BEAST Nutrition Beast Mode Black Extreme Pre Workout Review First Look:

I have shit loads to do this evening.

My mate from Perth, Australia is over tomorrow afternoon and the spare room needs to be painted tonight.

I also need to cycle home, eat my dinner and then lift some weights.

It is already 17:24

If I am honest, I am rushing all of this because I want to be out on this piss this weekend, not doing work, and I want it all to be sorted before the carpet fitter comes over to the house as well as the furniture delivery people.

Guess what? It doesn’t end there, I am going to have my front yard landscaped and a car parking space added to it as well.

This means I am very busy in the next few months, therefore, when I hit the gym i do not want to be messing around. I want to be focused, ready, sharp and charged to explode.

A workout need not be more than 60 minutes, that is plenty of time to get everything done.

Phone off, distractions at bay, just the weights and the right frame of mind.

Hence why I have been trying this pre workout tonight from Beast Sports Nutrition.

It looks bold, it looks good and professional. Nothing about it states failure so I am excited to try it.


Caffeine – It stimulates the central nervous system (CNS), heart, muscles, and the centers that control blood pressure to give you an extra boost and hit that PB.

Caffeine Anhydrous is the purest form of caffeine so always look out for it.

This is found in 4 Gauge which is the best pre-workout.

Beta-alanine  – Supplementation of this non essential amino acid aids the production of carnosine. That’s a compound that plays a role in muscle endurance in high-intensity exercise.

That said, studies have not exactly been positive nor entirely conclusive.

Thiamine (Vitamin B1) – Thiamine is required by our bodies to properly use carbohydrates.

Some research suggests that taking thiamine together with pantethine and pantothenic acid (vitamin B5) does not improve muscle strength or endurance in athletes.

Taurine – It has been touted that Taurine can help mental performance.

Early clinical research suggested that taurine, in combination with caffeine, glucuronolactone, and B vitamins, can improve attention and reasoning in adolescents, but does not improve memory.

However, there is insufficient evidence to prove this is always the case.

Vitamin B12 (cyanocobalamin) – Gives you more energy and boost your metabolism, helping you shed unwanted pounds. Ensure you are not deficient in Vitamin B12 so you can do that quick 10 miler at 5am…

Agmatine – Agmatine is considered to be a neurotransmitter and neuromodulator.

The majority use agmatine injections, not oral ingestion and there is still no evidence that working memory is enhanced with agmatine supplementation.

Dimethylaminoethanol DMAE – This compound can help with cognitive impairment, however, results from studies are a bit patchy. This is not classified for use as a food additive in the USA. Has been marketed as DEANOL.

Glycerol – Seems to be most effective when administered rectally (in your ass) as a laxative.

Choline BiTartrate – Choline is mostly used for either its cognitive boosting properties or as a liver health agent, able to reduce fatty liver buildup.

It may also be a stimulant although this is based on anecdote. Requires around 250-500mg per day for cognitive benefits.

Choline does not offer any significant benefits for aerobic capacity, fatigue or training capacity.

Yohimbe – Related to Yohimbine, Yohimbe is a powerful stimulant and used to increase fat loss as well as assist with erectile dysfunction. Can cause a host of other problems though, this is in out supplements to avoid list.

Theacrine (1,3,7,9-tetramethyluric acid) – An alkaloid molecule which can be seen as a structurally modified version of caffeine.

However, although it is similar to caffeine whereby it has a sedative effect at relatively low doses, but where this sedative effect with caffeine is at an impractically low dose with theacrine it is the dose normally consumed by tea.

Research on Theacrine is really too sparse though to cast any real assertions.


There’s a total of 7700mg which is mediocre at best and pretty low at worst.

There’s so much more offered with other pre workout supplements on the market which makes you wonder why anyone would buy a low dosed option.

The taste was a bit odd, it’s supposed to be blue raspberry but it was a bit strange tasting.


Effects & Benefits:

Caffeine is probably the most well known ingredient found in here and its ability to give you a buzz and some energy is renowned, most used by people who work long hours or are hungover.

Beta-Alanine does nothing other than provide a tingling sensation which makes you think your veins are coursing with energy.

B12 helps provide your body with more energy, it can also raise the metabolism which will result in more calories burned.

Choline can help with cognitive function at these sort of doses which is handy, especially if you like to do a spot of Sudoku while bench pressing.

B1 will help your body use carbohydrates for energy but that is about where the benefits end.

How did it feel?


Even though there’s a large 400mg of Caffeine and over 1500mg of Beta-Alanine I felt nothing.

I even felt drowsy and tired.

I certainly didn’t feel motivated or energized at all.

Fuck it off and don’t bother.


So much of this pre workout doesn’t actually provide any benefit at all.

If we really take a good long hard look at this ingredient profile only 5 of the 11 have substantial evidence and conclusive evidence of beneficial effects.

That’s less than 50% conclusive.

I am about 50% conclusive and look at the shit state I am in!

Joking side, that leaves us with a whole vast array of ingredients that just shouldn’t be present.

Yohimbe while a strong stimulant can really cause some health issues, notably cardiovascular.

Theacrine is just too weak, Glycerol needs to be shoved up you ass to work as a laxative and I, for one doesn’t need or want explosive shit anytime soon.

DMAE, Agmatine and Taurine just have very patchy results concerning their benefits.

Agmatine at best needs to be injected as well.

Beta-Alanine is great at making you feel tingly, but that’s it’s limits.

Overall the dose is very low considering the competition that offers around 100% more than this.

BEAST Nutrition Beast Mode Black Extreme Pre Workout Review Conclusion:

So what we have here is a bit of an overall weakly dosed pre workout supplement whereby less that 50% of it will offer any benefits.

That, in anyone’s book isn’t ideal.

Especially not from an established market forerunner with many other products available.

This omits too many other effective ingredients that will help with energy, focus and increased blood flow as well as nitrous oxide increases.

I think this is all apparent with the real woeful performance from the product as I felt nothing. Nothing at all.

Didn’t even touch the sides, mate.
