About the Company

Nutrex is a supplements company that was founded in 2002. They’ve become a respected brand over the years, sponsoring fitness icons like Larissa Reis.

They market a range of products, from fat burners to pre workout supplements.

The Ingredients and How They Work

Outrage has one of the smallest nutrient profiles we’ve seen in a pre workout supplement – but less isn’t always better. But one positive is that none of its ingredients are hidden in any blends, meaning you know the exact doses of each ingredient.

We’ll go through each ingredient inside, to show you whether Outrage delivers on its claims. See for yourself:

HydroMax Glycerol

This is basically branded Glycerol powder. But what’s Glycerol and what does it do?

Well, it’s a liquid that’s almost as sweet as sugar (60%), and it can have a hydrating effect due to its ability to absorb water. But it can dehydrate you if you don’t consume enough water, which can cause side effects.

It’s important to know exactly what this ingredient does, so you can stay safe by increasing your water intake – but those who aren’t aware of its potential to dehydrate can suffer unwanted side effects like dizziness, feeling sluggish, and weakness.

Not only that, the benefit of Glycerol isn’t even a key feature of a pre workout supplement.

Arginine Silicate Inositol

This is a form of arginine that’s bound to silicate – it was created to promote nitric oxide level, leading to muscle pumps in the gym.

However, here’s the bad news – L-Arginine has a poor absorption rate, meaning your body doesn’t make use of it when orally supplemented, so it’s ineffective in a pre workout supplement.

If you’re looking for intense muscle pumps while lifting weights, Citrulline Malate is your best option – Citrulline has a great absorption rate and turns into L-Arginine in your kidneys. Basically, it’s more reliable in delivering muscle pumps in the gym.

This is a cognitive booster, which can be effective in enhancing memory, focus, and reaction time. However, studies have shown that it’s most effective when taken in doses of 100-150mg per kg of bodyweight – meaning a 80kg person would need 8,000mg to experience its full benefits.

Outrage only contains 300mg, so it’s unlikely to deliver great advantages to your gym session. It’s more suited to a Nootropic supplement anyway, as the only benefit it offers is increased cognition – Caffeine offers this, along with key pre workout benefits.


This is the best ingredient in Outrage. It delivers enhanced strength, endurance, and cognition (alertness, focus, reaction time) – all key features of a pre workout supplement.

Nutrex has dosed Caffeine well (175mg). We recommend that you look for a pre workout containing 150-200mg servings of Caffeine, so you experience its full benefits, without side effects like jitters or energy crashes.


This is used in pre workout supplements as it’s believed to be a stimulant and contain fat burning properties. However, there hasn’t been enough studies conducted on Hordenine to prove that it delivers these benefits.

This is worrying, as it also means no-one knows how much you can consume safely – so we can’t say for sure whether the dose in outrage will cause side effects.

Outrage’s ingredients don’t seem to back-up it’s claims. The only key pre workout ingredient contained is Caffeine.

Side Effects

The main concern is that no-one knows what dose of Hordenine is safe, as there’s not been many studies conducted on it.

But another worry is with the Glycerol – if you’re not aware that it can cause dehydration and don’t increase your water intake accordingly. you can experience side effects.

Here is a list of the potential side effects from taking Outrage:

  • Dizziness (Glycerol)
  • Feeling sluggish (Glycerol)
  • Weakness (Glycerol)
  • Unknown side effects (Hordenine)   

Pro’s and Con’s


  • Contains optimal amount of Caffeine


  • Glycerol can cause dehydration if you don’t increase water intake
  • L-Tyrosine is more suited to a Nootropic
  • Arginine Silicate Inositol isn’t reliable in delivering muscle pumps
  • Hordenine isn’t proven to offer any benefits, due to lack of studies conducted on it

Outrage Review Conclusion

After analyzing Outrage’s ingredient list, it doesn’t seem likely to deliver on it’s promises. The only nutrient that’s shown to provide key pre workout benefits, is Caffeine.

We recommend looking for a pre workout containing more key ingredients, such as L-Thenine, Citrulline Malate, and Beetroot Extract.
