The manufacturers call it the most complete pre-workout ever madethis Limitless Pre Workout Review exposes whether that’s the complete truth or complete trash.

Listen up.

Sometimes when we hit the iron, our workouts are less than perfect. Stresses of everyday life can lead our sessions to lack the necessary drive, energy and focus we need.

Not only does this mean ineffectual training—but it also leaves you feeling disappointed and concerned about your commitment.

True words, right?

Yet, guys knocking back the best pre-workouts on the market are experiencing insane levels of determination and power. They push through each set like a rabbit on speed—giving them the ultimate in training sessions and gaining shocking muscles.

This Limitless Pre Workout review examines the incredible story behind this supplement—finally declaring whether it’s a sinner or a winner.

Limitless Pre Workout Review


Let’s get this Limitless Pre Workout review started with a little bit of context.

This product comes from the Muscle Rage stable—a brand that’s a relatively new-kid-on-the-block. Established in 2013 by the British entrepreneur Joe Robson—step by step, it’s trying to break into the competitive world of bodybuilding nutrition.

Their range of products includes the familiar favorites of BCAAs, fat burners, nootropics and SARMS. And, of course, a pre-workout.

But will Limitless leave you hangin’ tough?

The guys behind it have developed a supplement that aims to send your training sessions interstellar—boosting both mental and physical performance.

Muscle Rage states that their pre-workout:

  • Packs in more optimally-dosed compounds that any other in its class.
  • Delivers unparalleled focus.
  • Possesses unrivaled power.
  • Provides unmatched performance.
  • Gives intense focus and limitless energy.
  • Creates massive pumps.

But will this supplement actually make you work out like Donnie Wahlberg or more like Donny Osmond?

How Does Limitless Pre Workout Work?

Its working processes reflect Muscle Rage’s ethos of providing a complete pre-workout supplement.

This formula aims to address the vital areas of focus, energy and stamina to deliver a fully-rounded performance booster.

The compounds in Limitless work by:

  • Elevating nitric oxide production—providing immense pumps and staving off fatigue.
  • Reducing lactic acid build-up—ensuring that acidosis doesn’t curtail your reps.
  • Boosting mental cognition and concentration—the more focused you are, the harder you can push yourself.
  • Improving mood—a depressed bodybuilder is an ineffective bodybuilder.
  • Heightening energy through the inclusion of legal stimulants.

Limitless Pre Workout Ingredients


Just like your automobile—it’s what’s under the bonnet in a pre-workout that counts. A duff engine means a vehicle that lacks the necessary power to drive you at top speed.

Hence, allow me to use this part of this Limitless Pre Workout review to examine the mechanics behind this supplement.

L-Citrulline DL Malate

A freakingly remarkable ingredient to begin with.

If you demand competition-worthy pumps that Ronnie Coleman would be proud of—you need citrulline.

Here’s the biology.

When you consume citrulline, your body metabolizes it into arginine. This compound elevates the production of nitric oxide.1

This gas acts as a vasodilator—allowing more blood to flow into your muscles. It results in massive pumps—the instant bodybuilding rewards that drive your determination.2

In addition to these visible returns, citrulline will also:

  • Heighten the rate of muscle protein synthesis—enabling you to gain mass more quickly.3
  • Reduce blood pressure levels.4
  • Elevate the creation of human growth hormone—a massive anabolic that boosts muscle growth.5
  • Lift your oxygen uptake to enhance training performance.6


Feeling your muscles burn during training can be an immense motivator. You know you’re pushing your body hard and are going to witness some seriously impressive gains.

But, if that burn becomes pain—it can ruin your sessions.

As you work out, lactic acid builds up—eventually leading to acidosis. Not only is this highly uncomfortable, but it also reduces performance and can lead to complete fatigue. You may have all the determination in the world—but your muscles aren’t going to work.7

However, consuming beta-alanine can prevent these training-destroying effects—hence it’s pleasing to see it included in this Limitless Pre Workout review of the ingredients.

Beta-alanine elevates your body’s production of carnosine—a protein which cuts down muscle acidity and lowers the chance of workout failure.8 9 

There’s more.

Research shows that beta-alanine can also lower oxidative stress—reducing inflammation and improving recovery times so you can hit the gym again sooner.10

Alpha GPC

It’s not all about the muscles.

Schwarzenegger said,

The mind is the limit. As long as the mind can envision the fact that you can do something, you can do it, as long as you really believe 100 percent.

Alpha GPC (glycerylphosphorylcholine) elevates brain activity, boosting focus and attention—enabling you to concentrate 100 percent on your training.11

Caffeine Anhydrous

If you wanted, you could chug back a couple of espressos before your workouts—but you wouldn’t be taking the purest form of caffeine.

Caffeine anhydrous has had all unnecessary compounds and liquid removed—delivering you with nothing but energy-boosting and focus-enhancing returns.12

Eria Jarensis

This orchid extract supposedly boosts mood and focus—possibly as it contains the alkaloid N-dimethylphenethylamine.

However, there’s little scientific evidence to show it has any effect.13

Di-Caffeine Malate

Another caffeine compound in addition to the anhydrous form I mentioned earlier in this Limitless Pre Workout review.

