Pre JYM™ Changed

The Supplement Industry

Upon introduction in 2013, Pre JYM ushered in an era of transparency and became known as the world’s first high-performance Pre-Workout supplement. Pre JYM was designed by renowned exercise and nutrition scientist Dr. Jim Stoppani to allow dedicated athletes to unlock the critical elements to fitness success: motivation, performance, transformation, and growth.*

13 Hand-Picked Ingredients

Pre JYM includes 13 ingredients that complement one another to prime the body for intense workouts, making it a complete pre-workout supplement. When it comes to supplement formulation, it is important to understand how synergies work. Certain ingredients work well when combined with other ingredients. This is where many supplement companies fall down. with PRE JYM, I personally selected these 13 quality ingredients that have fueled my workouts and those whom have applied my advice for years. As a scientist and bodybuilder, I understand how to combine both science and real use to attain real results.

No Proprietary Blends

Look at the Supplement Facts panel of your current pre-workout product and you'll likely see "proprietary blend," "pump matrix," "performance blend," or other catchy name in lieu of listing all ingredients and precise doses of each. Some supplement companies want you to think this means they've created a special concoction that magically delivers unique results. Because this blend is so amazing, they have to keep the amounts of each ingredient secret so that no other company steals the formula.

Truth is, proprietary blends typically serve a different purpose: They allow companies to hide how little of each ingredient they've actually put in the product. These ingredients are often cheap, ineffective, under-dosed, or all of the above. Pre JYM doesn't use proprietary blends – never has, never will. All 13 ingredients with exact doses that are clearly listed on the label. You deserve to know exactly what ingredients, and how much of each, are in the product you buy. Proprietary blends serve the purpose of hiding what’s in the product, plain and simple.

Gaining muscle helps support all goals – strength, physique, weight loss, and overall health and wellness. Pre JYM will spearhead your growth efforts with nutrients, not stimulants, that ignite protein synthesis to help you build more lean muscle.*

Nutrients vs. Stimulants

Your pre-workout should contain real nutrients that deliver real results, not various stimulants that do nothing more than get you temporarily "amped up." The Pre JYM formula is based on amino acids (the building blocks of protein) that fuel your muscles and provide "clean energy." The only stimulant in Pre JYM is caffeine, selected for its performance-enhancing benefits, not simply to give you a jolt. Pre JYM changed an entire sports nutrition category when it launched in 2013. Before then, pre-workouts were loaded with stimulants you couldn’t pronounce that gave you the jitters and little else. Stimulants provide a temporary boost. Nutrients, on the other hand, are the foundation for real gains in strength, muscle-building, endurance, and overall performance. Pre JYM was the first ever true performance pre-workout, and years after changing the industry, it’s still the product smart consumers choose to fuel their muscles, and their goals, with actual nutrients.*

No BS, Just Science

I've been studying nutrition and supplement science both in the lab and in the gym for decades. I’ve done the research, and I’ve converted it into real results for millions of real people just like yourself. I began educating hard-training men and women worldwide through the pages of Muscle & Fitness, FLEX, and Muscle & Fitness Hers magazines before finding a home for my programs, articles, and videos here on, as well as my own website I developed Pre JYM back in 2013 to take the results to the next level and provide myself and anyone else training hard in the gym the ability to access, in one bottle, the best supplement ingredients to help build lean muscle, torch body fat, improve strength, and boost performance.*

Great pre-workout powder. Be sure not to drink too fast and drink plenty of water after. I like mixing mine with ice. Pineapple strawberry is my favorite.

I don't know why Refreshing Melon doesn't get no love! This is the only flavor I buy for myself. The other flavors are good too but this one is my fave. On top of having the best ingredients backed by science this flavor is, well refreshing...

Tangerine 10/10. Great taste and the only pre workout I have ever taken that didn't give me the shakes. I would recommend trying any of Jym's products.

JYM Pre is by far the best Pre I've ever used. I've used BSN and ON products before, but they don't compare to JYM's.No terrible tingling feeling and I get a real good pump from it. 1. Orange Mango (tastes exactly like tropical trident gum) 2. Pink Lemonade 3. Tangerine (taste just like one) 4. Rainbow Sherbet (tastes like a handful of original flavor skittles. It’s awesome but sweet!) 5. Grape Candy (tase just like Welch’s grape juice) 6. Cherry limeade (tastes like red starburst) 7. Raspberry Lemonade (real tart) 8. Pineapple strawberry 9. Strawberry Kiwi 10. Refreshing melon And I haven’t tried black cherry

  • 4 Rainbow Sherbet

This is a really good working product. Very high energy, pumps, everything you want in a pre workout supplement. But the rainbow sherbet is disgusting. I have bought or sampled 15 different pre workouts from repubatle brands and this is the worst tasting of anything I have tried in 10 years. If you can look past the taste, this is a first class pre workout. Maybe the other flavors are better. Lesson learned, do not buy the bigger size tub on your first try.

I have tried several preworkouts and this is by far my favorite. Great energy without the "shakes" and amazing results. I'm just a huge fan of Jym overall. This was not a paid promotion.

Exceptional product. The new Grape Candy flavor is OUTSTANDING. The fact that it went straight into the 30 serving tub told me in advance that this would be a homerun. Jim and team has once again knocked it out of the park. He stands behind his brand, is TRULY the face of the organization. I am a JYM customer for LIFE!

Pre-jym is my go-to. I also liked the old Muscle Pharm Black, but they discontinued the kind I liked. Pre-jym definitely has a caffeine punch, so I’ll often just use 2/3 scoop if I’ve already had a cup of coffee in the morning or am taking it later in the afternoon. I’ve tried a bunch of the flavors, and my old standby used to be orange mango or tangerine (they are both very good and taste very similar, in my opinion). However, the new pink lemonade knocked it out the park. Maybe the guy below complaining about it tasting like garbage and not working got a bad batch? Because I’m not a bot and think it tastes just like Crystal Lite without the weird aspartame chemical aftertaste. It was a perfect balance- not too sweet, not too tart (mixed w/ about 18oz of water. I have to use more water for orange mango or else it’s too sweet for my liking.) Obviously taste is a subjective thing, which how so many people end up with ugly spouses. But in this case, the pink lemonade is awesome.

I love this pre work out. I have been using Pre-Jym for over a year now. I have had all the flavors, Pineapple Strawberry is my favorite but this new Grape Candy tastes like cranberry juice, extremely tart and bitter, almost hard to drink.

I dont know if bots are reviewing this product or americans taste buds are whack. I bought the jym pink lemonade because it is the highest rating. Boy me and my wife were suprised she could barley drink it and i had to chug it because it was awful. The pump was equivalent to a decaf coffee (placebo 70$ after shipping and its going in the garbage. Another thing. I could have swore my dog took a **** on my floor but realized it was the after taste of this garbage in my breathe.
