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.*

gives a steady stream of clean energy without any tingles, but i'm having long hours of sleeplessness and must be due to having caffeine and i'm not a coffee person or take any energy drinks so my body is not used to it. taste is good but it rest in mouth until you brush. but the product does what it says.

I’ll only use 2 pre workouts. This one is my preferred PWO. It’s harder on the stomach though. I feel bloated. The orange mango tastes good but it foams up like a soap. The other flavors don’t. Raspberry lemonade tastes good like juice you buy from the store.

While I love the effectiveness of Pre Jym and feel it's well worth the money, I have noticed the flavors with Carrageenan in the ingredients always cause me stomach/bowel issues. So I stick with the ones that don't. Fortunately, about half of the flavors do not have this ingredient. That's why I am rating it a 6/10. You don't sell the natural anymore and that was my go to.

Pre JYM has been my pre workout since it’s inception. I use it for not only working out. But, for better focus and concentration when working on different projects.

Works very well for pump and endurance purposes. Tangerine tastes like orange juice, the black cherry is really good and the cherry lime is overbaringly favorful to the point where you need ice to make it drinkable.

This product is great. Does what I would expect in terms of getting me amped up and keeping me going through my workout but, unlike other products I’ve tried, is easy on my guts. The price is high but I’m happy enough with the product to pay it. With regards to flavours, I find the Raspberry Lemonade leaves a sweet aftertaste in my mouth for the rest of the day that I don’t appreciate so I won’t buy that flavour again. The Cherry Limeade doesn’t though so that’s become my go-to.

I have tried a lot of Pre Workouts, and PreJYM is the best out there, Honest ingredients, great flavors and real results to help me power through my workout with focus all without the itchy tingly issues that some overloaded stimulant packed Pre's can use to fool you into believe its working. This just works.... Great flavors, and ingredients backed by science and results not hype!
