What is Mr Hyde pre-workout?
According to the official ProSupps website, there isn’t a lot their Mr Hyde pre-workout can’t do. Specially formulated “to deliver intense, sustained energy and focus and increased power, strength and endurance, while delivering extreme pumps.”
Now, this is a hell of a sales pitch and a pretty impressive list of benefits, even for a pre-workout supplement. But what does all of that actually mean and which ingredients (and in what quantities) does Mr Hyde pre-workout contain in order to deliver all of those supposed benefits?
Let’s take a closer look at the ‘Supplement facts’ label and find out for ourselves…
Mr Hyde pre-workout ingredients made simple
One of THE most important things to look out for when researching the perfect pre-workout supplement for you, and something that our Mr Hyde pre-workout review should consider before anything else, is whether this product uses proprietary blends!
The answer…? No! Whilst it is made up of a number of ingredient blends, ProSupps do offer the exact quantities of each of the ingredients within them. That means you know how much of everything you are putting in your body, which is without doubt the most important factor when choosing any nutritional supplement!
Mr Hyde’s ‘strength matrix’ contains some of the biggest hitters in the supplement world with significant scientific research to support their positive physiological effects for training.
Beta alanine (2.5g), creatine HCL (1g), and l-citrulline (500 mg) have the potential to improve endurance and fight fatigue; boost strength and lean muscle mass gains; and generate a pretty sweet ‘pump’, respectively.
In order to do all of that, however, these ingredients must be dosed at optimum levels! And, it is exactly there, that Mr Hyde’s impressive looking strength matrix, falls flat on its face!
According to the most recent studies, the optimum dose of beta alanine is between 4-6g per day for an extended period of time. The 2.5 g per serving of Mr Hyde, therefore, is somewhat shy of this ideal dose. Having said that, there aren’t many pre-workout supplements on the market which get their beta alanine dose right so this isn’t too bad!
The 1.5g of Creatine HCL, on the other hand is quite frankly laughable. Requiring a daily dose of 5g after an initial week long loading phase of up to 20g, creatine requires significant supplementation in order to be effective.
Mr Hyde simply doesn’t offer these kinds of quantities. There isn’t a pre-workout available with an optimum dose of creatine included, full stop! There simply isn’t enough room in the scoop. If you want to take creatine and you want it to do what it is supposed to, then your best bet is to source a pure creatine supplement.
The ultimate ‘pump’ generating ingredient. Unfortunately for users of Mr Hyde, 500 mg just isn’t going to cut it! The science suggests that you need 3-6g per day in order for citrulline to be of benefit to your circulation.
What about the 500 mg dose of arginine I hear you ask…?! Waste of time. When supplemented orally, the vast majority of arginine is broken down by the liver and therefore never has the opportunity to do it’s business. Citrulline is actually turned into arginine by the body and is a far more effective way of boosting arginine levels in the blood!
Now this is where this Mr Hyde pre-workout review takes a turn for the better. Containing a whopping 420 mg, the ‘Caffeine Matrix’ packs a serious stimulant punch! The vast majority of this matrix (300 mg) is made up of caffeine anhydrous (which is probably the most common form of caffeine in pre-workout products).
The remaining 120 mg is a combination of Di caffeine malate, which helps to reduce the gastrointestinal stress associated with large servings of caffeine, and a caffeine citric acid blend.
This monumental dose of caffeine is certainly not for the faint hearted and we would only recommend taking the full serving if you have experience taking stimulant heavy products. If not, your best bet is to consume this product in much smaller quantities in order to test your tolerance levels.
This really doesn’t contain anything of note in any meaningful quantity so our Mr Hyde pre-workout review is gonna go ahead and move on pretty quickly!
Mr Hyde side effects
Any pre-workout supplement containing over 400 mg of caffeine is likely to have some minor side effects at the very least.
Scientific studies suggest that you can consume up to 400 mg of caffeine a day safely, with doses above that figure producing no more benefits but more likely adverse effects instead. Some of the side effects associated with this kind of caffeine consumption include diarrhea, vomiting, nausea, the jitters and even anxiety.
As a result, if you are going to consume this Mr Hyde pre-workout, we suggest starting with a half serving at the very most in order to test your caffeine tolerance levels. Once you have done so without any adverse effects, you can begin to slowly increase to a full dose!
The other ingredients which make up the Mr Hyde product are simply not dosed at high enough levels to pose any potential side effects!
Was Mr Hyde pre-workout banned?
Sort of! Back in 2016, ProSupps recalled a number of products in their Dr Jekyll and Mr Hyde ranges as a result of the inclusion of an unapproved dietary ingredient called Picamilon.
Both ranges seem to be up and running again, however, with no sign of the offending ingredient.
Pros and cons
At $29.99 on Amazon, Mr Hyde comes in at just shy of a buck per serving, which puts it pretty much in the middle of the road as far as value for money goes.
There are a staggering 10 different flavour options to choose from within the Mr Hyde pre-workout product range, including cotton candy, lollipop punch and sour green apple. That should be enough options to please even the fussiest of customers!
Our Mr Hyde pre-workout review can be summarised fairly simply in two words… STIMULANT HEAVY!
It is almost impossible to look beyond the mammoth 420 mg dose of caffeine within this ProSupps pre-workout. Guaranteed to get you absolutely buzzing for your session, this serving could prove way too much for some users, so be sure to test out your tolerance levels with lower doses to begin with!
Unfortunately, however, it may as well just contain caffeine as the other key active ingredients, such as creatine, beta alanine and l-citrulline are included in quantities way under scientifically optimum doses. That means these ingredients are simply not going to do what ProSupps say they will. As a result, you may as well buy yourself a pure caffeine supplement because it will cost you far less money and do pretty much an identical job to this Mr Hyde pre-workout!
How do you take Mr Hyde pre workout?
As a dietary supplement, mix 1 scoop Mr Hyde with 8 oz of cold water. Consume 15 to 30 minutes before exercise. Do not consume Mr Hyde within 4 hour prior to bedtime and don’t take any other products that contain caffeine or any other stimulants while taking Mr Hyde.
C4 pre-workout side effects
There are a number of potential side effects associated with consuming a pre-workout supplement, most of which are related to any stimulant ingredients included, such as caffeine.
High doses of caffeine can cause nausea, vomiting, diarrhea, and the jitters but is considered safe at doses as high as 400 mg per day. Given that C4 contains a fairly moderate caffeine dose of 150 mg, it is unlikely to cause any major side effects, other than to those particularly intolerant of stimulants.
The moderate dose of beta alanine and creatine nitrate are again too low to be of any concern as to the side effects associated with both of those ingredients.
Is pre-workout just caffeine?
No. Or at least it really shouldn’t be. Most pre-workout products contain a blend of nutritional supplement ingredients with the aim of boosting your performance during a workout.
The vast majority will contain caffeine as this has been proven to be one of the most effective ingredients when it comes to increasing focus and energy for training purposes. However, a pre-workout will often contain other active ingredients designed to boost endurance, increase strength and lean muscle mass gains and even give the user an aesthetic muscle ‘pump’.
