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.*

This pre-workout has a larger scoop, but didn't pack the punch I've come to enjoy in a pre-workout. It gets the job done for a bit of energy, but didn't give me the "pump feel" that I had seen in the reviews. Worth a try, however I won't be buying it again.

As far as I’m concerned this pre-workout is terrible. Huge scoop and you need at least 16 oz of water to drink it or it’s too thick. Not what I am looking for in a preworkout. Made me feel bloated and slow. Flavor was pretty good.

It works. I’m able to power through workouts. Absolutely no jitters, loss of sleep and no stimulant feel in the gym. It’s a little thick though. I’ve been mixing with 32oz of water and it’s still a bit thick. It’s not cheap, but I will buy again.

Best Pre Workout in the market...hands down! I drank half scoop: no jitters and just the right amount of energy boost. The taste is fantastic - orange mango flavor is the winner. Customer for life!

Have been taking JYM for several years and the newer batches are AWFUL across the board grape being the absolute worst . I am hoping Pink Lemonade ( only flavor i have not tried ) is better. I don't drink pre workout bc of the taste at all, but these are hard to drink and cause heartburn at times. go back to old flavor mix or I will have to find a new PRE

To me it’s the best pre workout on the market. It’s definitely gets the job done. No jitters or skin crawls. The grape candy tastes too artificial for me & tart. I purchased this product quite a few times, switched to Pre Kaged to try it & was most certainly disappointed. Pre Jym is where it’s at

Solid go to pre-workout. My recommendation, try it, and then try to go back to your old one, you'll end up coming right back to PRE JYM.

For anyone who reads this and has saw the comments about the tangerine and grape candy reviews saying they are bad, if u have ever watched any videos on Jim he shows you to out them in ice after about 5-10 minutes of mix in room temperature water. i was not a huge fan of the taste until i did this and they are the best tasting pre workouts i’ve ever actually drank instead of dry scooping! i hope you find this helpful!!

I don't often write reviews for products on bodybuilding - actually never - but this time I made an exception. If you're looking at Jym's products, you know they're quality ingredients, no 'condensed' servings, and expensive but you know what you're getting. The reason for this review is the taste of the Tangerine flavor. It is by far the WORST pre-workout flavor I've had, and I've handled some pretty bad ones. Since has started flavor ratings I rarely ever risk the lower rating flavors which means I'm usually pretty safe, but the high flavor rating on the tangerine deceived me. This legitimately tastes like acid reflex / throwup if you had just ate an orange. Pick a different flavor and hope for the best. Caffeine content is a bit higher than I would like but I knew that when I bought it.

First, the taste is amazing. I used to cringe a little before taking a pre-workout. Not with this JYM product. It mixes really well with water, so there are no clumps sitting on the bottom of the glass. After taking it, it just gave me an extra burst of energy to complete those final hard reps. Plus I felt bigger ( pumped ) as well. Great product!!!!
