There have been a lot of rumors that this pre-workout has been banned—this Mr. Hyde Nitrox pre-workout review will illustrate it’s only half the story.
Mr. Hyde was once touted as the most powerful stimulant-packed pre-workout on the market—delivering powerful energy bursts and supercharging training sessions.
And, I know you’ll agree, that’s what we’re all after, right?
However, with gossip about it being banned and the formulation being changed—it’s a concerning scenario. Is, or was it, danger
This article will make it all clear.
In this Mr Hyde pre workout review I’ve put together everything you need to know about this supplement—if it’s effective, how it works, and whether it’s still available today.
Do you want the crazy story behind this supplement? Then read on!
About Mr. Hyde Nitrox
Let me start off this Mr. Hyde Nitrox pre-workout review with a little detail.
Mr. Hyde is a pre-workout designed to take energy, strength, and recovery to the limits. Created with the serious bodybuilder in mind—its formula is angled towards massively improving workout performance—delivering faster mass-gaining rewards.
When Mr. Hyde pre-workout was introduced by well-known supplement manufacturer ProSupps, it rapidly gained a massive following. Half through clever marketing and a half through a crazy stimulant-based formulation—guys couldn’t get enough of this stuff!
But, don’t get too excited.
The original Mr. Hyde wasn’t as incredible or innovative as it first appeared—its main power coming from a massive dose of 419 mg of caffeine.
Yet, as you will soon discover in this Mr. Hyde pre-workout review, this first incarnation was withdrawn. This led ProSupps to reformulate the pre-workout—into what could be called Mr. Hyde 2.0.
However, whether guys missed the original formulation, or they just didn’t trust the product any more—ProSupps then discontinued Mr Hyde 2.0 and replaced it with their Signature series pre-workout—which bears little resemblance to the first two products. They also have Mr. Hyde Nitrox and Mr Hyde Icon for sale.
In this Mr. Hyde pre workout review, I’ll concentrate on the Mr. Hyde Nitrox.
Just one more thing:
How Does Mr. Hyde Nitrox Pre Workout Work?
Mr. Hyde Nitrox pre-workout concentrates on three areas of training—using its own distinct compounds. To give credit where it’s due, in each of these “matrices” as they call them—all ingredients are quantified.
- Strength Matrix—ingredients angled toward boosting endurance, raising blood flow to the muscles, and increasing pumps.
- Caffeine Matrix—three types of caffeine, giving both short and long-term energy boosts.
- Intensity Matrix—compounds that aim to stimulate the brain and increase focus.
However, you can give your matrices whatever names you want—it doesn’t mean they’ll deliver the returns they promise.
Let’s get down to the serious detail in this Mr. Hyde pre-workout review—is it as good on the inside as it appears on the outside?
Mr Hyde Nitrox Ingredients
As you can see from Mr. Hyde’s Nitrox pre-workout label, it includes 13 ingredients in three separate matrices.
Let’s look at the key components of each for the next part of this Mr. Hyde pre workout review.
Additionally, it includes the nitric oxide boosting l-citrulline and nitrosigine. These ingredients act as vasodilators—opening up the blood vessels, allowing increased delivery of oxygen to the muscles—improving strength and stamina.3 4
However, despite containing proven ingredients—it’s not as powerful as it first appears.
Let me explain.
Firstly, while creatine is a potent endurance enhancer—it’s better treated as a separate daily supplement—building up your stores with a few initial days of loading and then maintaining those levels. There’s little benefit to taking immediately before working out.
Secondly, citrulline and nitrosigine are powerful nitric oxide boosters—but only when taken in sufficient doses. This pre-workout contains one gram—the best pre-workouts will include a more effective dose of around six grams.
As you can see from Mr. Hyde pre-workout label, this is a stim-heavy formulation.
- Caffeine anhydrous (300 mg)—caffeine with all the water content removed, meaning it raises blood levels quicker than standard types.5
- Dicaffeine malate (70 mg)—it’s thought that this compound (often referred to by the brand name Infinergy), causes fewer stomach issues and can reduce the “crash” experienced post-caffeine consumption.
- Caffeine citrate (50 mg)—a synthetic, lab-produced form, consisting of caffeine anhydrous, sodium citrate dihydrate, and citric acid monohydrate.
