Below we take an in-depth look at Mr. Hyde, to see whether this potent pre-workout mix has the right balance to provide the right energy for an intense, muscle-building gym session.
Mr. Hyde is a strong, pre-workout sports supplement that is designed to help customers to build more muscle and achieve their highest potential in workouts. With a formula packed with caffeine, this mix provides a huge dose of energy and increased blood flow for muscle building. It also comes with a range of side effects, including a pins and needles sensation, and more serious respiratory or caffeine-related symptoms that have required hospitalisation on at least one occasion.
Mr. Hyde is produced and sold by ProSupps, a large American supplement manufacturer specialising in strong bodybuilding products. ProSupps is a large and very successful company with an international presence, although one that has recently been warned by the FDA for unprofessionalism and poor customer service.
In the FDA’s recent warning letter to ProSupps (dated February 2017), the company was criticised for its lack of quality control policies (resulting in some products being sent out with the wrong labels). The FDA also complained that the company failed to respond to serious incidents of Mr. Hyde making customers ill, and still has no returns policy at all.
Mr. Hyde is unfortunately quite heavy on the side effects. Most commonly, customers should experience a noticeable tingle (a feeling like pins and needles) on their skin when first taking, a side effect of beta alanine. Most other side effects are related to the caffeine, and to a lesser extent, the Yohimbe contained within the mix.
Mr. Hyde can cause trouble sleeping, rapid heartbeat, anxiety, restlessness, headaches, chest pain, trembles, a ringing in the ears, stomach problems, nausea, frequent urination and other effects.
Readers should know that Mr. Hyde has caused serious breathing problems in the past, and has caused at least one customer to be hospitalised. Any customer that is overweight, sensitive to caffeine, or is undergoing treatment for any condition MUST check with their physician before taking this product!
Prices vary significantly for this product depending on where you find it. In general, the standard 228g tub (with 30 servings) should cost around $27-$30, with the cheapest prices being found on Amazon and other budget retailers of supplements. The official ProSupps likely represents the upper limit in terms of price, with the same tub costing $59.99. Mr. Hyde is available from almost every online retailer and can be found in thousands of stores around the world, so be sure to shop around to find the very best deal!
This product is very popular on places like bodybuilding.com, which is an indicator of its potency and effectiveness. As a customer base, bodybuilders seem to know their stuff, and the group seems to be unanimous in their judgement that Mr. Hyde is a strong and effective mix that delivers what it claims to for a relatively good price.
Although customers should expect a strong boost of energy and great muscle-building potential when taking this product, they must also expect some serious side effects. The caffeine contained within this mix is significant, and Mr. Hyde has been known to cause serious problems in the past. The product is in fact not recommended for anyone who is more than 15 pounds overweight due to the pressure it puts on the body, and customers must take real and serious care to ensure that this product is suitable for them. Customers would also be well-advised to cycle this product with something less strong, to ensure that the body doesn’t suffer under unnecessary strain.
More worryingly, ProSupps has not acquired the reputation for professionalism that it needs to sell a product that is this potentially dangerous. The company has been found to mislabel products accidentally, and has been criticised by the FDA for its quality control. ProSupps has no returns policy at all, and has failed to respond effectively to reports of Mr. Hyde making some customers seriously ill.
In short, Mr. Hyde seems to be the preferred pre-workout supplement of choice for many informed bodybuilders, but we still feel that the serious side effects warrant serious care when choosing this product for yourself. It’s not really possible to recommend it due to the manufacturer’s current carelessness and the potential health risks it poses.
We do not recommend Mr. Hyde to our readers.
Mr. Hyde is a pre-workout, muscle-building supplement designed to support long-lasting athletic performance. Marketed as an extremely potent mix, Mr. Hyde is designed to be taken sparingly, with the manufacturer advising ‘cycling off’ the product for 2 to 4 weeks at a time to allow the body to recover from the effects. This advice is likely related to the extremely high doses of caffeine contained within the formula.
This strong product is produced and sold by ProSupps, a US-based manufacturer of pre-workout and muscle-building powders. ProSupps appears to be an extremely successful and well-known brand, with distributing partners all over the world selling ProSupps products online and in-store. Despite its impressive reach, ProSupps has often been accused of unprofessionalism; in February 2017, the US Food and Drug Administration (FDA) officially warned the company over its poor standards, particularly focusing on its lack of complaints, quality control and returns policies. The company can be contacted via the contact details supplied near the bottom of the official website.
Mix one scoop of Mr. Hyde with 8 oz. of cold water. Consume 15 to 30 minutes before exercise. Do not consume Mr. Hyde within 4 hours prior to bedtime. Do not take other products that contain caffeine or any other stimulants while taking Mr. Hyde.
