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.

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.*

Best preworkout on the mark in my opinion! Love all of Jyms products. Didn’t personally care for the Raspberry Lemonade, but that’s solely flavor related.

Pre Jym is a great pre workout option. I have used a gamut of pre workout supplements over the past 7 years, and Pre Jym has become a favorite. Rainbow Sherbet all the way.

Best tasting pre workout ever. And whatever is in this stuff, I'll get 60-90 minutes into my HIIT workouts and all of a sudden POW, I've got more energy than when I started. Never had that effect with any other pre workout or supplement. A+ from this user.

This is by far my favorite flavor! Just the right amount of sweetness. Been using Jym products for a solid year and I’m very happy with the progress in the gym and on my physique.

Great product. Very versatile. Can be used as an energy drink, or pre workout. No crazy chemicals that need to be cycled off. It's the closest product to buying individual ingredients and mixing your own variation. Flavor wise I seem to like the less popular Refreshing Melon, originally used Raspberry then Sherbet. Will try other flavors as long as this product does as it says. After years of experience, I have seen a lot of changes in trusted brands. Stack this with other Jym products like Alpha, ZMA, and Shred for quicker and different program results. [Shredding, Bulking, Endurance...]

It doesn't mix well and the flavor that I had tasted gross. It foams up a lot when shaking.

Dr Jim isn’t kidding when he says his pre-w/o has all you need for a stiff kick. You can tell from the portion size alone that it’s packed with all the goodies, with the biggest scoop I’ve seen and the most well rounded panel of ingredients. The flavor is equally strong but it’s pretty good, and mixes well in a 700 ml shaker if you want it during your workout.

Flavor is good, the best part is the level amounts of energy you get, I don’t spike then drop during the workout! I totally would recommend this pre workout!
