Average all in all
I like the preworkout. It’s not too crazy powerful but it gets the job done, even with just half a scoop for me (I’m 120 lbs and 5 foot tall). The only thing I would say negative about it is that you really can’t taste the strawberry, so it’s basicaly just kiwi flavored, not bad, but I would prefer strawberry kiwi. But it doesn’t have the side effects such as super bad jitters or diarrhea midway through your workout.

Good Pre
I like it because it doesn't have a lot of extra stuff you don't need.

I’ve notice everyone saying this pre workout basically tastes like ass, but I got the strawberry kiwi and i think it tastes pretty good (kinda sour tastes). This gives me the boost of energy I need at the gym and really helps me feel like I can lift heavier. It’s helped me through my 5am workouts and usually I don’t even get out of bed until 8/9. There’s creatine in it so drink lots and lots of water. I’ve felt kinda sick to my stomach a couple times because I wasn’t consuming enough water. It does makes you feel kinda itchy but other than that, amazing!

It works okay. Tastes awful and way overpriced though

Impressed with science behind it, but won’t order again.
Serving sizes too big. Not practical to have to add that much liquid to properly dilute it. Also, flavors are so-so, some not good.

Tastes good but needs improvement
It tastes good but it felt heavy in my stomach during my workout.. i needed to water it down to make it easier to drink. I did like the energy I got from consuming this product & felt I got a good workout

Active User for Years
I have been using Jym Supplements since 2014 and I can say confidently that they beat out every other supplement in the industry. The only other preworkout that can maybe compete with this is NO2, but that one almost gave me heart issues. Occasionally I have to go off of this preworkout for a month just because it is that powerful and I begin to become numb to the kick. Having to mix it with more water, I think, is a bonus because then you're hydrating more. Everyone complaining about the mix time is just impatient and can't properly plan out their supplements and workout timing.

Terrible taste
Tastes like battery acid.

Not for me
I bought this one because it had strong reviews but for some reason it just makes me sick to my stomach for about 2 hours. Wish I could get my money back.

What is the difference between your GNC Jym Pre-workout compared to what BodyBuilding has on their site? I see the flavor options are different, as well as a few changes to what ingredients are described. Thanks for your response!

Can you mix your preworkout the night before and drink first thing in the morning?
A shopper on Jul 1, 2018
BEST ANSWER: Should be able to. It’s recommended to mix it for about 30 minutes before drinking it and drinking within 15 minutes for max results. Also all of the above 30 minutes before training
