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.*

I really enjoy this pre-workout, I have used many other pre-workouts in the past but this falls within the top 5 I have had. the only thing I wished it had was a better pump complex, because I feel it lacks just a very small aspect of pump. besides that great product. would deffinantly recommend!

Jym products have changed my life. I have found the motivation to get myself back into the gym and get back into shape thanks to a friend who recommended these products to me as well as the Jim Stoppani training programs 10/10. Thank you Jim Stoppani I'm in the best shape I've been in since my early 20s thanks to your programs and products.

Generally not a fan of pre-workouts with their grit and after taste. I've experienced none of these issues with Tangerine Pre Jym. The flavor is top notch. If any part of your shaker bottle is white, it will stain over time.

So i used this brand exclusively until they stopped producing the natural flavor. Im allergic to artificial sweetners especially sucrolose, it gives me incredible migraines. I was using raw ingredients for a long time (basically salt water in taste) until i found this company and they had a version of this without sucrolose. Then that ONE flavor didn't sell enough so they discontinued it and now im stuck using inferior preworkouts, prejym was the absolute best but im giving a 1 on review because clearly all they care about is money. Seeing that a doctor is begind the whole thing makes it worse because he knows that sucralose has this effect on many people and doesn't offer a natural version because he don't make as much money. Pretty sad.

I’ve never had a better pre workout. It doesn’t get me all jittery before a workout and then make me crash afterwards. I used to have to buy multiple products to get all the ingredients that are in this one tub. I would recommend this to anyone starting out and also to anyone that is experienced in lifting.

I have tried many ore workout drinks and couldn’t take them due to how they affected my heart but with JYM Pre I never have that problem and have been using it for a year now. Plus they taste great and not overly sweet.
