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. 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.*

I’ve tried ALL the popular brands out there including Jym about a year back. After little thought I made the choice to go back to Jym right after the Tangerine flavor came out which is by far the best flavor to me. If I had to describe the PreJym in one word it’s “Smooth” Plenty of power with none of the jittery-ness

Have used different pre workout drinks in the past...confident in the JYM products to know exactly what I am getting every time. Have had a few questions about the product and have been answered by the creators themselves, not by employees hired as customer service reps - that, in itself, makes this brand tops.

It does what it says on the tin. It’s got what you need in proper doses to get through your work out. I’ve been taking the pre jym for more than 4 years never had any problems only result. All flavours for me are tasty 😋, as most important are the ingredients. Just follow the instructions on how to take it and you good to crack the most brutal workout. Also even on days off non training you can take it as refreshing drink instead of fizzy drinks. I’m 49 years old I take all jym line of supplements and never had any problems only results, gains, stronger and liner. To give an opinion on this supplement and see results you need to be consistent taking it and not just in a week or month.
