Dr Jekyll Pre Workout Review

What Is Mr Hyde Pre Workout - picture of dr jekyll and mr hyde

Those of us that workout hard, struggle to find an energy supplement that performs as it says it does. At the same time, most of us don’t really want that feeling like we’re crawling out of our skin.

If you have ever taken too much of any stimulant, you can related to the jitters and sleepless nights. That why I wanted to bring it down a notch and review a product for those that may be a little less tolerant of caffeine.

The well researched and thought out ingredients make Dr. Jekyll the most powerful stim-free pre workout I’ve found thus far. Keep in mind that no stimulant-free pre workout can give you quite the energy that caffeine brings. However, this one is the next best thing.

What Makes this Non Stimulant Pre Workout Perform

Dr. Jekylls combination of nootropics, amino acids, and thermogenics come together to make a strong and well-rounded pre workout. The ingredient, creatine is a highly studied compound, proven to create sustained endurance and build muscle.

The 1.6 grams of Beta-Alanine gives sustained endurance and makes a difference when it comes to training harder and for exercise performance.

NooLVL is a signature compound that works like nitric oxide, bringing more blood flow and more oxygen to the muscles for a stronger pump, as well as push your brain into maximum focus.

Dr. Jekyll’s thermogenic ingredients are jitter-free. They increase metabolism and heat up the body, bringing you more energy and burn fat more efficiently.

This stimulant-free formula maximizes performance and helps to improve muscle recovery. Dr. Jekyll’s ingredients are safe to use, though there is small amounts of artificial flavor and color added.

If you are on the fence about trying Dr. Jekyll pre workout, Pro Supps offers a 100% satisfaction guarantee.

How to Take Dr. Jekyll Pre Workout

The directions are to mix 1 scoop with 8 oz of cold water. This should be done approximately 15 to 30 minutes before exercise.

If you tend to be sensitive to pre workout supplements, it’s advised to start out with less than a full serving for the first time.

Dr. Jekyll Pre Workout Review -  Jekyll pre workout ingredients

Dr Jekyll Ingredients

Dr. Jekyll contains some of the same effective key ingredients as other pre workout supplements. Things such as beta-alanine and creatine can be critical.

Additional ingredients are added that are meant to bring more blood flow, focus, motivation, and energy to make up for the lack of caffeinated stimulants.
These non stimulant pre workout ingredients are still very similar to the other popular Pro Supps pre workout supplements. The main difference of course is the Dr. Jekyll Pre Workout caffeine content.


This is an amino acid that is also made in the body. Beta-alanine enhances performance by decreasing muscle fatigue and increasing the amount of physical exertion. It can also be used to enhance immunity while also working as an anti-oxidant.

Creatine HCL

HCL is the most effective type of creatine and is proven to boost strength, enhance exercise performance, and increase muscle mass.


This amino acid is added to help produce epinephrine and dopamine which strengthen mood and increase motivation levels.


Optimizes and enhances blood flow for improved muscle pumps, endurance, focus, and nutrient delivery.


Similar to ashwagandha, this ingredient improves training response and works to promote healthy stress management support.

Celastrus Paniculatus

Another nootropic that works as an anti-oxidant to support healthy cognition and sustained focus.

This ingredient is ground in a special mushroom, and helps to improve cognition and focus.

Other Ingredients

There are natural and artificial ingredients for taste and color. Dr. Jekyll also uses Sucralose, an artificial sweetener made from sugar.

Dr Jekyll Nitro X Pre Workout

Pro Supps makes a middle of the road pre workout with just 100 mg of caffeine which may be just right for many of you. Dr Jeyll Nitro X shouldn’t give you the caffeine jitters and still comes with all the power, strength, and endurance ingredients.

The main difference with Dr. Jekyll NitroX is that it’s made for people who want a smaller amount of stimulant but still get muscle pumps and performance with less energy from stimulants.

Dr. Jekyll NitroX Benefits

  • Increased pumps and vascularity
  • Raises focus and motivation
  • Huge muscle gains and endurance
  • Very low stimulants 
  • Enhanced energy and enthusiasm

Dr. Jekyll Nitro X Ingredients

Nitro X is considered a low stimulant pre workout that contains only 100 grams of caffeine. 100 grams is a minimal amount that is equal to a cup of coffee and works well for those that are slightly caffeine intolerant.

It is still recommended to start out slow with a smaller serving since it is a powerful pre workout and contains other stimulants such as Teacrine that contains natural caffeine.

Even though it has a reduced caffeine quantity, it still provides high amounts of other pre workout ingredients that you would expect in order to get strong muscle pumps and increased endurance.

Dr. Jekyll Nitro X contains a strength-endurance matrix, a pump matrix, and an energy and focus matrix. These blends include beta-alanine, creatine HCL, L-Citrulline, and L-Arginine (key amino acids).

Mr. Hyde Pre Workout – The Crazy One

What is pre workout for - Mr Hyde

Here is Dr. Jekylls crazy brother that packs more punch than most other high stimulant pre workouts. This supplement is on the other far end of the scale when it comes to caffeine energy.

The main difference between Mr. Hyde and Dr. Jekyll is not the focus and pump, but its stimulating blend of high caffeine.
Mr Hyde is packed with all of the essential ingredients that should be in a pre workout and is very reasonably priced as well. I had great luck with this one during my Mr. Hyde pre workout review.

  • 420 mg of caffeine is considered a high stim pre workout
  • Thermogenic ingredients for fat burn and promoting weight loss
  • Neotropic ingredients for cognitive function, focus, and motivation
  • 500mg of Nitrosigine to increase blood flow for vascularity and muscle pump
  • Extra amino acid proteins for prolonged endurance and increase muscle performance
  • 0 Sugars, 0 Carbs, 0 Calories
  • Price is less than $1.00 per serving

Dr. Jekyll Pre Workout Verdict

What are the benefits for a preworkout - mr hyde nitro x - drink shaker

Pro Supps offers a pre workout for just about everybody. If you are caffeine intolerant, Dr. Jekyll Stimulant Free contains plenty of alternative ingredients to get maximum muscle pumps, focus, and motivation. I highly recommend Dr. Jekyll non-stim pre workout if caffeine is not your friend.

If you are middle of the road, give Dr Jekyll Nitro X low stimulant a try with its 100mg of caffeine and powerful amino acids. And lastly, if you choose Mr. Hyde high stim, beware, proceed with caution.
Whichever one of these three pre workout options you pick, all of them contain safe ingredients, are quite inexpensive, and come with excellent customer reviews.
