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.

Bolt Icon Energy*
Focus Icon Focus*
Runner Icon Stamina*

Performance*

Get stronger in the gym and train harder and longer. Pre JYM will help you do it with ingredients that promote energy, focus, and stamina. Set PR’s in all areas with Pre JYM as your high-performance training fuel.*

Growth*

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 Bodybuilding.com, as well as my own website JimStoppani.com. 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.*

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.

The key to making the perfect PreJym drink is to use about 24oz of water. Anything less and it’ll be too sweet. Had been a strawberry kiwi lover for years until I came across grape candy. I’ll be going back and forth between the two flavors. For over 3 years, PreJym has been apart of my daily routine. I look forward to making each PreJym as it gives me the daily boost I need either for my days outside of the gym or when I need to hit the weights hard.

After taking a look at this stuff for a while, I decided to finally pull the trigger. I was primarily an ON AmiN.O. Energy guy prior to this. I’ve always been hesitant to wade too far into the pre-workout arena ever since I had a bad reaction to the old formulation of N.O. X-plode. I normally don’t “try half a scoop to assess tolerance,” but in this instance I did only 3/4 of a scoop the first time out of an abundance of caution. The first time I used it, I mixed it with about 16oz of water and it was pretty intense, but in a good way, save for my slight paranoia of having a bad reaction. Day 2, after reading some stuff online decided to move up to a full scoop but mix it with more water, as this supposedly prevents it from hitting too hard. Once I did that I found it to be a very smooth, balanced, energizing experience. I’m 38 so the main fight I have now is with muscle fatigue later in my workout; with this stuff my last set is almost as good as my first. Additionally, the Raspberry Lemonade Flavor is so good, I’m tempted to take it on off days, (which they tell you to do to keep your creatine levels, but I go a different route). All in all, this provides a much more measured experience than I expected, but in a good way; it gives me the energy and focus to power through my workout without feeling jittery, feeling like my heart was gonna jump out of my chest, or any of that type of stuff. Granted, if that’s what you’re looking for, I feel like mixing it with the lower range of recommended water will probably get you there; I prefer to mix it with closer to 28oz. The only downside is that I do typically experience a crash later in the day, but this is also the only caffeine I take on the days I use it. I will definitely stick with this over the AmiN.O. Energy moving forward; despite the low flavor rating, I think Black Cherry is next.

The product itself may be the best one out there haven’t tried them all but more than 10 yes and by far pre jym top of the line by a lot. Grape candy taste like a jolly rancher or grape juice very refreshing has a strong grape profile. Will definitely keep in the rotation yet to try the tangerine the only one still pending. But grape candy i still think it’s a one step down from the classics cherry limeade and raspberry lemonade still the GOAT of all the them.

Really impressed with the execution of Grape Candy. Most of the line tends to be on the sweet side but this is a little more balanced. The taste being in the realm of Welch’s Grape is very accurate. Mixing flavors works well also. Orange Mango/Black Cherry and Orange Mango/Grape Candy are two of my favorite combos.

If you like grape flavored candy, you'll love the new flavor. I love the clean energy I get when taking it. I never get the itchiness that I got with other preworkouts.

Pre Jym is by far the best pre workout on the market in my opinion. It is a product that you can use for any part of the day. I often use it in the morning to help we wake up and get going for the day. If I were to only purchase one Jym product, Pre Jym would be that product. Pineapple Strawberry and Orange Mango are my two favorites, but Grape Candy is close behind. I just wish the Grape was a little more sour to me. I like a sour grape flavor, but this version is pretty good. I found that I liked it more the 2nd and 3rd time versus my first taste test.

Jym Pre-Workouts and Post Workouts are delicious and true to their advertised flavor. Pinneapple Strawbery is my GOAT but I really do like every flavor that I have tried - and have tried nearly all.

I was hoping this was sweet but not too sweet and the doc hit it spot on! Like drinking slightly watered-down grape Kool-Aid! So tasty and still gets me the fire for the workout!
