About Mr Hyde NITRO X
Mr Hyde NITRO X is Pro Supps’ newest addition that was released in 2017. It’s an expensive product, at the price of $35.99 for 15 servings, and $59.99 for 30 servings.
As a result, Mr Hyde NITRO X is priced to compete with the premium pre-workouts on the market; so it’ll be interesting if it can beat any of our top rated pre-workout supplements this year.
Before we take a look at the ingredients inside Pro Supps’ pre-workout, we’ll tell you a bit about this company below.
Who are Pro Supps?
Pro Supps are a USA-based supplements company. They’re well known for their pre-workout supplements – Mr Hyde and Mr Jekyll, which have become very popular in the industry.
As a result, Pro Supps have decided to release these new supplements, Mr Hyde NITRO X. We’re expecting big things, as this is supposed to be a direct improvement on their last product.
Let’s see whether it is.
Mr Hyde NITRO X Ingredients Explained
Mr Hyde NITRO X contains 13 main ingredients that we’ll be analyzing for you in this section. But we’ll point out that this is a HUGE number of ingredients to have in 1 product.
We prefer pre-workouts that contain less than 10 ingredients, as they’re usually contain better dosages of ingredients inside. After a quick look at Mr. Hyde NITRO X’s nutrient profile, we can see that Pro Supps has under-dosed L-Citrulline…which proves our point.
Also, we have to point out that Mr Hyde NITRO X contains a proprietary blend…
Anyway, we’ll take you through each ingredient inside Mr. Hyde NITRO X – to show you how effective this pre-workout really is.
Here’s Everything You Need To Know:
This always splits opinions on bodybuilding forums; this is because Beta-Alanine can enhance muscular endurance, but also cause a side effect called paresthesia.
Paresthesia is a tingling and itchy sensation on your face and body – personally, we find this side effect very distracting when we’re trying to focus in making gains in the gym…
For this reason, we try to avoid pre-workouts that contain Beta-Alanine. But we do acknowledge that others might not find paresthesia as bad as us, so we never criticize a supplement just because it contains Beta-Alanine.
However, we will say this; Creatine Monohydrate offers the same benefit, without causing any side effects, so we’d choose this everytime.
Many companies have started adding different forms of Creatine – to try and produce the ‘most up-to-date- product. However, we believe there’s no need to fix something that’s not broken. And Creatine Monohydrate has proven to be both safe and effective since the 1980’s.
For this reason, we prefer to see Creatine Monohydrate in pre-workout supplements.
Not only that, as less is known about Creatine Nitrate; this means no-one is 100% sure whether it’s safe or effective. It’s always better to choose the tried-and-tested ingredients.
This is basically a mixture of Arginine and bound to silicate. All you need to know that this ingredient hasn’t shown to be effective in any studies – making it an unreliable product.
This is because Arginine has a poor absorption rate, so any ingredient that it’s mixed with will won’t work.
We’re not sure why Pro Supps has chosen this mixture of Citrulline and Aspartate. L-Citrulline, on its own (or as Citrulline Malate) is a key pre-workout ingredient, as it’s shown to promote muscle pumps.
However, there hasn’t been any studies to prove that this mixture works – making it an unreliable ingredient. Not only that, Citrulline’s been under-dosed here anyway; for L-Citrulline to be effective, you need dosages of at least 3,000mg (for Citrulline Malate, the optimal dosage is 6,000mg).
For this reason, Citrulline Aspartate won’t do much here.
This is the safest and best stimulant you can find in pre-workout supplements. Basically, studies have proven this – and you should know, as it’s consumed everyday in tea & coffee.
However, if you’ve ever consumed too much coffee before, you know it can cause jitters and energy crashes. Well, it’s the same when added into supplements.
For us, under 200mg Caffeine offers benefits without causing side effects. However, anything over 200mg can cause jitters or crashes – which is why we try to avoid pre-workouts containing this amount of Caffeine.
Unfortunately, Mr Hyde NITRO X contains 300mg Caffeine; meaning it might cause you side effects (unless you regularily drink more than 4 cups of black coffee per day).
The bottom line is, we prefer pre-workouts to contain less than 200mg Caffeine per serving – to stay safe from jitters or energy crashes.
