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.*

10/10 on *flavor* for Orange Mango; one of the best tasting pre's I've had. 6/10 on effectiveness: the reviews about bloat and running to the bathroom are legitimate; this doesn't seem to impact everyone that uses it, but it does for a significant number of people. Other than that, focus/pump etc was on par with other well-known pre's (kage, etc).

Pre JYM is simply the best Pre Workout product on the market; a perfect 10 out of 10. I submitted a lengthy review of this product years ago (not sure why I cannot modify it) but this review is merely an update on the new flavors I've been trying.

I think this is an excellent product. I never feel jittery and have excellent focus, energy, and pumps. Will definitely buy again. However, the tangerine flavor literally tastes like vomit. I struggle to get it down. It is the worst tasting pre-workout I have every tried. I have no idea how this flavor is so highly rated.

Somedays it tastes better than other days, but there is no doubt the pump you get is insane.

By far, the best preworkout product I have been able to tolerate that does not give me jitters. Most of the flavors I have tried, I have enjoyed. I do have a preference for Tangerine though. I highly recommend this product. The amount of alertness and energy I get throughout the day is amazing.

Guys! I kinda have to get this because I'm following Jym's programs and he recommends these. But I hate the tastes. I wish there was a tasteless option for these products. Please let me know if you know any substitutes with similar materials and ratio, and less sugar and artificial tastes.

Not bad but gave me stomach issues and never really felt an increase in energy after taking.

I took this and it doesn't help me focus at all. I do not get any benefit out of this pre-workout. This pre-workout had me running to the bathroom and made me bloated. It did not help me workouts it only hindered it. I thought at first when I took it maybe it was just me, but I took it multiple times now and I keep running to the bathroom with it. It just makes me feel bloated. The scoops are huge. I feel like they just put a lot of fillers with this pre-workout. I hate throwing stuff away, but if I have to use the bathroom multiple times after taking it I had to just throw it away. I hate giving one star reviews because I feel like its bad but if I had to throw it away there is something wrong with the product. I have taken the EVL - Shred pre-workout and I had no problems. I was just looking to change it up a bit and see if there was anything better, but I would stay away from this one. I know it says best seller, but it's not worth it at so many different levels. I really wanted this one to work, but it didn't for me not saying it won't for you, but this was my experience with this product.

Not a caffeine person? Then stay away, if not Stay awake the whole night. the product gives a good pump but i never could continue using it due to the high caffeine volume that kept me awake at whatever the time i took this. even the day i took it around noon i coudlnt sleep until 3-4am. but other than that it's good stuff.
