There are also other product lines under the Hyde brand. The Hyde is a high-stim product with Yohimbe, the Hyde Nightmare contains moderate to high stimulants, and the Hyde Max Pump is a zero-stimulant product for more pump and endurance. Many of these products can be stacked and cycled, although total caffeine consumption must be monitored.

What Is the Mr. Hyde Pre-Workout Powder Supplement?

Mr. Hyde Signature pre-workout is marketed as a banned substance-free product that boosts physical energy and mental focus. The desired results are more pumps and, thus, better exercise performance. The transparent ingredients list features four major categories – niacin, strength matrix, intensity matrix, and stimulatory matrix – that, according to the manufacturer, allow for dosage flexibility. 

The powder pre-workout supplement is gluten-free, but it must also be emphasized that it’s manufactured in a facility where potential allergens are processed. These potential allergens include eggs, milk, soy, wheat, tree nuts, fish, and shellfish, meaning individuals allergic to these food items must take precautions. However, there doesn’t seem to be a report of allergic reactions when Mr. Hyde pre-workout is recommended. 

A single-level scoop of Mr. Hyde pre-workout mixed well with a 10-ounce glass of water (i.e., one serving) is sufficient for daily use. But if you must take more than one serving, limit yourself to two within 24 hours. You should also build up your tolerance before drinking two daily servings. 

If you purchase from the official Prosupps.com website, you will get a 30-day full money-back guarantee. 

What Makes Mr. Hyde Pre-Workout Powder a Good Pre-Workout Supplement?

There are three ingredients that we look for in pre-workouts before we consider them safe and effective, namely, L-citrulline (6-10 grams), beta-alanine (2-5 grams), and caffeine (250-350 milligrams) in every serving. The trifecta of ingredients works in synergy to boost physical energy, mental focus and alertness, and mood, which are vital in achieving maximum exercise performance. The absence of one of these ingredients or the presence of less than the minimum recommended amount in any of these ingredients will compromise the efficacy of a pre-workout. 

Every container of the Mr. Hyde pre-workout contains 30 servings; each serving size (i.e., one scoop) has 7.2 grams. The main ingredients, their amounts, and their exercise-related benefits are summarized below. 

Niacin, also known as Vitamin B3, aids in converting nutrients into energy, muscle recovery, and fat metabolism. It also aids in preventing the release of free fatty acids that otherwise can result in the premature use of glycogen in the muscles. 

There are four ingredients in the strength matrix. First, beta-alanine (2 grams) is vital in producing carnosine, a compound that decreases the buildup of lactic acid in the muscles during intense exercise. This means delayed muscle fatigue and, thus, improved exercise performance. Mr. Hyde pre-workout meets the beta-alanine minimum recommended amount. 

Second, L-Citrulline L-Aspartic Acid 1:1 (500mg) is a combination of amino acids with different but complementary functions in exercise performance. L-citrulline converts into L-arginine and nitric oxide in the body, enabling the blood vessels to dilate and allowing more nutrients and oxygen to flow. L-aspartic acid can delay muscle fatigue and improve muscle strength. 

But while L-citrulline is present in Mr. Hyde pre-workout, it’s too low to make a significant difference in work capacity! At just 500 mg, it’s well below the 6-gram minimum recommended amount. This is a minus point in our books. 

Third, as part of a supplementation program, creatine monohydrate (1 gram) can also improve exercise performance. This is through faster muscle recovery and better tolerance for heavy training loads. This may well offset the deficit in L-citrulline but not significantly. 

Fourth, Nitrosigine (500 milligrams) is a patented version of inositol-stabilized arginine silicate useful in increasing nitric oxide in the bloodstream. Among its benefits is increased blood flow, which results in more oxygen and nutrients being fed into the muscles. 

The ingredients in the Intensity Matrix and their possible effects are: 

The Intensity Matrix is formulated to increase mental focus, concentration, and cognitive function. Fitness enthusiasts and professional athletes are known for these traits because intense workouts are as much about physical capacity as mental ability. 

