We’re going to take a very close look at the ingredients and see if all these claims are possible.

Full Ingredient List Analysis

Mr Hyde by Pro Supps Pre-Workout Supplement Ingredients List

Once again, the first thing that stands out is the Caffeine content. 419mg is nothing to scoff at, and some people who are sensitive to it may even experience SEVERE side effects. Let’s take a look at it first and then go over the main ingredients:

Caffeine Anhydrous – This is just a dehydrated form of caffeine. Certain research shows that it may be more potent than regular Caffeine.

Dicaffeine Malate – It’s an ionically bonded compound of Malate (malic acid) and Caffeine that is much easier on the stomach than regular form of Caffeine. Some inconclusive research suggests that malic acid may be able to prevent the energy crash that usually comes after caffeine.

Caffeine Citrate – It functions in the exact same capacity as regular Caffeine, except for the fact that it’s absorbed significantly faster.

The problem with this form is that it is substantially more acidic than normal and has a higher potential for some unwanted side effects.

Now let’s take a look at the main ingredients:

Beta-Alanine – It’s the main focus of this supplement and a pretty solid choice. No pre-workout is complete without it because it substantially increases physical performance, anaerobic and aerobic exercise capacity as well as reduces the onset of neuromuscular fatigue.

That said, the gold standard dose for most athletes and bodybuilders sits at 3.2-6.4 grams per day, which means that, unfortunately, this product has it slightly under-dosed.

Creatine Nitrate (NO3-T) – It’s simply put a combination of both Creatine and Nitrate in one. Usually, it comes at around 67.5% Creatine content, and the remaining 32.5% are nitrate.

This form has a very particular upside, in that it increases vasodilation and muscle pump, effectively removing the need for other pump products in a supplement.

However, this dosage presents a huge problem, since this supplement only contains 1 gram of this compound. This means that you’re only getting 675mg of creatine with each serving.

That is a severely under-dosed quantity because the gold standard for Creatine to be effective is AT LEAST 5 grams per day.

No wonder the manufacturer claims that Dr Hyde pre-workout only PROMOTES size & strength by including Creatine Nitrate because it most certainly can’t provide effective results with such a little dose.

However, we can’t effectively call Creatine in this supplement as a “Label-Dressing” ingredient, as it does provide a certain, if very small, benefit.

Agmatine Sulfate – Agmatine is essentially Arginine, but without the carboxylic acid. It increases nitric oxide synthesis significantly more than Arginine, aids in nutrient partitioning, regulates certain hormones, including insulin. It also provides a nootropic effect, improving cognitive function.

This substance is incredibly powerful and effective and provides a substantial pump effect. We can concur that this Mr Hyde Supplement would provide people with “skin-tearing pumps”, as the label promises, when combined with Creatine Nitrate.

L-Citrulline Aspartate – It’s a form of Citrulline that’s bound to L-Aspartate. Citrulline reduces fatigue, improves aerobic and anaerobic endurance and generally improves performance.

However, we have to say yet again that the gold standard dose for this substance is over 6-8 grams before exercise. The quantity contained in this product is abysmally under-dosed!

We’re certain that you’re beginning to see a pattern here: this supplement has some severely under-dosed ingredients, and can’t possibly provide most of what it claims.

Now that we’re done with the main ingredients, let’s take a look at the Intensity Matrix:

Choline Bitartrate – This substance is claimed to increase athletic performance, but so far there haven’t been any scientific studies that prove and establish these claims.

That said, it does improve cognitive brain function and mood, as well as increase alertness.

Hordenine – It’s supposedly used as a stimulant and fat burner, but so far it is severely under-researched, and there are no scientific studies or clinical trials that prove any of its purported benefits.

We think that this ingredient is completely unnecessary and shouldn’t be consumed by humans due to almost complete lack of valid research done on the substance.

Effectively nothing more than “hype and label dressing”.

N-Methyl L-Tyramine HCI – It’s a new stimulant, but absolutely no human research data exists on this compound. Other than that, it is suggested that this compound decreases blood sugar levels while increasing insulin secretion and also has a stimulating effect on certain neurotransmitters.

It is supposedly a replacement for the dangerous, controversial and ultimately banned compound used for sports supplements called 1,3-DMAA.

However, it is largely unstudied and may be rife with potential side effects and various health hazards – so we can’t safely recommend using it until more studies are done on it with confirmed and concrete findings.

Gamma-Aminobutyric Acid (GABA) – Several inconclusive studies suggest that this substance improves and increase the secretion of growth hormone. However, the few studies that were done on this compound were performed with a dosage of 5 grams and more.