By bonding malic acid with caffeine—it delivers fewer digestive and crashing issues that this stimulant may sometimes induce.


Naturally occurring in green tea, theobromine boosts mood, increases alertness and can lower blood pressure.14

Huperzine A

This moss-extracted nootropic elevates mental cognition, memory and training focus.15

Black Pepper Extract

Your supplement may contain the most powerful and scientifically proven pre-workout compounds in the world—but if your body doesn’t use them effectively, they’re pointless.

Hence, I welcome black pepper extract in this Limitless Pre Workout review of the ingredients.

Black pepper extract improves the bioavailability of all the other compounds—boosting their absorption rates and ensuring you reap the maximum returns.16

But it doesn’t end there.

Black pepper can also:

  • Elevate mood—by increasing your dopamine levels.17
  • Lower inflammation thereby improving recovery times.18
  • Support the immune system.19
  • Boost the metabolization of carbohydrates and fats—assisting with weight loss.20

Other ingredients: citric acid, natural and artificial flavors, acesulfame-k and silicon dioxide.

Limitless Pre Workout Ingredients Breakdown

I’ve illustrated above in the Limitless Pre Workout review of the ingredients that the vast majority are backed by science for their performance-enhancing effects.

Yet, is it enough?

To put Limitless to the ultimate test—I’ve compiled an ultimate pre-workout compound checklist. These are the essential ingredients that any supplement claiming to be a complete training booster should contain.

Here’s how Limitless performs:

  • Caffeine.
  • Beta-alanine.
  • Citrulline malate.
  • ✘L-norvaline.
  • ✘Betaine anhydrous.
  • ✘L-theanine.
  • ✘Acetyl l-carnitine.
  • ✘Green tea leaf extract.
  • Black pepper extract (Bioperine).

Containing just four of the top nine pre-workout ingredients—it’s rather disappointing.

Let me give it a little credit in this Limitless Pre Workout review.

Of the proven compounds it does contain—the doses are substantial. Six grams of citrulline will undoubtedly deliver some impressive pumps. Furthermore, the 3.2 grams of beta-alanine should stave off any fatigue-inducing lactic acid.

Additionally, while it doesn’t contain green tea leaf extract, Limitless does include the mood-boosting theobromine—found in green tea. What’s more, each ingredient in Limitless is quantified—there are no secretive proprietary blends hiding embarrassing underdoses.

The problem lies in the omissions.

Any supplement claiming to be the complete pre-workout should include the power-elevating betaine, the recovery-boosting carnitine and the focus-enhancing norvaline.21 22

Limitless Pre Workout Side Effects

For most users, this supplement shouldn’t cause any severe or unwanted side effects. All the ingredients are natural—we’re not talking about heart-exploding or liver-wrecking steroids.

However, there are some possible adverse reactions that I need to mention in this Limitless Pre Workout review.

Firstly, it’s quite stimulant-heavy.

With 250 mg of caffeine anhydrous and 100 mg of di-caffeine malate, it could be too intense for some guys. This may result in the following reactions:

  • Nervousness.23
  • Agitation.
  • Interrupted sleep or insomnia.
  • Stomach upsets.
  • Diarrhea.

Furthermore, beta-alanine may cause paresthesia—a strange, tingling sensation. This is nothing to worry about and usually subsides after a couple of hours—although it can be a little annoying.24

Finally, like caffeine, theobromine may induce irritability and headaches.25

Limitless Pre Workout Before After Results

We’ve looked at the theory in this Limitless Pre Workout review—but what about in the real world?

To see how powerful this supplement is—I researched genuine customer experiences with this pre-workout. These are some typical examples of what guys are saying:

“A powerful pre-workout. I have had to dial it back a bit, though, as I was starting to get jittery using it on every workout. Packs a very mean punch but does affect sleep a bit if taken too late in the day.”


I don’t feel a super pump like others I tried in the past.”


“It does what it says, but for how long? I can’t take it every day because it’s quite high in caffeine content. The energy is high, but I think its short term only. It lasted me 30-45 minutes.”


“It may just be me, but after about four hours after I’ve taken it, my body is so tired, and I’m falling asleep. Perhaps that’s maybe due to the hard workout I’ve had from the pre-workout, or maybe it’s a crash from it I don’t know.”


“It’s alright. It gives me a bit of a buzz, and I feel like I’m ready to train hard. It doesn’t seem to last long, though. Halfway through my workouts, I’m dropping off again. I would up the dosage, but with so much caffeine, I know it’s not a good idea.”

Limitless Pre Workout Review Conclusion

Unfortunately—this supplement has its limits.

Let me start with at least some positives.

The formulation is solid. Virtually all of the ingredients are scientifically-proven performance enhancers. Unquestionably, taking this product will give some benefits to your workouts—elevating your pumps and increasing your focus.

However, it’s just not enough.

Missing key pre-workout ingredients such as theanine, carnitine and betaine means that this supplement lags behind the serious players in the market. Furthermore, the heavy caffeine content may be too intense for some users.

The bottom line in this Limitless Pre Workout review:

If you want to go beyond your limits—choose an alternative pre-workout with more proven compounds.
