  • Contains some proven ingredients
  • No proprietary blend


  • Missing most key ingredients
  • Some ingredients under-dosed
  • Doesn’t contain stimulants

This Dr. Jekyll Pre Workout review will explain whether it can turn you from a mild-mannered guy into a voracious gym beast.
I know you’ll agree with me when I say—when we hit the weights, we want to have the explosive power and energy of an absolute freakin’ animal.
To obtain optimum returns, and feel like we are pushing our bodies to the max, we need
to be pushing through each and every set and rep as if it was the first.
And the best pre-workouts can achieve this.

Guys taking these phenomenal supplements have felt their training performance become almost superhuman—providing faster and larger muscle gains that their “normal” workouts simply can’t provide.

But does Dr. Jekyll deliver these results?
In this Dr. Jekyll Pre Workout review, I’ll explain everything—what it is, who it’s designed for, how it functions, and whether it actually works.
(Note: This pre-workout formula has changed  and we have updated this review as the formula is now in 2020.)
If you want to discover whether this pre-workout can turn you in a raging monster, or just leave you out of pocket—read on!

Dr. Jekyll Pre Workout Review

This Dr. Jekyll Pre Workout review wouldn’t be complete without first taking a quick overview of the product.
Marketed by respected supplement manufacturers, ProSupps, Dr. Jekyll forms part of a number of pre-workouts made by this company.

There have been a lot of changes from the supplement lineup of Prosupps which includes different versions of both the Mr.Hyde and Dr. Jekyll products. They have made a complete new look for all their supplements and formulated it in a way that Dr. Jekyll is now a stim-free pre-workout while Mr.Hyde is the stim version. There have been a lot of changes in the ingredient lineup for both of these supplement but unfortunately they are still today lacking in many areas despite all the changes.

So, to be clear—this Dr. Jekyll Pre Workout review is for the new formula(we updated this review), it’s not a Dr. Jekyll nitrox review.
Listen up.
Dr. Jekyll is a powdered pre-workout that is mixed with water to form a pre-training drink. It’s formulated to enhance training performance—therefore providing you with a more impressive physique.
ProSupps claim that this pre-workout will:

  • Create an intense focus.
  • Elevate physical performance.
  • Encourage muscles to grow.
  • Provide vein-popping muscle pumps.

Sound good?
Let’s see in the next part of this Dr. Jekyll Pre Workout review if it’s for you.

Who Should Use Dr. Jekyll Pre Workout?

Who Should Use Dr. Jekyll Pre Workout

  • Need their energy to reach whole new levels.
  • Require more stamina and endurance to push each set as hard and long as possible.

Who Should Not Use Dr. Jekyll Pre Workout?

Let me be honest with you in this Dr. Jekyll Pre Workout review.
It’s not for everyone.
Guys who should avoid this supplement, and pre-workouts in general, are those who:

  • Seek a “short-cut”—pre-workouts enhance your training sessions, but you still need to put in some serious gym-time, this isn’t a magic pill.
  • New kids on the block—supplementation isn’t how you start building impressive muscle—first develop a training program, learn how to use the weights correctly, and only then consider performance enhancers.
  • Aren’t looking for increased energy or improved training results.
  • Are eating unhealthily and not looking after the essential macronutrients.

How Does Dr. Jekyll Pre Workout Work?

Just before we examine in detail the ingredients in this Dr. Jekyll Pre Workout review—let me quickly mention the effects it’s designed to have on the body.
This supplement aims to:

  • Reduce fatigue by including chemicals that can prevent muscle acidosis.
  • Build muscle by utilizing the power of amino acids.
  • Increase stamina through the inclusion of muscle-powering fuel.
  • Elevate concentration with cognitive enhancers.

Dr. Jekyll Pre Workout Ingredients

dr jekyll pre-workout ingredients
Now down to the gritty detail in this Dr. Jekyll Pre Workout review—what’s under the hood?
With 10 ingredients in Dr. Jekyll, this is a compound-heavy formula. Let me take you through the main players.

  • Beta-alanine—a powerful pre-workout ingredient which can increase endurance by preventing the build-up of muscle-killing lactic acid.1
  • Arginine Silicate – Nitrix oxide booster for muscle pumps.
  • Calcium —thought to reduce the onset of DOMS (delayed-onset muscle soreness) and boost muscle growth—however, studies have indicated there’s little evidence that it works, and any improvement requires a dose five times higher than in Dr. Jekyll.3
  • Creatine—boosts ATP (adenosine triphosphate) production which is the fuel enabling muscles to contract.4
  • L-Tyrosine for mental function and focus
  • Lions Mane for focus
  • Alpinia galanga helps with mental alertness and focus
  • Ashwagandha has shown to be effective in increasing strength and muscle mass
  • Aframomum Melegueta helps increase the metabolism
  • Black pepper extract to increase the absorption of ingredients

Dr. Jekyll Pre Workout Ingredients Breakdown

Dr. Jekyll does contain some proven performance enhancers, but is it up there with the big boys in the pre-workout market?
Here are the ingredients that the most powerful pre-workouts contain—and a checklist of how Dr. Jekyll performs.

  • ✘Caffeine
  • ✓Beta-Alanine
  • ✘Citrulline Malate
  • ✘Betaine Anhydrous
  • ✘L-Theanine
  • ✘Acetyl-L-Carnitine
  • ✘Black pepper extract (Bioperine)

Containing only one of the most powerful proven performance-enhancing ingredients—Dr. Jekyll appears somewhat poor.
It has the inclusion of arginine silicate instead of the Citrulline malate but we still would like to see a proper dose of either citrulline malate or citrulline to get more of the nitric oxide effects.
It has some new and exciting ingredients that may not all be bad but the doses of them are quite low.
The beta-alanine is underdosed as well so overall Dr.Jekyll is a weak formula and top of that it’s missing all stimulants.

Dr. Jekyll Pre Workout Side Effects

Dr. Jekyll Pre Workout Side Effects
Adverse health effects from pre-workouts are rare. Although one of the ingredients,  beta-alanine, can sometimes produce side effects, including:

  • (paresthesia) Itching (from beta-alanine).8

Since it doesn’t contain any caffeine we eliminate many side effects that come along with the use of pre-workouts.

Dr. Jekyll Pre Workout Before After Results

The evidence so far in this Dr. Jekyll Pre Workout review hasn’t suggested that it’s a pre-workout to be ranked among the best.
But what about the guys at the gym? What effects have they seen from using this supplement?
Here are the results they’re witnessing:

“Felt a little buzz.”


“Tastes nice but doesn’t do anything for me.”


Doesn’t do anything, even increased dosage but nothing.”

K Bar

Dr. Jekyll Pre Workout Review Conclusion
Dr. Jekyll is a pre-workout that does contain some proven performance enhancers—the issue is, there are not enough of them nor are they in sufficient doses.
It’s not the best pre-workout.
Despite containing 10 ingredients, it’s lacking in the excellent citrulline, betaine, and carnitine. Instead, the manufacturers have decided to go with the less powerful nitric oxide booster arginine silicate and the unproven calcium.
The bottom line.
As the customer testimonials indicate in this Dr. Jekyll Pre Workout review—this supplement isn’t going to turn you into a raging monster.
My advice.

Skip this weak pre-workout. Choose one of the best pre-workouts on the market—that is, one which includes the serious performance-enhancing players I mentioned earlier. Only then will you become the beast you deserve to be.

“Does Dr. Jekyll Really Work?”

Additionally, the problem was exacerbated since the Mr. Hyde pre workout label didn’t disclose the picamilon ingredient.