The Stimulatory Matrix contains the stimulants in Mr. Hyde pre-workout, three of which are present. First, caffeine anhydrous (169 milligrams) is derived from the leaves and seeds of the coffee plant. This is a highly concentrated caffeine powder that, once consumed, enters the brain via the bloodstream and enhances the actions of naturally-occurring stimulants. These include dopamine, adrenaline, and norepinephrine. 

The result: You feel more energized, alert, and focused! This is true when you drink a single serving of Mr. Hype pre-workout, with the stimulatory effects kicking in about 30-45 minutes afterward. 

Second, di-caffeine malate (37 milligrams) is a combination of caffeine (75%) and malic acid (25%). This buffered caffeine version brings on the stimulant effect but with little risk of a sudden caffeine-induced crash. 

While caffeine anhydrous and di-caffeine malate amount to 206 milligrams of caffeine-related ingredients, these still don’t meet the minimum recommended amount (250 milligrams). This means that Mr. Hyde Signature is a fairly low-stim pre-workout, meaning you can still enjoy the stimulatory effects of caffeine without getting the jitters. 

Third, theacrine (16 milligrams) has chemical properties similar to caffeine, which is found in tea and coffee. It also has stimulatory effects, including boosting cognitive functions and delaying fatigue. 

That said, we think the Mr. Hyde Signature pre-workout is a solid product that delivers reliable results. Most users agree with statements that attest to its effectiveness in boosting physical energy, mental concentration and cognitive function, and mood before and during training sessions. With consistent use, these physical and mental benefits become more pronounced, too, especially when combined with healthy lifestyle habits, a proper nutrition plan, and a personalized exercise program. 

But we can’t say it’s an excellent pre-workout for good reasons. For one thing, the amounts of L-citrulline and caffeine in Mr. Hyde pre-workout don’t meet the minimum recommended amounts for best results. Unlike its namesake, there’s nothing “monstrous” about the results.

For another thing, the low-stim nature of Mr. Hyde pre-workout means that it will likely not work as desired among professional athletes who prefer high-stim pre-workouts. But Mr. Hyde Signature pre-workout can be stacked with other dietary supplements, although caution is advised when stacking with supplements containing caffeine.  

Who Is Mr. Hyde Pre-Workout Powder Supplement Pre-Workout For?

Mr. Hyde Signature is intended for healthy adults 18 years old and above, specifically for beginners, fitness enthusiasts, and performance athletes who want a low-stim pre-workout. Minors shouldn’t consume pre-workouts because of the high risk of side effects caused by the stimulants, particularly caffeine, such as irritability, palpitations, and sleep difficulties. 

Other high-risk cohorts include pregnant and lactating women, individuals with underlying medical conditions and taking prescription medications for their health issues, and persons who will undergo surgery or have recently undergone surgery. 

What Are the Best Flavors of Mr. Hyde Pre-Workout Powder Supplement?

There are three flavors available – Blue Razz Popsicle, Watermelon, and Lollipop Punch. While these are all yummy flavors, the Watermelon flavor is the best because of its true-to-taste, refreshing flavor profile. The Lollipop Punch and Blue Razz Popsicle may be slightly sweeter than expected for some individuals. 

Conclusion

Mr. Hyde Signature pre-workout has the three ingredients we look for in the best pre-workout supplements; thus, it has great promise. But it falls significantly short in two ingredients – caffeine and L-citrulline – in terms of the minimum recommended amount, compromising the product’s overall efficacy. 

Generally speaking, Mr. Hyde pre-workout works well for most users because it delivers on the promise of increased energy, concentration, and mood. But it may not be as effective for high-performance athletes with greater expectations from their dietary supplements, particularly pre-workouts with direct effects on their exercise performance. In this case, it may be better to consider other high-stim pre-workouts with the appropriate amounts of beta-alanine, L-citrulline, and caffeine.