But be very, very, careful.
A 2017 study on this formulation, in this dose, considered it to be unacceptably high in caffeine—stating it will “pose a serious public health risk to consumers”. 6
As you will see later in this Mr. Hyde pre-workout review—many users have witnessed these serious effects.
Designed to increase focus, it includes:
- Choline bitartrate—shown to improve cognition and enhance brain-muscle coordination.7
- N-Acetyl tyrosine – shown to enhance mental function and focus
Other ingredients: L-theanine, theacrine, (GABA) and Yohimbe.
The bottom line:
As an endurance enhancer, it’s limited. Yet as an energy booster it’s very powerful but, as the studies indicate, possibly to the point of danger. The focus raising ingredients are ok, but may need more research.
Let me tell you something.
The best pre-workouts are phenomenal and should be part of your training regime—but without the right ingredients, they’re pointless.
Hence, for this Mr Hyde pre workout review, I’ve put together everything you should look for in a serious training booster.
Here’s how Mr Hyde compares:
- ✓Beta alanine
- ✓Citrulline malate
- ✘Betaine anhydrous
- ✘Black pepper extract (Bioperine)
Out of the seven powerful pre-workout ingredients—Mr Hyde only contains three.
And that’s not great.
Furthermore, of the three it does contain, I’d consider citrulline to be underdosed, and the caffeine content to be too high.
Mr Hyde NitroX vs Mr Hyde
I want to make something clear in this Mr Hyde pre workout review:
Mr Hyde isn’t the same as Mr Hyde NitroX.
They’re similar—but they have a few important differences. Let’s look at them in this Mr Hyde NitroX vs Mr Hyde comparison.
- Mr Hyde NitroX pre-workout has dropped the agmatine ingredient and replaced it with arginine silicate—a nitric oxide booster that may be more effective (even though it’s still underdosed).8
- If the caffeine dose in Mr. Hyde wasn’t enough—they’ve increased it by a further 1 mg in Mr. Hyde NitroX, and also included citric acid in the caffeine blend, although I cannot find any basis for its inclusion.
- In the Mr. Hyde NitroX intensity matrix, hordenine and n-methyl l-tyramine have been dropped in favor of the concentration-boosting theanine, stress-reducing n-acetyl-tyrosine, and fatigue-boosting theacrine.9 10 11
So, Mr Hyde NitroX vs Mr Hyde in brief:
In my opinion, despite the claim that Mr Hyde NitroX is more powerful than the original Mr Hyde, the only improvement I can see is that it may have more beneficial effects on focus—nothing else.
Furthermore, the online Mr Hyde review and remarks are not very impressive.
Mr Hyde Banned
The question you want answering in this Mr Hyde pre-workout review—was Mr Hyde Pre workout banned?
The answer is… sort of.
In effect, there was a Mr Hyde pre workout recall. It was withdrawn from sale by ProSupps under the direction of the US Food and Drug Administration (FDA).
Surprisingly, it wasn’t down to its high levels of caffeine but a more innocuous ingredient—picamilon.
Listen to this:
It’s a psychoactive drug which inhibits anxiety.14
Not surprisingly, the FDA decided that it wasn’t a vitamin, mineral, herb, or amino acid and therefore had no place in a dietary supplement. In 2015, it sent letters to suppliers stating they must remove products that included this ingredient.15
So, ProSupps removed Mr Hyde from sale.
It was then made available with a different formulation, which we have looked at above—without the picamilon ingredient. Although, this too was discontinued and replaced both with Mr Hyde NitroX and the Mr Hyde Signature Series pre-workout.
The bottom line.
Was Mr. Hyde Pre workout banned?
The ingredient picamilon was—and the original Mr Hyde contained it—so there was a Mr Hyde pre-workout recall.
With the massive dose of caffeine, it’s unsurprising that some guys have suffered side effects.
After researching numerous bodybuilding forums for this Mr Hyde pre workout review, the most commonly experienced were:
- Stomach upsets.
- Hot flushes.
- High blood pressure.
Furthermore, beta-alanine is known to cause “itching”. Technically known as paresthesia, it’s annoying but not harmful, and passes within a couple of hours.

Many customer testimonials have one thing in common—awful caffeine-induced side effects.
