Pre Jym is the Best!
My personal opinion is this is the best ore workout out there. I love the results I get while I workout. The taste is amazing. Every flavor is great, my favorite is Refreshing Melon. The best part about it is it’s everything you need in one serving. There is no need for other supplements it has it all.

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.
What's the best pre Jym flavor?
A shopper on Jun 19, 2018
BEST ANSWER: Strawberry pineapple is the best flavor hands down
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.

brandon d on Dec 17, 2018