On the official ProSupps website, Mr. Hyde is mainly advertised as an energy-rich pre-workout formula that can help athletes achieve their maximum potential. The various ingredients are said to help with building muscle, improving mental focus, and enhancing endurance. The following key benefits are listed on most product pages for Mr. Hyde:
Many of the ingredients contained within the mix are highly effective at what they do. All of the ingredients contained within the Strength Matrix should help to build muscle and improve performance in the gym, and the huge doses of caffeine will help to give a massive boost of energy. The Intensity Matrix is perhaps the least impressive; we believe that users may not notice a huge increase in their focus/attention levels, but will likely be impressed by the significant boost to their athletic performance. The available customer reviews seem to support this, as very few customers claim that the mix doesn’t work (with most claiming that it is very potent).
The ingredients used in Mr. Hyde are listed below. The ingredient quantities listed below are correct for 1 scoop of powder (7g), which is equivalent to 1 serving according to the manufacturer’s recommendations.
Strength Matrix 4.5g
Caffeine Matrix 419 mg
Intensity Matrix 629 mg
Mr. Hyde is known for its side effects, and has in the past hospitalised its customers or caused serious side effects (such as breathlessness when not exercising). These serious effects are related to the potency of the mix, and the product should be avoided by anyone who is sensitive to caffeine, who is overweight in the slightest, or who suffers with any of the conditions listed in the ‘Caution’ box below.
Many of the most common side effects experienced whilst taking Mr. Hyde are related to the high caffeine content. In overconsumed, caffeine can cause insomnia, rapid heartbeats, nervousness, restlessness, headaches, chest pain, shaking and a ringing in the ears. One other extremely common side effect of taking Mr. Hyde is tingling and pins & needles, an effect associated with beta alanine.
Although the dose contained within this mix is low, Yohimbe has been associated with countless side effects over the years, including stomach problems, high blood pressure, dizziness, tremors, sleep problems, anxiety, nausea, bloating, frequent urination, drooling and sinus pain. A minority of users may also experience temporary side effects as a result of the high Vitamin B3 content, which can cause harmless flushes, and mild stomach upset and diarrhoea.

There are thousands of customer reviews for Mr. Hyde available on the Internet, with the vast majority of customers generally very positive in their appraisal. The consensus appears to be that the formula is very effective, although some claim that it is not as strong as others say.
This works so much better than the pre-workout I was using before. I had to take two or three scoops of my other because it just wasn’t giving me the kick it was supposed to. With this one I get the energy I need with one scoop and it keeps me going throughout my whole workout. I’ve tried so many different brands and kinds and this is definitely one of my favourites. It tastes great as well!
Please note the caffeine content in this pre-workout. For anyone looking to get tunnel vision from caffeine this is the product for you. Does your body go numb? Yes … but the GAINS received are incredible. If you’re looking for one continuous heart beat for your workout, then this pre-workout is great. This pre-workout certainly helps get more reps and more weight.
Great product very strong recommend starting with a lower dose if not used to pre-workouts as this one will hit hard. Gives great energy through the workout with no crash later in the day so it’s a must if you want to push your workouts to the extreme.
Not a real good pump, not a lot of extra energy. I don’t know who else reviewed this, but I did not get the bang for my buck as some other people did.
It’s alright. I weigh 140 pounds I don’t feel really anything I wait 20 min. but idk it doesn’t affect me that much and fruit punch is awful absolutely the grossest thing I’ve ever tasted, orange burst is pretty good though but overall it’s alright I don’t consider it amazing but everyone’s body is different.
Not only does ProSupps not provide a money back guarantee, they don’t seem to provide any kind of returns policy whatsoever. They were actually pulled up on this issue in early 2017 by the FDA, who complained that the company has no procedure for receiving returned packages, let alone organising a refund or contacting the customer. This situation may change following an official warning from the FDA.
Mr. Hyde is available from a huge number of retailers, both online and in-store. We recommend buying from a trusted retailer, taking care to select one that allows you to return opened tubs of products for a full refund for any reason.
Mr. Hyde is available to buy online from a number of retailers (including the official ProSupps website, Netrition, Lucky Vitamin, bodybuilding.com, the vitamin shoppe, supplementsource.ca, Amazon, GNC, and Muscle & Strength). ProSupps products can also be found in more than 2500 shopping locations in the USA, Canada and dozens of countries around the world.
Prices vary significantly for Mr. Hyde depending on where you buy it. Customers can buy Mr. Hyde in tubs containing 5 servings, 15 servings, 30 servings and 60 servings. A standard tub of 30 servings (228g) costs around $27-$30 (the cheapest outlet we found was Amazon at $27.36 for 228g and free shipping for orders over $35 – you may be able to find better with a bit of research). Buying directly from the ProSupps website seems to be the worst option available, with a 30-serving tub costing a massive $59.99 (free shipping only available on orders totalling over $99).
