Very very good
This does exactly what it says. I am usually skeptical of anything new. Gave it a try and boy am I glad I did. Great energy boost and impressive pump. Will buy again.

Good product
Ive been taking this product for about 3 months and out if all the pre work outs i have tried this one is by far the best. No matter how tired I am, this gives me the boost I need to get a good work out started. I start to feel it almost instantly. It is a little expensive but well worth the cost and the supply last a decent amount of time before you need to order more. I have recommended this product to 5 other people and they have all given me the same feedback. Good job, great product

solid pre workout
Grape Jekyll and Lemon Ras Hyde. Great tasting. Mix well.

I use a full scoop of Jekyll for every workout and when I need an extra boost I throw in a half scoop of Hyde.

Jekyll and Hyde
Just received these today and used them for the first was Leg day. I used 1 full scoop of Jekyll and a 1/2 scoop of Hyde...that gave me about 310 mg of caffeine combined. The only other pre-workouts I have experience with are Cellucor C4 and DS CRAZE. I looked up the caffeine content in these other Pre Supps and found that C4 has 135mg of caffeine while CRAZE only has 80mg per serving...these numbers came form a 3rd party website so I can't confirm if these amounts were correct. The caffeine in Jekyll and Hyde, however, is clearly marked on the label. In my experience, C4 leaves a little to be desired and I feel more of the beta-alanine than the effects of the caffeine. I prefer CRAZE to C4 even though the caffeine per serving is much lower and it contains no beta-alanine at all. But in my experience it gives me serious mental clarity and focus...I'm actually not a big fan of beta-alanine...I really don't like the tingles, but anyway. This Jekyll and Hyde combination puts both C4 and CRAZE to shame. The beta-alanine tingles didn't seem as severe to me as it does with C4...and the 310 mg of caffeine, the way I combined the two, gave me a serious energy "buzz". I will stick to this 1 to 1/2 ratio until I build up my tolerance to the amount of caffeine. Today was leg day and I absolutely killed it. I do leg press instead of squats. Usually I will do about 4-5 sets. Today I did 8 sets and I felt absolutely amazing afterwards. The best way I can describe the feeling I had afterward was that my legs felt full and STOUT as F'! Usually my legs feel a little wobbly and like jello. Tomorrow is Chest and Arms and I can't wait! Get yourself some Jekyll and Hyde! All the hype is TRUE.

Best stuff ever
This stack is probably the best pre-workout I've ever tried. At first I just picked it because of the cool name, but now I'm hooked after using it. It a has great pumps and gives you a good constant energy level. I love the flavor and every time i open it up at the gym people are always asking what that yummy fruity smell is.
October 27, 2013
Great pre work out.
If you're looking for a great pump, and no crash. This is the product for you.

Pro Supps Dr. Jekyll & Mr. Hyde
Amazing pre-workout powders and i take both at the same time and its perfect for me.

Jekyll + Hyde
Tastes great...I have a high stim tolerance (need 3-4 scoops of C4 to feel the same as this) and this got me into the gym those days that I just wanted to stay home and sleep after a long work day.

