About The Product

Dr Jekyll NITRO X is a pre-workout supplement made by Pro Supps. It costs $59.99 for 30 servings and comes in 2 flavor options – Lollipop Munch and What-O-Melon.

It sounds, tasty and it’s advertised to deliver all the right benefits for a pre-workout supplement. So it’ll be interesting to see whether the ingredients inside Dr Jekyll NITRO X can back up these claims.

But before that, we’ll tell you a bit about the company behind the product (for those that don’t know).

Who are Pro Supps? 

Pro Supps are a supplements company that’s gained respect over since it was formed. As a result, they’ve attracted some big names such as Shawn Rhoden and Jason Poston to the list of athletes they sponsor –  not bad.

So what are they known for? Well, Pro Supps has gained a lot of attention for their pre-workout supplements – especially the first Mr Hyde & Dr Jekyll products.

For this reason, they decided to release 2 new supplements in 2017; Mr Hyde NITRO X and this one (Dr Jekyll NITRO X). We got hold of the Water-O-Melon product to review here – so let’s get to the main course below.

Dr Jekyll NITRO X Ingredients Explained

Dr Jekyll NITRO X contains 9 ingredients overall. Our first impressions of this pre-workout is good; it doesn’t contain any harmful ingredients that’ve been banned, and no proprietary blends either (meaning the exact dosage of each ingredient has been listed).

But from first glance, we noticed that many key pre-workout ingredients that have proven to enhance your workout are missing. We’ll explain more about this when we take you through each ingredient in Dr Jekyll NITRO X.

It’s definitely worth knowing about each ingredient; so we’ll analyze the nutrients inside this pre-workout – so you can see how effective Dr Jekyll NITRO X really is.


Here’s Everything You Need To Know:


This compound always splits opinions; Beta-Alanine has shown to boost muscular endurance, but also causes a side effect called paresthesia.

What’s paresthesia? Well, it’s a tingling and itching sensation on the skin of your face and body…Personally, we don’t enjoy this side effect as it distracts us from making gains.

For this reason, we try to avoid supplements containing this ingredient. We believe that if you’re paying for a gym supplement, then you shouldn’t experience any unwanted side effects.

Creatine Nitrate 

This is a form of creatine that’s believed to improve your strength endurance, as well as muscle pumps. However, there hasn’t been any study that proves this ingredient works – meaning Creatine Nitrate is an unreliable ingredient.

As a result, we consider Creatine Nitrate as an unreliable ingredient. We would’ve preferred to have Creatine Monohydrate here instead (as this has proven to be safe and effective).

Simply put, Creatine Monohydrate has been used by athletes and bodybuilders since the 1980’s – so there’s no need for companies to try and replace it.

As the age old saying goes: ‘don’t try to fix something that’s not broken’.


Choline is always one of the worst ingredients you can find in pre-workout supplements. Simply put, it hasn’t shown to offer any benefits to improve your gym session, but causes your breath and sweat to smell fishy.

Personally, we don’t want to smell like fish in the gym…For this reason, Choline is basically a useless ingredient that causes a side effect.


Caffeine Anhydrous

If you don’t know what anhydrous means, it basically means Caffeine has been dehydrated into powder form (so it can be added to supplements).

Caffeine is the best and safest stimulant you can find in pre-workouts; it’s consumed in products such as tea & coffee everyday and is proven to enhance your strength, endurance, focus and energy levels in the gym (helping you perform better).

For this reason, we consider Caffeine to be a key ingredient in pre-workout supplements. It’s also been dosed sensibly in Dr Jekyll NITRO X – at 100mg per serving.



Theacrine is another stimulant that’s believed to provide similar benefits to Caffeine. However, it’s not been studied much – making it an unreliable ingredient.

However, as there’s only an overall 125mg dosage of stimulants in Dr Jekyll; you’ll still avoid jitters and energy crashes here. But as a general rule, we recommend avoiding pre-workouts containing more than 1 stiumulant (as this usually leads to over-dosages of Caffeine, which can cause jitters and crashes).

Personally, we only recommend pre-workouts containing under 200mg Caffeine (or stimulants); this ensures that you experience the full benefits such as improved strength, endurance, focus and energy levels, without suffering from side effects.


Glycerol is believed to improve your strength and energy levels – but no studies have proven whether it works (making it an unreliable ingredient).

Ultimately, we would’ve preferred to have Citrulline Malate here instead (as it’s prove to deliver intense muscle pumps). This is why it’s important for companies to do their research when formulating their products – and why you need to make sure the ingredients inside the product you buy are proven to be effective.

L-Citrulline Aspartate 

This is a mixture containing L-Citrulline. However, we’re not sure why Pro Supps didn’t simply add Citrulline Malate instead – as it’s tried-and-tested (unlike Citrulline Aspartate). We’l explain more about this below.


Arginine Silicate 

If you’re not sure what this is, it’s simply a mixture of Arginine and Silicate. But it’s important to know that any ingredient containing Arginine is ineffective.

Why? Answer: Because Arginine has a poor absorption rate, meaning it’s ineffective when orally supplemented. For this reason, we don’t like seeing Arginine or ingredients containing it, in pre-workouts.

In fact, this is exactly why Citrulline Malate is better; Citrulline converts into Arginine in your kidneys (taking away the issue with Arginine’s poor absorption rate).


L-Norvaline is a branched chain amino acid that’s believed to improve nitric oxide production; this would enhance your muscle pumps…if it worked.

Basically, there hasn’t been any studies proving that L-Norvaline actually works – making it an unreliable ingredient.

Side Effects

There are 2 ingredients in Dr Jekyll NITRO X that can cause side effects; Beta-Alanine & Choline.

As we’ve mentioned, Beta-Alanine can cause paresthesia, so we try to avoid pre-workout supplements containing this ingredient.

What’s paresthesia? Answer: Tingling and itching sensation on the skin of your face and body. Personally, we find it distracting when lifting weights in the gym…

Not only that, Choline is known for causing your breath and sweat to smell fishy – a good enough reason to avoid Choline, especially as it doesn’t offer any benefits.

Here’s the potential side effects from taking Dr Jekyll NITRO X: 

  • Paresthesia (Beta-Alanine)
  • Fishy breath and sweat (Choline)

Dr Jekyll NITRO X Review Conclusion

Considering Dr Jekyll NITRO X was made to be an upgrade from their previous pre-workout, it doesn’t look like it.

This pre-workout released in 2017 should be keeping up with the best products on the market. But it’s missing key pre-workout ingredients, so it’s being left behind by those that’re formulated better already – not a good thing for Pro Supps.

Not only that, it’s been reported to cause 2 side effects. We believe you shouldn’t suffer from any side effects if you’re paying to improve your workouts and physique.

For this reason, we can’t recommend Dr Jekyll NITRO X. Instead, take a look at the best pre-workouts on the market this year.
