Pre Jym Refreshing Melon simply the best!!
Before Pre Jym I had tried 3 other pre-workouts that just to get a good pump going I would have to take 2-scoops. So that would literally make my 30servings go down to 15. With Pre Jym (Refreshing Melon flavor) 1 scoop is enough and I can go hard for 2 hours no joke! Plus it has your BCAAs, Citrulline Malate, Creatine and other good ingredients to help. I would highly recommend this product.

A little on the sweet side but good. I can take a 3/4 serving at 415am before the gym after eating something small. Worth trying.

Love this pre workout and entire brand! Hands down the best! And best tasting!
Highly recommended!!! I bounced all around until finding Jim Stoppani years ago..... never looked back! Amazing results with pre jym plus it's literally the best tasting pre workout I've ever had! You can't go wrong with really any flavor you'd think you'd like, but I suggest trying pink lemonade! My favorite! Tastes just like country time lemonade from the store, you'd never know it was a pre workout by its taste, but you will buy its effect!!!

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!
A shopper on Oct 5, 2016
BEST ANSWER: Nothing is different but the flavors.

can women take this shake?
kelley on Feb 22, 2018
BEST ANSWER: Of course! Go to YouTube and type “jym supplements for females?” A video will pop up with Dr. Jim Stoppani explaining it in detail. Enjoy! Rainbow sherbet is amazing!
Will this be available in Canadian GNC stores?

Can you mix your preworkout the night before and drink first thing in the morning?
A shopper on Jul 1, 2018
BEST ANSWER: Jim says no. After 8 hrs in liquid some of the ingredients become inert. I have done this prior to knowing and it also tastes rank.
why isn't there a 30 serving option for the pineapple strawberry? will they be adding it soon cause ill hold off till then
Rickster on Sep 7, 2018
BEST ANSWER: Its a new flavor so it came out in smaller size to see how it did. Don’t think they have announced if it will be a 30 serving option yet.
Is is for shakes or can it just be added to water bottle?
A shopper on Feb 4, 2019
BEST ANSWER: Its pre workout, mix it with the instructed amount of water on the label in your shaker bottle and drink roughly 10-15mins before your workout
