About Mr Hyde Pre-Workout

Mr Hyde Pre Workout is sold by ProSupps. They describe the supplement as a pre workout with twice the energy of the leading brand, although we’re not sure what that leading brand is. Here’s what we noticed:

  • No prop blends. That’s always a good sign to start things off.
  • That’s a lot of caffeine. If we calculate correctly, it’s almost 400 mg per serving.
  • Two sizes: Can be bought at 15 or 30 servings, but of course we’ll always buy the max amount, right?

Mr Hyde Pre-Workout: Ingredient List

Strength Matrix

  • Beta-alanine. Beta alanine delays fatigue and allows you to lift more times than the other lifter next to you at the gym. It also serves as a really nice recovery ingredient for better gains.
  • Creatine. Creatine is critical when it comes to strength and muscle recovery. The form used is Creatine HCl, which is supposed to help cope with the bloated issues brought about by taking creatine. However, Creatine HCl is not easily absorbed compared to creatine monohydrate.
  • Arginine Silicate. Arginine Silicate is a fast-acting ingredient promotes performance through sustainable nitric oxide production.
  • Citrulline. Citrulline activates the necessary mechanisms and enzymes in the body that produces nitric oxide. We like it, but we’re questioning the way it was added below arginine silicate. Citrulline should also have at least a similar dose to beta alanine if we want it to work its best.

Caffeine Matrix

  • Caffeine. Mr Hyde shotguns 300 mg of caffeine to our faces. This is crazy considering 300 mg is around three cups of coffee’s worth of caffeine.
  • Di-Caffeine Malate. Combining caffeine and malic acid makes the whole compound more bioavailable. However, we do question the necessity of this ingredient in an already super-stimulating formula.
  • Caffeine + Citric acid blend. Another fast-acting form of caffeine.

Intensity Matrix

  • Choline bitartrate. Choline is a key brain chemical responsible for what makes our brain do what it does. As bitartrate, it’s the cheapest form and therefore the least absorbed. The 500 mg dosage won’t cut it.
  • Theanine. This nootropic is supposed to provide a sort of buffer against the stimulant spike caffeine provides. However, 50 mg can only dent it. You also need at least 200 mg to have any real calming effect when it comes to theanine.
  • N-Acetyl-Tyrosine. This is the best form of Tyrosine, an ingredient taken for focus and mood. However, the 50 mg dosage is too small.
  • Theacrine. Another caffeine source to an already redundantly stim-spiked formula. This is actually a premium ingredient that actually removes the side effects of caffeine while sustaining energy levels. Again, the 25 mg dose is too small to be of any significant use.
  • GABA. GABA is a feel good ingredient. However, supplements don’t really add it because it requires GRAMS to work. Even though Mr Hyde included Niacin - an ingredient that boosts GABA bioavailability - 25 mg might as well be 0 mg.
  • Yohimbe. This extract is a potent fat burner even in tiny doses. However, it has side effects related to palpitations and blood pressure. Still, the 3 mg dose should minimize the risk.

Thinking about ordering Mr. Hyde? We've put in the research so that you don't have to!

Who is Mr Hyde Pre-Workout made for?

Mr Hyde is definitely not for newbies or users who can’t stand caffeine. It caters to users who want to literally feel the energy in their veins with all the caffeine it has per serving.

What are Mr Hyde Pre-Workout’s benefits?

We’re not entirely confident about Mr Hyde’s benefits for pump and strength. You’ll definitely have some, but we think they’ll be smothered by the intense feeling of being super caffeinated.

Mr Hyde Pre-Workout: Side Effects

The amount of caffeine Mr Hyde has per serving is actually concerning. If you’re not used to being super stimulated, you could end up with a bad case of the jitters, nausea, and the crash. We’re also not sure if your gut can take this much caffeine if you take Mr Hyde without food.

Mr Hyde Pre-Workout: pros and cons


  • Super stimulation. Energy is the last thing you will not have.
  • Transparent labeling. No prop blends.
  • Good price. Not so bad when you compare it to its competitors.


  • Stim-driven. Relies too much on caffeine.
  • Overstimulation. Caffeine-naive users will definitely have a bad time.

Pricing info

  • 1 Can (15 servings): $24.81
  • 1 Can (30 servings): $29.99
  • Available online and in retail stores

Mr Hyde Pre-Workout: Summary

Mr Hyde pre workout is one of those supplements that you easily grow out of. It’s not particularly special when it comes to formulation and the harder you train, the more you realize caffeine alone just won’t cut it. However, that’s not to say Mr Hyde is just a glorified caffeine powder. It does boost some key aspects of performance, though not without the help of stimulation.

We think Mr Hyde will attract the type of user that wants something extreme, someone who wants to feel the supplement working. Caffeine in high amounts can do that. 

Should you take Mr Hyde? If you can take the energy or have a bottle of theanine with you to counteract the effects, then by all means buy it. Just make sure to not go over the serving suggestion.
