My USN Hyperdrive Extreme PRE2 Pre Workout Review

My USN Hyperdrive Extreme PRE2 Pre Workout Review First Look:

It is Sunday evening, I have been painting different rooms in my house all weekend and thankfully I am hangover free today.

That much cannot be said for Saturday morning when I felt like rhinoceros had taken a great big dirty shit inside my head.

However, last night was a fairly late one, I went over to see my girlfriend in the evening and we both fell asleep on the sofa, when we woke up and I went home I then couldn’t get straight to sleep.

Then I was up fairly early this morning to have breakfast with a buddy and then spent a shit load of cash on supplements.

One of those supplements is this pre workout from USN called HYPERDRIVE EXTREME PRE2.

I glanced over the ingredients panel when in the store and almost stared in to disbelief…there are some great ingredients included.

This was shaping up to be an excellent supplement for me to have before I hit the weights this evening.

Unfortunately I had a kitchen to paint first and a shit Sunday dinner to cook, but once those minor hindrances were out of the way I mixed a scoop of 10g as instructed before my gym session.

It mixed well and tasted great…thinks were just getting even better…or were they..?


RELATED: We’ve tried and tested the best pre-workout supplement HERE!

Vitamin B6 – Comprising three chemically distinct compounds pyridoxal, pyridoxamine, and pyridoxine, is involved in the regulation of mental function and mood.

Vitamin B6 is also an essential homocysteine re-methylation cofactor, and deficiency is associated with increase in blood homocysteine levels.

Homocysteine is a risk factor for cerebrovascular disease and may also have directly toxic effects on neurons of the central nervous system.

Neuropsychiatric disorders including seizures, migraine, chronic pain and depression have been linked to vitamin B6 deficiency.

L-Citrulline – 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.

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 C – Widely hailed for its benefits. It can help protect the testes fro stress and therefore preserve testosterone levels. Being an anti-oxidant helps with blood flow too.

Magnesium – Research into magnesium supplementation also increased testosterone production in men.

Zinc – An aphrodisiac and Testosterone Booster.

Zinc is also very important for the functioning of the enzyme, hormone, and immune systems.In very high doses, zinc can act as an aromatase inhibitor and reduce estrogen levels.

It is also a potent antioxidant and can provide benefits for prostate issues.

Vitamin D – A great Testosterone boosting vitamin that must be taken advantage of to trigger further production of Testosterone in your body.

However, there are two types of Vitamin D. There’s calciferol (vitamin D2) and cholecalciferol (vitamin D3) – we are only interested in cholecalciferol which is D3; this is the type our skin synthesizes from the sun and becomes a hormone which results in the increases in our testosterone.

Research by the US Library of Medicine has shown that testosterone productions are increased with Vitamin D3 supplementation.

There’s a plenty of articles I have written covering the benefits of D3 you can read about, herehere and here.

Creatine – A well regarded supplement overall!

Supplementation increases creatine storage and promotes a faster regeneration of adenosine triphosphate between high intensity exercises.

These improved outcomes will increase performance and promote greater training adaptations.

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.

It is also found in Instant Knockout which is the best fat burner available at present.

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.

D-Aspartate, DAA – D-aspartic acid is one of two forms of the amino acid aspartic acid. The other form is L-aspartate. The benefits of D-AA are specific to it, and do not extend to aspartic acid or L-aspartate. D-AA can be used as a testosterone booster for infertile men, and by athletes as a temporary booster.

D-AA works in the central brain region to cause a release of hormones, such as luteinizing hormone, follicle-stimulating hormone, and growth hormone. Importantly, unlike some pro-hormones and steroids, it does not raise estrogen levels.

A dose of 2000-3000mg is required.

Calcium is added to help with solubility, thus we get Calcium D-Aspartic Acid.


10g mixed with water before training.

This does not compare particularly well to many of the best pre workout supplements which will offer over 15,000mg.

The taste was a nice and quite sharp. I really enjoyed it.

It did make me fart really bad though, I stunk the gym out. I almost asphyxiated down there…

Benefits & Effects:

Caffeine is a great stimulant that can effect the CNS which controls muscle and heart stimulation.

Vitamin D and Vitamin C is great for testosterone and Vitamin C is good for blood flow which will help get nutrients and oxygen to organs and muscles.

Speaking of which, the inclusion of D-Aspartic Acid, Zinc and Magnesium is also good for keeping testosterone levels elevated which is great for strength, energy and muscle building.

B6 has cardiovascular benefits and B12 can help provide the energy required to exercise.

Creatine is known throughout the supplement world as being a very effective ingredient to help build muscle and strength. It too, can raise testosterone levels.

Citrulline is great for increasing nitric oxide and increasing performance.

How Did It Feel?

I didn’t feel anything, not even the Beta-Alanine.

This really got me thinking…

Nearly every ingredient is excellent, so why did nothing happen..?



I was surprised that I did not feel the Beta-Alanine, however, even if I had felt it, it is not proven to offer any performance benefits anyway.

However, this is the least of the issues concerning this pre workout supplement…

The doses for almost every ingredient is criminally low.

Okay, so it is not actually criminal, but they are too low to have any real effect on performance.

For instance, B6, B12, Magnesium and Zinc is just so far below the offerings we find for testosterone boosters they may as well not be there.

This is the same for Vitamin D, which then brings me on the the next issue with the Vitamin D that is included, it is D2 not the more effective D3 commonly found in the most effective testosterone booster supplements.

Creatine is at a level whereby if the dose was doubled it would be more beneficial and this is the same for D-Aspartic Acid, because from just one serving it is at least 500mg too low.

However, there would be no hope for Citrulline which would need to be dosed twelve times more to reach a level where it would offer any performance benefits.

If you increased the serving by 12 the amount of Caffeine would probably burst your heart or at least send you in to a killing frenzy.

At much higher doses the Beta-Aline would also probably feel like someone is actually nailing you alive to a crucifix.

USN should really just increase the amount of almost all of the ingredients instead so we do not have to go through a ritual of self torture just before we hit the gym .

My USN Hyperdrive Extreme PRE2 Pre Workout Review Conclusion:

On the very surface this looks like a beneficial pre workout that can also double up as a testosterone booster.

Sure, it is missing some other vital ingredients to make it a more accomplished pre workout, but it was impressive to see.

However, then, when we scratched the surface a little more, it opened up a whole number of failings.

These failures are based around doses.

10 grams i not enough, especially when you have to consider what the other, effective and beneficial pre workout supplements offer.

Overall, there’s lots of theoretically beneficial ingredients, however, they have not been dosed high enough to offer any real benefit.

It also omits many proven ingredients that are present in many of the best pre workout supplements.

This was absolutely clear when I tested it for my gym session I felt no effects at all. Absolutely nothing.

Therefore, as it is missing the following ingredients and not being dosed adequately I would not suggest that this pre workout from USN is worth bothering with:

  • Coconut water
  • Potassium
  • Theanine
  • Rhodiola
  • Carnitine
  • Beet

There is a better product than this that will get you fired up and cause hell in your chosen sport.
