About The Product

Rocket Science is described as a concentrated pre-workout supplement made by Magnum Nutraceuticals. It costs $32.99 for 60 serving containers, with a serving size of 1 capsule per day.

Thats right, unlike other pre-workouts, Rocket Science comes in capsules, not powder form; this doesnt make a difference to the effectiveness of the product, so it isnt a problem.

However, saying that, some people feel that powder gets into your system quicker - but in all honesty, there havent been any studies to prove this.

Anyway, well take you through the nutrient profile of Magnum Rocket Science. But first, well tell you more about the company behind it.

Who are Magnum Nutraceuticals?

Magnum Nutraceuticals are a USA or Canadian based supplements company (their about us section didnt actually specify where they were actually based, so were assuming this).

While there about us section didnt tell us much, were glad that they show off the awards theyve won; not many companies do this anymore, and everyone should be proud of their achievements in the industry.

But one problem we had, was that we didnt learn which year Magnum Nutraceuticals were founded.

Anyway, none of this really makes a difference to the quality of Magnum Rocket Science. So lets see which ingredients have been added inside below….

Magnum Rocket Science Ingredients Explained

Magnum Rocket Science contains 7 ingredients overall, which is a great number to have in 1 supplement; from experience, we know that pre-workouts containing over 10 ingredients are usually under-dosed.

However, one big problem we have, is that every ingredient inside Magnum Rocket Science is part of a proprietary blend (well expand on this below) - add Proprietary blend macro.
Anyway, now that you know why proprietary blends are bad, well take you through each ingredient inside this pre-workout.

By the end of this review, youll know exactly how safe and effective Magnum Rocket Science really is.


Heres Everything You Need To Know:

Caffeine Anhydrous

Caffeine Anhydrous is the best stimulant you can find in supplements. Its proven to be safe and effective when dosed optimally, as its a pure form of caffeine.

However, its never a good idea to add an unknown quantity into a product. But as its inside a proprietary blend, this is exactly what Magnum Nutraceuticals have done.

We always recommend that you consume under 200mg per serving with pre-workout supplements, but youll never find out the exact dosage inside this pre-workout.

For this reason, youre at risk from suffering jittery side effects when taking Magnum Rocket Science.

Ultimately, this is a great example of why we dont like companies using proprietary blends in their supplements.

DiCaffeine Malate

We just mentioned that adding stimulant to a proprietary blend is a bad idea - due to the risk of causing jittery side effects.

Well, DiCaffeine Malate is another stimulant inside Magnum Rocket Sciences proprietary blend.

Basically, we always advise that you only choose pre-workouts containing 1 stimulant; theres no need for any more than this, and consuming under 200mg Caffeine will keep you safe.

Magnum Nutraceuticals have slightly saved themselves, as the whole Java Shock blend only adds up to 133mg - which isnt a bad overall serving of Caffeine to have in a pre-workout.

Still, we would have preferred to not see a proprietary blend in Magnum Rocket Science. But weve noticed that this pre-workout contains more stimulants, which raises your risk of suffering side effects (well explain more below).

Beta Phenylethylamine

This isnt a good addition to Magnum Rocket Science, as its another stimulant; while theres a good mount of Caffeine inside so far, this significantly increases your risk from suffering jitters and energy crashes.

Ultimately, no-one knows the dosage of Phenylethylamine inside Magnum Rocket Science, so we personally wouldnt take the risk here.



L-Tyrosine is a brain booster thats shown to improve your cognition. However, you dont really need improvements to your memory in the gym, and Caffeine offers enough of a boost to your focus to benefit your workout.

For this reason, we dont consider L-Tyrosine to be a necessary addition to any pre-workout. But saying that, it can be a good bonus alongside key nutrient such as Citrulline Malate.

The problem is that there arent many key pre-workout supplements inside Magnum Nutraceuticals.


When consumed with Caffeine, L-Theanine forms a smart-caffeine combo; this enhances the benefits of caffeine (improved energy, focus, strength and endurance), while keeping you safe from side effects.

For this reason, L-Theanine is a great addition to any pre-workout supplement.

However, the big problem is that you dont know the exact dosage of L-Theanine inside Magnum Rocket Science.

Why is this a problem? Because L-Theanine has only shown to work when consumed in bigger dosages than Caffeine.

Ultimately, this means you cant be sure whether L-Thenine will be effective in Magnum Rocket Science; this is a great example of why proprietary blends are a bad thing.


Hordenine is another stimulant that can raise your energy levels. Again, well repeat that theres no need to anymore stimulants in Magnum Rocket Science, and this makes it almost certain that youll suffer from jittery side effects.

Ultimately, we would have preferred to have seen a tried-and-tested nutrient such as Citrulline Malate (which is proven to boost your nitric oxide levels, and therefore your muscle pumps In the gym).


We mentioned that L-Tyrosine was a brain booster thats capable of improving your cognition earlier.

Well, Citicoline is exactly the same, as its also shown to raise your cognition. Again, this isnt a key addition to Magnum Rocket Science, but it can certainly be a useful bonus ingredient here.

Side Effects

The main concern we have with Magnum Nutraceuticals Rocket Science is with the overload of stimulants; when consuming too many stimulants at once, youre almost certain to suffer from numerous side effects, which is never a good thing.

Simply put, as a general rule we advise that you avoid supplements containing more than 1 stimulant in the future. However, there are 4 stimulants inside Magnum Rocket Science.

Anyway, well bullet point the potential side effects from taking this pre-workout below…

Heres the potential side effects of taking Magnum Rocket Science:

  • Jitters (Overload of Stimulants)
  • Energy Crashes (Overload of Stimulants)
  • Anxiety (Hordenine & Beta Phenylethylamine)

Magnum Rocket Science Review Conclusion

We mentioned at the start that Magnum Nutraceuticals advertises this pre-workout as a concentrated pre-workout. And now we can see why, as it contains 4 different stimulants - so theyve tried to make Magnum Rocket Science as strong as possible.

However, consuming more than 1 stimulant in pre-workouts only makes it likely for you to suffer from jittery side effects. Ultimately, this will negatively affect your gym session, which isnt what you want.

Not only that, Magnum Rocket Science is missing most key pre-workout ingredients, such as Citrulline Malate. For this reason, we dont think its very likley that this product will improve your performance in the gym.

Bottom Line

Magnum Rocket Science is more likely to cause side effects than benefit your performance in the gym.

We cant recommend this pre-workout to you, as we believe you can look elsewhere to spend your money wiser (in our honest opinion).