is mr hyde a good supplement to include in a weight loss plan?
german s on Nov 19, 2013
BEST ANSWER: Since you are about to start cutting back calories your energy will be low on some days... This is a great pre workout stack but be careful in assessing your tolerance to caffeine... This is a highly potent combination when used together... They taste great and should do the trick to get you through your workouts.
Do you recommed this for a beginner? Never taken any thing like this, only been working out on a regular basis for a few months. Looking at using both.
A shopper on Jul 16, 2013
BEST ANSWER: I wouldn't reccomend this for a beginner, this is the most powerful preworkout I have ever taken! I would start out using something like C4 or Nano Vapor. That will do the job plus some for someone just starting out. I would only recommend this product if you have been using preworkouts for a while and don't feel them anymore, or you have a super high tolerance to caffeine and cannot feel any preworkout you have taken. Hope that helps!
which flavor is a good combination for jekyll and mr.hyde?
A shopper on May 8, 2013
BEST ANSWER: I use watermelon and blue raspberry and its terrible - I just throw it back. The watermelon is really good so i'd avoid combining it with blue raspberry. I've been lifting for close to 10 yes now and I've never used a better pre-workout so enjoy!
I am in the military looking at using this product. I am not sure if there is anything that is banned in this or not. Does anyone know if military can use this or not?
A shopper on Nov 6, 2013
BEST ANSWER: jeckle n hyde will give you plenty of pump n big drawback....very hard crash...this is not only from me..others that I kno experienced the same VERY HARD CRASH! as for if it contains anything that is banned...if so, I don't believe that tiger fitness would sell it if that were true
What is your preferred flavor combo?
Levi B on Apr 25, 2013
BEST ANSWER: I got the fruit punch flavors for both, they were good, but apparently the lemon razz flavor is really good
Am i suppose to mix these two together ?
A shopper on Aug 10, 2013
BEST ANSWER: Hyde is high energy with some muscle pump. While Jekyll is high muscle pump and low energy. You can take a scoop of Hyde alone, or a scoop of Jekyll alone. Both very effective. But my favorite combo is 1/2 scoop Hyde with 1 full scoop Jekyll. 1 full scoop of both is 520mg caffeine which is generally overkill. But 1/2 scoop Hyde and 1 scoop Jekyll is 310mg. Great energy and great pump! Best of both worlds. Hopefully helpful
Been taking this products for a week straight, How many more weeks should I take it before I need to cycle or you don't need to cycle this products?
yousif m on May 12, 2013
BEST ANSWER: Well if your using it everyday during the week I would probably go 2 weeks on 1 week off, when I used it I was only taking it 3 days a week, and two days off aswell as the week, so I used both tubs until finished and then went off it for 2 to 3 weeks then got some more, hope this answered your question :) train hard mate
stack together?
A shopper on Nov 26, 2013
BEST ANSWER: I like them stacked together I do however use a little bit less of each since they both collectively have around 500 grams of caffeine.
I have the Hyde and like it alot. I just started working out and don't know that much about the JeKyll. I'm a woman so is it ok for me to take that one?
A shopper on Jun 25, 2013
BEST ANSWER: Honestly it completely depends on the type of results you want. Hyde is made so that you have more energy to workout with. The reason that there is a large amount of caffeine in it. However, Jekyll is made more for its focus enhancers and its pump. Pump is the feeling where your muscles swell up after a workout. It causes muscles to grow faster and in more volume rather than tone. Jekyll also contains a small amount of creatine that will also assist you in gaining muscle and weight in general. So in effect if gaining weight in muscle or weight in general is acceptable or even ideal for you then by all means Jekyll is the way to go. The way Hyde and Jekyll work together is awesome. I highly recommend the stack but make sure you are prepared for possible weight and muscle mass gains.
How do i take these supplements together?
A shopper on Jan 25, 2014
BEST ANSWER: Hyde is 419mg of caffeine per scoop, while Jekyll is 100mg per scoop. You can really use any combination of the two so long as you keep the total caffeine below 450-500mg. And if you're sensitive to caffeine or don't consume it often I'd aim for less than 350mg. I've found for me it's best to use 1/2 scoop of Hyde and a full scoop of Jekyll. Roughly equates to 310mg caffeine and gives a fantastic muscle pump. Best of all worlds! Be safe and enjoy one of the best pre-workout combos out right now.

how is this compared to c4, I workout 5 days a week and heard about this and am looking for some help to know if this is a good move?
Dan Couch on Sep 12, 2013
BEST ANSWER: I personally have not used C4, rather I have tried out, NOExplode 2.0, Assault, and Jack3d and I must say that the Hyde mixture is very strong.

I typically do 6 days a week for 1-2 hours and when you take Hyde you get in the gym feeling like it was a "5 scoop kind of day". As the packaging says Jekyll is less potent, I found it good for leg days as Hyde sometimes gave me gut rot that Jekyll didn't.

Hope this helps overall it is an awesome product in my opinion.
What's the difference between this supplement and all the rest that claim to do the job???
A shopper on Jul 24, 2013
BEST ANSWER: This gave a great boost pre-work out. If you mix the two half and half it gives a major pump.

I used NO Explode and JackD. After a while they stopped giving me the desired pump. I switched to this product and have been satisfied with the result.

I live in Sweden and i want to buy Dr.Jekyll and Mr.Hyde..

I just want to know if its illigal to ship over to Sweden and if so, will it be stoped on the way here?

what kind of shirt is it?
RUkie on May 9, 2013
BEST ANSWER: XL Pro Supps White T-Shirt at this time.
I've bought this stack twice, very happy with it!
The first time I bought it, the free shirt was a black tigerfitness shirt with a tiny prosupps logo on the back. The second time I bought it, the shirt was white and was just a nice legit prosupps shirt. Although I love both shirts, my question is, how much longer will the stack come with the white prosupps shirt?
A shopper on May 2, 2013
BEST ANSWER: It will last for as long as we have the promotional shirts. Once they run out, we will probably be done with the offer.
