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!

Great Pre-Workout
This is a great pre-workout and Jim Stoppani is the man! Great ingredients and proper dosing are key and this pre-workout gets it right. Highly recommend his workout programs on although don't buy this from as they are selling an unauthorized older version of this (as they are currently in a lawsuit against each other)! I use this for most of my regular workouts (1-2 hours with cardio and weight training). I prefer C4 for quicker workouts (30 minutes to 1 hour) and Performix for longer workouts (2-3 hours+).

Best PWO in the world
Most people aren't educated on supplements, and especially pre-workouts. Most people think pwo is supposed to get you super jacked up and jittery and shaky. This product does not do this. What it DOES DO is provide all of the ingredients you need at the proper doses (along with Post-Jym). You will see increases in muscle strength and endurance, and you will experience extended endurance for an entire workout. I usually lift and then do cardio, and even when I'm done with my cardio I still feel like I can do more. You will also be more focused. I was taking a math test before, got stuck on a problem, started sipping pre-jym and in about 5 minutes I remembered how to do it and ended up with an A on the test. This happened TWICE. It's the real deal, just give it a shot. Measure the scoop (25g) with 21-24 oz of water, that gives the best taste

Amazing Pre-Workout
I have tried them all and then found these JYM products. I love the black cherry. The taste is amazing. We tried the Natural Flavor and not a fan, But this black cherry will be my go to pre workout. Amazing.

Good stuff! Flavor is alright
The product as a pre-workout: great!

Definitely gets me pumped before my workout. No jitters, a little bit of tingling in the extremities, increased focus and motivation, increased energy (for both weight lifting and cardio).

The product flavor: alright.

I've tasted a lot of really NASTY pre-workouts, this one beats most of them. Although, if you take the full scoop and recommended amount of water, the flavor is strong.

I'd definitely recommend trying this one!

Get your BEST workouts with pre Jym!
I switched to jym pre workout because I was tired of feeling like a crack addict when on other pre workouts! I hated the jitters, the itching, the HR spike! A store employee recommended jym to me and I'm glad she did! Instead of providing a sugar spike like other pre workouts, Jym fuels your body with the supplements you need to have a killer workout, WITHOUT THOSE UNNECESSARY JITTERS! I've had my absolute BEST workouts taking Jym! The larger tub lasts a quality amount of time, even though the scoop is pretty big compared to other pre workout servings. 10/10 would recommend! P.s. black cherry is the way to go!

The pre jym strawberry kiwi was awesome, the taste was great, as well I had intense focus, some times I would take it 10 mins before my workout and sip on the rest through my workout, maintained focus as well as delivered pumps which lasted even after my workout... I just put in my order the watermelon pre jym can't wait to try it..

It's NATURAL so don't expect sweet as candy!
I actually like the Natural Island Punch because it's not sickly sweet like most preworkouts on the market these days. There are enough artificial sweeteners in everything else that I appreciate the lack of them here, and since I mix PreJYM with ProJYM as my preworkout drink, the tartness of the Natural Island Punch balances out the sweetness from the Pro. PreJYM in general is the best -- all of the power and endurance benefits of a PWO without the crash that many PWOs have due to excessive stimulants. Pay attention to the amount of water it recommends and consider mixing as well.

Won't Find Better Ingredients/Dosing in a Pre-Workout
Hard to find better ingredients in a pre-workout. Doesn't give me as much of a tingling sensation like other pre-workouts but overall I find I have much more endurance for longer workouts with this product. This is Jim Stoppani's official pre-workout offered only with GNC. The one on is being produced unauthorized! Scary! How is that even legal!?!

Best ever.
I'm not sure if there's any other pre-workout out there that uses clinical study based doses, but the results & feel are apparent. My favorite pre-workout of all time.
