JYM Supplement Science
Muscle Growth - Strength - Energy - Mind*

My Guarantee
Inside this bottle is decades of supplement research — from the lab and the gym. As a scientist, I have spent years researching ingredients that will produce results. As a gym rat, I have spent years benefiting from that research. Now it’s your turn. Every ingredient in this formula is in a dose used in clinical studies and my own gym to produce significant gains in size, strength and endurance.* I know it works because this is what I take before every one of my workouts. Let it work for you. Hit the JYM!

PreJYM is hands down the best preworkout. I've. Even using it off and on for 2 years now and it still works great every time. The strawberry pineapple is the best flavor to date!

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!

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!

BEST ANSWER: The products found at GNC are actual Jim Stoppani products!! Nothing else needs said
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!

Can you mix your preworkout the night before and drink first thing in the morning?
A shopper on Jul 1, 2018
BEST ANSWER: You have 3 hours at room temperature, and 8 hours in the refrigerator before the creatine inside pre jym starts to break down
