MuscleTech Shatter SX-7 Revolution container for a leanbulking review

About The Product

Shatter SX-7 Revolution is a pre-workout supplement made by MuscleTech. It costs $69.99 on (at the time of writing this review) for 50 serving containers.

This is quite alot of servings, so it’s not as expensive as it looks – Shatter SX-7 Revolution is very similarly priced to other premium fat burners serving to serving.

Anyway, we’ll analyze MuscleTech’s pre-workout after telling you about this company (for those new to supplements).

Who are MuscleTech? 

If you know about supplements, then you’ll know about MuscleTech; it’s one of the biggest sports nutrition brands in the industry.

They’re probably best known for their ‘Hydroxycut’ line of fat burners (we’ve also reviewed their Hydroxycut Hardcore Next Gen if you’re interested).

But they’re also building a name for themselves in other areas. This is what gained our attention with Shatter SX-7 Revolution; we’re interested in seeing whether this can help them dominate the pre-workout market too.

Shatter SX-7 Revolution Ingredients Explained

When looking at Shatter SX-7 Revolution’s ingredient list, we’re happy that this pre-workout doesn’t contain any proprietary blends (meaning you can see the exact dosages of each ingredient inside).

For this reason, we’re able to accurately analyze its nutrient profile for you – and show you how effective Shatter SX-7 Revolution really is.

Here’s Everything You Need To Know:


Everyone has mixed opinions about Beta-Alanine; it’s shown to improve your muscular endurance, but causes a side effect called paresthesia.

What’s paresthesia? Answer: a tingling and itching sensation on the skin of your face and body. It’s distracting when you’re trying to focus in the gym, so personally, we avoid Beta-Alanine.

However, we’ll never completely criticize a pre-workout just because it contains this ingredient (as we mentioned, it can be beneficial).

For this reason, we won’t advise you to stay away from Shatter SX-7 Revolution because of Beta-Alanine. But personally, it’s something that puts us off.


L-Citrulline is a great addition to any pre-workout supplement.

Although we prefer Citrulline Malate (L-Citrulline mixed with Malic Acid, which improves your muscle pumps and strength in the gym), L-Citrulline is still beneficial on its own too.

However, when taking L-Citrulline, studies have shown that a dosage of 3,000mg is needed for it to work. As you can see from Shatter SX-7 Revolution’s ingredient list, this pre-workout only contains 1,500mg (meaning it’s not likely to work here).

We mentioned that we prefer Citrulline Malate, so if you’re looking for this, you’ll need at least a 6,000mg dosage for it to be effective.


From good to bad…Betaine is one of the ingredients we always avoid.

Here’s why; Betaine is a useless ingredient that hasn’t shown to offer any benefits in studies. But it causes a strange side effect – fishy smells from your breath and sweat.

We don’t want to smell like a fishcake while pumping iron in the gym. And as it doesn’t do anything to improve our workouts, there’s no reason why you should suffer this side effect.

The only positive here, is that MuscleTech hasn’t added Betaine into a proprietary blend, so we do credit them for that.


Taurine is an organic acid containing sulfur (not bull-urine like some think it is).

Another myth we’ll break now; Taurine hasn’t shown to boost your energy levels in any studies (but some believe it does, as it’s inside energy drinks).

The real reason why Taurine is inside energy drinks – it’s able to calm you down slightly while taking big dosages of caffeine (but it won’t stop you from suffering jitters or energy crashes).

Although Taurine has shown to reduce cramping, you can still achieve this benefit simply by keeping yourself hydrated in the gym. So it’s not really needed in Shatter SX-7 Revolution.



Everyone knows what Caffeine is; it’s consumed in tea & coffee everyday, around the world!

So you can be safe knowing it’s safe – when consumed in dosages under 200mg per serving. So what does it do? Answer: it’s able to improve your strength, endurance, focus and energy levels in the gym (all key benefits to enhance your workout).

MuscleTech has done well here by adding a good 175mg serving of Caffeine. This would have kept you safe from jitters and energy crashes, but they’ve also added another stimulant (which we’ll analyze below).


Theacrine is another stimulant that’s believed to offer similar benefits to Caffeine. However, this is a bad thing – as MuscleTech has already added enough Caffeine in Shatter SX-7 Revolution.

For this reason, you have a higher chance of suffering from jitters and energy crashes here.

Lion’s Mane 

This is a mushroom also known as Yamabushitake; it’s shown to boost your cognition, which is why it’s used in Nootropic supplements.

However, it’s not as useful in pre-workout supplements – Caffeine offers enough boost to your focus in the gym, so Lion’s Mane isn’t needed here.

Guayusa Leaf 

We’ve not seen this ingredient in pre-workouts before Shatter SX-7 Revolution. It’s basically the leaves taken from the Guayusa tree, but what isn’t good, is that it’s another stimulant.

We mentioned that there’s already an overload of stimulants with Caffeine & Theacrine both inside MuscleTech’s pre-workout. But Guayusa added makes it almost certain that you’ll suffer from jitters and energy crashes.

Yohimbe Extract 

Yohimbe Extract is by far the worst ingredient inside Shatter SX-7 Revolution. It’s a subset of Yohimbine (which isn’t good, since this has been banned in numerous countries after causing side effects).

Simply put, Yohimbe Extract has also shown to cause potentially harmful side effects – so this is something we advise that you avoid.

In fact, we believe this will also be banned in the future.


Side Effects

We probably sounds like we’ve been quite harsh in this review. But you can’t argue with us after reading our analysis of Shatter SX-7 Revolution’s nutrient profile.

Simply put, MuscleTech has added an overload of stimulants (3 different sources; Caffeine, Theacrine & Guayusa Leaf) – this makes it almost certain that you’ll experience side effects such as jitters and energy crashes.

Not only that, Betaine will make your breath and sweat smell fishy. And Yohimbe is likely to cause numerous side effects, which we’ll bullet point below.

Here’s the potential side effects from taking Shatter SX-7 Revolution: 

  • Jitters (Overload of stimulants)
  • Energy Crashes (Overload of stimulants)
  • Fishy smells in breath and sweat (Betaine)
  • Anxiety (Yohimbe Extract)
  • Nausea (Yohimbe Extract)
  • Stomach Ache (Yohimbe Extract)
  • High Blood Pressure (Yohimbe Extract)

Shatter SX-7 Revolution Review Conclusion

MuscleTech are very well respected in the supplements industry. But they haven’t done a great job when formulating Shatter SX-7 Revolution.

Don’t get us wrong, they might have purposefully made this pre-workout to be ‘powerful’ by adding 3 different sources of stimulants in big dosages. However, this only makes it likely for you to suffer from jitters and energy crashes.

Personally, we prefer pre-workouts that contain under 200mg per serving of Caffeine; this ensures that you benefit from energy boosts in the gym, without any jittery feelings or feeling exhausted halfway through your gym session.

Not only that, we always stay away from supplements containing Yohimbe; this ingredient is believed to promote fat loss, so it’s not even needed in Shatter SX-7 Revolution anyway.