This is another form of Caffeine. All you need to know is that this is a bad thing; Mr Hyde NITRO X already contains 300mg of Caffeine, so adding more puts more people at risk from jitters and energy crashes.
For this reason, we recommend that you avoid pre-workouts that contain more than 1 source of stimulants – to stay safe from side effects.
Caffeine Citric Acid Blend
This is a proprietary blend that’s contained inside Mr Hyde NITRO X. Basically, you’re told that the overall quantity of this blend is 50mg, but you’re not shown the exact dosage sof hte ingredients inside.
Anyway, it’s the same problem here as the Di-Caffeine Anhydrous; there’s already an over-dose of Caffeine in Mr Hyde NITRO X – so this blend makes it almost certain that you’ll suffer from side effects.
Even those that are tolerant to Caffeine will have their heads blown off – and suffer from jitters and energy crashes here.
Choline is one of the worst pre-workout ingredients you can find. Here’s why; it offers no benefits to improve your gym session, but causes a side effect.
What side effect does Choline cause? Answer: fishy breath and sweat.
This is something you want to avoid – no-one likes smelling like they have an STI…Personally, we don’t anyway.
The bottom line is this; Choline is a useless ingredient that makes you smell fishy.
Theanine is usually a key pre-workout ingredient, but Mr Hyde NITRO X contains wayyy too much Caffeine for it to work.
Basically, Theanine enhances the effects of Caffeine – allowing companies to add smaller dosages of it, while offering you the same benefits as a higher dose.
This means that you’ll be safe from side effects while enjoying benefits such as; improved focus, strength, energy and endurance. However, as there’s an over-dosed of Caffeine in Mr Hyde NITRO X, there’s no stopping you from suffering from jitters and energy crashes.
Tyrosine is a ‘brain-booster’ that’s shown to offer enhanced cognition when added into supplements. However, when Caffeine is dosed under 200mg per serving, it offers enough of boost in focus to benefit your gym session.
For this reason, Tyrosine isn’t needed in pre-workouts that contain Caffeine. But it’s a key ingredient inside Nootropic supplements.
This is a stimulant that’s believed to offer similar results to Caffeine. However, as it’s a fairly new ingredient, there isn’t much known about it – meaning it’s not 100% certain whether its safe or effective.
For this reason, we’re sticking with Caffeine for now. But we’ll be keeping an eye out for future studies on Theacrine.
Also known simply as GABA, it’s believed to enhance your human growth hormone (HGH) levels and promote brain health. However, no study has proven whether it’s actually effective.
For this reason, GABA is an unreliable ingredient in Mr Hyde NITRO X.
Yohimbe is on our ‘blacklist‘ of ingredients to avoid for one reason – it’s commonly reported to cause harmful side effects.
Basically, it contains the same compounds as Yohimbine (which has been banned in both the UK & Canada for causing harmful side effects). The reason why Yohimbe is used instead, is because it’s believed to be safer, but it isn’t.
For this reason, we can’t recommend any product that contain Yohimbe – and none of the pre-workouts on our top 3 contain this ingredient.

There are 4 things that can cause side effects in Mr Hyde NITRO X; Beta-Alanine, Choline, the HUGE amount of Caffeine (over 300mg per serving) and Yohimbe.
We’ll quickly take you through what each ingredient can cause…Beta-Alanine can cause paresthesia (tingling and itching on your face and body).
Not only that, Choline can cause your breath and sweat to smell fishy. The HUGE amount of Caffeine will almost certainly cause jitters & energy crashes, and Yohimbe has been reported to cause numerous side effects, which we’ll take you through below.
Here’s the potential side effects from taking Mr Hyde NITRO X:
- Paresthesia (Beta-Alanine)
- Fishy breath and sweat (Choline)

Mr Hyde NITRO X Review Conclusion
Considering this is supposed to be their ‘upgrade’ on Pro Supps’ popular pre-workout supplements (Mr Hyde and Mr Jekyll), it doesn’t seem much like an upgrade.
Basically, you can see from the list of potential side effects why we can’t recommend Mr Hydr NITRO X. It’s potentially quite harmful, and you don’t want to waste your money on a supplement that can ruin your gym sessions – especially when you’re paying to benefit from improved workouts…
