 


Taurine works synergestically with caffeine.

Helping to improve flood flow and helping to bring nutrients towards your muscle, as well as bringing on a 'sense of well being'.

Taurine can be great at helping reduce the jittery feeling you get from Caffeine, hence why every energy drink in the world contains the stuff. 

Recent studies have suggested that 1 whole gram will help with this. 

They have managed to get an ingredient with the base level amount needed in their pre workout.

Citrulline Malate

Citrulline is usually used to help with blood flow and elevating your nitric oxide levels.

You see Citrulline Malate alot in pre workouts, as it's shown to work, when dosed at at least 4.5 Grams. 

I take that part popper back. 1/4 of the dosage needed has been placed inside this concoction of crap that is Pre Workout Beast.


The staple to pre workouts is next, is the good ol' Caffeine!

The last ingredient found within this pre workout (minus some Vit B12), and it's dosed at 200mg.

I would never say that high doses of Caffeine is good for you, if you have experience with Caffeine before then 300 - 500mg is probably going to give you a little kick up the backside, if you are someone who has coffee throughout the day and is adding a pre workout as that added extra, then 200mg may have some affect on you. 

Though for your money, you might as well stick with the coffee rather than buying this. 

You can double this up and get a 400mg hit, which will please Stim Junkies or Caffeine fiends, and will probably hit those who don't expose themselves to the greater stimulants in the supplement industry as often. 

A word of warning, if you do enjoy coffee throughout your day, try not to double dose this, it takes a good 8 hours to get out your system and I have seen people chain coffees and then pre workouts together without thinking about the total Caffeine.  

Ingredients Verdict

Taurine is dosed correctly, and it has at least a base level of Caffeine in it. 

Other than that, the rest is pretty crap. 

Pricing (Plus Price Per Serving)

This really depends on what time of the day you purchase it, or even the day of the month, as the pricing jumps all over the place. 

At time of writing, Pre Workout Beast is being sold for £15.99. 

Which gives you a cost per serving of £0.39, or £0.78 if you decide that you need two scoops to satisfy your needs. 

But considering you are basically paying for the caffeine and not a lot else, is it really worth that. 

You can buy 200 Caffeine tablets for £11.50 that offer the same amount of Caffeine, without having to bother with the other stuff.

Pricing Verdict

It's cheap, but then so are caffeine tablets.

How Does It Taste & Feel?

Today's choice of flavour was the very popular Berry Flavour, because that was the first one that appeared when I decided to purchase it.

I would say that it does indeed have that tell tale pre workout Berry Flavour, which means it wasn't the worst thing I have ever put in my mouth. 

That's reserved for Poutin. 

Does this product actually do anything? 

Beyond giving a bit of a caffeine hit, not really no. 

There is no noticeable change in mood, energy or drive. You can feel some change due to the Caffeine, but nothing more than a decent energy drink would do. 

Taste & Feeling Verdict

Tastes nice, but has little to no noticeable effect.

Final Verdict

The one question that a lot of people will ask, is how did this product become number one in a category on Amazon?

Partly I believe down to aggressive marketing via Amazon Ads, promoting it and shoving it in front of you at every available opportunity and also the fact it is a lot cheaper than other brands and products.

People who are new to pre workouts may feel some difference because it contains Caffeine and a small amount of Beta Alanine, so people will always say it works, even if the actual product is basically awful. 

Personally, I would steer clear of this product and find something that may cost a small amount more, but you will see more noticeable results and differences.
