My Medi Evil Berserker V2 Amino Review

My Medi Evil Berserker V2 Amino Review First Look:

I have been feeling exhausted tonight. I really couldn’t get myself in that gym.

I’ve just recently bought a cyclocross bike which is the first bike I have ridden in about seven years that has gears.

Yes, normally I ride a fixed gear bicycle but my 9 mile commute to work wasn’t going fast enough for my liking so I have brought a geared bike in to the mix.

Thank fuck I have too. My commute in to work has just slashed by half pretty much.

So, I have been riding hard, with lots of pedaling.

However, I was shattered when I got home and the gym just didn’t seem too appealing.

I clearly needed something to wake me up, re-focus and energize.

Could this pre workout from Medi Evil be able to do just that?

It looks potent, so I was hoping it would be potent.

There’s plenty of ingredients as well which must mean something is effective.

The thing is, there are plenty of pre workout supplements available, so why should I chose this one?

The fact is, not all pre workout supplements are even effective or offer any kind of real world benefit.

The main issues that I come across are:

  • Doses of effective ingredients that are too low to be of any benefit
  • Unproven ingredients
  • Proprietary blends
  • Potential harmful ingredients
  • It just doesn’t work

With this in mind, and with my experience of using many pre workout supplements before I hit the gym or play rugby.

I am keen to find out exactly what is beneficial so we can extract the best from ourselves and perform to a higher standard.

What can a pre workout really do?

The use of a pre workout supplement is traditionally to provide a more explosive and focused workout when you hit the gym.

This is achieved by providing high levels of stimulants to fight fatigue as well as increase the blood flow to the muscles and organs.

They can also include other ingredients that are known to help increase cognitive function so you can effectively zero in on your goal and help smash it.

However, they are no commonly used by students looking to concentrate while stay up late as well as gamer’s and even machine operatives or long distance drivers.

The main key benefits are:

  • Increase energy – Smash your workout with more intensity
  • Motivation – Get straight out of bed for an early morning gym session
  • Improved focus – Zero in on your weights program or even revise harder
  • Alert – Stay alert and improve concentration

However, not all pre workout supplements are equal, and some are downright terrible or contain potentially dangerous ingredients in dangerous doses, or concealed doses.

We analyse each one with an in depth review.

Ingredients: The Science


This is found in many pre workout supplements or products designed to make you more vascular.

L-Arginine opens up the blood vessels and arteries to assist with blood flow, nothing really to do with testosterone but may assist with any impotency issues that are not helping you attain that hot chick in the gym who is 15 years your junior.

However, you will require 5g per day alone!


This is used as a sports performance and cardiovascular health supplement. L-Citrulline supplementation results in reduced fatigue and improved endurance for both aerobic and anaerobic prolonged exercise.

An increase in growth hormone has been noted with exercise, but not at rest.

L-citrulline boosts nitric oxide production in the body.

Nitric oxide helps your arteries relax and work better, which improves blood flow throughout your body.

Supplementing can help lower blood pressure in people with pre-hypertension.

This is often found in the best pre workouts.

To supplement L-citrulline to enhance sports performance, take 6,000 – 8,000 mg of citrulline malate about an hour before exercise.

You can read more about Citrulline and its benefits for exercise, here.


BCAAs (typically a combination of  L-Leucine, L-IsoLeucine and L-Valine) play a critical role in muscle development because they are metabolized in the muscle rather than the liver.

Because BCAAs are metabolized in the muscle, they can be used for building new proteins or for energy.

However, Supplementation is not necessary if you eat eggs and meat regularly. However, if you are a vegetarian or vegan, supplementation will be vital.

BCAA’s are often included in whey protein supplements, too.

Salt (sodium)

An essential mineral; its consumption is critical to our health. However, Americans plus a lot of Western countries do consume double the recommended daily intake.

Excess sodium may not raise blood pressure, but it is associated with other health issues, such as kidney damage and an increased risk of cognitive decline.

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…

Vitamin B6

Using it in its most natural form, pyridoxine, B6 is an essential nutrient to raising the body’s metabolism and aiding the fat burning process.

It also contributes to the reduction of fatigue and if you are not getting enough B6 you can suffer from cognitive decline as well as depression.

B6 also contributes to normal and healthy hormone levels.

Beta Vulgaris (Beet)

Beet can also increase nitric oxide in the body. This chemical can dialate blood vessels and was popular with athletes at the London 2012 Olympic Games.

This is also found in 4 Gauge which is rated as the best pre workout, however, it is not commonly found in many others.


Magnesium is a mineral with many uses and functions, not withstanding protein synthesis as well as muscle and nerve function.

Along with Potassium and Calcium Magnesium also contributes to healthy heart function and muscle contraction – great for exercise!

