JYM Supplement Science

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!

Great product Great ingrediants
Probably the best pre-workout I have used. There are some others out there similar now but they have not given me quiet the boost this one does with a full transparent label and good dosage, and usually I find this one just a little cheaper per serving so it continues to be a win win.

Great product. No complaints.
People complaining how big the scoops are aren't realizing what you are getting. Actual nutrients. You can't condense potent ingredients like other drinks and expect a good result. Most preworkouts don't have bcaas in them, anyone with half a brain knows how important they are in a workout.

Very good flavors, but higher calories
I take this even though it has more calories than other preworkouts in my pantry because it really gives you fantastic energy and less soreness. The extra calories are not BS or filler.

Mommy mine tastes funny...
Great taste with quality ingredients and reasonably priced. Hard to fault this one. If flavor is your #1 all time most bestest importantest factor to determine how good a pwo is, this is not the product for you. Natural Island Punch has a mango-y flavor that is like a sweet tartness with the BCAAs. Some might say bittersweet. Clearly nothing like the cotton candy rainbowsherbert mountain blast flavor I got from that one company and I didn't start sweating and tingling right after drinking like I did with the other brand. All jokes aside, this is my favorite pwo I've tried. I get an intense clean and focused boost that feels well balanced and helps me keep that focus all the way through. No crashes. Excellent Product.

Flavor is great but one major downside
The scoop with this product is huge. Like 3-4 times a normal sized preworkout. Thusly you need 3-4 times the amount of water or it is undrinkable. I needed to consume 30-36oz of water prior to a workout. Everything else about this product i liked but i found it hard to drink all that water before a workout. Flavor is one of the better ones I have had though.

A Lot of Pre
The scoops are huge and require a lot of water to mix. The energy boost is moderate. A single serving of Pre-Jym one must consume is considerably larger than most other pre workout supplements. It gets me out of bed in the morning for workouts before going to work, but it is a lot to have to drink compared to similar products.

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!
Will this be available in Canadian GNC stores?