It is included at only 25 mg in this product, which is an utterly insignificant dose and effectively only a “Label-Dressing”.

Have other Hyde Pre-workout reviews mentioned this?

At this point, even a product like B-NOX Androrush (Bullnox) by Betancourt, which is one huge proprietary blend and has certain problems of its own, still looks significantly better than Hyde Pre-workout.

Yohimbe Bark Extract – It’s Yohimbine and is used for fat loss. However, it has proven to be potentially dangerous and rife with side effects.

“Yohimbine – This drug may cause severe hypotension, hypertension, abdominal distress, and weakness.

That sentence should tell you everything that you need to know about this ingredient, taken directly from

Rauwolfia Vomitoria Root Extract – This medicinal herb is used to treat hypertension and mental disorders at significantly larger doses than included in this product. However, there are once again almost no scientific research studies done to support and establish these claims, making it yet another ingredient that has been included but severely under-researched and even under-dosed.

Yet another bad pattern when it comes to the Pro Supps Mr Hyde pre-workout supplement powder.

Seriously, are other mr hyde pre workout reviews even noticing this? How many times have we asked that now?

Given all of these ingredients, we can safely recommend another supplement instead, like Catalyst Pre-Workout by Strength which does the job much better, even though it too contains a couple of under-dosed ingredients.

Niacin – It plays a role in the energy release to the cells of your body, although its primary benefit is the reduction of blood cholesterol levels.

Mr Hyde Supplement Features – The PROs and CONs

So now that we’re taken a close look at all of the ingredients and seen what the product has to offer – let’s take a look at the advantages and disadvantages of using this pre-workout


  • Extreme Energy Kick
  • Absolutely massive pump effect
  • Affordable

The energy kick due to the absurd caffeine dose is absolutely massive.

The pump effect is incredible and definitely something that this supplement excels at. That’s pretty much the only real great thing about this supplement, unfortunately.

The price is pretty decent, too – another saving grace of Mr Hyde pre-workout supplement.


  • Substantial Jitters
  • Bad Taste
  • High Chance of Possible Side Effects!
  • Not For Beginners!
  • Under-dosed ingredients!
  • Under-researched and “label-dressing” ingredients!

Many users have reported experiencing substantial jitters, feelings of anxiety and tenseness due to the ludicrously high caffeine dose.

The taste of this supplement is not what you’d call great – in fact, a lot of people reported that it tasted too bitter and “chemical”.

This product has a substantially high chance to cause some unwanted side effects, due to the fact that there are some ingredients included that are completely under-researched, as well as those included that are KNOWN to cause side effects.

Finally, the fact that most of the main ingredients are under-dosed is the biggest downside.

This probably explains the affordable price, but we’d rather pay something extra than get an underperforming supplement that just doesn’t do all that much.

Our Final Verdict and Evaluation of This Pre-Workout

We are completely disappointed with this supplement. The massive pump effect that it provides is the only saving grace, but that is not nearly enough to call this Mr Hyde by Pro Supps pre-workout powder good.

It’s not even enough to call it decent. The only thing we can call it is sub-optimal.

There are just too many downsides, and thus we can’t in good conscience recommend it to our readers.

Beginners should definitely steer clear of this supplement because they are going to be extremely overwhelmed by the humongous caffeine dose.

Those inexperienced with pre-workout or sports nutrition supplements should also stay away because this compound contains too many ingredients that are potentially dangerous and even ineffective.

Serious or professional bodybuilders and athletes should also look towards something else, as the under-dosed ingredients just won’t be all that effective for them and will leave them extremely disappointed.

Honestly, we can only recommend it to caffeine-junkies or those specifically looking for an insane pump effect combined with a crazy caffeine kick.

So if you’re like us and don’t like this supplement, we can recommend you a much better one. Transparent Labs PreSeries BULK offers you a truly reliable, effective and efficient pre-workout supplement that includes full, clinically tested doses that actually matter and provide real results.

The ingredient list it sports is completely transparent, and it contains everything you need to have an efficient training session.


We think that this Mr Hyde Supplement is not really worth your time or money.

We only recommend taking Mr Hyde pre-workout powder for people who are not sensitive at all to any of the ingredients and want an extremely high dose of caffeine as well as a massive pump effect – but don’t want to overload themselves with too much of other ingredients like Creatine and beta-alanine.

We sincerely hope that Pro Supps steps up its game regarding this supplement and improves it in some way, preferably by removing the dangerous an under-researched ingredients and adding bigger doses to those elements that actually work.