If you are suffering from a Magnesium deficiency it can affect hormone levels such as testosterone but also be the root of fatigue, weakness and cramp.

Black Pepper / Piper Nigrum (BioPerine)

The extract of piperine, called BioPerine® in the patented form, has been clinically tested in the United States.

This helps increase the absorption of the nutrients that have been orally taken.


Tyrosine is taken for depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), the inability to stay awake (narcolepsy), and improving alertness following sleep deprivation.

It is also used for stress, Parkinson’s disease, Alzheimer’s disease, chronic fatigue syndrome(CFS).

Acetyl Tyrosine is a more soluble form of tyrosine.


Protein is an important building block of bones, muscles, cartilage, skin, and blood. Along with fat and carbohydrates, protein is a “macronutrient,” meaning that the body needs relatively large amounts of it.


It has been touted that Taurine can help mental performance and this is often found in cans of energy drinks that dilute your teeth in to a crumbly mess.

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.

Grape Seed Extract (Vitis Vinifera)

Grapes, or the chemicals within them, especially oligomeric proanthocyanidin complexes (OPCs), have been touted as powerful antioxidants yet in humans there is a real lack of clear evidence that there are any real benefits.

Panex (Korean) Ginseng

This form of Ginseng is the most highly researched.

There’s lots of evidence which suggest cognitive function, mood and immunity is increased, however, although there is evidence for better erections and an increase in testosterone production for infertile men.

It can also improve cognitive function.


One scoop prior to your training session.

A scoop is an acceptable 12g.

This compares well to many of the best pre workout supplements which will offer over 15g.


This has plenty of ingredients that can potentially help me reach my weightlifting goals.

I just hope they are beneficial or nothing that would be particularly useful has been left out of this mix.

Let’s look more closely at the ingredients.

Citrulline can increase nitric oxide and performance when it is dosed in the correct amounts.

BCAA‘s help with building muscle and creating energy, so a particularly good and welcome addition. Especially as you work out you will be tearing muscle fibers. BCAA’s will help repair and recover.

Arginine is theoretically a great ingredient that can open up the blood vessels and arteries to allow a great amount of blood flow.

This helps to transport nutrients to the muscles and organs but also helps transport away and waste products. So a great addition…but more about this later.

Sodium is essential. If we sweat a lot or urinate lots, we need to replace vital salts and minerals as not to lead to a deficiency or under perform.

B12 is proven to help increase energy as well as boost metabolism, so this will help lose fat, too.

B6 can also raise the metabolism and is why it is found in the most effective fat burners. It is also able to help fight fatigue, any lapse of cognitive performance and depression.

Beetroot is known to increase nitric oxide production. This opens up the blood vessels to improve blood flow in order to get more nutrients to the muscles and organs.

Magnesium is another vital mineral that effects nerve and muscle function plus fatigue, be deficient in Magnesium at your peril.

Tyrosine is responsible for improving alertness and fighting fatigue.

Protein is required to help with muscle recovery. It provides the building blocks required to build muscle. It will help ease any muscle pains the day after.

Panax Ginseng is proven to show improvements in cognitive function, improved mood and can also increase testosterone levels.

BioPerine helps your body absorb all of the nutrients more effectively.

So, overall, a great deal of beneficial ingredients included that would help and benefit anyone off to the gym.

However, it isn’t without its flaws.


$45 / £32


While it seems there are very few problems with this pre workout, there’s a few areas that need highlighting.

So let’s start with the couple of ingredients that are not really offering any sort of proven benefit.

Arginine has to be dosed at 5g to be offering the best results. However, this comes in at a woeful 2g per serving.

Citrulline is under dosed by almost 5g!

Taurine has no body of proof that it is effective at improving physical or mental performance.

Grape extract doesn’t hold much benefit, either. Not according to studies, anyway.

This also could have been a more complete supplement if there had been the inclusion of:

  • Caffeine
  • Potassium
  • Coconut water
  • Rhodiola
  • Vitamin C
  • Theanine
  • Zinc

So, while there’s some great ingredients, dose levels have had a negative impact.

I really would have expected Caffeine to be included as well. It’s a shame it hasn’t been.

My Medi Evil Berserker V2 Amino Review Conclusion:

It seems that dose levels play a big part in this supplement, and the problem seems to be around inadequate doses. It is the inadequate doses that have the biggest impact.

It means the effectiveness of Carntine and Citrulline is decimated.

That aside, it does contain other proven ingredients that are going to help you with your workout or sport.

However, ti still omits a raft of other, beneficial ingredients that seems ludicrous that they would not feature here.

Overall, this isn’t totally bad, but it isn’t the greatest, or anywhere near.

Is there anything else to add…?

Well, yes, there is a better product than this that will get you fired up and cause hell in your chosen sport, so it is worth taking a look at 4GAUGE.
